Rest Roughing a 2D Offset Roughing reference

The purpose of Rest Machining is to remove the remaining stock from a previously cut part. It is designed to "get the rest" of the stock. Simply enable the Rest Machining checkbox on the Geometry tab, and enter the tool diameter and the tool corner radius that was previously used on the geometry.

For example, if you start roughing with a 20 mm tool that does not fit in all areas of a given pocket, then make another 2D Offset Roughing operation with a smaller tool, and specify 20 mm for the Rest Machining - Tool Diameter parameter.

The resulting toolpaths:

2D Offset Roughing with 20 mm tool

2D Offset Roughing with 10 mm tool and Rest Machining enabled
