Background
The high-speed arc discharge technology is an efficient processing mode for melting and removing conductive materials by utilizing the large energy of an arc, the arc column stays at a certain point to melt or vaporize the materials at the position and is taken away by flushing liquid to form a bowl-shaped pit, but the arc generation position is difficult to predict, a large number of pits can degrade the surface quality while the arc efficiently removes the materials, even if the surface roughness is slightly reduced by adjusting electric parameters and non-electric parameters, the arc processing still cannot meet the roughness requirement of industrial products, and the processing efficiency is also reduced. At this stage, a finishing process is usually performed after the arc machining to meet surface quality requirements, such as cutting, grinding and electric discharge machining, wherein the milling process is most widely used.

According to the method, rough machining and finish machining are achieved on the same machine tool in a mode of replacing a machining machine head, machining time is shortened, machining efficiency is improved, but the two working procedures are sequential, cutting machining is performed after short arc machining is completed, the machining cannot be performed simultaneously, a certain time is required for replacing a cutter, and the machining time still has an optimization space.

The short arc machining and the electrochemical machining are performed simultaneously, so that the machining time can be reduced, the efficiency of the electrochemical machining is low, if the short arc machining tool electrode is matched with the high-speed feeding of the short arc machining tool electrode, the improvement of the electrochemical on the surface quality is very small, the low-speed feeding can obtain better surface quality, and the machining efficiency can be reduced.
As known from patent search, patent CN109702281a discloses an arc grinding composite tool electrode, which uses a hollow ring electrode to perform arc discharge machining to obtain a higher material removal rate, and a grinding head is mounted on an inner ring of the electrode to perform grinding machining through high-speed rotation of the tool electrode to obtain a better surface quality. The arc machining and the grinding machining can be simultaneously carried out, the machining time is reduced, but the diameter of the outer ring of the annular electrode is larger than that of the grinding head, the arc machining range is larger than the grinding machining range on a machining path, and the track overlapping rate is required to be increased during machining to ensure that the surface of a workpiece is acted by the grinding head, so that the machining time can be correspondingly increased, and the machining efficiency is reduced.
