Abstract
Based on the analysis of spiral groove tap parameters,the material,heat treatment state,cutting fluid selec-tion,and tool life of the M24 spiral groove tap are studied and optimized.The heat treatment process parameters and micro-structure of M24 spiral groove tap are analyzed.Through life analysis,it is found that the cutting torque of the developed tap can reach the same level as that of the imported tap,with smooth chip removal,and the cutting condition and tool durability are basically equivalent to those of the imported tap.In this paper,the research project has been conducted to optimize the material selection,surface condition,heat treatment methods and processes,and design of tool structure parameters for spiral fluted taps.The research project has certain application value.
