THE METHOD OF DETERMINING THE MAGNITUDE OF A DIMENSION OF A BODY OF SEMICONDUCTOR MATERIAL UNDERGOING A MECHINING OPERATION WHICH COMPRISES THE STEPS OF SUBJECTING A BODY OF SEMICONDUCTOR MATERIAL AND A BODY OF PIEZOELECTRIC MATERIAL HAVING A CORRESPONDINGLY ORIENTED DIMENSION THE MAGNITUDE OF WHICH DETERMINES ITS RESONANT FREQUENCY TO A MACHINING OPERATION SIMULTANEOUSLY REDUCING THE CORRESPONDING DIMENSION OF EACH OF SAID BODIES AT THE SAME RATE, AND MEASURING DURING THE MACHINING OPERATION THE FREQUENCY OF THE PIEZOELETRIC CURRENTS PRODUCED IN SID BODY OF PIEZOELECTRIC MATERIAL BY THE STRESSES CAUSED BY THE MACHINING OPERATION.
