摘要: 铣削是复合材料最常用的机械加工形式之一。减小铣削力可以提高零件的表面质量,减少刀具的磨损等。使用硬质合金铣刀对该材料进行铣削试验,研究了铣削力的变化规律;并用Excel软件对铣削力的试验数据进行回归分析,最后建立了铣削力的经验公式。结果表明:进给速度对铣削力影响较大,铣削力随进给速度的增大而增大,基本呈线性关系;主轴转速对铣削力影响不是很大,铣削力随主轴转速的增大逐步增大。

Abstract: Carbon fiber reinforced plastics is a typical difficult-to-machine material. Milling is the most practical machining operation for machining composite materials. The decrease in milling force can improve the surface quality of the parts and reduce tool wear. The milling force has been studied with carbide mill during the milling of CFRP. The regression analysis is carried out with software Excel. At last,the empirical formulas of milling force are derived. The results show that the feed speed has great effect on the milling force. The milling force increases with the increasing of feed speed. On the other hand,the spindle speed has slight influence on the milling force,and the milling force gradually increases with the increasing of spindle speed.
