The repeated cutting process parameters of middle speed wire eletrical-discharge machines are studied. Four factors such as pulse width,duty cycle,peak current and wire speed are adopted in the process. The comprehensive scoring method is used to deal with the data,which makes the multi objective optimization to turn into the single objective optimization. The technological parameters of the second cutting and third cutting are optimized by orthogonal test,and the process parameters are verified. The experimental results can provide reference for middle speed WEDM process.
