Pencil Milling

The Pencil Milling is a 3D contouring which removes material along the bi-tangency areas, that is to say the areas with multiple contacts between the tool and the part.

Key Points

Allows material to be removed from the interior corners of a part before passing the finishing or rework tool.
This cycle is used to machine the angles in 3D contouring.
Possibility of machining going down or going up.
Possibility of using a 2T, toroidal or hemispherical cutter.

Does not manage the Down cut/Conventional cut machining mode.
Does not manage pass depth.
