Abstract
Present work discusses the method of machining and characterization of blind pockets on Ti-6Al-4V alloy fabricated using Abrasive water jet machining (AWJM) by varying the process parameters; pressure, stand-off distance (SOD) and abrasive size. Depth of pockets was measured by coordinate measuring machine (CMM). Deeper pocket were formed at higher pressure; craters and high waviness were observed on machined surface. Surface waviness (SW) and craters sphericity were observed at many places of machined pocket through 3-D optical profilometer with objective lens (5x) and field of view (FOV 2x) along with the SPIP software. SW was found high at corners (side wall) of the pockets. Digital microscope of 230x and a scanning electron microscope (SEM) were used to observe and analyze the micro structure of the machined pockets.
