Fixtureless assembly
WebDec 8, 2015 · Robotic assembly systems either make use of expensive fixtures to hold components in predefined locations, or the poses of the components are determined using various machine vision techniques. Vision-guided assembly robots can handle subtle variations in geometries and poses of parts. WebAbstract A method is presented for fixtureless assembly of simple sheet metal parts (i.e. consisting of flat patterns and simple bends) used in the aircraft industry. Current industry practice relies on manually intensive procedures and rigid fixtures for part assembly. The present method relies on carefully toleranced alignment holes that are computer …
