摘要： A technique of removing material from metal parts referred to as OPECM and a corresponding OPECM processing machine are disclosed. A tool electrode is manufactured for removing material from a target workpiece, and the workpiece and tool electrode are fixed into a processing machine that imparts an oscillatory motion path or profile and applies a voltage through a flowing electrolyte solution. The disclosed technique and processing machine removes material from the surface of the target workpiece through proximal surface dissolution as the workpiece and tool electrode are brought within proximity of one another.

摘要： A wire electric discharge machine includes a machine learning device that learns an adjustment of an axis feed command of the wire electric discharge machine. The machine learning device determines an adjustment amount of the axis feed command by using data related to a movement state of an axis, and adjusts the axis feed command based on the determined adjustment amount of the axis feed command. Subsequently, the machine learning device performs machine learning of the adjustment of the axis feed command based on the determined adjustment amount of the axis feed command, the data related to the movement state of the axis, and a reward calculated based on the data related to the movement state of the axis.

摘要： A method of improving an internal surface topography of a manufactured workpiece includes filling a workpiece with an electrically conductive magnetorheological (MR) fluid. The workpiece includes at least one internal feature having an inner surface with at least one irregularity. The method further includes converting the MR fluid into a rigid MR material, applying a voltage to the rigid MR material, and ablating the inner surface in response to the voltage to remove the at least one irregularity.

摘要： An electrochemical machining apparatus being capable of performing multiple points and multiple angles machining is provided. The electrochemical machining apparatus includes at least one electrode member, a guiding member and an actuation member. The electrode member includes a conductive end and a free end, wherein the electrode member is rigid and unbendable. The guiding member is for limiting and guiding the electrode member to move. The actuation member is for exerting a force to the free end of the electrode member, thereby enabling the conductive end of the electrode member to form angle variations. A force-exerting direction from the actuation member to the free end is parallel to a central axis of the electrode member or deflects off the central axis so as to form the angle variations.
