Machine Setup/Maintenance (MakerBot)

Main Article: 3D Printing
Makerbot prints by heating plastic and placing it in layers on the base plate. For this to work the machine must be printing onto a level plate, have enough filament, and maintain proper temperature.

==Steps for Printing==
|-
|colspan="2"|
==Secure Machine==
Makerbot shakes while making parts. If the machine is not secure this can create part deficiencies. Level machine by using a level or simply verify it doesn’t wobble.
|-
|colspan="2"|
==Maintaining Tape==
|-
|style="vertical-align:top;"|
Masking tape is used on the tray of the MakerBot to make maintenance easier. At the beginning of every print the take a credit card and verify there are no bubbles in the tape and that is it laying flat. Remove bubbles if present. If the tape looks worn and replace it. Tape wears from pulling parts off, heat from the nozzle, and getting oils from hands on it.
Blue masking tape can be found by asking around with the mechanical engineering faculty in Gauss Johnson. When placing new masking tape on the tray make sure it is flat. Any bubbles or overlaps will deform part bases. Also, leave the left front corner tape free. This allows the plastic to stick to the tray ensuring any plastic floating around the nozzle doesn't effect the print.
|
|-
|colspan="2"|
==Leveling Base Tray==
The base plate must be level to avoid lopsided parts. The base plate should only be leveled if the second print attempt fails. If the print fails the first time, try lightly lifting the front left corner of the tray so it is almost touching the nozzle. This is necessary because the base plat is warped.
On the main menu, select "Utilities → Leveling" and follow the instructions. When using a paper to check height the friction should be similar to using a set of feeler gauges.
|-
|colspan="2"|
==Loading/Unloading Filament==
The filament will need to be unloaded/loaded if the user wishes to change the color or no filament is loaded. The load/unload commands can also be used to fix a jammed printer nozzle by unloading and reloading filament. Users should go through the load command whenever building parts even if filament is already loaded. This verifies the nozzle is not clogged. Filament should flow freely. 
===Loading Filament===
To load filament, run the load command, on the main menu, select "Utilities → Change Filament → Load" and follow the directions.
===Unloading Filament===
To unload the filament, on the main menu, select "Utilities → Change Filament → Unload" and follow the directions.
|-
|colspan="2"|
==Preheating==
Before starting the part, the machine must be heated to the proper temperature for the plastic to flow properly. Typically the Machine will run between 220°-230°C. To preheat select "Preheat" on the main menu.

Mastercam Drilling Operations

One very common machining process, and one of the easiest to set up in Mastercam, is drilling out holes. This tutorial will show you how to create a drilling toolpath in Mastercam X7.
Image	Step
 	
You can select a toolpath by either following the process shown to the left, or by clicking on 'Toolpaths' in the uppermost toolbar.
 	
Mastercam will now allow you to name your toolpath. Enter something that makes sense to you if you have to come back and edit your toolpaths. Click on the check mark when you're done.
 	
Mastercam will now ask you to select the locations to drill at. It is usually easiest to choose Select Entities, then click on the edges of the circles you would like to drill. Be sure to click on them in the order in which it will be machined most efficiently. It may be easier at this point to switch to a wireframe view. Click the check mark once all points have been selected. Make sure you set up a centerdrill toolpath before setting up a drilling toolpath.
 	
When the next window opens, click Drill, then click on 'Tool'. Next, click 'Select Library Tool' and find your tool in the library and double-click it. If you cannot find the tool you need, uncheck the 'Filter Active' box.
 	
Make sure the correct tool is selected in the window, then correct 'Tool #','Feed rate', and 'Spindle speed'. Feed rates and spindle speeds can be found using the charts in the machine shop and are based on tool, tool size, and material on a mill, and tool, material, and material size on a lathe.
 	
When you're done with tool setup, click cut parameters, and set the cycle to peck drill and set your peck depth.
 	
Next, click on Linking Parameters, and select 'Absolute' for every section, and fill in the blank sections. Depth should always be a negative number.
 	
Next, click on planes and make sure all three planes display "TOP".
 	
In the Coolant window, set 'Flood' to 'On'. You are now done the centerdrill toolpath. Click the check mark, then repeat this process with a drill instead of a centerdrill.

