WEAR, LUBRICATION FAILURE AND PRODUCT DEFECTS AUTOMATED MACHINING IS PROPOSED.

WEAR, LUBRICATION FAILURE AND PRODUCT DEFECTS AUTOMATED MACHINING IS PROPOSED. THE INSTRUMENT WOULD CONTINUOUSLY MONITOR AUTOMATED METALWORKING ON LATHES, MILLING MACHINES, DRILL PRESSES AND PUNCH PRESSES, AND WOULD BE CAPABLE OF SELF-OPTIMIZING ADAPTIVE MACHINING CONTROL. A THEORETICAL BACKGROUND IS PROVIDED WHICH INDICATES THAT TOOL WEAR, LUBRICATION FAILURE AND PRODUCT DEFECTS CAN BE IDENTIFIED BY MEANS OF CHARACTERISTIC FREQUENCIES EMITTED IN THE ULTRASONIC RANGE. EXPERIMENTS ARE PROPOSED TO CONFIRM THE THEORY ESTABLISH THE LABORATORY FEASIBILITY OF THE CONCEPT AND DEFINE THE OPERATING REGIME AND SIGNAL PROCESSING CHARACTERISTICS OF SUCH AN INSTRUMENT SO THAT A PROTYPE COULD BE CONSTRUCTED.
