The present invention relates to a method for measuring metal ion permeability of a polymer film, comprising the steps of: applying a voltage to the polymer film at a temperature of 5 C. to 250 C., while one side of the polymer film is brought into contact with an electrolyte comprising metal ions, an organic solvent and an aqueous solvent; and measuring the change rate of resistance or change rate of current of the polymer film according to time, after the voltage is applied, and a device for measuring metal ion permeability of a polymer film used therefor.

A wire electrical discharge machine recognizes that the finished piece (core) has been separated from the piece of work as a result of electrical discharge machining, allows fluid to be jetted against the finished piece (core) from the lower nozzle so that the finished piece (core) floats upward, recognizes that the finished piece (core) has floated upward by a predetermined amount on the basis of the completion of the process program or the information gained from the sensor, and allows the core removal unit to catch the finished piece (core) for removal and collection after it has been recognized that the finished piece (core) has floated upward by the predetermined amount.

An apparatus for an electrochemical discharge machining process is provided. The apparatus includes a holder housing having, an inlet hole, an outlet hole, a first side, and a second side, and containing an electrolyte, a tool holder disposed at the first side, and a first electrode having a first end and a second end. The holder housing is configured to sealingly accommodate the electrolyte unless at least one of the inlet hole and the outlet hole is open. The first end is coupled to the tool holder and the second end passes through the second side. Since the apparatus is moved to a machining position of the work-piece by a worker, additional power for controlling the position thereof is not necessary. In addition, the apparatus is easy to carry and use because of its simple structure.
