Multi-objective optimization of the ecm process

摘要: Abstract Optimization of process parameters is helpful in efficient working the and, hence, lowering cost machining. ECM has been achieved by considering only one objective at a time from metal removal rate, geometrical accuracy, and total cost. From practical point view, solution ecm problem satisfying all three objectives simultaneously highly desirable. In proposed model, multi-objective involving formulated producing nonlinearized equations. These are then linearized regression analysis converted into goal programming format. Finally, solved partitioning algorithm. It concluded that tool, or cathode, remains safe optimal values design variables obtained examples discussed. The value voltage when rate objective, found to be higher than case accuracy requirement also satisfied.
