摘要
采用理论分析与有限元仿真分析相结合的方法,研究得出切削线速度与切削深度对切削力、切削温度的影响以及影响刀具磨损的主要参数为刀齿切削时的最大切削层厚度。在此基础上,提出了铣削加工钛合金飞机结构件的变进给切削加工方法,并通过实验证明与传统加工方法相比,减小了刀具磨损、提高了表面加工质量,并且能提升加工效率25%左右。
Use a hybird method that combines theoretical analysis and simulation analysis. The conclusion is,apart from the cutting line speed,cutting temperature and cutting tool wear,the most significant parameter involved in the cutting process is the max thickness of cutting layer. In addition,being proofed by experiments,a new vari-speed milling method used on alloy aircraft structures is devised. Compared to traditional processing method,the new method can reduce cutting tool wear,improve quality of the machined surface,and increase processing efficiency around 25%.
