Development of a Three Axis controlled Fast Tool Servo for Ultra Precision Machining (1st Report)
Autor: Keiichi Nakamoto, Masayuki Takahashi, Toshimichi Moriwaki, Toshihiko Wada
Publikováno v: Journal of the Japan Society for Precision Engineering. 73:1345-1349
A new three-axis FTS system has been developed for ulrtaprecision machining. The 3-axis FTS unit can drive the cutting tool freely in the space by controlling the motion of the three piezoelectric actuators arranged along the three axes of the orthog

Fabrication of (SrxK0.5-xNa0.5-x)NbO3Pizoelectric Ceramics and Effects of MnO Addition on Their Piezoelectric Properties
Autor: Toshihiko Wada, Shinjiro Tashiro, Keisuke Ishii
Publikováno v: Japanese Journal of Applied Physics. 45:7449-7454
Piezoelectric properties were investigated in (K,Na)NbO3 ceramics whose K and Na were substituted with Sr at 1 to 5 mol % to rearize high piezoelectric properties. The maximum piezoelectricity was obtained in the sample with 3 mol % Sr substitution.

Study on Micro-ECM with Short Pulses
Autor: Takayuki Abe, Takahisa Masuzawa, Takeshi Masaki, Toshihiko Wada
Publikováno v: Denki Kako Gakkaishi. 40:29-35
Electrochemical machining (ECM) has the advantage that it can quickly produce mirrorlike surfaces without causing any additional damage and stress on the workpiece surface. However, it has a limit in machining accuracy in the machining of microshapes

FEM Simulation of Non-Uniform Shrikage and Prediction of Fracture in Sintering of Graded Laminated Powder Compact
Autor: Toshihiko Wada, Ken-ichiro Mori, Kozo Osakada
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 65:779-785
Non-uniform shrinkage in sintering of graded laminated powder compacts is simulated by a viscoplastic finite element method to predict the shapes of the sintered products. Since the component of the compact grades in the thickness direction, the sint
