摘要：

为深入了解工艺参数对波动加工轨迹驱动的板料锤击渐进成形时间的影响规律，选择工具直径、工具进给速度、垂直层进给量、波长以及振幅等5个工艺参数为因素，以成形阶梯型锥杯时间为指标，进行正交实验，并对实验结果进行极差分析和方差分析。研究结果表明：垂直层进给量对成形时间有显著影响，而其他4个工艺参数的影响不显著；成形时间随工具垂直层进给量、工具进给速度、波长和工具直径的增加而减少，随振幅的增加而增加。研究结果为合理选择工艺参数、减少波动加工轨迹驱动的板料锤击渐进成形时间提供了理论依据。

In order to further understand the influences of main forming parameters on the forming time in incremental punching sheet driven by wave tool path, five forming parameters of tool diameter, tool feed rate,vertical layer feed, wave length and amplitude were selected as factors, and the forming time of a stepped cone cup was selected as indicator. Then, the orthogonal experiments were conducted, and the experimental results were analyzed by range analysis and variance analysis. The results show that the tool vertical layer feed significantly affects the forming time, while other four parameters have no significant effect. In addition, the forming time decreases with the increasing of tool vertical layer feed, tool feed rate, wave length and tool diameter, but increases with the increasing of amplitude. The completed work provides a theoretical basis for rational selection of forming parameters to reduce forming time in incremental punching sheet driven by wave tool path.
