Ceramics의 被削性에 관한 硏究 : 低純度 AL-Ceramics의 切削 Machining of Low Purity Alumina Ceramics = A Study of Machinability of Ceramics

다국어 초록 (Multilingual Abstract)

In this Study, unsintered, presintered and sintered low purity Alumina Ceramics were machined with various tools to clarify the machinability, the optimum tool materials and the optimum tool materials and the optimum cutting conditions. The main conclusions obtained were as follows.
(1) In the case of Carbide tool KO1, the tool life in machining white body was the longest, and the machinability of pre-sintered Ceramics becomes poorer with the increase of the pre-sintering temperature.
(2) In machining the low temperature pre-sintered Ceramics, the tool life increases with the increase of feed rate and clearance angle, and with the decrease of rake angle.
(3) When the pre-sintered Ceramics were wet machined with sintered diamond tool, the tool life becomes extermely long, and higher cutting sped be used than in the case of full-sintered Ceramics. The productivity of wet cutting is much higher than that of dry cutting.
