Cutting Test Research for Coated Carbide Cutting Tools
A coated carbide cutting tool with its high hardness and high wear resistance,good chemical stability and extensive compatibility characteristics,is widely applied in the metal cutting processing field.It is one of the cutting tools,belonging to the current focus research and development project of all countries in the world.The author mainly studies the cutting force contrast between coated carbide cutting tools and not coated ones.At the same time study them on the rake face friction coefficient contrast and the chip deformation coefficient contrast so as to explain the reasons for coated cutting tool cutting force decrease.The research indicates that,in machining course,applying physical vapor deposition coated technology (PVD) of carbide cutting tools cutting force change with feeds,cutting depth and speed is the same as not coated carbide cutting tools.But coated carbide cutting tools cutting force is obviously less than that of not coated carbide cutting tools.The main reason is that the friction coefficient between the two kinds of cutting tool materials and the workpiece is different.The result of study will help popularization and application of coated carbide cutting tools.
