ABSTRACT:
The invention relates to a method for checking performance of the cutting-off operation on automatic lathes for working bar material or the like. In accordance with the invention, operating conditions are initiated at the end of a prescribed time interval for the cutting-off operation which result in relative rotation of the spindles in opposite directions in the event that the material has been completely severed at the cutting-off point. A discrepancy between the specified and the actual relative rotation is interpreted as a system failure due to the presence of a material link at the cutting-off point, whereupon a corresponding error signal is triggered.
