Exemplary networks include wired networks, wireless networks, cellular networks, local area networks, wide area networks, public switched networks, any other system whereby two or more computing devices may communicate, and combinations thereof. An exemplary public switched network is the Internet. Exemplary communication software 112 includes e-mail software, Internet browser software, and other types of software which permit machine tool controller 202 to communicate with other devices across a network.
Memory 270 further includes machine tool software 284. Exemplary machine tool software 284 is the WINMAX brand machine tool software available from Hurco Companies, Inc. located at One Technology Way in Indianapolis, Ind. Machine tool software 284 is capable of reading a one or more part programs 274 which provide the desired tool paths for machine tool apparatus 200 or the desired geometry of a part 260 to be made by machine tool apparatus 200.
Machine tool software 284 illustratively includes motion control software 286 and user interface software 288. Motion control software 286 interacts with the axis controllers 370, 372, 374, 376, and 378 of respective axis 250, 252, 254, 256, and 258 of machine tool apparatus 200 to control the movement of each of 250, 252, 254, 256, and 258, interacts with tool carousel 244 to select the appropriate tool 240 for use with each operation, the speed of the tool spindle 238, and other parameters of machine tool apparatus 200. In one embodiment, motion control software 286 is a real time software module which is based on RTX extension to WINDOWS available from Ardence, located at 14 Crosby Drive in Bedford, Mass. 01730-1451. Exemplary motion control software 286 is disclosed in U.S. Pat. No. 5,453,933, U.S. Reissue Pat. RE39,907; U.S. patent application Ser. No. 11/277,286; U.S. patent application Ser. No. 11/277,291; U.S. patent application Ser. No. 11/277,305; U.S. patent application Ser. No. 11/833,958; and U.S. patent application Ser. No. 11/833,971, the disclosures of which is expressly incorporated by reference herein.
User interface software 288 interacts with input members 276 and the output members 277 to receive and process inputs through I/O modules 272 and/or communication software 282 and to provide outputs to the output members 277 and remote devices through communication software 282.
In one embodiment, motion control software 286 and user interface software 288 are apart of a single software package. In one embodiment, motion control software 286 and user interface software 288 are separate software packages which communicate with each other. In the illustrated embodiment, motion control software 286 and user interface software 288 are separate software packages which pass information back and forth as represented by line 290 and line 292. In one embodiment, motion control software 286 is a real time application while user interface software 288 is an interrupt based application.
Machine tool controller 202 receives input data, such as a part program 274 which may also be stored on memory 270 and provides output data, such as position data for the various axes 250, 252, 254, 256, and 258 of machine tool apparatus 200. In one embodiment, machine tool controller 202 receives part program 274 through one or more I/O modules 272. In one embodiment, user interface software 288 receives the part program 274 and provides a representation of the part program 274 to motion control software 286 for interpretation and execution.
In one embodiment, part program 274 is entered through a conversational mode of operation whereby a user during a programming session is presented with one or more screens through a user interface (such as a touch screen and keyboard of I/O modules 272). An exemplary method of conversational programming is disclosed in U.S. Pat. No. 5,453,933, assigned to the assignee of the current application, the disclosure of which is expressly incorporated by reference herein. During the programming session, the user may program the desired geometry for the machined part 260 and specify one or more attributes. In one example, the user specifies the desired geometry for the machined part 260 by creating blocks of code each of which specifies a tool and a trajectory of the tool. As such, the geometry of the machined part 260 is defined based on the operations used to create the machined part.
In one embodiment, part program 274 is provided through a NC mode of operation whereby an NC program is loaded into machine tool controller 202. Part programs 274 are frequently expressed in a standard G&M code language, or a close derivative of this language based on either the International Standards Organization (ISO) or the Electronics Industries Association (EIA) RS-274-D, using codes identified by letters such as G, M, F. The codes define a sequence of machining operations to control motion in the manufacture of a part 260. Machine tool controller 202 converts the codes to provide location positions for the various axes 250, 252, 254, 256, and 258 of machine tool apparatus 200. In one embodiment, part program 274 is parsed by a parser of machine tool controller 202 which reviews the part program 274 and identifies various geometry segments. Exemplary geometry segments include lines, arcs, splines and other suitable types of segments.
