【摘要】：為避免薄壁深腔零件側(cè)壁加工過程中因銑削力引起的讓刀變形而導(dǎo)致加工精度較低的問題,提出一種基于有限元的銑削加工誤差仿真算法�？紤]工件/刀具系統(tǒng)的讓刀變形及工件的回彈變形,計(jì)算生成刀齒微元的連續(xù)運(yùn)動(dòng)軌跡,并基于點(diǎn)的六面體映射算法對(duì)材料進(jìn)行去除,從而得到連續(xù)加工過程和加工面上任意點(diǎn)的加工誤差及加工面形貌。以某典型薄壁深腔開口框體結(jié)構(gòu)為加工對(duì)象進(jìn)行了仿真分析,通過實(shí)驗(yàn)驗(yàn)證了所提仿真方法的準(zhǔn)確性。
[Abstract]:In order to avoid the problem of low machining precision caused by the cutting force caused by milling force in the machining process of thin and deep cavity parts, a simulation algorithm based on finite element method for milling machining error is proposed. The point's hexahedral mapping algorithm is used to remove the material, thus the machining error and the surface morphology of any point on the machining surface are obtained. A typical thin-walled and deep cavity opening frame structure is used to simulate the machining object. The accuracy of the proposed simulation method is verified by the experiment.
