Fixture layout optimization for deformable sheet metal workpiece

The purpose of the fixture layout design is to ensure the fixture positioning accuracy, which affects the resultant geometric variation of the positioned workpiece directly. The N–2–1 locating principle is widely applied in the fixture design for deformable sheet metal workpiece, not only for locating the workpiece, but also for restraining the excessive workpiece deformation. This paper proposes an approach to optimizing fixture layout for the...
