Problems solved by technology

However, there is a problem of uneven discharge in the current EDM milling process.
And electrode loss is an inevitable problem in EDM. In EDM, if the electrode cannot be compensated in time, the integrity of the machined surface will be poor.
In addition, various factors often affect the normal discharge of electric sparks in the process of EDM. In EDM milling, due to the rotation of the tool, the discharge gap changes with the rotation of the electrode, so it is difficult to grasp the law of electrode loss, and during the process, due to The discharge pulse is uncertain on which part of the electrode to discharge, and the gap between the entire electrode and the workpiece will be highly inconsistent, which will affect the next machining discharge
