Setup Sheet:

NOTE: In order to machine this part we will have 2 setups and output 2 NC files.


CREATING AND RENAMING TOOLPATH GROUPS TUTORIAL #31

STEP 22: CREATING AND RENAMING TOOLPATH GROUPS

To machine the part in two different setups, we will need to have two separate programs. To be able

to post process separately the operations of each setup, we will create them under different toolpath

groups with different NC names.

22.1 Rename the current Toolpath Group - 1 and NC file

Click two times on the Toolpath Group - 1 to highlight it and rename it "Setup #1."

Figure: 22.1.1

Right mouse click on the toolpath group and select Edit selected operations and then, select

Change NC file name.

Figure: 22.1.2

Enter the new NC name: Setup #1.

Figure: 22.1.3


TUTORIAL #31 CONTOUR TOOLPATH

Select the OK button to accept the new NC name.

Create a new Toolpath Group.

Right mouse click on the Setup #1 and hold the mouse button down. Drag the cursor below

the insert arrow and select Copy After. This will create a new toolpath group and copy the

toolpaths below. At this time with the toolpaths selected press delete on your keyboard. A

message will pop up asking you if you want to delete the toolpaths. Select Yes from this

message. Rename the toolpath group "Setup #2".
