Tool Structure Design Based on Thermodynamic Coupling Theory
This paper proposes a tool structure design method based on the thermal-mechanical coupling theory.Based on the simulation experiment of high-speed milling 7075 alloy steel with a carbide flat head chamfered end mill and the DE-FROM 2D/3D software,the main tool structural parameters affecting cutting force and heat,such as rake angle,rake angle,spiral angle,and number of cutting edges,are simulated and studied under the parameters of spindle rotation speed of 4000r/min,feed speed of 2000mm/min,and cutting depth of 0.1mm.The research shows that under this technological envi-ronment,when the front angle is 15°,the back angle is 10°,the spiral angle is 35°,and the number of teeth of the four edge cutting tool,the cutting force and cutting heat of the cutting tool will be better improved compared to other structural param-eters,thereby improving the tool structure design method.
