ABSTRACT:
A holding fixture and method for using the same are disclosed which enable great accuracy in performing measurements of concentricity, diameter, and wall thickness of a cylindrical workpiece. The present invention supports the workpiece for rotation at two fixed locations characterized by orthogonal tangents, while making measurements at a location on the workpiece on the opposite side of one of the support locations. The device is simple and economical in construction, easy to use while providing reliable measurements of the specified parameters, and it improves production line operation by expediting particular measuring procedures.
