Rest machining

How it works

Large-tool roughing

Smaller-tool follow-up, limited by Regions

Rest machining is a workflow: rough the pocket with a larger tool first, then make a second rough operation with a smaller tool. Apply Regions to that second operation so it cuts only the areas the larger tool could not reach, instead of cutting the whole pocket again.

You can draw those Regions yourself when you know exactly which areas need the smaller tool. For a compatible Pocket or edge-route source operation, Create rest operation can derive the leftover areas automatically. It creates rest-region features and a related follow-up operation; choose the smaller tool and review it before generating the path.

Where it applies

Workflow	Where to find it
Automatic rest regions from Pocket	What it cuts > Rest machining
Automatic rest regions from inside or outside edge route	What it cuts > Rest machining
Manually created Regions	Limit a compatible 2.5D or 3D follow-up operation in What it cuts

Settings

The generated rest operation inherits compatible settings and targets, includes the new rest regions, and starts without a selected tool. Select the smaller tool and review all inherited depth and feed settings before generating it. The same region-limited approach works for compatible 2.5D and 3D operations: the region defines where the follow-up cuts; the selected operation and tool define how it cuts there.

Limitations

Trochoidal edge routes cannot create a rest operation

A trochoidal edge route has no area leftover that the rest-region generator can derive. A trochoidal pocket is supported because its channel width provides that information.
