Sandvik Coromant groove or slot milling: trochoidal milling

Source scope
The trochoidal milling section recommends cutter diameter maximum 70% of slot width, especially difficult materials and vibration-sensitive applications.
Implementation in Prufi
PRU-142 only runs for explicit trochoidal_slot with two selected inward-facing parallel planar walls on one valid solid. Exact distance must equal the positive plane gap; a midpoint between wall surface centroids must be outside the solid. This width screen does not prove complete tool, holder, entry or path access.
