Information : Expert Systems
Several expert systems have been developed at Oak Ridge National Laboratory (ORNL) to capture the knowledge of experienced designers and machine tool operators. These expert systems have been developed using FORTRAN instead of commercially available expert systems development tools. Three examples of expert systems are the Oralloy Casting Advisory System, Hydroforming Tool-die Design Advisor, and the Rolling Information Generation System.
The Oralloy Casting Advisory System consists of two parts a database of casting data and an advisor for new castings. The database contains mold data, composition data, and casting operation data. The user of the expert system provides part size and tracer percentages. The system will determine the mold design, casting method, and input tracer amounts. The Rolling Information Generation System is used to assist in the manufacture of rolled plates. The user of the expert system provides the size of reheat cages, the minimum size the plate can be re-rolled, the maximum diagonal size of the mill, and the power of the shear. The expert system then creates a rolling schedule, which tells the roller operator how much to reduce the size of the plate on each pass, and when to rotate the billet to obtain the desired size.
