Abstract
A numerical control system and method for controlling a travelling-wire EDM system in which the pulses from the numerical controller are transmitted to pulse motors driving the workpiece table along X and Y axes for generating the shape to be machined in the workpiece. A taper is applied to the cut by mounting one of the electrode wire guides on a support capable of x and y movements through respective pulse distributors and sign-changing inverters from the numerical controller with respective pulse motors so that the cut on one side of the workpiece represents the sum of increments from both the X-Y and x-y placements while the cut on the opposite side represents substantially only the increments of the X-Y displacements.
