摘要：在深孔钻削加工42CrMo合金钢时，易造成切削温度高、刀具磨损快等问题，从而影响加工质量。针对某传动轴的深孔加工，为得到合适的切削参数、保证技术要求，利用DEFORM3D有限元分析软件设计正交仿真试验，分析不同切削参数对切削温度和刀具磨损的影响，得到最佳的切削用量。加工结果表明，枪钻用此切削用量进行深孔加工可以满足技术要求，为优化枪钻加工42CrMo合金钢时的切削用量、提高产品质量和降低刀具磨损提供了指导。

Abstract:When deep hole drilling is performed in 42CrMo alloy steel，the problems such as high cutting temperature，rapid tool wear and the like may occur，which affecting the machining quality.For deep hole machining of a drive shaft，the technical requirements are ensured to obtain suitable cutting parameters.Using DEFORM3D finite element analysis software，an orthogonal simulation test is designed to analyze the effect of different cutting parameters on the cutting temperature and tool wear to obtain the best cutting amount.The actual processing results show that the gun drill with this cutting amount for deep hole machining can meet the technical requirements.This study provides some guidance and reference for optimizing the cutting amount of 42CrMo alloy steel used in gun drilling，improving product quality and reducing tool wear.
