ABSTRACT:
A vibration sensor, located on a chuck member for a workpiece and rotating therewith, detects the signal emitted at the instant a tool member contacts the workpiece. The vibration sensor produces an output signal to modulate a transmitter and a receiver fastened to the machine tool frame receives the information broadcast by the transmitter. The information is processed to produce a signal which reduces the speed of a motor controlling the advance of the tool member. The speed of the tool member is thus reduced as soon as the tool member contacts the workpiece. The arrangement is particularly suited to machines for grinding interior diameters and prevents damage following accidental collision of the workpiece and tool member.
