This report describes a newly developed compensation-method for the electrode-deformation in contouring electric discharge machining with cylindrical electrode. The compensation value is predictively calculated by using self-learning algorithm and the data measured during the machining process. Based on the calculated value, compensation cut is given progressively between the measuring points. When the accuracy of prediction is sufficiently high, the interval between measuring points is extended. In order to confirm this algorithm, computer simulations are executed using several practical machining-data which were previously measured for horizontal plane, inclined plane and hemisphere machining. Main results are as follows : (1) Accuracy of prediction is within 10μm except for few cases including large fluctuation. (2) Compensation-modulus is improved more than double compared with that obtained by the conventional method.
