面向铜镍合金车削加工的微织构CBN刀具研究
Research on Micro-Textured CBN Tools for Turning of Copper-Nickel Alloy
摘要
Abstract
Three types of micro-textures,including broken line grooves,longitudinal grooves and 45° oblique grooves,were constructed on the tool surface and the influence of the tool surface micro-texture on the tool cutting performance during copper-nickel alloy cutting was deeply studied;by controlling a single-variable method,the influence of texture width,texture depth,texture spacing and cutting edge margin on the cutting performance was analyzed,the optimal texture parameter range of the longitudinal groove micro-texture was determined,and the optimal texture parameters were determined through orthogonal experiments.The results show that compared with the non-textured tool,the longitudinal groove micro-textured tool can effectively reduce the main cutting force and cutting temperature;the optimal texture width is 85 µm,the texture spacing is 40 µm,the texture depth is 30 µm,and the cutting edge margin is 40 µm;when the optimal micro-textured tool is used to process copper-nickel alloy,the average main cutting force is reduced by 23.07%,the average value of the maximum cutting temperature is reduced by 22.46%,and the average equivalent stress is reduced by 19.53%,indicating that the residual stress of the workpiece can be effectively reduced and the cutting performance can be improved.关键词
