Study of the Effects of Applying CAD-CAM Techniques to A Shipyard Sheet Metal Shop.

摘要

One of the main functions of the sheet metal shop in a shipyard is to produce the duct work required for ventilating, heating and cooling the various parts of the ship. Because of the nature of this work and the craftsmen and the machine tool needs for carrying it out, the sheet metal shop becomes a likely candidate for the production of many other special metal parts needed in ship construction. To improve the efficiency of the sheet metal shop at the Avondale Shipyard facility in New Orleans, the introduction of a CAD-CAM system was considered in 1982. As the study progressed, it became apparent that the introduction of the CAD-CAM system being considered offered other opportunities to the operation. Not only would the system automate the production of duct work fittings, but it would also help reduce the labor and time needed for producing many other parts. In addition, it was determined that it could also serve as a DNC link between the Shipyard's ISM data base and the CNC flame cutting machines in the plate shop.
