Effect of Geometrical and Process Parameters on Utilization of Sheet Material in Plasma and Laser Cutting Processes
Nesting, an optimal arrangement of 2D sheet metal blanks on a large sheet, is a very important CAM activity in sheet metal industry since it influences the sheet material wastage significantly. In this work, the effect of part geometry, part size, part quantity and cutting process parameters on material wastage while nesting of two-dimensional shapes in rectangular sheets is analyzed. The nested patterns are generated by a professional commercial package, and material wastage is captured by varying the part geometry, size and quantity. The results are analyzed for laser and plasma cutting processes by considering corresponding parameters such as kerf width, bridge width, part-to-sheet distance, lead-in and lead-out distances. The results are compared with data available in the literature.
