Corner rounding and relief

How it works

Rounding turns the path on an arc and makes ring links tangent, leaving the finished wall unchanged. Relief cuts extra material at an inside corner: with none, the cutter's radius stays in the corner; dogbone dips down the corner's diagonal; T-bone runs into one of the two walls.

The Corners group can round outside contour corners and clean reachable wall corners. Corner relief deliberately removes extra material at inside corners so a square mating part can seat. For the separate ring-to-ring transition control, see Linking clearing passes.

Where it applies

Operation	Where to find it
Pocket	Corners on supported non-trochoidal patterns
Surface clean	Corners where its clearing controls apply
3D surface rough	Corners where its clearing controls apply
Inside edge route	Corners
Outside edge route	Corners

Settings

Setting	Description
Round outside corners	Rounds eligible external contour corners.
Clean wall corners	Removes reachable material left by rounded rings.
Corner relief	Selects None, Dogbone, T-bone, or T-bone longest edge.

Corner relief

Dogbone relief opens the corner with a smaller circular extension. T-bone options remove more material and select a wall direction; T-bone longest edge chooses the longer adjacent edge. The generator skips corners it cannot cut safely and reports a warning.

Limitations

Clearing patterns: choose the compatible contour pattern first.
Linking clearing passes: use tangent transitions between compatible rings.
Trochoidal cutting: why trochoidal pockets cannot use corner relief.
