| 摘 要： | 以CFRP复合构件为研究对象,采用横刃减小的成形刀片对复合构件孔内定心齿槽进行加工试验,分析刀片横刃大小与走刀路径对切削力的影响规律。结果表明:刀片横刃的减小有利于切削力的降低,但横刃减小到0.5 mm时,切削力减小的趋势变缓;采用横刃为0.5 mm的刀片沿着齿槽轮廓一次进给完成齿槽加工的走刀方式,其单齿加工时间较短、切削力较小、加工质量较好,该种齿槽加工方案较为合理。

| Abstract: | The carbon fiber-reinforced plastics composite components were taken as research object, the experiments of the centring-slots in a hole were carried out by the forming cutters with reduced chisel edge.The effects of the chisel edge size and of the moving route of the cutter on the cutting forces were investigated.The results show that when the chisel edge of the cutters reduces, the cutting forces tends to decrease,but the trend of the degression of the cutting forces become slow when the chisel edge is reduced to 0.5 mm.The processing scheme is of short single tooth processing time,low cutting forces, and excellent processing quality,which is one time feeding to finish a slot using the forming cutters with 0.5 mm chisel edge. It is a reasonable processing scheme. |
