摘　　要：数控仿真是代替传统试切来验证加工程序的重要手段。首先介绍了三维图形几何仿真数学模型,根据数控ANC_45M加工中心的图形仿真需求,对图形仿真器数学建模、图形裁减和三维图形层次感等问题进行了研究与设计,并在加工中心的控制系统中用C语言实现。最后用加工程序进行验证,结果表明采用层次感的图形显示方法,对表达图形的真实感有所改善,图形仿真器完全能够满足数控程序调试的需要。NC simulation is an important means that replaces tradition try-cut to test machining program. Geometry model of three-dimension graphics is introduced at first. Then math model, graphics cut down, three dimension lays of graphics simulator are researched and designed according to the graphics demand of ANC-45M machining center. The graphics simulator is implemented via C language in control systems of machining center. Finally, the practice through machining center program shows reality sense of graphics is improved to some extent and graphics simulation meet the need to debug numerical control program.
