【摘要】：綜合零件的加工特征及約束條件并引入布爾差運(yùn)算,可以分解出零件典型面組并生成對應(yīng)的工藝路線譜系,達(dá)到零件加工工藝快速優(yōu)化設(shè)計(jì)的目的。通過分析三維工序模型典型面組加工時的動態(tài)特性,采用B樣條曲線插值參數(shù)化的方法構(gòu)建刀具-工件接觸區(qū)域動態(tài)邊界的統(tǒng)一數(shù)學(xué)模型,預(yù)測切削載荷動態(tài)變化狀況,并進(jìn)行切削參數(shù)優(yōu)化達(dá)到有效控制切削載荷的目的。最后以某零件的車削加工為例進(jìn)行分析,驗(yàn)證該工藝優(yōu)化策略的可行性。
[Abstract]:By synthesizing the machining characteristics and constraints of the parts and introducing Boolean difference operation, the typical surface group of the parts can be decomposed and the corresponding process route pedigree can be generated, which can achieve the purpose of rapid optimization design of the machining process of the parts. By analyzing the dynamic characteristics of 3D process model in typical surface group machining, a unified mathematical model of the dynamic boundary of cutter workpiece contact region is constructed by using B-spline curve interpolation parameterization method, and the dynamic change of cutting load is predicted. The cutting parameters are optimized to effectively control the cutting load. Finally, an example is given to verify the feasibility of the process optimization strategy.
