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 100㎛. In this paper, we studied on the predictive modeling of material removal and surface roughness μ in powder blasting of glass by design of experiments. The surface characteristics and surface shape of powder blasted glass surface were tested under different blasting parameter. Finally, we proposed a predictive model for powder blasting process, and compared with experimental results.

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.

Powder blasting process has become an important machining technique for the cost effective fabrication of micro devices. This process is similar to the sand blasting, and effectively removes hard and brittle materials. A large number of investigations on the abrasive jet machining with output parameters as material removal rate, penetrate and surface roughness have been carried out and reported by various authors. To achieve higher surface roughness, To increase material removal rate, and to identify the influence of blasting parameters on the output parameters, we use taguchi method which is one of design methods of experiments. So we can select process parameters to optimize the blasting process of glass. From the experiments verification tests, it is found that the taguchi method is useful as a robust design methodology for the powder blasting process.

Powder blasting technique has been considered one of the most appropriate micro machining methods for hard and brittle materials, since the productivity is high and the heat layers caused by material removal are very thin. Recent development of special purposed parts, such as the parts for semiconductor processing, the parts for LCD, sensors for micro machine fabrication and so on, has been expanded. Thus, it is essential to develop powder blasting technologies for micromachining of hard and brittle materials such as glass, ceramics and so on. In this paper, the characteristics of powder blasted glass surface were tested under various blasting parameters. Finally, we proposed a predictive model for powder blasting process using the neural network and the response surface method. Detail analysis of the simulation results is carried out and the performance of two predictive models is compared.
