摘　　要：通过对汽车发动机缸孔进行镗削变形仿真和镗削运动轨迹的分析,采取位置变化因子和进给量变化因子,使进给量沿加工深度逐渐变化的方法,改变相应位置的变形量,同时通过改变刀路密疏程度,修正缸体缸孔的形状,提高了缸孔尺寸、圆度和圆柱度的精度以及平台网的质量。Through boring distortion simulation and boring trajectory analysis for automobile engine piston hole, a process meth- od was presented in which position change factor and feed speed change factor were used to make the feed rate gradually decease and then increase to original value. Thus the deformation in corresponding positions of the piston bore was controlled. At the same time, the level of the toni path intensity was changed, thereby the shape was amended. So the cylinder hole size precision, the roundness and the quality of the plateau honing net vein are improved
