Description

technical field [0001] The invention relates to electric discharge machining, in particular to a device and method for detecting the state of electric spark gap discharge based on cluster analysis. Background technique [0002] EDM is a special processing method that removes the surface of the workpiece through the instantaneous high temperature generated by the pulsed spark discharge between the electrode and the workpiece, so as to meet the requirements of a certain shape and surface roughness. EDM is not affected by the strength and hardness of the workpiece, and there is no macroscopic cutting force. Especially suitable for machining complex shapes that are difficult to machine. It has great applications in aviation, aerospace, automobiles, electronics, and molds. [0003] The discharge state of the gap usually has three types: no-load, spark, and short circuit. There are five discharge states of stable arc and unstable arc that are more perfect. Generally, there is ...
