NC PROGRAM GENERATING METHOD FOR INTERACTIVE NUMERICAL CONTROLLER OR AUTOMATIC PROGRAMMING DEVICE

摘要

PURPOSE:To equalize the primary working time and the secondary working time to improve the working efficiency by determining the division point between the primary working and the secondary working based on data of a parts form. CONSTITUTION:A graphic control circuit 15 converts a digital signal to a display signal to give it to a display device 16, and a material form, a parts form, a working definition picture, the position display of each shaft, parameters, etc., are displayed. In this case, a material form 2 and a parts form 3 are defined, and the position of a division point P is calculated based on them, and an overall working area to be cut is calculated, and such division point P between the primary working and the secondary working is defined that both areas obtained by dividing its overall area by a segment perpendicular to the Z axis of a four-axis lathe are equalized to each other. A primary working cut area 5 and a secondary working cut area 6 are determined based on the division point P.
