Abstract: A wire electric discharge machine corrects a machining route according to an angle between two moving blocks that form a corner portion. A correction distance and a return distance are computed based on a detected corner angle. The correction is implemented so that an end point of a block to be machined first is extended according to the correction distance, and a portion extending from a start point of a block to be machined subsequently to an intermediate point of this block is removed according to the return distance. A machining route is created so that the end point of the new block created by the extension is connected to the start point of the other block created by the removal, and the wire electrode is moved along the machining route relative to a workpiece.

Abstract: Layered metal deposition by fusion thereof onto a surface of an engineered structural member, without degrading structural performance. The net shape of an exterior member is defined, including a fusion contact area. The structural member is preheated below its maximum operating temperature. An energy beam and feedstock are directed to a feed point in the fusion area, thereby forming a molten puddle fusing the materials together. The feed point is moved relative to the structural member, thereby advancing the molten puddle of presently fed feedstock and rapidly solidifying previously fed feedstock. The energy beam power is modulated to control the size of the molten puddle so as not to exceed a predetermined depth of penetration of the fusion region into the structural member. Advancing the feed point sequentially fuses feedstock into the defined net shape on the structural member.

Abstract: An electrode-supporting assembly for a contact-start plasma arc torch has an insulator that partially houses an electrode, and employs a spring-loaded plunger to bias the electrode to a forward position. The spring is engaged between the plunger and a contact element attached to the insulator, and may conduct electrical current to the electrode. The plunger, spring, and contact element are retained in the insulator when the torch is opened to replace the electrode, which is a consumable part. The electrode and the plunger have axially-engagable mating surfaces to assure good thermal and electrical conductivity therebetween. Conductivity can be further enhanced by forming the plunger of silver or a silver-bearing alloy. In some embodiments, a passage through the insulator is partitioned into forward and rear chambers, with the plunger, spring, and contact element trapped in the rear chamber.
