ABSTRACT
This paper reports on 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. In each case the system determines the
material utilization by calculating the minimum
circumscribing rectangular area which contains the two
shapes. The developed system has been written in ‘Visual C’
on an IBM-Compatible Personal Computer. The optimal
nesting is calculated from overall trials. The system is applied
on different shapes and proved to give a reduced computation
time for arriving to the optimal position with higher
utilization ratio and minimization of scrap.
