Manufacturing Features in Cutting Shapes and Punching Holes in Sheet Metal

چکیده
By examining sheet metal parts it is rather evident that each sheet metal shape has its own manufacturing procedure. There are several manufacturing devices behind each procedure. This means that each shape can be divided into manufacturing features, which consist of shapes of sheet metal and their manufacturing methods. When creating rules and structures for manufacturing features, it is possible to prepare simple guides for engineering designers so that they can design parts which are easy to manufacture. A manufacturing guide can be a kind of database. A designing engineer may follow the guidelines of the database. It proposes different kinds of possibilities to produce sheet metal parts. This enables the design of products which are easy to manufacture. In addition, it allows the designer to diversify his or her knowledge of manufacturing methods. In this study, simple sheet metal parts and their manufacturing features are studied. For example, simple shapes such as holes can be made in several ways. Cutting a hole consists of several attributes which determine the requirements for manufacturing. This study tries to validate what kinds of factors are needed in order for the engineering designer to design parts which are simple to manufacture.

Design study of the geometry of a punching/ blanking tool
The cost of tooling in sheet metal industries contributes a considerable part to the overall cost of manufacturing a component. It is therefore imperative to keep down this cost by ensuring that the tool works for a long period in production without interruption. One way of achieving this objective is to reduce the stress on the tool during punching/blanking. This paper deals with the study of ...
متن کاملEvaluating Sheet Metal Nesting Decisions
This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision{makers plan production and evaluate the impact of changing the nesting policy. In addition, we use them to formulate a nesting optimization problem. Finally, we use the models to evaluate the sensitivity of the nesting policy to manufacturing parameters....
