摘　　要：在铣削钛合金的过程中,铣削温度是影响加工质量和刀具寿命的关键因素之一。通过ABAQUS软件对钛合金铣削过程进行仿真分析,并通过钛合金铣削现场试验,对仿真温度和试验温度进行对比。结果表明:钛合金在铣削加工过程中温度最高点位置位于刀-屑接触区域,仿真温度与试验温度最大误差为4.3%,仿真模型真实可靠。采用ANOVA方差分析法分析了铣削速度、进给量、铣削深度及交互因素对钛合金铣削温度的影响,并根据钛合金铣削试验数据建立了铣削最高点温度经验公式。研究结果表明,对铣削温度的影响顺序从大到小为铣削深度、进给量、铣削速度、铣削速度和进给量的交互,通过钛合金铣削试验数据建立的铣削最高点温度经验公式最大误差为7.8%,误差在允许范围之内,证明经验公式准确。In the process of milling titanium alloy,the milling temperature is one of the key factors affecting the machining quality and tool life.The ABAQUS software is used to simulate and analyze the milling process of titanium alloy,and the simulation temperature and the experiment temperature are compared through the field test of titanium alloy milling.The results show that the highest temperature of the titanium alloy is located in the tool-chip contact area during the milling process,the maximum error between the simulation temperature and the temptemperature is 4.3%,and the simulation model is feasible and reliable.ANOVA analysis of variance was used to analyze the influence of milling speed,feed,milling depth and interaction factors on the milling temperature of titanium alloy,and an empirical formula for the highest temperature of milling was established according to the milling test data of titanium alloy.The research results show that the most significant influence on the milling temperature is the interaction of milling depth,feed,milling speed,milling speed and feed.The maximum error of the formula is 7.8%,and the error is within the allowable range,which proves that the empirical formula is accurate.
