The Sheet Metal process group lets you estimate manufacturing times and costs for a wide variety of sheet metal fabrication processes and subsequent machining operations. aPriori's sheet metal process models include estimates of hard tooling costs. This chapter describes the costing details and inputs that are available for various hard-tooled Sheet Metal processes. For detailed information on soft-tooled processes, see the chapter Sheet Metal—Soft Tooled. See also Sheet Metal--Hydroforming, Sheet Metal—Transfer Die, and Sheet Metal—Stretch Forming.
