A Study on Deburring Inconel 718 Using Water Jet Technology

One of the most significant problems encountered in machining is that of burr formation. All edges must be completely defect-free, with generous radius, for operational, safety and aesthetic reasons. The machining operation or CNC grinding process that shapes the component produces burrs and sharp edges. The deburring process is intended to remove these imperfections and produce specific edge profiles. Disadvantages of manual deburring methods include the cost of labor, time taken to deburr the component, quality and health and safety issues. A promising method for deburring is the use of water jet technology. Water jet machining is now providing a simple and economical approach to selectively removing burrs from areas that are difficult to access with consistent results and absolute uniformity. This paper is aimed at evaluating the process of water jet deburring of Inconel 718. Trials conducted to study the effect of water jet deburring process proved to be effective.
