An Economically Viable Abrasive Jet Machine's Design And Construction

Abstract

Abrasive blasting techniques include abrasive jet machining (AJM), often referred to as abrasive micro-blasting, pencil blasting, and micro-abrasive blasting. In both processes, the material is eroded from the workpiece by the abrasive traveling with the high-speed gas. Cutting, heat-sensitive, brittle, thin, or hard materials are among the several applications for these machining processes. It is mostly used to cut intricate shapes or create various edge shapes. The method of removing material from a particular workpiece using high jet velocity abrasive particles combined with a gas medium from a nozzle is known as abrasive jet machining, or AJM. Erosion is the primary cause of the material removal in this process. Cutting shapes, drilling holes, and deburring hard, brittle materials like glass are the primary applications for AJM. The machine, which mostly employs readily available materials like mild steel, aluminum sheet, and glass fiber, was constructed in the institute workshop using a variety of machine equipment, including a hand drill, an arc welding machine, and a grinding machine.

By using fewer manufactured components, the machine's performance has been reduced to a minimum. Abrasive draining system, machining chamber, work holding device, compressor, nozzle, filter and regulator, and mixing chamber are some of the different parts of AJM. The machine must be automated with a microcontroller, stepper motor, and drive arrangement in order to move in three directions. We have decided to use these various components after doing the proper design calculations.
