for the mold of PDP barrier rib Nam-Hun Kim*, Eun-Sang Lee**, Deug-Woo Lee*** * Department of Mechanical and Precision Engineering, Pusan National University, Busan, Korea ** Mechanical Engineering Division, Inha University, Incheon, Korea *** Mechanical Engineering Division, Pusan National University, Busan, Korea Abstract This paper describes the machining characteristics of developed micro grooving machine. Experiments have been conducted on the various grooving condition such as spindle revolution speed, infeed rates and depth of groove with a blade designed according to the shape of groove. And acoustic emission (AE) sensor was examined by the in-process monitoring of groove machining. As a result, this study represented optimized grooving condition and possibility of application of AE technique in groove machining.
