Abstract

Abstract

To compare the cutting performance of different types of diamond coated tools, a variety of tools with different diamond coated materials were selected for the machining of graphite materials, and WC cemented carbide tool and TiAlN coated tools were used for comparison.The cutting life, coating morphology, surface quality and cutting force of different diamond coated tools were analyzed.The results show that the coating morphologies of diamond coated tools are mainly nanocrystalline and microcrystalline.The cutting life of diamond coated tools is more than ten times that of cemented carbide and TiAlN coated tools.The cutting life of several different types of diamond coated tools has little difference.However, the refinement of diamond coated surface grains can reduce surface roughness and the cutting force.Coating falling off is the main wear form of diamond tools.
