Abstract

Abstract

For studying Wire-free WEDM machine tool processing the inner surface cracking groove in the double sides of the connecting rod quality and efficiency, the new Wire-free WEDM machine tool is used as the experimental equipment, which carries out the single-station processing and double-station processing experiment, among the double-station processing experiment is divided into the different types and the same type of connecting rod cracking groove double-station processing experiment. The single-station processing experiments have proved that the experimental sample groove depth H decreases firstly and then increases by the wire moving frequency increasing in the single-station processing, and the groove width W is increased by the pulse period; the same type of double-station processing proves that the groove depth H is significantly affected by the power supply voltage. The width W of the cracking groove of the left station experimental sample changes from 30 to 40 μs, and the groove width W of the right station experimental sample increases with the increasing of voltage. All experimental groups can meet the preparation requirements of connecting rod cracking groove by 20 s, and it have good an application prospective.
