摘要
切削参数优化能够有效地提高工件的加工效率,降低加工成本。然而,当理论模型不准确或者工件产生较大变形时,以理论模型为基础的离线优化方法不再实用,而在线优化方法对设备性能要求较高,很难进行普遍使用。针对铣削加工工艺参数优化问题,提出一种基于在线测量切削力信号的进给速度优化方法,首先分析了铣削力解析模型,建立了进给速度优化数学模型,然后根据刀具参数和机床参数确定了优化约束条件,最后设计了实验模型,通过实际的加工实验验证了本文提出的进给速度优化方法。
Optimization of cutting parameters can effectively improve machining efficiency and reduce machining cost.However,the theoretical model based off-line optimization method is no longer effective when the model is inaccurate or the parts deformed greatly.At the same time,the online optimization method has a highly demand on the performance of the equipment and is difficult to be widely used.Aiming at the optimization of milling process parameters,a feed-rate optimization method based on online measurement of cutting force signal is proposed.Firstly,the analytical model of milling force is analyzed and the mathematical model of feed-rate optimization is established.Then the constraints are determined according to the performance of the cutter and the machine tool.Finally,an experimental model is designed and the method of feed speed optimization proposed in this paper is verified by actual machining experiments.
