摘要:
Example electrochemical machining systems and methods for machining a surface of a sample. In particular, the system includes a nozzle configured to dispense a jet of an electrolyte solution towards the surface of the sample. A position or orientation of the nozzle can be controlled to direct the jet of the electrolyte solution from the nozzle towards an area of the surface of the sample (e.g., an area for electrochemical etching or other surface treatment). The electrochemical machining is performed by application of a charge to the nozzle and apply a charge to the sample (e.g., grounding or other charge return path), such that the nozzle and the sample define first and second electrodes of an electrolytic cell, electrically connected by the jet of electrolyte solution.

A method of assembling an airfoil includes depositing a bonding material on a first end of the tip portion and shaping the bonding material to form a first plurality of features. The first plurality of features correspond to a second plurality of features on a second end of the body portion. The method also includes positioning the first end relative to the second end such that the first plurality of features and the second plurality of features interlock. The method further includes coupling the first end of the tip portion to the second end of the body portion.

A wire electric discharge machine according to invention prevents occurrence of failure beforehand and prevents machining stop. This can be effected by acquiring an image of a part using an image information collection unit such as a visual sensor with respect to matters, which requires inspection management of the amount of a wire accumulated in a wire electrode storage box, a remaining amount of a wire of a wire bobbin, a level of a machining liquid of a water reservoir and the like, and issuing warning when it is determined, based on the obtained image information, that the failure is highly likely to occur as the wire deposition amount is close to a limit of the wire electrode storage box, the wire remaining amount is small, or the machining liquid level falls below a set value to deal with the state based on this warning.

In an electrical discharge machine that applies a voltage between an electrode and a workpiece to generate electrical discharge, an electrode holder holds the electrode. An ultrasonic motor has a fingertip that comes into contact with electrode holder, and moves electrode holder in a driving direction by moving the fingertip in an annular manner at an ultrasonic-range frequency. A roller bearing guides the movement of the electrode holder in the driving direction. A control circuit controls a position of the electrode in the driving direction by driving the ultrasonic motor, and moves the electrode holder based on an abnormality occurring in resistance against the movement of the electrode holder in the driving direction such that the electrode holder is moved by a movement distance equivalent to when the largest roller element among a plurality of roller elements of the roller bearing rolls and rotates once without sliding or longer.

The present invention provides a continuous machining system and the machining method thereof. The machining system comprises a feeding module, an electrochemical machining module, and a separating module. The feeding module supplies a material strip continuously; the electrochemical machining module performs an electrochemical machining to the material strip. When the feeding module supplies the material strip to the electrochemical machining module continuously, the electrochemical machining module performs the electrochemical machining to the material strip continuously for forming continuously a plurality of components on the material strip. The separating module separates the plurality of components from the material strip. Thereby, the machining time is saved, and thus achieving the purposes of continuous machining and mass production.

The automatic wire-threading device includes a wire feed motor that drives a wire feed roller in a feeding direction, a wire-feed-motor control unit that outputs a feeding-direction rotation-speed reference to the wire feed motor at a time of a threading operation of a wire electrode and that reduces torque in a feeding direction when a detected rotation speed of the wire feed roller is larger than the feeding-direction rotation-speed reference, a wire collecting motor that drives a wire collecting roller in a collecting direction, and a wire-collecting-motor control unit that outputs a predetermined wire-collecting-roller speed reference to the wire collecting motor to collect a wire. The wire-feed-motor control unit limits torque so that an absolute value of motor torque in a winding-back direction of a wire feed roller is smaller than an absolute value of motor torque in a feeding direction.
