摘　　要：针对阶梯轴的切削加工,建立了弯曲变形的力学模型,应用积分法求出变截面简支梁弯曲变形的通用表达式-变形挠曲线方程,并用于零件加工的实际计算。通过工艺参数的合理选择,分析计算加工误差,应用宏程序对变量的处理功能进行适时的动态补偿,可以最大限度地减少加工误差,获得理想的效果。In connection with machining of the stepped shaft, establishes a mechanics model of bending deflection , deduces a universal formula- an equation of deflective skew curve - for simply supported beam of variable cross - section bending deflection by integral calculus. The formula is applies to machining part＇s actual computation, analyzes and calculates machining errors based on reasonable selecting the technological parameters, then lends timely dynamic compensation by macroprogram with processing function of variable. This way may reduce farthest machining errors and gain perfect results.
