Abstract
In order to detect accurately a seating of clamped body and a clamping force at a seating, the workpiece supporting device has plural seating mechanisms. Each of the seating mechanismsincludes a load sensing elementreceiving a clamping force or a fixing force. The load sensing elementconsists of a material having a characteristic that said load sensing element is not substantially deformed by an applied load, especially it consists of a composite material dispersing a material having a pressure resistance effect or a magnetic resistance effect in a matrix of an electric insulation ceramics material. An abnormal clamping or fixing of the clamped body and an abnormal overload are detected by detecting an output from plural load sensing elementssupporting the clamped body.