Regardless of the origin of part program 274, part program 274 defines the desired geometry for the machined part 260 either directly or based on the operations used to create the part 260. However, part program 274 may not specify the positions of saddles 204, 210, and 226 nor the rotations of platform 220 and rotatable member 232. These positions are determined by machine tool controller 202. A user of the machine tool system (or user interface 450 discussed herein) may select one or more of the part programs 274 stored on memory 270 for uploading to memory 294 of remote controller 296 for storage as a backup copy of the one or more part programs 274.
Memory 270 further includes monitoring software 291 which is discussed herein. Monitoring software 291 of machine tool system 106 communicates with a remote monitoring software 293 across a network 150. Remote monitoring software 293 is executed by a remote controller and is provided on a memory 294 which is accessible by remote controller 296. Exemplary remote controllers include a server or any other computing device capable of communicating with machine tool controller 202 over network 150. Remote controller 296 may be a single computing device or may be a plurality of computing devices.
In one embodiment, monitoring software 291 through communication software 282 initiates a data connection with monitoring software 293. By having machine tool controller 202 initiate the connection with remote controller 296, remote controller 296 does not require knowledge of the facility network interface 120 of the respective first representative facility 102. Facility network interface 120 includes the firewalls, routers, and other network and security components positioned between machine tool systems 106 and 108 (and other networked devices of the facility) and network 150. It is very likely that a facility network interface 122 of facility 110 has different topology and security than facility network interface 120. As such, by having the respective machine tool controllers initiate the connection with remote controller 296, remote controller 296 does not need to have knowledge of the specifics of each of facility network interface 120 and facility network interface 122.
As remote controller is in communication with machine tool systems from different customers, each having their own internal network security provisions, by having the machine tool system contact the remote controller 296 the machine tool provider 116 does not require knowledge of each customer's network settings. This allows remote controller 296 to communicate with each of machine tool system 106 and machine tool system 108 of first representative facility 102 and machine tool system 112 and machine tool system 114 of second representative facility 110 even though each of first representative facility 102 and second representative facility 110 have different security measures in place. In one embodiment, the data connection is a one-way connection in that machine tool controller 202 simply pushes information to remote controller 296 which is then stored in one or more databases 298. In one embodiment, the data connection is a two-way connection in that machine tool controller 202 may push data to remote controller 296, but remote controller 296 may also send communications to machine tool controller 202 such as to change parameter values associated with the machine tool system 106, set events to monitor for, request information, and perform additional tasks. In one embodiment, the two-way data connection is established by the machine tool system during system startup as discussed herein.
Referring to FIG. 4, the interaction between machine tool controller 202 and remote controller 296 is represented. Machine tool controller 202 when the machine tool system 106 is powered up checks to see if a network is available as represented by block 310. If a network is not available, machine tool controller 202 continues to query for available networks over time. Irrespective of whether a network is available, machine tool system may operate as a stand alone system. As such, the machine tool system inability to connect to remote controller 296 will not impede the machine tool system from executing one or more part programs 274.
If a network is detected, machine tool controller 202 attempts to connect to remote controller 296 as represented by block 312. Remote controller 296 receives the request to connect from machine tool controller 202 and determines whether the machine tool system 106 is authorized to connect to remote controller 296, as represented by block 314. In one embodiment, the request from machine tool controller 202 includes a machine identification number which identifies the machine tool system 106 which the machine tool controller 202 is associated. One exemplary machine identification number is based on unique information of the machine tool system 106 itself Exemplary unique information includes a hard drive serial number of memory 270, a hardware address of the machine tool system 106, and an install time of operating system software 280 of the machine tool system.
Exemplary machine tool identification numbers are disclosed in U.S. patent application Ser. No. 12/103,680, filed Apr. 15, 2008 titled SOFTWARE OPTIONS SELECTION AND VALIDATION SYSTEM, the disclosure of which was expressly incorporated by reference herein. The machine tool identification number is also stored in memory 294 associated with remote controller 296. If the machine identification information received in the request from machine tool controller 202 does not match a machine identification number stored in memory 294 associated with remote controller 296, remote controller 296 sends a communication to machine tool controller 202 that the request to connect has been denied, as represented by block 316.
