Pattern Tool Path Operations

With the tool paths now set up, you can use the pattern feature in the Manufacturing workspace to duplicate the operations.

New Pattern Set Up

Since each operation requires a different tool, each operation will need to be a separate pattern.

Right-click on the first operation (1/16in Adaptive Clearing) and select Add to New Pattern from the menu.

Under Direction 1, click the Edge button and select one of the edges in the model that is in the desired axis.

Under Spacing for Direction 1, type in 28.5mm.

Under Number of instances 1, type in 4.

Press OK button to accept and save.

Repeat this process for the 2D Pocket and 2D contour.

Simulate and Post Process

Reference the previous CAM setup to simulate the operations. If everything looks good, proceed to Post Process the GCode files. You have the option to select multiple operations in the Browser. For example, the Adaptive Clearing and 2D Contour operations use the same tool so this could be posted as a single GCode file.
