Abstract
ABRASIVE JET MACHINE presents the working of machining and removing materials from the brittle and heat sensitive materials by the application of high speed stream of abrasive particles carried by air through the nozzle. In particular drilling of holes of minimum diameter and maximum depth is also possible in this machine with greater accuracy and surface finish. Since no heat is induced while machining the surface, the workplace is not subjected to thermal shocks. Tumbling machining apparatus is used for determining the material removal rate (MRR) for materials like glass, ceramics and aluminium sheet by varying the parameters like pressure, nozzle tip distance (NTD), type of abrasive and its flow rate. In this project we have designed and fabricated the tumbling machining apparatus for removing unwanted material, drilling holes and cutting glass, ceramic plates and aluminium sheet.
