tooth mill meaning in English

齿式粉碎机

Machining deformation of aircraft monolithic component is simulated by finite element method ( fem ) and validated by experiment . the initial residual stress in pre - stretched plate is generated by simulating quenching and stretching processes . with a single tool - tooth milling process fem , the machining loads in monolithic component material removing is obtained . restart - calculation is put forward to complete the whole simulation of machining process . to verify the fem result , an experiment is carried out . the deformation distribution of the monolithic component resulting from fem shows a good agreement with the experiment result , which indicates that the key technologies presented in the paper are practicable and can be used to simulate the milling process of monolithic component to predict its deformation . lengthy and expensive trial and error experiment process can be avoided
在模拟淬火、拉伸过程获得含有初始残余应力的预拉伸板材以及模拟单齿切削过程获得切削载荷的基础上,提出并采用接力算法,对一航空整体结构件的材料铣削过程进行有限元仿真,同时进行了试验研究.结果表明,有限元模拟的整体结构件的变形与试验具有一致性,从而证明提出的整体结构件加工仿真关键技术的可行性,避免了为研究加工变形而进行的繁琐的试错法
