EDM technique of curved-hole using a metal ball electrode suspended with a copper wire was proposed in this report. By EDM using a copper-tungsten ball of 5.5mm in diameter suspended with cupper wire, the straight hole over 30mm in depth could be drilled into a steel workpiece at a constant machining rate. The electrode ball always vibrated during the process by the impact force associated with sparks, which would results in smoother exclusion of debris. Also, the machining of bended-hole was attempted by varying the tilt angle of the workpiece, and the hole with the bending angle up to 45° could be easy obtained. Moreover, by repeating the machinings of bended-hole, multiple curved holes could be machined by this method.

In this paper, forty-wire electrical discharge machining and multi-wire EDM phenomenon are investigated. In a standpoint of science, multi-wire EDM phenomenon is unexplained. To solve this problem, we observed parallel electrical discharge phenomenon between a wire electrode and a workpiece via high-speed camera. With the aim of productivity improvement of SiC wafers, forty-wire EDM was applied for silicon carbide material which is 100 mm thick. we successfully obtained the average ditch width of 208 µm for forty ditches.

For the variation of the experimental data due to thermal expansion, the affection of depth of cut by heat expansion cannot be ignored in experiments under infeed grinding on the surface grinder. Then work pieces on the balance type device are ground with constant pressure load for the measurement of stable experimental data. Grinding experiments using CBN wheel and four types of grinding fluid are considered on grinding titanium in association with the environmental grinding technology. The results of experiment indicate that the plant oil-based grinding fluid has a good grinderbility using CBN wheel on specific Grinding Energies. Although there are two types in metalworking fluid non-water-soluble which are the plant oil and the mineral oil, in this experiment the vegetable oil is only used. From now for environmental grinding technology, it is need the next comparative experiment with mineral oil. In addition, and this experiment will be done for getting the mirror surface of titanium which is ground with CBN wheel dressed to flat the tip of abrasive grains.

Although the log-aesthetic curves are expressed only by an integral form of the tangent vector, it is possible to interactively generate and deform them and they are expected to be utilized for practical use of industrial and graphical design. In this paper we propose a new method to solve the G2 Hermite interpolation problem with the log-aesthetic plane curve as well as a method to generate an S-shaped curve for G1 Hermite interpolation. The methods proposed in the paper have been implemented as a plug-in module for a commercial CAD system and are successfully used for practical design.

Since a semiconductor laser has high conversion efficiency, it has many expectations for effective application. The application trial of processing at an actual factory and spot of processing is increasing. Moreover, it can be used now as a heat source which can carry out processing directly. It is called DDL (Direct Laser Diode). However, since there is almost no information about the structure of DDL, the literature theoretically treated in this heat source is not found. That is considered to have interfered of the broad application for development. The purpose of this study is establishment of the theoretical approach for the semiconductor heat source and simulation for processing.
