Create Uncut Boundary

This command will create a single curve representing the uncut (non-machinable) areas of the current work step. The resulting boundary curve enables the user to create a subsequent work step for removing remains. In this curve, every uncut area is enclosed by rapid-linked closed boundaries. The curve ID is automatically created by appending the string 'rest" to the current work step's ID (work step ID = step1 ; curve ID = step1-rest).

The example below shows the verified toolpath of a simple pocketing operation. Because of the big toolradius there will be some non-machinable areas left over in the corners.

Before running a finish pass along the complete profile we want to semi-finish the corners first. Once the roughing work step is complete, we select the 'Create uncut Boundary' command and get a curve that encloses the uncut areas.

Important

Please note that in case you change some settings in the previous roughing work step, you should always recreate the boundary curve (first select the roughing work step, then the 'Create Uncut Boundary' command) to reflect any changes in the boundary profile.

Below you see the subsequent work step that finish's the corners. We selected a contouring cycle and same path curve (original pocket) as the roughing work step. The previously created boundary curve was selected as Check Curve in the check curves table on the 3D Cycle Data dialog to restrict tool moves to the area inside the boundary profile. Additionally ramp moves were applied.
