Title: Method for communication in a machine tool system and a communication system therefor

Description:
TECHNICAL FIELD 
     The present disclosure relates to a method for establishing communication in a machine tool system and to an apparatus for performing the method and a computer program for establishing communication in a machine tool system. 
     BACKGROUND 
     A machine tool is a machine for shaping or machining metal or other rigid materials such as plastics, composites, ceramics not limiting to other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of processing. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus the relative movement between the workpiece and the cutting tool is controlled or constrained by the machine to at least some extent. 
     Computer Numerical Control (CNC) is widely used for controlling machine tools made for manufacturing, both additive and subtractive, wherein operations such as drilling, milling, turning, reaming, threading or grinding are common A CNC machine alters materials, for example, metal, plastic, wood, ceramic, or composite etc. to meet precise specifications by following programmed instructions and without a manual operator. In general, a CNC comprises at least one Numerical Control (NC) that controls numerical programmed motions and one Programmable Logic Controller (PLC) controlling logical based functions. 
     Nowadays, in CNC systems, the design of a mechanical part and its manufacturing program is highly automated. The mechanical dimensions of the part are defined using CAD software, and then translated into manufacturing directives by Computer Aided Manufacturing (CAM) software. The resulting directives are transformed by “post processor” software into specific commands necessary for a particular machine to produce the component, and then loaded into the CNC machine. To summarize, CNC machines combine a motorized maneuverable tool and often a motorized maneuverable workpiece, which are both controlled by a NC, according to specific input instructions. Instructions are typically delivered to a CNC machine in a form of G-codes generated by a graphical Computer Aided Manufacturing (CAM) software, and executed in the NC as sequential programs. 
     To control the machine tools, a control node may be configured in such system. Nowadays, the establishment of communication between the control node and the machine depends much on specific manufacture of the machine. When any node in the communication is changed, the establishment of communication has to be changed according to the situation, which affects the efficiency of the system. 
     SUMMARY

