ジャーナル フリーIn this report, outlined are the mechanical construction and its operative capability of the experimental apparatus which was prepared on a plan for a trial of electro-nozzling with the feeding operation.
Then, micro-holes were processed vertically on cobalt, with 5% solution of nitric acid used in consideration of its proved aptitude to meet the electrolytic characteristics of cobalt. Shown in the report are the program for this experiment, its results and the discussion thereon.抄録全体を表示PDF形式でダウンロード (2683K) -

ジャーナル フリーTooth profile used for watch or clock is formed with a part of circle and radius line, as the modified cycloid gear. The torque variation of gear positioned near the barrel gives the large influence on the accuracy of time-keeper. Therefore, the tooth profiles of these gears are determined from the view point of smooth torque transmission rather than from that of smooth rotation of gear.
The author has tried to get the tooth profile to make the transmitting torque constant, taking into account the friction arised from the sliding contact of teeth, and obtained such a profile from the theoretical considerations and compared it with the conventional profile.The tooth profiles and the error of the transmitted rotating angle are shown in diagrams.These diagrams will serve to determine the tooth profile of gear in the case where the small torque variation is required, for instance in the gear used for time-keeper positioned near the barrel.抄録全体を表示PDF形式でダウンロード (1255K) -

ジャーナル フリーAlloy steel (SNCM5) was cut with carbide tool S2 applying various cutting fluids and wear process on tool face (crater and flank wear) was observed. By observation of wear process, choicing standards for cutting fluids at high speed cutting were obtained. Those areas follows :
1) Lubricating property is more predominant for tool wear than cooling property.
2) Extreme pressure cutting oil is not good since it increases tool wear for its high chemical reaction.
3) Non water soluble oil is generally not good since it smokes very much though it has good lubricating property.
4) Concretely, recommended cutting fluids are emulsion type and soluble type.抄録全体を表示PDF形式でダウンロード (915K) -