Mastercam Lathe Grooving Operations

This tutorial will walk you through how to create grooves on the CNC lathe through the Mastercam software.
{|width=”100%” border="2"
|-
! Image !! Step
|- align="center"
| ||
Expand the General gallery, and select Groove from the Lathe Turning tab. The Grooving Options dialog box opens. Select the Multiple Chains option from the Grooving Options dialog box and hit ok.
|-
|- align="center"
| ||
You will be prompted to select an entry point for the groove tool. You can chain multiple grooves together in one operation by selecting the first and last entities of each chain as shown.
The shortcut [Alt + T] toggles the toolpath geometry display.
|-
|- align="center"
| ||
Right click in the Toolpaths Manager. Select Lathe Toolpaths, and Groove. From here, you must select the proper grooving tool that will be used in the CNC lathe when the part is machined. It is typically ok to leave all other parameters on this page at their default values. The other tabs on the Groove Toolpaths can be used to adjust how the groove will be shaped and how it will be cut. Typically, the first grooving cut will be a roughing cut, so this tab can be used to create the roughing toolpath. Mastercam will create roughing and finish toolpaths for you as long as the corresponding tabs have the correct values for each pass. If only a roughing pass is desired, then you can clear the Finish option on the Groove Finish Parameters page.
Mastercam Lathe Setup

First, begin opening the part file in MasterCam. Use the drop down bar to select All Files (*.*) to show all of the files in the folder. MasterCam does not require the part to be saved as a different file type than SolidWorks saves as. Select the part that will be operated on, and then save the MasterCam file before work begins.
Once the file is loaded, the machine must be selected. From the Machine tab across the top, select the Lathe. The CNC lathe that will be used to cut the part must be selected correctly.
Multiple machine groups can be created on one file, so you can create as many as needed to stay organized. Right clicking the machine group will allow you to rename it to whatever is desired.
==PART ORIENTATION==
Image 	Step
350px 	
Now that the initial setup is completed, the part must be oriented. Right clicking and changing the GView will allow you to see the part at a different angle. Go to the transform tab and select Dynamic to open its function panel.
350px 	
Select the part and place the dynamic gnomon on the origin of the part. This will allow you to move and rotated the part about the axes. Select move from the function panel to move the part. Clicking in the center of the curved control axis will allow rotation of the part, and clicking on the straight axes will allow translation motion. The graphics window will display a preview. On the function panel, click ok to accept the transformation.
center|350px	
Sometimes this will change the color pf the part. It can be changed back to the original by entering the mini toolbar and selecting Clear Colors. At this point, the part should be oriented as you it would be in the lathe.
center|350px	
The lathe will operate in a 2D coordinate system, where D is the diameter or Y axis and the Length is the X axis. So, we need to create a 2D turn profile from the 3D part. Select the tab and click Turn Profile. This will open a dialog box, select the spin computation method and reduce the tessellation tolerance to 0.01.
==Setting Up the Stock==
{|width=”10%” border="1"
|-
! Image !! Step
|- align="left"
| ||
In the Toolpaths Manager, expand the properties group and click stock setup to open the Stock Setup tab. In the stock section, select Left Spindle. Open the properties and choose Cylinder from the geometry tab. This will allow you to enter the stock dimensions to be turned. The stock length should be about 30% in the chuck, so take that into consideration when choosing a stock size. On the geometry tab, you can select the Preview Lathe Boundaries to view the outline of the stock. Press enter and OK to accept the lathe stock setup settings.
|-
! Image !! Step
|- align="left"
| ||
In the chuck jaws section, select Left Spindle and click Properties. Set your grip length to however far the stock will be placed in the jaws of the chuck. At this point, the part is ready for tool paths to be created.
Mastercam Lathe Threading Operations

Typically, threading toolpaths are the last toolpaths added to a part due to the increased need for accuracy. Here we will explain how to add an OD thread. Expand the General gallery and select thread from the list. Return to the toolpaths parameter tab and select the proper threading cutter. Typically, threads will be cut at a much lower spindle rpm than most other passes of the same diameter. 
Image	Step
 	
With the threading dialog box open, click on the Thread shape parameters tab to apply the dimensions of the threads you desire to be cut. The lead value for the thread can be set here numerically. The next step is to define the thread’s outer diameter by clicking the Major Diameter button.
 	
 From here, you will be able to select the threads largest diameter in the graphics window. Repeat the process for the Minor Diameter parameter. You can also manually enter the inner and outer diameters for the thread. Again, repeat the process for the Start Position and the End Postion. This will fully define how the CNC lathe will cut the desired thread. Make sure that the thread orientation is OD to cut the outside of the part. You can click the Draw Thread button to view the thread’s geometry in the graphics window.
 	
 Click OK to create the toolpath and then continue to verify it. Make sure that the Thread operation is selected in the Toolpaths manager. Click the Verify selected operations button in the tool bar and the Mastercam Simulator window will open. Click the play button to watch how the thread will be cut by the CNC Lathe.
 	
It is usually a good idea to click the True Thread button before finishing the thread toolpath. This will create a helical geometry preview on the part instead of the default geometry created with circles and grooves. True thread is a bit slower, but much more accurate. You will have to re-verify the toolpath once more.
