ジャーナル フリーSurface modification of titanium using EDM process was studied. To form a new titanium carbide (TiC) layer on the machined surface, finishing EDM process was examined. TiC layer with crack less surface was obtained in the relatively short discharge duration with low discharge current range under the electrode negative polarity.
And the various effective improvements in machined surface such as hardness, tribological properties and corrosion resistance were obtained respectively.抄録全体を表示PDF形式でダウンロード (6950K) -

ジャーナル フリーThe previous 2nd and 3rd reports described methods by which to improve the accuracy of the convex corner, corner R and large concave corner R on the rough cut of a workpiece, where the wire discharges symmetrically on front surface of the wire. The present paper describes methods by which to improve the accuracy of the concave corner having small radius corner R on the rough cut, where the wire discharges asymmetrically on the wire surface. A new method that combines the dwell operation method with the over cut method is proposed. The procedure and expressions used to calculate these control values based on a wire deflection model are described. In addition, the advantage of high wire tension is discussed. The proposed method was found to be useful for improving the concave corner accuracy and saving machining time.抄録全体を表示PDF形式でダウンロード (863K) -

ジャーナル フリーIn this paper, we propose a microcutting method with a reduced machining force by applying an electrolytic passive film formation on the workpiece surface. This process realizes the machining of microstructure such as 10μm wide micro grooves which has been difficult to be machined by conventional cutting. A mirror surface which has the roughness 30nm Ry is also obtained by this method.抄録全体を表示PDF形式でダウンロード (10910K) -
