摘　　要：为优化Ti40阻燃钛合金铣削工艺,采用最佳铣削温度原理对铣削参数进行了试验研究。首先采用正交试验,通过回归分析建立了铣削温度和参数之间的经验公式,分析了铣削用量中,各参数对铣削温度的影响程度大小;后采用单因素刀具磨损对比试验方法,确定最佳铣削温度值,并进一步计算得到最佳铣削温度下切削用量经验公式,并通过试验进行了验证;最后,对不同铣削温度下的表面粗糙度进行了试验对比分析。结果表明:铣削Ti40阻燃钛合金工件的最佳铣削温度为437℃左右;经切削试验验证,基于最佳铣削温度优化出的铣削用量与刀具磨损结果是一致的,同时,经测量对比,最佳铣削温度下铣削加工可以获得较好的表面粗糙度,均表明采用最佳铣削温度优化切削工艺的方法是可靠的。In order to optimize the milling technology of Ti40 burn resistant titanium alloy,experimental study on milling parameters is carried out based on the principle of optimal cutting temperature.Firstly,the orthogonal experiment is carried out to build the empirical formula for milling temperature and parameters through regression analysis,and the effect of each parameter on milling temperature is analyzed.Secondly,the single factor experiment is conducted to determine the optimal cutting temperature value.Also,the empirical formula for the optimal milling temperature and milling parameters is obtained and validated with experiments.Finally,comparison analysis of the surface roughness under different milling temperature is completed.It is shown that the optimal milling temperature of Ti40 burn resistant titanium alloy is around 437℃,tool wear results is consistent with the optimal parameters,and better surface roughness with the optimal parameters can be acquired than common parameters.This investigation shows that it is reliable to optimize the cutting technology using the principle of the optimal temperature.
