插铣是一种高效的开腔加工方法,采用插铣加工34CrNi3Mo高强度合金钢时,因材料强度高、硬度大等特性导致切削温度较高,使得刀具寿命和加工表面质量降低,加工难度增大.为了研究切削参数对切削温度的影响,建立了插铣34CrNi3Mo高强度钢的切削仿真模型,通过正交仿真试验研究了切削速度、每齿进给量和切削宽度对切削温度的影响规律.建立了切削温度的经验公式,并运用极差分析和方差分析获得了可有效降低切削温度的最优切削参数.结果表明:通过增加每齿进给量提高插铣加工高强度钢的切削效率,有利于降低切削温度.
Research on Cutting Temperature in Machining 34CrNi3Mo High Strength Steel by Plunge Milling
Insertion milling is an efficient open cavity processing method.It is used to mill 34CrNi3Mo high-strength alloy steel.Because of its high strength,hardness and other characteristics,the cutting temperature is higher,which reduces the tool life and machining surface quality,and improves the processing difficulty.In order to study the effect of cutting pa-rameters on cutting temperature,the cutting simulation model for plunge milling 34CrNi3Mo high strength steel is estab-lished.The influence of cutting speed,feed rate per tooth,and cutting width on cutting temperature is studied through or-thogonal simulation experiments.An empirical formula for cutting temperature is established,and the optimal cutting param-eters that can effectively reduce cutting temperature are obtained using range analysis and variance analysis.The results in-dicate that increasing the feed rate per tooth can improve the cutting efficiency of milling high-strength steel,which is bene-ficial for reducing the cutting temperature.
