Cutting insert and cutting tool for chip removing machining

摘要: An insert (10) for a milling cutter has chip face (11) and bottom (12) which are interconnected by side surfaces. The intersection of surfaces (14-17) with the forms four cutting edges (12A-12D). Each surface is beveled at its edge to form planar clearance face, width increases toward one corners. includes main portion (17′), corner (17˝′), secondary (17˝). (17˝) extends inwardly from an associated angle no greater than degrees. At each corner, actual another ninety mounted negative radial rake positive axial such that presents workpiece effective degrees cut degree shoulder in workpiece.
