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.
