2、用带来了革命性的变化,对传统的制造业。该机主要用于椭圆轴支承皮带轮,齿轮,凸轮和连杆传动件,传动扭矩,它是机器的重要部分。因为很多地方有很多相同的地方,特别是轴类零件,由于对称性,所以很多部件都是相同的,对同一零件的数控加工,通常可以使用子程序编程,可以大大提高工作效率。重复定位精度和数控机床的定位精度很高,易于保证椭圆尺寸的一致性,只要工艺设计和程序是正确的、合理的,可以保证零件获得较高的加工精度,也便于机械加工过程质量控制的实施。关键词: 椭圆轴;数控编程;AbstractElliptical shaft in the machine is mainly used for supporti
3、ng the beltwheel gear, cam and connecting rod transmission parts, transmissiontorque, it is an important part of machine parts. Because many parts havemany of the same parts, especially shaft parts, due to symmetry, so thepart of a lot of parts are the same, for NC machining of parts of the samecan
