| Abstract: | Cutting force and cutting heat are two important factors influencing tool life and machined surface quality in thread milling process, and the rake angle of the tool has a great impact on metal cutting process of chip formation, cutting force and cutting temperature. Therefore, the choice of a reasonable rake angle is essential for improving tool life and thread machining efficiency. First, a metal cutting finite element software AdvantEdge is used to simulate the thread milling on steel 45 #, to obtain the relationship of cutting force and cutting temperature with time. Then, comparative analysis of effect of different rake angles on cutting force and cutting temperature is conducted, and the optimal rake angle for the milling cutter is selected. The analysis results provide a reference for the choice of rake angle of a thread milling cutter. |