     DETAILED DESCRIPTION 
       FIG. 1  shows a non-limiting overview of a machine tool system  10 , illustrating an exemplary embodiment. Machine tools may be milling machines, drilling machines and so on. Machine tools herein covers machines for both subtractive and additive manufacturing. The system  10  may comprise a control node  100 , comprising a transmitting unit  1001  for transmitting data signals and a receiving unit  1003  for receiving data signals. The control node  100  can be physically located inside a local machine tool system or remotely connected to the local machine tool system. The control node  100  may be, for example, a local computer, a server, a central located server, a cloud-based server, a virtual computer, etc. The data signals may be any type of data packets, for example including a header and payload, which are suitable for transmitting information in the machine tool system  10 , such as data packets based on Profibus, IEEE or TCP/IP etc. An exemplary structure of a data signal  400  is shown in  FIG. 2  wherein a header  402  and a payload  404  are included in the data signal. The functions of the header and the payload are the same as conventional data packets, which will not be described in detail herein. 
     In  FIG. 1  the machine tool system  10  may further comprise a CNC-machine  12 , also called machine tool or machine in this disclosure hereafter. The machine may further comprise a Programmable Logic Controller (PLC)  102 , comprising a receiving unit  1021  for reception of data signals and a relaying unit  1023  for relaying data signals and a Numeric Control (NC)  104  comprising a receiving unit  1041  for reception of data signals and a transmitting unit  1043  for transmitting data signals. The control node  100  is configured to exchange data signals with the machine to establish communication with the machine. The connection between the control node  100  and the machine tool system  10  may be a wired connection or a wireless connection. In different embodiments, the communication between the control node  100  and the machine tool system  10  may be based on Ethernet, according to IEEE 802.3, etc., or WiFi, according to 802.11, etc., Bluetooth, TCP/IP (Transfer Control Protocol/Internet/Protocol) not limiting to other suitable formats. 
       FIG. 3  shows an exemplary communication between the control node  100  and the machine  12  in the machine tool system  10 . The communication between the control node  100  and the machine  12  is bi-directional. Data signals sent between the control node  100  and the machine  12  are relayed over a routing unit  106 . The routing unit  106  may be any type of device having the function of routing, such as a PLC, a router, a device comprising machine tool relay etc. In the present disclosure, PLC is used as an example for relaying the data signals. The control node  100  and the machine tool system  10  respectively has a communication unit for communicating with each other. The routing unit  106  has a communication interface for relaying data between the control node  100  and the NC  104 . The communication between the control node  100  and the machine tool system  10  is established according to a method, which will be described in detail as follows. Other alternatives for the communication between the control node  100  and the machine  12  can also be adopted according to specific requirements and environments in this disclosure. For example, the control node  100  and the machine  12  can communicate directly without a routing unit  106  if the routing unit  106  is not necessary. 
     The communication between the control node  100  and the machine  12  is established by the process flow shown in  FIG. 4 . At S 100 , the machine tool system  10  notifies the control node  100  of an identifier of a machine  12  in the machine tool system  10 , said machine comprising a PLC  102  and a NC  104 ; then the control node  100  retrieves a machine configuration file comprising machine attributes based on the identifier at S 110 ; at  5120  the control node  100  determines a data structure for a data signal  400  transferring information in the machine tool system  10 , by interpreting the machine configuration file; and acknowledging from the control node  100  to the machine  12  that communication has been established at S 130 . In one embodiment, a ping command is required between the control node  100  and the machine  12 , preferably between the control node  100  and the PLC  102 , to make sure that the communication link is up and running. To detect if there is a communication error, a ping may be sent to the machine with a configurable time interval, it is only sent if there is no other PLC interface activity within this time interval. The ping may also be sent as a PLC ACK data signal to the PLC with a listed action type. The PLC  104  may send back an acknowledge with the same action type as soon as it detects a ping. Furthermore, data signals for a machine are defined by the number of tool carriers that can operate in the machine. Each tool carrier is defined as a channel. In some embodiments, the ping is only sent on the first channel in the machine data signal layout. 
     It may be different types of data signals exchanged over the communication interface. The data signals may be divided into classes by their use and characteristics. Some data signals may work as pure information carriers which in this disclosure will be called real-time data signal, such as a spindle speed, while others may have a clear and dedicated task which in this disclosure will be called action data signals. In various embodiments, action data signals may be used to start a process on either the PLC  102 , NC  104  or the control node  100 . The data signal class specification may also indicate the direction of a data signal which makes it possible to differentiate between inputs (to machine) and outputs (from machine) even though they basically deal with the same thing. 
     The data signal layout of the machine mentioned herein includes both data signals that are transmitted from the machine and data signals that are received by the machine. It should be understood that the specifications are non-limiting exemplifying embodiments, which are possible to be adapted by the person skilled in the art. For each kinematic feature of the machine, a subset of data signals is defined, the data signals are then mapped into memory areas in the machine control system. When defining the data signals for a machine, the kinematic is divided into the following data signal categories: machine identification, acknowledgement ACK actions, Not acknowledgement ACK actions, cutting tool feed rate, axis position and speed, axis load/power/torque and multiplicators for feed rate and spindle speed. 
     In an exemplifying embodiment, the action data signals and some real-time data signals for a machine are defined by the number of tool carriers that can operate in the machine. Each tool carrier is defined as a channel which has a corresponding set of data signals. Some real-time data signals are defined by the number of axes of the machine. Each axis has a corresponding set of data signals, one of each relevant real-time data signal per axis. The data signal of Machine identification is shown in Table 1.

     The serial number may be required to be sent serially in big endian byte order over the PLC interface with the bits representing PLC interface version to be sent first. Different machine control systems can store the data signals in its memory in different byte orders, the machine tool manufacturer is responsible for sending the serial number in the correct manner over the PLC interface. 
     The machine data signal layout and metadata for the machine are gathered in a machine configuration file. The machine configuration file can be located anywhere according to users&#39; need. For example, it is located on the control node  100 , or in a database or any other storage suitable for storing configuration files. 
     For the control node  100  and the PLC  102  to correctly process the data signals sent back and forth it is advantageous if the machine configuration file includes information of which byte order the PLC  102  uses to send and receive data signals. Based on this information the data signals sent over the PLC interface will be translated to and from the machine. See Table 3 for the supported byte orders, big endian is the preferred byte order. The machine identification data signals are always required to be sent with big endian byte order, regardless of which byte order is used in the PLC  102 .

