A general method of optimization based on GA (Genetic Algorithm) was proposed and researched. The speed of calculation was so fast that it was suitable for the optimization of cutting parameters in automated manufacturing system. Based on the existing metal cutting data base system, related technologies and the requirements of machining center for cutting data, a general NC cutting database system was built. Based on the theoretical research, a package of software of management and optimization of cutting parameters was implemented.Using the system a great deal of technologists are released from the repeated handwork, and rationalization and standardization of cutting parameters are realized,productivity of the machining center is improved and well economy benefits are obtained.
