偏心轴（孔）类零件的数控加工通用宏程序开发

摘要

探讨了在不做机械偏置的情况下利用数控车床车削偏心轴（孔）零件的方法，并建立了数学模型，编写了偏心轴类零件车削通用宏程序，解决了切入点定位的一致性问题。%This paper explores the method of turning eccentric shaft/hole on NC lathe without mechanical offset ,establishes the mathematical model ,solves the consistency problem of entry points ,and writes the universal turning macro-program for eccentric shaf t .
