Automatic programming device and manner null of numerical control program for board component disconnection

摘要

PURPOSE:To perform cutting work of a thick plate without burning damage by generating automatically a numerical control program in accordance with material, thickness and working shape of a plate member to be cut. CONSTITUTION:At the time of generating the NC cutting program of the plate member, an NC program generating means to set a working condition of a parameter value large than a hole or a polygon at a first step of cutting startup operation and perform cutting at a second step and carry out approaching operation of the cutting plane to the position to be worked actually at a last third step is provided. By this method, an automatic drop of a melt generated at the time of cutting using a laser beam, etc., is made possible and burning damage accompanied by cutting of the thick plate is prevented.
