Abstract
The arrangement enables controlling the speed of advance of the tool part of a machine tool during its approach phase toward a workpiece and reducing such speed as soon as the tool contacts the workpiece. It includes an acoustic sensor adapted to detect the signal emitted at the instant of contact, an electronic circuit for processing such signal and a motor responding to the circuit to regulate the speed of advance of the tool part. The sensor is fastened to a feeler mounted on the machine framework by means of shock absorbers, said feeler being arranged to be in contact with the workpiece or its carrier.
