Abstract
Sheet metal parts are widely used as main constructional elements of industrial products such as any household electric appliances and electronic equipments. Since a process planning of sheet metal part is so complicated, that computer aided engineering for sheet metal part has been investigated. In this paper, we focus on the shape of bending punch which is determined according to the conditions of interference. The proposing method can be used for the determination of a suitable punch and check of punch by using pattern recognition. We applied this method to actual sheet metal bending process of sheet metal parts in a shop floor of a sheet metal manufacturing industry as a case study, and validity of this method was confirmed.
