摘要： In an electric discharge machine, wherein electric power is supplied between an electrode and a workpiece to machine the workpiece, a jumping motion is performed to temporarily increase a distance between the electrode and the workpiece. The electric discharge machine includes a detector for detecting a machining reaction force; a setting unit for setting a specified value of the machining reaction force; a comparator for comparing a detected value of the machining reaction force with a specified value of the machining reaction force; and a changing unit for changing a locus of the jumping motion so that the machining reaction force can be reduced if the comparator finds that the detected value of the machining reaction force is greater than the specified value of the machining reaction force.

摘要： A surface treating is performed by an electric discharge. The electric discharge is generated by applying a voltage between an electrode and a metal workpiece. The electrode is a solid or green compact electrode or the like which is made of a reforming material. The workpiece may be an end mill or the like. Then, a coating layer is formed on a surface of the metal workpiece. Thereafter, a nitriding treatment is performed on the coating layer in a nitriding vessel or the like. Thus, a hard coating layer of better quality is formed on the surface of the workpiece whether a material of the workpiece is steel or hard metal.
