Cutting Performance of Diamond Coated, TiAlN Coated and Carbide Cutting Tools in High Speed Milling Graphite

Abstract

This paper focusing on cutting performance high speed milling Electrical Discharging Machining (EDM) graphite with diamond coated、Carbide (WC) and TiAlN coated cutting Tools. tools wear, cutting force and machined surface had been researched. Experiment study including cutting speed, feed rate per tooth, radial depth of cut, axial depth of cut, and material of tools factors effects on the cutting forces. Cutting parameters are optimized based on the orthogonal experiment. Experiment in high speed milling with diamond coated tools all comparison with TiAlN coated and Carbide (WC) tools. On the surface quality, cutting forces and tool wear influence graphite cutting tool materials research, process parameters, tool design and optimization of processing parameters to provide supportive data. The minimum cutting force as the goal, through the orthogonal experiment for the optimization of cutting parameters obtained for the high speed milling graphite with diamond-coated tool: cutting force 360m/min,feed per tooth 0.15mm/z, radial depth of cut 0.9mm, axial depth of 9mm.
