각광을 받고 있는 광통신 분야의 핵심부품인 페룰은 일본이 전 세계의 95%를 장악하고 있다. 국내에서도 일부 업체에서 양산을 하고 있으나, 핵심 연삭공정에 사용되는 연삭 가공장비는 전량 수입되고 있는 실정이다. 페룰은 0.1∼0.3$\mu\textrm{m}$의 동심도, ${\pm}$ 0.2$\mu\textrm{m}$의 외경치수, 0.1$\mu\textrm{m}$대의 진원도와 원통도, 10nm의 표면 거칠기를 구현해야 세계적 경쟁력을 갖출 수 있는 초미세, 초정밀 기계가공 부품이다.(중략)

As the optical communication industry is developed, the demand of optical communication part is increasing. ZrO$_2$ ceramic ferrule is very important part which can determines the transmission efficiency and information quality to connect the optical fibers. In general ZrO$_2$ ceramic ferrule is manufactured by grinding process because the demands precision is very high. And the co-axle grinding process of ZrO$_2$ ceramic ferrule is to make its concentricity all of uniform before centerless grinding. This paper deals with the analysis of the process parameters such as grinding wheel speed, grinding feedrate and regulating wheel speed as influential factors, on the concentricity and surface finish developed based on Taguchi's experimental design methods. Taguchi s tools such as orthogonal array, signal-to-noise ratio, factor effect analysis, etc. have been used for this purpose optimal condition has been found out. Thus, if possible be finding highly efficient and quality grinding conditions.
