Sheet metal parts have been widely used in industry and much information for parts has been accumulated in the database. In planning the manufacturing process of a sheet metal part, if the similar process plan of the part to be manufactured can be retrieved, the process plan would be faster and more consistent. In this paper, the effective method of searching the sheet metal parts with the similar process plan is proposed. This method consists of two stages. The first flat pattern drawings of the parts with the same set-up numbers are classified into several topological construction patterns. The second, the parts which possess the same process plan with the part to be manufactured are selected based on the process plan obtained by the process planning expert system, including the geometric element of the flat pattern. The expert system is operated by taking the geometric element of flat patterns into consideration. The effectiveness of the method is described and illustrative examples are shown.
