    摘要:

    针对碳纤维复合材料(CFRP)的齿槽加工,提出采用T型铣刀切制齿槽。以平纹CFRP为研究对象,通过齿槽的切削试验,分析切削力和残余因子。试验表明:切削力随着切削速度vc的增大而减小,但切削速度vc大于245 m/min时,进给方向切削力Fx将逐渐增大;与切削速度vc相比,进给速度vf对残余因子Fb的影响更大,随着它的增大,残余因子Fb平均减小46.63%;顺铣时的切削力和残余因子比逆铣时的明显要小。研究结果为CFRP的齿槽铣削加工提供了技术指导。

    Abstract:

    The T-slot milling cutters were proposed to use for the cutting of slots by aimed at the Carbon Fiber-reinforced Composites (CFRP). The slots milling testes of plain woven CFRP were done as a study object. The milling forces and the residual factor were analyzed. The experimental results show that the all cutting forces will decrease with the increased cutting speed vc, but cutting force Fx will increase gradually in feeding direction, when the cutting speed vc is more than 245 m/min. The residual factor Fb will be influenced greater by the feed speed vf as compared with the cutting speed vc. The residual factor Fb will decrease in average by 46.63%, with the increasing of the feed speed vf. The all cutting forces and the residual factor from up-milling are much smaller than ones form down-milling. The study results provide some technical guidance for the slots milling on CFRP.
