Abstract
An electroerosion machining system comprises an electrode, a power supply, an electrolyte supply, an electroerosion controller connected to and monitoring the power supply, and a working apparatus configured to move the electrode relative to the workpiece. The electroerosion machining system further comprises a CNC controller configured to cooperate with the electroerosion controller to control the working apparatus, and to calculate a wear value of the electrode. Further, the CNC controller is configured to segment the toolpath of every layer into a plurality of segments, and to divide the compensation value for every layer to be machined into a plurality of value segments, and further to use the value segments to compensate for electrode wear along the respective toolpath segments during machining of the workpiece. An electroerosion machining method is also presented.
