Title (EN) CEMENTED CARBIDE CORNER RADIUS END MILL WITH CONTINUOUSLY CURVED RAKE RIDGE AND HELICAL FLUTE DESIGN
(FR) FRAISE EN BOUT À RAYON DE BEC AU CARBURE CIMENTÉ AVEC CONCEPTION D'ARÊTE D'ANGLE D'INCLINAISON INCURVÉE EN CONTINU ET CANNELURE HÉLICOÏDALE
Abstract:
(EN) A corner radius end mill (10) includes a tooth (24) adjacent a helically extending flute (26). The tooth (24) includes axial (28A) and radial (28B) relief surfaces connected by a corner relief surface (28C), as well as rake surface (30) having a rake ridge (30C). The rake ridge (30C) is continuously curved from a bisector line (LB) until at least an axial location rearward of the corner relief surface (28C).
