Electrochemical Curved Hole Machining with Electrode Posture Control System
Almost holes such as cooling channels of a mold or hydraulic equipments are machined by drilling process. It is desirable to establish a cooling channel located within a constant distance along a curved surface of a cavity or a core. However, the drilling process cannot make curved holes. Therefore...

| Summary: | Almost holes such as cooling channels of a mold or hydraulic equipments are machined by drilling process. It is desirable to establish a cooling channel located within a constant distance along a curved surface of a cavity or a core. However, the drilling process cannot make curved holes. Therefore a curved hole machining technique is required. Some kinds of curved holes machining process have been proposed, but they have not reached the practical level. The objective of this study is to develop a curved hole processing method using the electrochemical machining with an electrode posture control system. The posture of an electrode is controlled with a stepping motor and the wire. A simulation technique to predict the electrode position in a hole and the hole path was also developed. It was shown that the proposed system is able to make curved holes with the reasonable efficiency and accuracy. |
