Fundamental research of stress analysis in cutting tool by means of caustics method. In case of wedge shaped plane with uniformly distributing load
Autor: Hajime Kurita, Takeshi Kitagawa, Kiyoshi Isogimi
Publikováno v: Journal of the Japan Society for Precision Engineering. 54:390-395
In this paper the fundamental investigations are performed to measure the stresses at the cutting edge and to analyze the occurring mechanism of initial damage. Under the simplified two dimensional cutting condition, the object of study is wedge shap

Fatigue strength of machined screw thread. Effects of loading modes in fatigue test
Autor: Kiyoshi Isogimi, Hajime Kurita
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 53:2640-2644
The effects of various kinds of factors on the fatigue strength of machined screw thread connection generally used as the fastener of machine components are examined. Effects of materials (i. e. heat-treatment), fastening force, yielding pre-tension

Effects of Interrupted Cutting on the Life of Sinitered Carbide Tools
Autor: Hajime Kurita
Publikováno v: Journal of the Japan Society of Precision Engineering. 31:849-857
The life and the final failure of the carbide cutting edge in the interrupted cutting when turning steel is ascertained experimentally in this paper, and these results are examined also by comparison with the life and the final failure of the cutting

On the 'Digging in' of Cutting Tool
Autor: Hajime Kurita, Shizuo Doi
Publikováno v: Transactions of the Japan Society of Mechanical Engineers. 20:55-60
If there are some insufficient factors in the metal cutting operation, it may happen that the cutting edge of the tool digs suddenly into work and the work is damaged. The so-called "digging" may be classified into two types according to the cause. O

Effects of Chatter Vibrations on the Life of Sintered Carbide Tools (1st Report)
Autor: Hajime Kurita
Publikováno v: Journal of the Japan Society of Precision Engineering. 31:321-326
The life and the final failure of the carbide cutting edge in the machining without chatter are examined firstly in this paper to ascertain the effects of chatter vibrations on the life of carbide tools. It is consequently ascertained that in the mac
