expended step meaning in Chinese

耗尽级

Step - nc ( iso14649 ) expends step into the area of cnc and renews the data interface between cax and cnc , which helps cnc system to use data models of products in three dimensions according with step directly in order to output nc programs then control machines directly , eliminate choke points of the information stream between cax , such as cad , capp , cam , cae , ped , erp and so on , connect the design product information and manufacturing product information on the base of step in the form of object - orientation , and change the traditional movement and switch control - orientation numerical programs into object - orientation programs
Step - nc ( iso14649 )将step扩展至cnc领域,重新规定了cax与cnc之间的接口,其目的是: cnc系统能够直接使用符合step标准的cad三维产品数据模型,直接产生加工程序来控制机床;在step的基础上以面向对象的形式将产品的设计信息与制造信息联系起来,消除cax (如cad 、 capp 、 cam 、 cae 、 ped 、 erp等)与数控系统之间信息流瓶颈;将传统的面向运动和开关控制的数控程序改变为直接面向加工对象的数控程序。
