Corner Trimming for CNC
(by Parametric Space)
Trimming inner corners of closed curves according to the diameter of the cutting tool (for CNC machines)
Support Email

This tool allows you to trim inside corners of closed curves. This is necessary when it is important to avoid rounding of inner corners after machining with a CNC router. Or when it is necessary to be able to have a tight fit of parts in inner corners.

Nod works with any type of curves. But only closed ones. The algorithm distinguishes between inner and outer contours if it is one part. And it's also possible to apply to a finished object layout for cutting (even when there are object attachments to the object).

The input is the diameter of the cutter and the range of internal angles to which the action will be applied.
The optimal range of angles is important for an acceptable result (e.g. no artifacts, no stray curves...). And it depends on several factors: cutter diameter, type and geometry of the input curves. 
The output gives the user a list of internal curves, a list of external curves, and a list of objects to be cut.
