Set the rotation axis for 3+1 machining

For a 3+1 setup, tell CAM Assist which axis the part rotates around on your 4th axis. CAM Assist indexes the part to fixed positions around that axis and machines each position in 3 axis.

Before you start

• In the Setups stage, include the setup with the switch on its card and set its Mode to 3+1. Select Axis of rotation only appears for included 3+1 setups.
• Set the Rotational axis limits of your machine in My Shop > Machines. See Machine details CAM Assist needs.

Set the axis

1. On the setup card, under Select Axis of rotation, click X-Axis (default) or Y-Axis.

The axis is relative to the setup's own coordinate system, not the CAM document's. Each setup has its own rotation axis.
