In this paper, the authors explain the design of a Computer-Aided Sheet Nesting System (CASNS) for the nesting of two different or two similar shaped sheet-metal blanks on a given or coil stock. The proposed system extracts the required shape geometrical information directly from CAD data base. Initially, the two shapes are overlapped and the different positions can be obtained by fixing the first shape and moving the second in steps in X-direction until no overlapping occurs. After that, the movable shape is moved by a step in Y-direction and repeated the motion in X-direction. Trials after, rotating the movable shape taking grain orientation constrains into a consideration.
