ELECTRICAL CONTROL SYSTEM FOR THE LIMITATION OF STROKE-FREE RUNS ON MACHINE TOOLS, ESPECIALLY RODER MACHINES

摘要

The invention relates to an electrical control system which is used to reverse the movement of tool carriers 55 or of component holders, for example on the machines to be eroded 56; ON MACHINES OF THIS TYPE, THE RACE IS INFLUENCED BY VARIOUS DISTURBING SIZES, SO THAT, OFTEN, THE REAL DISTANCE BETWEEN THE TWO POINTS OF INVERSION DOES NOT CORRESPOND TO THE DESIREE RACE. / P p THE SYSTEM OF CONTROL IN ACCORDANCE WITH THE INVENTION INCLUDES A DEVICE FOR CONTROLLING THE RACE 5 WHICH, FROM THE DIFFERENCE BETWEEN THE SETPOINT VALUE AND THE INSTANT VALUE CORRESPONDING TO THE INVERSION POINTS, SETS A CORRECTIVE VALUE BY WHICH THE RACE IS CORRECTED IN SUCH A WAY THAT ALL DISTORTING QUANTITIES THAT MANIFEST BE CONSIDERED AND ELIMINATED FOR ORDER. / P
