铣削灰铸铁HT250刀具磨损机制的有限元仿真研究
Research on Tool Wear Mechanism of Milling Gray Cast Iron HT250 Based on Finite Element Simulation
摘要
Abstract
To investigate the cutting performance and tool wear mechanism of gray cast iron HT250,a finite element model of milling gray cast iron HT250 was established using the DEFORM-3D finite element simulation software.Through the design of single factor experiment and orthogonal experiment and the analysis of the simulation cutting process,the results indicate that tool wear mainly occurs at the rake face near the cutting edge,resulting in the generation of a serrated boundary crater with a narrow width.Tool wear increases with higher cutting parameters.The feed rate has the greatest influence,followed by the cutting speed,and the cutting depth has the least influence.Therefore,on the promise of ensuring machining accuracy and performance requirements,appropriate increasing cutting depth will improve production efficiency.关键词
