摘要：为更好地预测机加工中的切削力及切削温度，利用AdvantEdge软件对AerMet100超高强度钢的拉削工艺进行仿真研究，通过单因素试验法分析了不同切削参数对切削力及切削温度的影响规律。采用多元线性回归分析法对正交仿真试验数据进行分析，建立切削力及切削温度的模型公式，并利用极差分析法筛选出最优组合，对模型进行验证。结果表明：齿升量是影响切削力的主要因素，切削速度和拉刀前角次之；齿升量和切削速度也是影响切削温度的主要因素，拉刀后角对切削力及切削温度的影响较小，且建立的模型公式能较好地预测切削力及切削温度。

Abstract:In order to predict machining of cutting force and cutting temperature preferably，by using AdvantEdge software for AerMet100 ultrahigh strength steel broaching process simulation，through single factor experiment method，the different cutting parameters on cutting force and cutting temperature are analyzed.Multiple linear regression analysis is used to analysis the orthogonal simulation test data，and the model formulas of cutting force and cutting temperature are established，the optimal combination is selected by range analysis method and the model is verified.The results show that the tooth lift is the main factor affecting the cutting force，the cutting speed and the broach rake angle are the second.Tooth lift and cutting speed are also the main factors affecting the cutting temperature.The relief angle of broach has little influence on the cutting force and cutting temperature，and the established model formula can predict cutting force and cutting temperature much better.
