【Abstract】 The keys to adaptive control with optimization of machining operations are modeling of cutting process and selecting of real time optimal strategy.In this paper,we propose to moldel the machining process using artificial neural network and realize on line optimization using genetic algorithms.A system for adaptive optimization of cutting parameters such as feed rate and spindle speed in a face milling operation for maximizing the material removal rate without violating machining constraints is set up.更多还原
