Determination of the Number of Fixture Locating Points for Sheet Metal By Grey Model
In the process of the traditional fixture design for sheet metal part based on the "N-2-1" locating principle, the number of fixture locating points is determined by trial and error or the experience of the designer. To that end, a new design method based on grey theory is proposed to dete...
