Use the Gouge avoidance page to determine what happens to the toolpath when a surface prevents profiling at the lowest position.
Gouge check — Select this option so PartMaker checks the toolpath to see if any part of it gouges or deselect to turn gouge checking off.
Strategy —Select a strategy to determine how the toolpath behaves when another surface would cause gouging.
Degouge tolerance — Enter the maximum distance, normal to the surface, that the toolpath can move to find a safe position. If gouges greater than this value are detected, then the tool is lifted axially to avoid the gouge.
