Research On Tool’s Wear Based On Variety Workpiece Material And Different Cutting Tool

Research on cutting process is significantly important for the development andimprovement of cutting technology, since, in the metal cutting process, some physicalphenomena, such as cutting force, cutting temperature, cutting tool wear, damage andsurface integrity are all based on cutting deformation. While, metal cutting process is themost basic, most widely employed and most important processing technology in theindustrial production.Cutting force and cutting temperature are the most important physical parameters inthe cutting process. They directly affect the generation of cutting heat, and furtherinfluence the tool wear, tool life, processing precision and product surface quality,relatesto the growth and disappearance of bue. Surface roughness of workpiece is an importantparameter, which would affect the contact area between the elements. Big roughness willreduce the contact stiffness and coordination precision of the two contacting surfaces.Cutting tool is directly involved in the cutting process, therefore, wear and damage of thecutting tool will inevitably occur during the cutting process, which will further reduce themachining precision, and induce greater surface roughness and surface qualitydeterioration.In this study, different milling processes was employed to process different toolmaterials, and the cutting force, cutting temperature, surface roughness, and the tool wearand cutting life related to the milling process were further investigated as well.Content of this study are as follows:First, by means of milling experiments, comprehensive studies of cutting force,cutting temperature, surface roughness, tool wear and tool life were performed. Based onthis part of study, optimizations of milling tool material milling parameters are possible.Second, to analysis the main factors which induced the cutting temperature changes,based on verification with the experimental data. Based on this part of study, measuresthat could control the milling temperature are suggested.Third, measured the surface roughness of the product, and obtained the optimizedcutting tool materials and processing parameters to achieve certain roughness. Last of all, based on milling test, investigated the wearing modes of different cuttingtools during hard-to-cut-material processing, analyzed the mechanism, and compared themilling tool life. Optimized tool materials are suggested.
