Abstract


The high-speed machining recent decades, the rapid development of an advanced metal cutting technology . Its biggest feature is in the process of cutting the high-speed and light load . Through high- speed , small depth of cut , fast-forward to the other measures to significantly reduce processing time and improve processing efficiency . Paper combines high-speed cutting mechanism of the formation of the chip , the failure of high - speed cutting tools , tool material performance requirements of the theoretical study of the system . Key research tool geometry selection of common principles and several high-speed tool cutting performance and applies cutting range . Use four factors and three levels orthogonal experiment , carried out a systematic study of the surface roughness of the high-speed machining . Range analysis of orthogonal test data obtained in high-speed machining aluminum alloy LY12 impact of high-speed machining surface roughness factor in primary and secondary order : and cooling → ??spindle speed → feedrate → depth of cut . Single factor test the material , come to the surface roughness with the cutting parameters ( spindle speed , feed rate , axial depth of cut ) quantitative relationship between the surface roughness of the empirical formula deduced . Aids UG software as an aerospace enterprise production tank parts , for example , carried out a detailed study of high-speed machining of aluminum alloy thin-walled parts . High-speed machining process focus on the tank , high-speed cutting tool path , cutting tool selection , cutting parameter optimization . Critical dimensions and tolerances of the parts of the tank to detect , verify the correctness of the high-speed cutting process of cutting parameters , analysis of the reasons for the ultra- poor local contrast of the high - speed cutting and processing the cutting parameters and the metal removal rate , verify efficient and high-quality features of high-speed cutting .
