Cemented Carbide Angled Radius Radius Cutter with Continuously Curved Crest Angle and Helical Edge Design

摘要

A corner radius end mill includes a tooth adjacent a helically extending flute. The tooth includes axial and radial relief surfaces connected by a corner relief surface, as well as rake surface having a rake ridge. The rake ridge is continuously curved from a bisector line until at least an axial location rearward of the corner relief surface.
