Electroerosion machining system and method

The invention relates to an electroerosion machining system. The electroerosion machining system comprises an electrode for machining workpieces, a power supply for exciting the electrode and the workpieces to become opposite polarities, an electrolyte supply device for supplying electrolyte between the electrode and the workpieces, an operation device for moving the electrode corresponding to the workpieces, and a control device for controlling the operation device to move the electrode according to a machining path set by the control device for machining the workpieces layer by layer, determining the material volume of the workpieces removed by the electrode and the loss value of the electrode after the machining of one or more machined layers, dividing the following one or more machined layers into multiple machined blocks along the machining path, determining the volume of the machined blocks and compensating the loss of the electrode according to the removed material volume of the workpieces, the loss value of the electrode and the volume of the machined blocks. The invention further relates to an electroerosion machining method for compensating the loss of the electrode.