In response thereto, machine tool controller 202 provides an indication to an operator of the machine tool system 106 that the requested connection to remote controller 296 has been denied, as represented by block 318. Machine tool controller 202 may continue to still attempt to connect to remote controller 296 as represented by line 319. In one embodiment, these additional requests to connect to remote controller 296 are performed automatically. In one embodiment, these additional requests to connect to remote controller 296 are based on input received from an operator of the machine tool system 106.
If the machine identification number received from machine tool controller 202 matches a machine tool identification number stored in memory 294 associated with remote controller 296 then a data connection between machine tool controller 202 and remote controller 296 is established. In one embodiment, this data connection is a two way data connection which permits information to be passed from machine tool controller 202 to remote controller 296 as well as information to pass from remote controller 296 to machine tool controller 202.
In response to machine tool controller 202 connecting with remote controller 296, remote controller 296 updates a status of machine tool system 106 as active, as represented by block 318. In one embodiment, the status of machine tool system 106 is stored in a database 298 stored on memory 294.
Referring to FIG. 5, an exemplary collection of information 320 about machine tool system 106 stored in database 298 is shown. In one embodiment, the collection of information is stored in various tables of databases 298. As shown, part of the collection of information 320 regarding machine tool system 106 is an indication of whether the machine is active or not, as represented by block 322. Also the machine ID is included, as represented by block 324. Customer information is included, as represented by block 326. Exemplary customer information includes name and address of the customer contact information users and passwords and other information related to the customer. User information, such as access to machine tool system 106, is included, as represented by block 420.
Returning to FIG. 4, remote controller 296 checks to see if it has information to send to the machine tool controller 202 as represented by block 328. As explained here, exemplary information may include files such as part programs 274 to be provided to machine tool controller 202, updated parameter values to associate with machine tool system 106, and parameters to add to a watch list. If remote controller 296 has information to send to a machine tool controller 202, machine tool controller 202 receives this information from the remote controller 296, as represented by block 330, and then performs any steps required. In one example, the information sent from remote controller 296 to machine tool controller 202 is a parameter to monitor with monitoring software 291. As such machine tool controller 202 adds this parameter to a listing of parameters being monitored.
In addition, remote controller 296 provides an indication to machine tool controller 202 of whether the machine tool system 106 is being observed by one or more remote users, as represented by block 332. As explained herein, remote users have the ability to connect to remote controller 296 and to view information regarding the machine tool system 106. If the machine tool system 106 is being observed, machine tool controller 202 receives an indication that the machine tool system 106 is being observed, as represented by block 334. In one embodiment machine tool system 106 provides an indication to an operator that the machine tool system 106 is being observed.
In response to machine tool controller 202 being connected to remote controller 296, machine tool controller 202 gathers and sends information to remote controller 296, as represented by block 336. Remote controller 296 receives the information sent by machine tool controller 202 and updates the database information regarding the machine tool system 106, as represented by block 338.
Referring to FIG. 6, a representation of monitoring software 291 is shown. Monitoring software 291 may be represented as a plurality of grabbers which obtain the information to be monitored and/or sent to remote controller 296. Exemplary grabbers include a software identifier (SID″) grabber 340, an axis grabber 342, an image grabber 344, a file grabber 346, an acoustic grabber 348, and a vibration grabber 350. An explanation of each of these exemplary grabbers is provided herein.
Referring to FIG. 7, an exemplary SID grabber 340 is shown. As mentioned herein, machine tool software 284 includes motion control software 286 and user interface software 288. As mentioned herein, information is exchanged between motion control software 286 and user interface software 288, as represented by lines 290 and 292. This exchanged information may be thought of as motion control data 352 and user interface data 354. SID grabber 340 monitors the information exchanged between motion control software 286 and user interface software 288 as represented by bridge 356. In particular, the SID grabber 340 through bridge 356 looks to see if various values for parameters it is watching are passed between motion control software 286 and user interface software 288. The parameters to watch 358 include default parameters 360 which are always monitored by monitoring software 291 and requested parameters 362 which are additional parameters requested to be monitored by remote controller 296. If a value of one of the parameters to watch 358 is passed between motion control software 286 and user interface software 288, SID grabber 340 copies the value of that parameter and stores it for sending to remote controller 296. The values of the monitored parameters are stored in database 298, as represented by block 364 in FIG. 5.
