Degouge tolerance

It defines the upper acceptable bound for this intermediate form of gouge avoidance. If gouges greater than this value are detected then the tool is lifted axially to avoid the gouge.

This value can therefore be used to control the location and amount of material left on non-swarfable surfaces. For example, if material on a surface can mostly be machined by swarf machining, but there is a region where 3 mm of material could be left, then you can either:

• choose a Radial offset of 3 mm to leave 3 mm of material on the whole of the surface; or
• set a Radial offset of 0 mm and a Degouge tolerance of 3 mm. In this case, the surface is completely machined where possible, but some material of up to 3 mm is left on a part of the surface.

Note: Degouge tolerance remains in effect even if Gouge check is not selected.
