Claim 0:
1. An online prediction method of tool-electrode consumption, adapted for an electrical discharge machining (EDM) apparatus, comprising:
an experimental design;
extracting electrode consumption variables from machining parameters of the electrical discharge machining (EDM) apparatus, wherein the electrode consumption variables comprise times of effective discharge, a machining depth, and accumulated machining time, the EDM apparatus has a main shaft and a tool-electrode disposed on the main shaft to perform electrical discharge machining on a workpiece through the tool-electrode,
obtaining a correlation between the machining parameters and the electrode consumption variables through a correlation analysis to establish a prediction model capable of predicting an effective contact area of a tool-electrode and the workpiece,
adjusting the machining parameters based on the predicted effective contact area, and
controlling the electrical discharge machining apparatus based on adjusted machining parameters.
