In this study, consists of ceramic compounds for characteristics experiment on the electromotive force and resistance by temperature change of manganese oxide. The test results, the resistance drastic decrease in temperature from 40 to 50℃. Temperature-resistance characteristics of manganese oxide was able to application in the defense industry and civilian industry on the development of fire detection line. It is helpful to development of a fire detection sensors in high-temperature 100-1000℃ environments, high humidity, high vibration motion and harsh environment.
TiAIN 코팅 엔드밀공구 R-Curve 가공시 절삭력이 공구에 미치는 영향
김원중(Won Jung Kim),백용하(Yong Ha Baek) 산업기술교육훈련학회 2010 산업기술연구논문지 (JITR) Vol.15 No.4
It is the required of high precision and high efficiency machining process for most of the mechanical and electronic parts along with the rapid development of modern industry. Necessity of efficient R-curve processing is rising in the machine and parts industry of electronics industry and troy industry field. In machining experimentation the results of R-curve, When spindle speed 25,000 rpm and feed rate 2,000mm/min and depth of cut 0.lmm, it was shown the best result as surface roughness. also, When R-curve machining, it is analyzed that it is affected in tool wear in increase of spindle speed and Cutting force and depth of cut.
