The simulation of cutting force and temperature field in turning of inconel 718

Finite element method (FEM) is a powerful tool to predict cutting process variables such as temperature field which are difficult to be obtained from experimental methods. The turning process of Inconel 718 is simulated by AdvantEdge which is professional metal-cutting processing finite element software. The effects of cutting speed, feed and cutting depth on cutting force and temperature field are analyzed. The results show that cutting forces decrease with cutting speed increasing, and increase with feed and cutting depth, and the influence of cutting depth on cutting forces is significant. The maximum temperature in the cutting zone located on the rake face at a distance of about 0.01 mm from the tool tip. As cutting speed and feed increase, the maximum temperature in the cutting area increases. The influence of cutting speed on cutting temperature is significant, but the cutting depth has little impact on temperature.
