✦ Synopsis

This paper presents an automated manufacturing system for drilling sheet metal parts . All stand-alone systems such as the robot, a set of reconflgurable fixtures and the CAD/CAM workstation have been integrated into a flexible manufacturing system . This system analyzes and evaluates a given fixturing layout and assembles the reconfigurable fixtures automatically using a robot manipulator . An optimum fixturing layout and assembly are achieved by examining the workpart from a stress-strain point of view . In addition, issues such as geometric constraints, yielding and buckling, database design, collision detection, fixturing sequential control and the automatic assembly of fixture elements are considered . The computational and analytical concepts for the reconfigurable fixturing and drilling system are also presented in this paper .
