Cutting simulation test is designed to take the dot-pit weaving structure carbide tool as the research object,and orthogonal test design method is adopted to determine the degree of influence of weaving structure parameters on cutting force and cutting temperature through polar analysis.The structure of the tool has a significant effect on its cutting performance,and the reasonably designed structure parameters can reduce the cutting force and cutting heat generation,thus improving the cutting performance.The results show that the optimal geometric parameters of pit configuration are 70 μm pit diameter,20 μm pit depth and 100 μm edge distance,and the influence on the main cutting force,feed force and cutting temperature of the front face is greater than the pit diameter and greater than the edge distance.
