Automatic tool position compensating system for a numerically controlled machine tool

Abstract

Abstract FURTHER, AS DESCRIBED IN U.S. APPLICATION S.N. 839,723, FILLED JULY 7, 1969 IN THE NAMES OF TANABLE ET AL. AND ASSIGNED TO THE ASSIGNEE OF THE PRESENT APPLICATION, BY CONSTRUCTING THE MAIN SPINDLES THEREOF WHILE MAINTAINING A DEFINITE POSITION RELATIVE THERETO. THE MEASURING ELEMENT COUPLED TO A CONTROLLER FOR THE MACHINE TOOL FOR SENSING THE DIMENSIONS OF THE WORKPIECE UPON RECEIPT OF A COMMAND SIGNAL FORM A TAPE READER THROUGH THE CONTROLLER. IT PRODUCES A TOOL DEVIATION SIGNAL REPRESENTATIVE OF THE DIFFERENCES BETWEEN THE SENSED DIMENSIONS AND THE DIMENSIONS CALLED FOR BY COMMAND INFORMATION READ BY SAID TAPE READER. A MEASURED SIGNAL PROCESSOR IS COUPLED TO THE MEASURING ELEMENT AND THE CONTROLLER AND TO A MISCELLANEOUS FUNCTION DEVICE FOR CALCULATING THE DEVIATION BETWEEN THE MEASURED DIMENSION AND THE CORRESPONDING PROGRAMMED DIMENSIONS FROM THE OUTPUT FROM THE MEASURING ELEMENT AND TO MEMORIZE THE RESULT OF THE CALCULATION AS A COMPENSATING VALUE. THE COMPENSATING VALUE MEMORIZED IN THE MEASURED SIGNAL PROCESSER IS TRANSMITTED TO THE CONTROLLER AS PULSES SO THAT THE COMPENSATION OF THE POSITION OF THE CUTTING TOOLS AND THE TABLE OF THE MACHINE CAN BE CARRIED OUT AUTOMATICALLY, DEPENDING ON THE DIMENSIONS SENSED BY THE MEASURING MEANS.
