Abrasive Water Jet Machining – The Review
Abrasive water jet machining (AWJM) is a relatively new machining technique. Abrasive Water Jet Machining is extensively used in many industrial applications. AWJM is a nonconventional machining process where material is removed by impact erosion of high pressure high velocity of water and entrained high velocity of grit abrasives on a work piece. There are so many process parameter affect quality of machined surface cut by AWJM. Important process parameters which mainly affect the quality of cutting are traverse speed, hydraulic pressure, stand of distance, abrasive flow rate and types of abrasive. Important quality parameters in AWJM are Material Removal Rate (MRR), Surface Roughness (SR), kerf width, tapering of kerf. This paper reviews the research work carried out so far in the area AWJM.
INVESTIGATION ON WATER JET ABRASIVE MACHINING DURING CUTTING OF CERAMIC TILE
In this paper, production of ceramic tiles by using waste raw material egg shells and sea shells additives was investigated. The egg shells and sea shells is regarded as a suitable raw material for ceramic tile production because of its physical properties and chemical composition. It’s provide high strength to the bonding of ceramic tile. Abrasive water jet cutting is a non-traditional machining method that offers a productive alternative to conventional techniques. It uses a fine jet of ultra-high pressure water and abrasive slurry to cut the target material by means of erosion. This thesis attempts to investigate kerf width and material removal rate in abrasive water jet machining of ceramic composite material tiles which is having wide applications in domestic, commercial and industrial construction work. Three different process parameters were undertaken for this study; water pressure, standoff distance and abrasive flow rate. Experiments were conducted Design of Experiment using Taguchi’s design analysis by MiniTab17. Keyword: AWJ, Taguchi, Water pressure, Standoff distance, Abrasive flow rate
