【摘要】：高速干切滾齒工藝是一種發(fā)展迅速的齒輪綠色制造工藝,但干切條件下刀具容易磨損,特別是滾切工藝材料去除過程的復(fù)雜性,導(dǎo)致切削刃的載荷分布不均,刀具局部磨損嚴(yán)重,影響該工藝的經(jīng)濟(jì)性。面向齒輪滾切工藝的材料去除過程,提出了基于三維切屑的切削刃載荷計(jì)算方法,根據(jù)不同切屑幾何獲得相應(yīng)單刃切削載荷分布狀態(tài)及批量加工中切削刃的平均載荷分布狀態(tài)。通過仿真計(jì)算和滾切試驗(yàn)案例,對(duì)比分析了切削刃載荷分布與切削刃實(shí)際磨損的關(guān)系,發(fā)現(xiàn)側(cè)刃和頂刃過度圓弧處切削載荷最大,切削刃磨損也最嚴(yán)重,驗(yàn)證了該方法的有效性。最后,基于該方法分析了滾切進(jìn)給方向和進(jìn)給量對(duì)切削刃載荷分布的影響,其結(jié)論對(duì)于生產(chǎn)實(shí)踐中控制刀具磨損具有指導(dǎo)意義。
[Abstract]:High speed dry cutting and hobbing is a rapidly developing green manufacturing process for gears. However, tool wear is easy under dry cutting conditions, especially because of the complexity of material removal process, which leads to uneven load distribution of cutting edge. The local wear of the cutting tool is serious, which affects the economy of the process. For the material removal process of gear rolling process, a method for calculating cutting edge load based on 3D chip is proposed. According to different chip geometry, the corresponding single-edge cutting load distribution state and the average load distribution state of cutting edge in batch machining are obtained. The relationship between the cutting edge load distribution and the actual wear of the cutting edge is compared and analyzed through the simulation calculation and the rolling test case. It is found that the cutting load at the edge and the top edge of the cutting edge is the largest and the cutting edge wear is the most serious. The effectiveness of the method is verified. Finally, based on this method, the influence of feed direction and feed rate on the load distribution of cutting edge is analyzed, and the conclusion is of guiding significance for controlling tool wear in production practice.