Referring to FIG. 8, a representation of an exemplary axis grabber 342 is shown. Axis grabber 342, like SID grabber 340, has access to a listing of the parameters to watch 354. Axis grabber 342 communicates with the machine tool systems axis controllers, such as servo-amplifiers, and extracts configuration and tuning data therefrom. Each of axis 250, 252, 254, 256, and 258 have a respective axis controller 370, 372, 374, 376 and 378. The data regarding this configuration and tuning data 371, 373, 375, 377, and 379 of the axis controllers 370, 372, 374, 376 and 378. is gathered and transmitted to remote controller 296 and is stored in database 298 as represented by the block 396 as shown in FIG. 5.
Referring to FIG. 9, image grabber 344 is represented. Image grabber 344 gathers image information from one or more cameras 384 and I/O modules 272. Exemplary cameras include still image cameras and video cameras. In one embodiment, cameras 384 are mounted on mounts that permit the orientation of the camera to be changed based on input from remote controller 296. As shown in FIG. 9, in one embodiment, I/O modules 272 include a first display 278 and a second display 279. In one embodiment image grabber captures either a screen shot of display 278 or a screenshot of display 279, or a screen shot of both display 278 and 279. Image grabber 344 provides the stored images to the remote controller 296. The image data is stored in database 298 by remote controller 296 as represented by block 385 in FIG. 5. In the illustrated embodiment, the images provided to remote controller 296 provide a passive look at the current operation of the machine tool system. In one embodiment, a user of remote controller 296 is able to proxy onto the machine tool system and take active control of the current operation of the machine tool system. In this manner, a remote technician may actively change settings of the machine tool system.
Referring to FIG. 10, machine tool apparatus 200 is shown housed in a cabinet 386. Cabinet 386 protects operators from the moving components of machine tool apparatus 200. On a front side 388 of cabinet 386, I/O modules 272 are provided. Further, a door 390 is provided in cabinet 386 permitting access to machine tool apparatus 200 by an operator. In general, an operator remains in an operator area 392 represented by the dash lines in FIG. 10. A first camera 384A is positioned inside of cabinet 386 and is directed to view the operation of machine tool apparatus 200. A second representative camera 384B is shown monitoring operator area 392 on an exterior of cabinet 386. As such with image grabber 344, a remote viewer may observe the information viewable by an operator on display as 278 and 279, the actions being taken by an operator with camera 384B and actions being taken by machine tool apparatus 200 with camera 384A. In this manner a service technician may observe the steps being taken by the machine tool operator to make sure the requested steps (provided by the technician, such as over the phone) are being carried out.
Referring to FIG. 11, a representation of acoustic grabber 348 is shown. Acoustic grabber 348 monitors the output of a microphone 394 and provides a representation of that audio information to remote controller 296. The received audio data is stored in database 298 as represented by block 296 in FIG. 5. Referring to FIG. 10, microphone 394 is shown placed within cabinet 386 and proximate to machine tool apparatus 200.
Referring to FIG. 12, a representation of vibration grabber 350 is shown. Vibration grabber 350 monitors one or more vibration sensors 398. The vibration information collected by vibration grabber 350 is provided to remote controller 296. Remote controller 296 stores vibration data in database 298 as represented by block 400 in FIG. 5.
Referring to FIG. 13, the transmission interval of data to remote controller 296 may be varied based on whether the machine tool system 106 is being observed or not. In one embodiment, each of the respective grabbers continues to grab the data it is monitoring for irrespective of the transmission interval to remote controller 296. In one embodiment, one or more of the grabbers alters the interval at which it monitors for information to coincide generally with the interval that such information is passed through remote controller 296. In one embodiment, at least a portion of the grabbers do not monitor and capture data unless specifically requested by remote controller 296. One example is file grabber 346 which only provides directory information of memory 270 to remote controller upon request.
