METHOD FOR PREVENTING COLLISION WHEN REGRESSION THROUGH THE ORIGIN

摘要

Name; how to prevent feed shaft collision when returning to origin.;Purpose; To prevent the bearing and ball screw support from colliding with acceleration by decelerating the axial movement of machine tool in multiple stages.;The process of setting the prohibition of rapid movement in the NC data area, storing the current machine position data, selecting the corresponding axis in the homing mode, and the homing direction in the homing command for each axis. If it is not in the direction, it performs normal origin return, if the axis's current position is within the rapid traverse prohibited area in the-direction, it performs deceleration, and stops the machine as a whole if it does not stop after deceleration. .;Efficient; Even if the return to the origin in the stroke range, the feed rate is reduced by multiple steps to prevent the collision between the bearing of the shaft and the ball screw support, thereby preventing the ball screw damage and bearing damage.
