摘要
针对CFRP在侧铣过程中的加工缺陷进行研究,采用斜角切削方式,基于仿真手段从切削力的角度探究纤维方向角对材料表面质量的影响.实验结果表明:纤维方向角对切削力的大小有很大影响,切削力趋势为Fx(0°)>Fx(45°)>Fx(135°)>Fx(90°);顺纤维切削的表面质量优于逆纤维切削的表面质量,且在顺纤维切削时,切削力越大,最大毛刺长度越短,表面质量越好.
Abstract
In this paper,the machining defects of CFRP in the process of side milling are studied,and the expression of bevel cutting is adopted to explore the influence of fiber direction angle on the surface quality of the material from the an-gle of cutting force by means of simulation.The experimental results show that the fiber direction angle has great influence on the cutting force,the cutting force trend is Fx(0°)>Fx(45°)>Fx(135°)>Fx(90°).The surface quality of transverse fiber cutting is better than that of inverse fiber cutting,and the greater the cutting force is,the shorter the maximum burr length is,the better the surface quality is.
