Effect of the Number of Nozzle Scanning in Micro-Line Grooving of Glass by Powder Blasting

Powder Blasting을 이용한 유리의 미세 선형 홈 가공시 노즐 주사 횟수의 영향

The old technique of sandblasting which has been used for decoration of glass surface has recently been developed into a powder blasting technique for various materials, capable of producing micro structures larger than 100 m. This paper describes the performance of powder blasting technique in micro-line grooving of glass and the effect of the number of nozzle scanning on the depth and width of line groove. Experimental results showed that increasing the no. of nozzle scanning resulted in the increase of depth and width in grooves. Increase of width which may cause several problems in the precision machining results from wear of mask film.
