Design of the Intelligent Progressive Control Scheme and the Hardware Circuit of the Controller for the Wire Cutting Machine of Special Processing

In view of the problem of large demand and high cost for upgrading wire cut electrical discharge machining(WEDM)in special processing equipment,a low-cost equipment improvement scheme is proposed.On the premise of not increasing hardware investment,this paper puts forward the improvement scheme of gradual using of electrode wire in fine and rough machining,and designs the hardware circuit schematic diagram and PCB board of intelligent progressive wire controller.Through the cooperation with related manufacturers,it is shown that the intelligent progressive wire control scheme and hardware circuit can reduce the cost of improvement to the maximum extent,and can improve the machining accuracy,surface roughness and machining consistency of the machine tool.
