切削力是导致刀具磨损以及被加工工件变形的重要因素,切削用量值是影响切削力大小的主要原因;合理的切削用量对减小加工变形、提高生产效率具有重要意义。利用正交试验设计方法,对铝合金高速铣削切削用量进行实验方案设计,并通过实际切削实验分析不同切削参数的选择对切削力大小的影响,优化切削参数的选择;其分析结果为铝合金高速铣削切削用量的选择提供参考。

The cutting force is an important factor of the tool wear and the deformation of processed parts and the cut- ting parameters is the main factor of the influence on the cutting force. Therefore, the suitable cutting parameter is of great significance to reduce the machining deformation and improve the production efficiency. First, the design method of the or- thogonal test is used to make the design of the experimental scheme of the cutting parameters of aluminum alloy high - speed milling. Then, the influence on the selection of different cutting parameters on cutting force sizes is analyzed through the actual cutting experiments in order to optimize the choice of cutting parameters. The analysis results provide a refer- ence for the choice of cutting parameters of aluminum alloy high - speed milling.
