Abstract
Micro abrasive jet machining process is an advanced micro blasting technique commonly used for cutting and drilling of brittle materials. The machining is based on the brittle fracture produced by the high velocity abrasives. Micro Abrasive Jet Machining (AJM) is capable of material removal at micro scale, but at the same time the expelled abrasives can cause environmental hazards. Inhaling of these abrasives can cause various health problems to the person operating the setup. Current work mainly focuses on how the behavior of machining changes by incorporating a liquid film during AJM process. Experiments are conducted by varying input parameters such as mass flow rate, standoff distance, motor speed and liquid film thickness. The corresponding responses in the output parameters such as Material Removal Rate, Radial Overcut and Area of Frosted Zone are evaluated. The process parameters are optimized using Genetic Algorithm (GA) in current work.
