Modern CNC controllers for EDM allow loading of a table of predefined cutting speeds for each cut of the wire along the contour into the controller. During the machining process, data from the table is selected by specifying a special code of cutting speeds.
SprutCAM support such representation of cutting conditions in its erosion operations. Depending on the thickness and the material of the work piece, the material and the diameter of the wire, the required surface smoothness of the part it is possible to select cutting speed, wire offset value (allowance, individual for each cut and taking into account the wire radius, burnouts, depending on the power of the electric spark, etc.) and other parameters separately for each cut.
The tables of machining conditions can either be selected from special cutting data libraries or updated in each operation manually.
