摘要
在干切条件下研究了端面车削玻璃纤维增强复合材料薄壁筒时切削力的变化特点,分析切削速度、进给量、切削深度、刀尖圆弧半径、进给方式对切削力的影响规律。试验结果表明:纵向进给方式和横向进给方式下,切削力变化特点不同;在横向进给方式下,切削力随进给量、切削深度的增大而增大,随切削速度的增大先减小后增大;以横向进给方式车削端面时,刀尖圆弧与工件的接触状态直接影响切削力的变化;以纵向进给方式车削玻璃纤维增强复合材料薄壁筒端面时,切削力随着进给量的增大而增大。
Under dry cutting conditions,the variation characteristics of cutting force when end-face turning glass fiber rein forced composite thin-wall cylinder are studied,as well as the influence of cutting speed,feed rate,depth of cut,tool tip radius and feed mode on the cutting force.Experimental results show that the variation characteristics of cutting force under longitudinal feed mode and transverse feed mode are different.Under the lateral feed mode,the cutting force increases with the increase of feed rate and depth of cut,and decreases first and then increases with the increase of cutting speed.When turning the end face with lateral feed,the contact state between the tool tip radius and the workpiece directly affects the variation of cutting force.When turning the thin-walled end face of glass fiber reinforced composite materials using longitudinal feed,the cutting force increases with the increase of feed rate.
