In SolidCAM you can define separate offsets on the wall, the floor and the islands of the pocket.
Set all offset values to 0.2 mm.

You can also specify whether you would like to actually leave each offset on the CAM-Part, or if you want to remove it up to the original contour with one last finishing cut.
Select the Wall+Floor option from the list in the Finish area to remove the remaining offsets with the last cut.

Generate the tool path with the Save & Calculate button.

Click on the Exit button to close the Pocket Operation dialog box after SolidCAM has completed the calculation.
