Sheet Metal Production of Magnesium

Abstract In this paper, we present an approach to recognize symmetries of bent sheet-metal parts at different manufacturing stages. This approach is based on Waltzman’s (Waltzman, 1987) 2D symmetry detection algorithm. 3D symmetry is recognized by considering its 2D symmetry and the associated bending transformations. We show, by recognizing that the part is symmetrical, that the planning complexity for processes in sheet-metal production can be greatly reduced. This paper is motivated by the fact that a significant percentage of sheet-metal parts are symmetrical. We have studied over 200 industrial parts and over 40% of them are symmetrical. Examples from sheet-metal nesting (layout planning), bending, stacking, product decomposition and assembly planning are discussed.

Pallets and forklifts equipped with Radio-Frequency Identification (RFID) technology can be a suitable option for bridging the information gap between cutting and bending stages in sheet metal production. However, a decision on how tagged pallets can be assigned to their content needs to be made. In this paper, a reactive and a proactive approach for the near-automatic identification of parts on pallets after cutting are discussed and their performance is evaluated through a series of simulations. In both approaches, the nesting information along with the measured net weight of the pallets are used to determine the parts on top of each pallet. The influence of the alternative solutions problem on the performance is investigated for both approaches. It is concluded that the actual decision on the approach selection depends on the time that is required for each recalculation and each pre-allocation. Those times are workshop dependent and, therefore, a decision should be made for each workshop specifically.

A Value

Aerospace industry is a value-added and technology integrated industry. Sheet metal parts are important portion of aerostructures. The sheet metal production line combines five different routing types together. This study tries to make a comparison between job shop layout and cellular layout with lean concept. According to precedence diagram of sheet metal fabrication process, the model and measurement indicators can be constructed. The simulation software SIMPROCESS is then used to simulate the real-world cases under dynamic conditions. After the verification and validation process, we analyze the results that collected by simulation and provide the suggestions for the layout of aerospace sheet metal process.
