ABSTRACT:
A method for monitoring the quality of a machining operation, such as a friction stir welding operation, in which a tool is rotatably driven by a motor during the machining operation. The energy consumption of the motor is determined from the initiation and to the completion of the machining operation. That energy consumption is then compared against a predetermined energy threshold. In the event that the energy consumed during the machining operation is less than the predetermined threshold, an error signal is generated.
