ABSTRACT:
An adaptive work table-reciprocation control system and method that can reduce a grinding time. The system uses a vibration sensor head installed on a chuck surface in the vicinity of the workpiece to detect a vibration signal emitted from the contact zone between the grinding wheel and the workpiece. When the value of the vibration signals falls below a trigger level, a work table direction of motion is reversed.
