Tooling is an important area in the manufacturing of various sheet metal products. This aspect can be extremely expensive as well as time consuming. The increase in the complexity of tooling for any operation results in a corresponding increase in the time and costs required in developing such tooling. The ideal candidate operations for rapid tooling (RT) have been those for which it is difficult to develop tooling by the usual methods. The quest is to produce complex tooling quickly and at low cost. This paper describes the development of RT techniques for the production of sheet metal drawing tooling by using a combination of stereolithograhy and nickel electroforming processes. Two types of prototype tools have been designed and manufactured. The first type is a stereolithography QuickCast pattern infiltrated with aluminium-filled epoxy designated as QuickTool, and the second type has been manufactured by combining stereolithography technique with the nickel electroforming process. While the QuickTool may be indeed rapidly manufactured it can be only a prototype tool, as the material it is made of does not render much durability. On the other hand, the nickel electroformed tool is far more durable and can withstand more extreme working conditions. By combining nickel electroforming and the stereolithography process, press tools for sheet metal forming have been successfully produced. Further, the developed tools have been evaluated in the press metal forming process by producing components with 0.8 mm aluminium sheets.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
