Abstract
An EDM (electron discharge machining) dressing device with cup electrode was developed based on the requirements of metal-bond diamond arc wheel dressing. The structure characteristics of the device were introduced. The effect of the size of metal-bond arc wheel and cup electrode on arc shape of wheel was analyzed. The formula of arc shape was deduced according to the size of cup electrode and arc wheel. Simulation was done with Matlab. Results revealed that the arc radius deviation of 10 mm wide arc wheel was within 0.02 mm. After experiments with the EDM dressing device, the shape error between dressed wheel and simulation was within 3 μm.