       FIG. 7  illustrates an example of a 5-axis milling machine, wherein  702  is a tool spindle and  704  is a workpiece. An example of a data signal layout for the 5-axis milling machine is also shown in Table 19-20. The kinematic structure of this machine includes a workpiece with two linear axes (X, Y) and one rotary axis (C/S2), and a spindle (S1), with one linear axis (Z) and one rotary axis (B). 
     The rotary axis (C/S2) can change functions between position mode and speed mode. The position mode and speed mode share the same real-time output signal in default machine configurations. It is possible to set the two modes to two separate real-time output signals if this is required by the machine tool manufacturer. This example machine uses two separate signals for position mode and speed mode as seen in axis C and spindle S2. This example machine outputs feed power [W].

An example of a data signal layout for the 3-axis gantry milling machine is also shown in Table 23-24. The kinematic structure of this machine includes a stationary workpiece and a spindle (S) with three linear axes (X, Y, Z). 
     Movement in the X axis is driven by two separate motors which requires separate load/power/torque data signals. This example machine outputs feed load [%].

       FIG. 12  illustrates an example of a multitask TurnMill machine, wherein  1202  is tool spindle,  1204  is workpiece spindle and  1206  is tool turret. An example of a data signal layout for the multitask TurnMill machine is also shown in Table 29-30. The kinematic structure of this machine includes a tool spindle (S3) with three linear axes (X1, Y1, Z1) and a rotary axis (B), one tool turret with two linear axes (X2, Z2), two workpiece spindles with rotary axes (C1/S1, C2/S2) with a linear axis (Z3). 
     The two rotary axes (C1/S1, C2/S2) can change functions between position mode and speed mode. This example machine outputs feed load [%].

     With reference to  FIG. 13  a communication establishing system  300  is shown. The system may comprise a communication interface  370 , which may be considered to comprise conventional means for communicating from and/or to the other devices in the network, such as Control node  100 , PLC  102  and NC  104  or other devices or nodes in a communication network. The conventional communication means may include at least one transmitter and at least one receiver. The communication interface may further comprise one or more repository  375  and further functionality useful for the communication establishing system  300  to serve its purpose as an apparatus for establishing the communication between the control node  100  and the machine tool system  10 . 
     The instructions executable by a processor  350  may be arranged as a computer program  365  stored in said at least one memory  360 . The at least one processor  350  and the at least one memory  360  may be arranged in an arrangement  355 . The arrangement  355  may be a microprocessor and adequate software and storage therefor, a Programmable Logic Device, PLD, or other electronic component(s)/processing circuit(s) configured to perform the actions, or methods, mentioned above. 
     The computer program  365  may comprise computer readable code means which, when run in the system, causes the communication establishing system  300  to perform the steps described in the method described in relation to  FIG. 4  The computer program may be carried by a computer readable storage medium connectable to the at least one processor. The computer readable storage medium may be the at least one memory  360 . The at least one memory  360  may be realized as for example a RAM (Random-access memory), ROM (Read-Only Memory) or an EEPROM (Electrical Erasable Programmable ROM). Further, the computer program may be carried by a separate computer-readable medium, such as a CD, DVD or flash memory, from which the program could be downloaded into the at least one memory  360 . 
     Although the instructions described in the embodiments disclosed above are implemented as a computer program  365  to be executed by the at least one processor  350  at least one of the instructions may in alternative embodiments be implemented at least partly as hardware circuits. Alternatively, the computer program may be stored on a server or any other entity connected to the communications network to which the control node  100  has access via its communications interface  370 . The computer program may than be downloaded from the server into the at least one memory  360 , carried by an electronic signal, optical signal, or radio signal. 
     It will be appreciated that additional advantages and modifications will readily occur to those skilled in the art. Therefore, the disclosures presented herein, and broader aspects thereof are not limited to the specific details and representative embodiments shown and described herein. Accordingly, many modifications, equivalents, and improvements may be included without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
