摘要
碳纤维增强复合材料(CFRP)为难加工材料。通过改变加工工艺参数,使用PCD成型铣刀,研究碳纤维复合材料成型槽铣削时铣削力随铣削速度和进给速度的变化关系,并分析铣削出口表面的加工缺陷及其与铣削速度的变化关系。试验结果表明,铣削力随铣削速度的升高而降低,随进给量的增大而减小;铣削出口表面主要缺陷为撕裂、毛刺和材料未切除等;其中低切削速度时主要缺陷为大面积撕裂,中等切削速度时主要缺陷为小面积撕裂及毛刺,高切削速度时为材料未切除。
CFRP is a typically hard machining material. This paper mainly focus on discussing the relationship between the cutting force and the cutting parameter, analyzing the exit surface quality regarding the cutring speed by using the forming tool of PCD with the different technological parameters. The results have shown that the cutting force was high with either a low cutting speed or a high feeding speed; the fault of the exit surface was mainly delamination, burr and non-cutting off materials; with a low cutting speed, the mainly flaw of exit surface is large area delamination, with a moderate cutting speed, the mainly flaw of exit surface is small area delamination and with a high cutting speed, the mainly flaw of exit surface is non-cutring off materials.