As shown in FIG. 13, a determination is made whether the machine tool system 106 is being observed as represented by block 410. If the machine tool system is being observed the time interval for passing information to remote controller 296 is set to a higher frequency, as represented by block 412. If the machine tool system is not being observed, the time interval for passing information to remote controller 296 is set to a lower frequency as represented by block 414. In one embodiment, the higher frequency has a time interval of five seconds while the lower frequency has a time interval of about 12 hours. In one embodiment, the time interval spacing of the lower frequency is at least ten times the time interval spacing of the higher frequency. In one embodiment, the time interval spacing of the lower frequency is at least 100 times the time interval spacing of the higher frequency. For either time interval, machine tool controller 202 gathers the information collected by the grabbers and sends that information to remote controller 296 as represented by block 416. This is repeated for each time interval as represented by block 418. A change in the status of the machine tool being observed will result in the time interval that information is collected and/or sent to remote controller 296 to be adjusted. In the illustrated embodiment, image grabber 344 does not provide streaming video to remote controller 296, but rather images at the respective time intervals. In one embodiment, image grabber 344 provides streaming video to remote controller 296.

Remote controller 296 compares the collected information received from the machine tool system with the provisions of the warranty to determine if an alert condition exists. In the case of a tool spindle, remote controller 296 compares the collected running time of the tool spindle to a suggested running time of the spindle without lubing the tool spindle. If the collected running time of the tool spindle is approaching the suggested running time or has exceeded the suggested running time an alert condition is set and an alert notification should be sent. In one example an alert notification is sent when the running time of the tool spindle is within about ten percent of the suggested running time of the spindle. In one embodiment, an alert notification is sent to a user responsible for preventative maintenance of the machine tool system and/or a user responsible for warranty compliance, if not the same user, to provide an indication of the alert. In one embodiment, the user of user interface 450 may request to be notified of warranty alert conditions. This may be accomplished by including preventative maintenance parameters to the listing of input 600 in FIG. 29 and selecting the corresponding notification delivery with input 602.

By selecting graphical icon 538, a directory and file listing of memory 270 is presented in presentation area 506 as shown in FIG. 28. A user of user interface 450 is able to browse through the directory and file structure in a similar fashion to the WINDOWS brand family of software available from Microsoft Corporation. A user may delete files from memory 270 or upload files to memory 270. In one embodiment, a user will only be able to delete files that they have rights to delete. For example, a user may delete their own part files. A machine tool manufacturer representative may delete files associated with software 271. In one embodiment, a user may retrieve files from memory 270 to view their contents.
By selecting graphical icon 540, an edit event input is displayed in presentation area 506, as shown in FIG. 29. A first input 600 provides a plurality of events for the user of the user system to select. A second input 602 provides a plurality of methods by which the user of the user system should be notified of the occurrence of the event selected with input 600. The events correspond to a condition of the machine tool system and are tied to the user whom selected to be notified thereof. In one embodiment, events may be set for a group of users. In one embodiment, a notification of a given event may be automatically sent to a given user based on that user's responsibilities. For instance, a service technician may automatically receive notifications of all preventative maintenance reminders and parameters out of range, such as fluid levels. As another example, a machine tool operator may automatically receive a notification that the part program 274 being executed failed. In one embodiment, the determination of whether the part program 274 being executed failed or not is made by the process of monitoring for an error code issued by the motion control software. The issuance of an error code will be in response to a failure of the part program. In one embodiment, the determination of whether the part program 274 being executed failed or not is made by the process of monitoring a time of the current cycle of the program and comparing that to an estimated cycle time of the program and determining that the part program 274 failed when the current cycle time exceeds the estimated cycle time.
In one embodiment, the user may select a notification method that sends a notification to a user device other than the user device being used to access user interface 450. In one example, a user interacts with user interface 450 through their office computer and requests notifications sent to their cell phone as a text message because they are going to be out of the office that day.
