Investigation on Micro-abrasive Jet Machining: Machinability Study
Micro-Abrasive Jet Machining (µ-AJM) is an advanced mechanical micromachining process used to machine various engineering materials - brittle and ductile. The paper presents a study on machinability of brittle material as Sodalime glass and Quartz glass and ductile material as Polymethyl Methacrylate (PMMA) through µ-AJM. Three different commercial abrasives – Aluminium Oxide (Al2O3), Silicon Carbide (SiC), and Synthetic Diamond (C) of has been employed to impact three different workpiece materials. Machinability of materials after different abrasives impact is compared in terms of Material Removal Rate (MRR) and surface morphology. The study revealed that the type of abrasive and their hardness along with the fracture toughness of the workpiece are significant factors determining the machinability of workpiece material in µ-AJM. Synthetic Diamond abrasive gives maximum material removal rate irrespective of workpiece materials used whereas the best surface morphology is obtained with Aluminium Oxide abrasive.
