Introducing various type of technology for texturing of sheet rolled metal and modeling and developing an intelligent system for electrical discharge texturing

This paper divided into two parts. In the first part various type of technology for texturing of sheet rolled metal Is introduced including, shot blasting (SB), laser beam texturing (LBT), ion beam texturing, electron beam texturing (EBT), and electrical discharge texturing. Advantages and disadvantages of various type of texturing are discussed and compare with each other. In the second part of the paper, an expert system is modeling and developed for estimating surface roughness and peak count in concurrent engineering environment for electro-discharge texturing (EDT). The expert system links with A feature based CAD system in order to extract design data. Description of different size and classes of sheet rolled material is extract from CAD data base. Attributes of seventy different type of metal for work piece, eight different type of material for tools, and different type of dielectric, are stored in databases. The knowledge base is linked with CAD data base. The surface roughness and peak count and other necessary variable, are estimated. The system provides useful information for product designers and also advises manufacturing engineers to select optimum machining parameters. For validity of the expert system, out put of expert system compars with output of experimental. The results shows that estimating of machining time and cost, surface roughness and peak count of intelligent system 10 percent better than experimental.