In one embodiment, the events selectable through input 600 correspond to event markers included in a part program. Referring to FIG. 31, a portion of an exemplary part program 610 is shown. Part program 610 includes a plurality of instructions 612, 614, 616, 618, 620, and 622 and two event markers, illustratively event marker A 624 and event marker B 626. Each of instructions 612, 614, 616, 618, 620, and 622 may correspond to providing instructions regarding the tool to use for the next operation or may correspond to the a path for the tool to follow. In one embodiment, event marker A 624 and event marker B 626 are specific M codes. In one embodiment, four event markers are provided, M codes M1, M2, M3, and M4. These markers may be placed in part program 610 to provide any indication of a completion of one of instructions 612, 614, 616, 618, 620, and 622. The M codes are simply one type of event marker.
A customer may utilize the M codes as desired. For instance, M1 may always be used to indicate the end of part program 610 while M2 may always be used to indicate the end of a cycle of part program 610. In one embodiment, the M codes may be used in a random manner.
Returning to FIG. 29, a user selects one of M codes M1, M2, M3, and M4 from input 600. With input 602 the user selects a notification method for the event selected with input 600. The user may then save the event by selecting input 628. By selecting input 628, remote controller 296 stores in database 298 the event to be monitored for and the requested notification method. Remote controller 296 also notifies machine tool controller 202 to add the event to a listing of the parameters to watch. In one embodiment, machine tool controller 202 always reports the occurrence of one of the M codes M1, M2, M3, and M4 and remote controller 296 then only provides a notification to those users which selected to be notified about the respective M code.
Referring to FIG. 32, exemplary notification methods are shown. A first exemplary notification method is a communication to the user, as represented by block 630. Exemplary communications to the user, include an e-mail message 634 and a text message 636. Additional exemplary types of notification include a voice message, a page, and other suitable methods of communicating the occurrence of the event to the user. A second exemplary notification method is logging, as represented by block 632. Exemplary logging includes a history of the events. In one example, the user may select to have a descriptive textual label saved in a log along with time of occurrence information if a corresponding event occurs. This textual label would be viewable at a later time. This would be useful if a user does not have constant access to a notification device, such as a cell phone, and is only able to periodically check the occurrence of events through user interface 450.
Referring to FIG. 30, an event log 640 is shown. The event log 640 provides a listing of all events which have been detected in a given time period. As shown in FIG. 30, the event log provides all events which have been detected for the last fourteen days. The log provides the time of each event, the parameter causing the event, the notification action to take in addition to logging, and the destination address to use for the notification action.
The operation of the remote controller 296 in setting events is represented in FIG. 33. Remote controller 296 receives an indication of an event to monitor for the occurrence of at the machine tool system, as represented by block 650. In one embodiment, the indication is received in response to a user selecting input 628. In one embodiment, the indication is received based on the user's occupation. For instance, a service technician will automatically receive all service events. Remote controller 296 further receives an indication of the desired notification mechanism for the event, as represented by block 652. In one embodiment, the indication is received in response to a ser selecting input 628. In one embodiment, the notification mechanism was provided in the user data 420 in collection of information 320 of database 298.
Remote controller 296 sends a communication to monitoring software 291 of the machine tool system to monitor for an indication of the event, as represented by block 654. In one embodiment, the remote controller 296 notifies the monitoring software 291 to monitor a parameter which will be used as the indication of the event. Remote controller 296 upon the occurrence of the event receives the parameter value or other indication, as represented by 656. In one embodiment, wherein the event is based on an M code, the processing of the M code is communicated to remote controller 296. In one embodiment, wherein the event is based on a parameter value, monitoring software 291 sends the value of the parameter at each time interval. Remote controller 296 determines based on the received value whether the corresponding event has occurred or not. In one embodiment, monitoring software 291 determines whether the event has occurred or not. In response to the detection of the event, remote controller 296 sends a notification to the user of the occurrence of the event, as represented by block 658.
In one embodiment, when each machine tool system connects to remote controller 296, the machine tool system provides the current version of each of the components of software 271 to remote controller 296. If remote controller 296 has a newer version of any of the components of software 271, remote controller 296 updates the respective machine tool system. In one embodiment, remote controller 296 downloads the updates to the software and installs the updates with an install shield utility. In one embodiment, remote controller 296 queries the operator of the machine tool system prior to downloading the updates to the software to the machine tool system. In one embodiment, the updates are customer dependent because one customer may have different software options from another customer.
