A computing device simulates a process of processing an object. The computing device calculates a moving space when a minimum bounding box of a model of a blade moves from a position point to an obtained path point. The computing device cuts a triangulated model of the object when the triangulated model of the object intersects the moving space.

CNC加工程序是文本文件的格式，不直观，只有通过CNC加工实际的产品才能知道最后的加工效果。如果CNC加工程序编写得不是很好，加工效果可能不满足要求，并且在产品加工过程中刀具及CNC机台可能会被损坏。
