随着航空航天的数字化的快速发展,以框梁类为主的机体零件的架构更加复杂,且数控加工已经成为飞机整体机构的主要成形方法。数控加工零件的材料去除率增高,零件加工和装夹基准更复杂,统一零件工艺凸台方案设计将成为提高零件数控加工稳定性、标准化和加工效率的重要因素。总结现有加工工艺凸台设计的缺点和现状,从零件加工的准备时间、加工刚性、加工难度、刀具性能、常规去凸台等方面进行标准化研究,规范了工艺凸台的方案设计,并在大量零件的实际加工运用中取得显著的成效。
With the rapid development of digitalization in aerospace, the structure of body parts mainly including frame and beam is more complicated, and the numerical control processing has become the main forming method of the entire aircraft body. Increasing the material removal rate of CNC machining parts, machining parts and clamping more complex benchmarks, unified parts process boss program design will become part CNC parts to improve the stability, standardization and processing efficiency of the important factors. Summarize the shortcomings and current situation of the design of the existing processing technology boss, standardize the preparation process from the part preparation, processing rigidity, processing difficulty, tool performance, conventional to the boss, etc., standardize the program design of the process boss, and in A large number of parts of the actual processing and use achieved remarkable results.
