300M超高强度钢高速切削过程仿真研究
Finite Element Simulation of High Speed Cutting Processing of 300M Ultra-high Strength Steel
摘要
Abstract
Aiming at the poor machinability of 300M ultra-high strength steel,the high speed cutting process of 300M ultra-high strength steel was studied by using finite element method.The cutting simulation model was established on the basis of the relevant experimental data.The chip deformation and the stress distribution of cutting area in cutting process were studied.The effects of the cutting speed and tool geometry on the cutting force and cutting temperature were also studied.The simulation results showed that the change trend of the simulation data were basically the same as the experimental data.The cutting temperature increased and the cutting force decreased following increased with the increasing of cutting speed.When the tool rake angle increased,both the cutting force and the cutting temperature decreased to a great extent and the maximum stress focused on the tip and the rake face.Both the cutting force and the cutting temperature slightly decreased when the tool back angle increased,but the extent of change was very small.关键词
