In addition, the apparatus measures a machining depth at each interval period of inline measurement. The apparatus also computes machining parameters such as a machining depth for each machining pass, a number of remaining passes of machining which are to be executed, and also increments an outline offset according to the measured machining depth. An electrode position control then provides positional control of a tool electrode according to the computed machining parameters.

摘要： A surface treatment method and apparatus therefor for providing wear and corrosion resistance, which includes relatively rotating a modified metallic member to be surface modified and a block, which may be metal only or may include a modifying material (e.g., ceramic or W-C/Co), and generating electrical discharge between the block and the modified metallic member to form a modification layer on the surface of said modified metallic member. If the modifying material is not in the block, it can be supplied via a dielectric bath or spray at the discharge interface. In this manner, the cutting edges of a cutting tool with a complicated shape can be surface modified easily to carry out tool surface treatment which increases a cutting tool life greatly. Cutting and surface treatment can be performed alternately as determined by a controller.

摘要： A wire-type electric discharge machining apparatus capable of attracting material from a workpiece to an integral electromagnet. An aperture is located proximate the electromagnet. When material is attracted by the electromagnet, the aperture will be obstructed. Attraction is confirmed by measuring the pressure in a chamber in communication with the aperture, such that a low pressure indicates obstruction, and thus attraction of the material to the electromagnet. If based on this measurement it appears that the material has not been attracted to the electromagnet, a further attempt is made at a different location of attraction.
