Automatic Recognition System for Relative Position of Required Shape in Workpiece Space

Abstract This paper deals with an automatic recognition system for determining a relative position of a required shape in the workpiece space such as large castings or forgings. The proposed automatic recognition system consists of a five-direction measuring system for obtaining the entire workpiece shape, an automatic recognition processor for determining the relative position of geometric model in the measured workpiece space, and an automatic marking system which put marks on a workpiece for giving the information of reference planes and points. Satisfactory results have been confirmed by some assessment tests.
