  • Intelligent CAD/CAM systems for CNC programming - an overview
    Balič, Jože
    The aim of the presented research is the design of a computer-aided, intelligent and GA-based programming system for CNC machine tools and tool path planning. The first step is geometrical feature ... recognition and classification. On the basis of recognized features the module for GA-based determination of technological data takes place in order to determine cutting tools, cutting parameters (according to workpiece materiač and cutting tool material) and detailed tool path planning. The material, which will be removed, is split into several cuts, each cut consisting of a several number of basic tool movements. Then GA operations reproduction, crossovr and mutation are applied. The process of GA based optimization runs in cycles in which new generations of individuals are created with increasing average fitness of a population. During the evaluation of generated NC programs several rules and constraints were taken into account, which represent the fitness function: fast and cutting tool movement, collision, clamping and minimum machining time. The system was developed for PC and tested through simulation process. It needs to be tested more in detail in the real manufacturing environment. The paper presents a contribution to intelligent systems in a production environment. Genetic based methods were used to solve engineering problems.
