Predictive modeling of surface roughness and material removal In powder blasting of glass by design of experiments

파우더 블라스팅을 이용한 유리 가공시 실험계획법에 의한 가공면 분석

The old technique of sandblasting which has been used for paint or scale removing, deburring, and glass decorating has recently been developed into a powder blasting technique for brittle materials, capable of producing micro structures larger than 100um. A large number of Investigations on the abrasive jet machining with output parameters as material removal rate, penetrate and surface finish have been carried out and reported by various authors. In this paper, we investigated the effect of surface characteristics and surface shape of the abrasive jet machined glass surface under different blasting parameter. and finally we established a model for abrasive flow machining process, and compared with experimental results.
