Fabrication of abrasive jet machine
2013Co-Authors: Shatabdi BiswalAbstract:Abrasive Jet Machining (AJM) is the process of material removal from a work piece by the application of a high speed stream of abrasive particles suspended in a gas medium from a nozzle. The material removal process is mainly caused by brittle fracture by impingement and then by erosion. The AJM will chiefly be used to cut shapes, drill holes and de-burr in hard and brittle materials like glass, ceramics etc. In this project, a model of the Abrasive Jet Machine was designed using CAD packages like AutoCAD and CATIA. Care was taken to efficiently use the available material and space. The machine was fabricated in the institute workshop with convectional machine tools like arc welding machine, hand drill, grinding machine using commonly available materials like mild steel sheet and rod, aluminum sheet, glue, polythene sheet ,glass fiber which are commonly available in the local market. Care has been taken to use less fabricated components, because, the lack of accuracy in fabricated components would lead to a reduced performance of the machine. The machine was be automated to have 3 axes travel using microcontroller and driver arrangement along with stepper motor. The different functional components of AJM are the Machining Chamber, work holding device, abrasive drainage system, compressor, air filter and regulator, abrasive nozzle, and mixing Chamber with cam motor arrangement. The different components are selected after appropriate design calculations.

Development of Electrochemical Machining System in Ultrapure Water and Application to Planarization Machining Process.
Journal of the Japan Society for Precision Engineering, 2002Co-Authors: Yuzo Mori, Hidekazu Goto, Kikuji Hirose, Yasushi Toma, Itsuki Kobata, Kenichi MoritaAbstract:An electrochemical Machining system using ultrapure water has been developed, designed for planarization Machining and free-curvature-shape Machining. The Machining system is composed of three units: an electrochemical Machining apparatus, an ultrapure water refining and circulation unit, and a high-pressure ultrapure water supply unit. The Machining apparatus is equipped with an XYθ table and a Zφ Machining electrode. A cylindrical or a spherical electrode is used for the Machining electrode. The Machining Chamber is continually filled with refined ultrapure water by the refining and circulation unit. During Machining experiments, process by-products, bubbles, and the like around the Machining point can be efficiently removed by the high-pressure ultrapure water supply unit. Using this Machining system, planarization experiments have been performed on copper plates, which are known to be easily etched, via application of a positive voltage. The effects of various Machining parameters (current density, rotating speed of the electrode, etc.) on the roughness of the etched surface are investigated. It was found that the use of a high-pressure ultrapure water supply nozzle is effective in the planarization process. Furthermore, it was also found that there is an ideal set of conditions with respect to the combination of current density and rotating speed of the electrode. Copper plate surface roughness (Ra) was successfully reduced from 164 nm to 10 nm by planarization Machining, with the optimal set of parameters.
