Application of Taguchi & Response Surface methodology in Optimization for Machining of Ceramics with Abrasive Jet Machining

Abstract

Abrasive jet machining also known as micro-abrasive blasting or pencil blasting is a non-traditional machining process in which the metal removal takes place due to high velocity abrasive particles. The abrasive particles are propelled by high velocity carrier gas (commonly air). This process is specially used for edge shapes and intricate shapes. The metal cutting or drilling is performed due to high impact of abrasive particles on the work surface. This machining technology proves good results when tool life is taken into consideration, given the fact that the abrasive material can be reused several times before abrasive particles lose their cutting effect. It is already proved that this technique is effectively adopted for polishing and deburring processes. The present study highlights the influence of different parameters of Abrasive jet machining like Pressure, SOD, Abrasive Flow Rate, on the Metal removal and Kerf width on Ceramic Tiles, the type of abrasive particle used for this experiments is Al2O3. The experiments are conducted according to TAGUCHI method of L9 orthogonal array and RSM, latter compared with the Results of ANOVA using STATGRAPHICS.
