Material cost governs a major share of product cost in sheet metal products and hence it is advisable to design parts/assemblies for maximum material utilization. All opportunities which can result in improved material utilization have to be analyzed. An interesting case is shown in Fig 1 which gave an utilization of only 39.58% with the […]

Methods and Issues in Determining Material Cost for Sheet Metal Parts
Cost of a sheet metal part comprises three major cost components such as material cost, processing cost and overheads. Determining accurate material cost has always been an issue. Theoretically material cost can be calculated as follows: Material Cost = Area of the flat pattern * thickness * (weight per unit volume) * cost per unit […]
