Definition

The cutting edge geometry is the geometry of the cutting wedge in the orthogonal cut of the tool. It has to be divided in the cutting edge micro geometry and macro geometry. The macro geometry is described by the rake, clearance, and wedge angle. The micro geometry is described by the cutting edge rounding and the chamfer geometry. The cutting edge geometry has a big influence on the machining forces, the chip formation, and the tool wear.

Theory and Application

Introduction

Besides the process parameters and tool coatings, the cutting edge geometry shows a major impact on the chip formation, machining forces, and tool wear. The right choice of the cutting edge geometry enables a higher productivity, workpiece quality, and a reduced tool wear (Byrne et al. 2003). The cutting edge geometry is the geometry of the cutting wedge in the orthogonal cut (ISO 3002-1 1982). The cutting...
