A Numerical and Experimental Investigation of Rectangular Abrasive Jets for Drilling Operations INTRODUCTION Abrasive jet machining (AJM), until recently, was used mainly in deburring, cleaning, frosting, and marking on hard surfaces.

Its limited usage was due mainly to the bulky equipment associated with AJM, and also because the variables to control. Rectangular pocket milling is a new area where abrasive water jet machining is being introduced.

The main concern in pocket milling by abrasive water jet has been the high variation in the depth of the pocket.

In this study, a simple technique of milling has been developed consisting of a longitudinal pass and a transverse by: Collimated jet, with a tungsten carbide nozzle of 2mm diameter to form an abrasive water jet.

The abrasives used were 60 mesh garnet particles. The abrasives were delivered using compressed air from a hopper to the mixing chamber and were regulated.

The abrasive water jet pressure is manually controlled using the pressure gauge. Investigation of displacement fields in an abrasive waterjet drilling process: Part 2.

Numerical analysis. Abstract. In this paper, the displacement fields associated with the abrasive waterjet (AWJ) drilling process were simulated using the finite element by: develop an Experimental Investigation of the process that can be used for a better understanding of the process.

Abstract. In the present study, CFRP/Ti6Al4V stacks were machined with abrasive water jet using different process parameters in order evaluate the viability of AWJ industrial application as a substitute of conventional by: the drilled cavity and the back-flow of the abrasive jet are not of much concern.

Trepanning involves enlarging previously cut holes; thus, cavity shape and back-flow are again of less importance. The AWJ drilling process, however, involves creating blind holes, whose depth and internal shape may be difficult to control Size: KB.

abrasive water jet: drilling with abrasive water jet. II. RESULTS AND DISCUSSION By analyzing the experimental data, it has been found that the effects of the tow basic parameters, water pressure, and nozzle traverse speed on the smooth depth of surface cut.

The effect of each of these.For abrasive water jets, water is used as the carrier and a water jet accelerates abrasive microparticles. Since the abrasive microparticle is much heavier than water and although it has sharp edges and corners, the cutting effectivity of materials mainly depends on the grinding effect of the abrasive microparticles on the material.Fabrication of Optimal Abrasive water jet Machining using Finite element approach In this experimental investigation sea sand is developed and compared with the available literature of Numerical Simulation and Experimental work of Guihua et al.
