残余应力作为影响高精度加工质量零件长期稳定性的主要因素，其控制方法的研究受到广泛关注。为此，本文提出了一种沿着刀具轨迹重叠率优化方法的数学模型，在粗加工时，选择较大的重叠系数K值是优化表面加工残余应力的必要条件，而在精加工时，选择较小的K值则是必不可少的。收缩重叠系数K与残余应力分布对变形影响的减小相呼应，不可避免地伴随着材料去除率的降低。在此基础上，以某航空薄壁件为例，对所提方法进行了验证。
As the main factor, residual stress undoubtedly restricts the long-term stability of high-precision machining quality parts, arresting an extensive attention on studying its control method. Therefore, a model is meticulously proposed, along with the optimization method of the overlap rate of cutting tool path. In the roughing, the selection of a larger magnitude of overlap coefficientKis found to be necessary for the optimization of the surface machined residual stress, followed by an indispensable selection of smallerKvalues in the finishing. The shrinking overlap coefficientKechoes with the decreasing influence of the deformation affected by the residual stress distribution, inevitably accompanied by the lowering material removal rate. Based on all the optimization results, an aerospace thin-walled part is adopted in the application case to verify the proposed approach.
