【Abstract】 A new method based on spatially stratified index model of machining equipment to the maximal range of work is presented for detecting the collision of NC programs. The method changes the problem of collision between 3D obiects into the problem of judging positional relation between a point on a plane and a closed profilogram, by which the complexity of collision detection is reduced and the efficiency of collision detection is increased. Examples on algorithm with microcomputer as basis of hardware are given.更多还原
