随着数控机床性能及零件复杂程度的不断提高，数控（NC）编程的难度日益加大，NC程序的故障率也越来越高。如果NC代码不正确，很可能发生零件被过切或少切，刀具和零件、刀具和工作台之间的干涉或碰撞现象。为了验证和保证数控NC程序的正确性，防止干涉和碰撞发生，传统上采用?
With the continuous improvement of CNC machine tool performance and parts complexity, NC programming is more and more difficult, and the failure rate of NC programs is also getting higher and higher. If the NC code is not correct, it is likely that the part is over or undercut, interference or collision between the tool and the part, the tool and the table. In order to verify and ensure the correctness of NC NC program to prevent interference and collision, traditionally adopted?
