Investigations on the Effects of Different Tool Edge Geometries in the Finite Element Simulation of Machining

Abstract

This work focuses on the effects of cutting edge geometries on dead metal zone formation, as well as stress and temperature distributions in orthogonal cutting of P20 material using finite element method (FEM)

Numerical analysis of the formation of the dead metal zone with different tools in orthogonal cutting

“…Plane strain and steady-state continuous chip formation are both assumed. This model is improved by Wan et al [19] and adopted in this paper which can be seen in Fig. 3.…”

Temperature at the Tool-Chip Interface in Cryogenic and Dry Turning of AISI 4340 Using Carbide Tool

“…Bad surface finish in the dry cutting is most probably due to the adhesive effects at the workpiece-tool interface caused by the high temperature [5]. Besides, the phenomenon of flank build-up, built-up edge, or even a dead metal zone that usually forms at the edge of the radius of the insert [25], which are commonly associated with high cutting temperatures, might also contribute to the high surface roughness. The application of the LN which effectively reduced the cutting temperature, lessened all the effects mentioned above.…”

Ultra-Precision Machining of a Large Amplitude Sinusoidal Ring Surface Based on a Slow Tool Servo

“…Thus, cutting tool geometry must be optimized according to practical cutting conditions. [22]. The cutting tool radius selection of the diamond tool is presented in Fig.…”
