摘要
以车削曲轴非圆截面零件为例,提出一种刀具非圆切削速度模型。基于PC机和PMAC运动控制卡开发非圆截面数控车削系统。在x方向加装直线进给系统,实现刀具的高速往复运动。通过分析截面轮廓信息、x轴进给部件跟随主轴圆光栅反馈角度信号运动,以确定刀具运动轨迹。该车削数控系统在汽车非圆曲轴加工生产线上投入应用,极大地提高了生产效率。
Taking the crank non-circular section turning as an example,a tool velocity model was presented.Based on PC and PMAC,an non-circular section CNC turning system was developed.High-speed reciprocating motion was achieved by installing linear feed systems in x direction.By analyzing the section profile information,x-axis feeding components moved following the feedback angle signal of the spindle circle grating to determine the tool track.The turning CNC system has been applied in the non-circular section crankshaft production line and the productivity is greatly increased.