In one embodiment, machine tool system must register with an authorized representative of the machine tool provider 116 prior to downloading updates to the software 271. Referring to FIG. 34, an exemplary process for updating the software of a machine tool system is shown. An update utility 650 is launched on a desktop 652 of software 271. The machine tool system is connected to machine tool provider 116 through the Internet. The operator of the machine tool system attempts to perform an upgrade with upgrade utility 650 as represented by block 654. The request is denied by the remote controller 296 of the machine tool provider 116 because the machine tool system has not been registered for upgrades.
In response, the operator of the machine tool system provides customer information 656 to an authorized representative 658 of the machine tool provider 116, as represented by block 660. The authorized representative 658 verifies the received customer information with an authorization system 662. In one embodiment, the customer information is a machine tool identification number which is based on the characteristics of the machine tool system as discussed herein.
If the received customer information matches the information available to authorization system 662, the remote controller 296 of machine tool provider 116 provides a notification 664 to the machine tool system that the authorization was successful, as represented by 668. In one embodiment, the notification is a message displayed on desktop 652.
Once authorized for updates, a customer checks for updates, as represented by block 670. This request is received by remote controller 296 and a check is made whether the customer is authorized for updates. If not authorized, a notification is returned to machine tool system that the updates were denied. If authorized, then remote controller 296 sends the updates to software 271 and installs the software automatically, as represented by block 672. In one embodiment, the operator is prompted to determine whether to install updates automatically or to delay the installation. In one embodiment, the operator is prompted with a listing of available updates to which the operator selects one or more update from the listing.
In one embodiment, the updates are pushed down by the machine tool provider instead of initiated by the operator of the machine tool system. in this embodiment, software 271 determines the current version of each of the software modules and sends this information to remote controller 296. Remote controller 296 then pushes down any available updates to the machine tool system.
Referring to FIG. 35 and FIG. 36, another exemplary method of updating software 271 and/or part programs 274 stored on memory 270 is provided. Memory 294 associated with remote controller 296 includes software 700 which corresponds to one or more of the software systems of software 271 of the machine tool system and part programs 708. As shown in FIG. 35, memory 294 includes software 700 having a plurality of files 702-706. Whenever an update is available for software 700, it is installed and stored on memory 294.
Referring to FIG. 36, a comparison is made between files stored on memory 296 marked for syncing and the files stored on memory 270, as represented by block 750. In one embodiment, the comparison is made by remote controller 296. In one embodiment, the comparison is made by the machine tool system.
The files marked for syncing are shown in double outline in FIG. 35. In one embodiment, a file is marked for syncing based on its location in a file structure of memory 294. For instance, memory 294 may include a directory and associated sub-directories which contains all of the files which are to be synced to the machine tool systems.
As shown in FIG. 35, part program files may also be synced to the machine tool systems. In this manner, a customer may download a given part program to all of their machine tool systems. Since customer files are generally specific to a given customer, memory 294 may store the part program files to be synced separately from software 700 and then make a separate check to see if any client specific files (part programs 274) for the respective client need to be synced. In the illustrated example, file 713 is stored on memory 296 and marked for syncing. A prior version of file 713 does not exist on memory 270. That said, copying a new file to memory 270 and replacing an out-of-date file on memory 270 are each types of syncing.
For all files marked for syncing which differ between memory 294 and memory 270, a copy of the file is downloaded to memory 270, as represented by block 752. Relative to software 271 on the machine tool system, this differs from the concept of downloading updates and subsequently installing the updates. By syncing software 271 with software 700, copies of the already installed version of the software are downloaded and ready for execution without the need for a subsequent installation.
In one embodiment, checks are made at spaced apart syncing intervals to see if any files on the machine tool system have an updated copy on memory 294, as represented by block 754.
In one embodiment, a user of a user system or a user of remote controller 296 is able to control the operation of the machine tool system remotely. Exemplary actions include starting a part program.
