Abstract

Abstract: Abrasive jet machining (AJM) is a new challenging advanced machining process to machine electrically non-conductive materials effectively where the abrasive particles strike the workpiece with high velocity causing little fractures and separated segments are carried away by flowing air. In this paper, the design and assembly of in- house AJM tabletop setup along with its various indigenous subparts like compressor, mixing chamber, nozzle, machining chamber, etc. have been discussed. After the proper fabrication and testing of each subpart, various types of process parameters and their effects on Material Removal Rate (MRR) were studied when performing the machining on Zirconia workpiece. Two different types of abrasive particles are used during machining and MRR is calculated in varying pressure as well as Stand-off distance (SOD). Moreover it is seen that MRR increases with increase in pressure but it declines while increase in SOD. Afterwards MRR is also found to increase in rise of pressure using two separate abrasive particles in the present work.
