摘　　要：Stellite6合金是以钴铬钨为主要元素的高温合金,红硬性好但导热性能差,在切削加工时刀具与切屑接触区域易产生较高的温度。建立Stellite6合金切削仿真模型,确定试验方法及条件,运用正交试验与仿真研究每齿进给量、切削速度和切削宽度对切削温度的影响规律,使用极差分析法和方差分析法获得铣削参数对切削温度影响的主次顺序,得到以最小切削温度为目标的最优切削参数,并建立了切削温度的经验计算公式。Stellite6 alloy is a high temperature alloy with cobalt,chromium and tungsten as the main element.It has good red hardness but poor thermal conductivity.During cutting,the contact area between the tool and the chip is easy to produce higher temperature.The cutting simulation model of Stellite6 alloy is established,and the experimental methods and conditions are determined.The influence of feed per tooth,cutting speed and cutting width on cutting temperature is studied by orthogonal test and simulation.The range analysis method and variance analysis method are used to obtain the primary and secondary order of the influence of milling parameters on cutting temperature.The optimal cutting parameters with the minimum cutting temperature as the goal are obtained,and the empirical calculation formula of cutting temperature is established.
