摘要： A machining system for electromachining a workpiece that in one embodiment includes a machine tool, a cutting tool for performing the eletromachining, and a tool holding apparatus for conductively holding the cutting tool and coupled to the machine tool. The tool holding apparatus includes a holding element for holding the cutting tool and at least one solution releasing element. The solution releasing element is used to receive machining solution and release the machining solution onto a predetermined area of the cutting tool through at least one group of channels. Each group of channels includes at least two channels configured to respectively release the machining solution onto at least two adjacent sections in the predetermined area of the cutting tool.

摘要： An electrical machining method comprises machining a workpiece by an electrical machining device comprising an electrode; increasing a feedrate of the electrode at a first acceleration if a discharge current passing through the electrode and the workpiece is lower than a discharge current reference; and decreasing the feedrate of the electrode at a second acceleration if the discharge current is higher than the discharge current reference, wherein the second acceleration has an absolute value higher than that of the first acceleration.

摘要： An apparatus for electrically machining including a rotatable shaft and an electrode for electrically machining is disclosed. The electrode is movably connected to the rotatable shaft. When the rotatable shaft is rotated, the electrode rotates together with the rotatable shaft and moves relative to the rotatable shaft under an action of centrifugal force. Further disclosed is a method for electrically machining including: movably connecting an electrode to a rotatable shaft; inserting the rotatable shaft into a hole in a workpiece, and keeping a gap between the electrode and the workpiece, wherein the hole has a first diameter; powering on the electrode and the workpiece; rotating the rotatable shaft in the hole to generate centrifugal force; and pushing the electrode relative to the rotatable shaft towards the workpiece under an action of the centrifugal force to remove a portion of a material of the hole.
