Upon the Modeling and the Optimization of the Debiting Process through Computer Aided Non-Conventional Technologies

Abstract

he debiting process of the remarkable properties materials can be managed through unconventional technologies as the complex electrical erosion. This paper presents the mathematical modeling and simulation of a particular processing to establish the shortest cutting time and the better surface quality based on the best combination of input parameters. This paper presents the modeling of the previous experimental results to obtain a mathematical dependence of the output parameters (processing time, surface quality) on the input parameters (voltage or current). All the experimental data are memorized on a database and for each particular debiting process a new dependence is built. The previous results database is built using personal experiments and results presented in references. These results were obtained using a research scheduler and a computer-based application organizes these results into a database separated on different mechanical processes, work conditions, materials, devices. All the experiments applied in the Romanian laboratories or practical applications of the nonconventional technological processes in the factories were based on the particular conditions of one activity. This papers presents the technical implementation of a computer-aided solution that keeps all previous experimental data, optimizes the processing conditions and eventual manage the driving gear. The flow-chart we present in this paper offers a solution for practitioners to reduce the electrical consumption while a technological processing of special materials is necessary. The computer program and the database can be easily adapted to any technological processes (conventional or not). No general available mathematical formulas for the dependency of the output parameters on the input ones are yet presented. The software we developed uses interpolation to determine the best polynomial or exponential equation and offers the combination of input values to minimize the processing time and/or to maximize the quality of the processed material.
