摘要
为提高加工精度,对立铣刀的应力场进行了有限元分析。通过铣削力试验,对不同切削参数下立铣刀的铣削力进行动态采集,利用UG中的建模模块进行立铣刀实体建模,根据切削力实验结果给出了边界条件,在立铣刀有限元模型上进行加载,利用UG有限元分析模块,获得了立铣刀切削过程中切入、切出的瞬时应力场云图,显示了切削中铣刀片应力场的变化规律。
The paper presents the finite element analysis of the stress-field of end milling. The practices consist of the collection of the milling force of end milling under different cutting parameter by Dynamic Data Collection System and according to the experiment of milling force ,the construction of the model of end milling by the modeling module in UG ,the realization of the border condition based on the experiment result of milling force,the exertion of load on the model of finite element of end milling,and the completion of end milling instantaneous stress-field nephogram of cut-in and cut out in cutting process by the structures module in UG,which shows the change rule of the stress-field of end milling in cutting.
