Experimental investigation on machining of hardstone quartz with modified AJM using hot silicon carbide abrasives

Abstract

This study aims to analyze the accomplishment of cutting performance in hot abrasive jet machining (HAJM) of hardstone quartz concerning surface roughness, taper angle, and material removal rate. Fifteen sets of experimental trials were conducted by considering three cutting parameters (air pressure, abrasive temperature, standoff-distance) based on Box-Behnken's design of experiments. Additionally, response surface methodology, analysis of variance, and statistical technique (here, desirability function approach) followed by computational approach (here, genetic algorithm) are, respectively, employed for experimental investigation, predictive modeling, and multi-response optimization. Thereafter, the effectiveness of proposed two multi-objective optimization techniques is evaluated by confirmation test and subsequently, the best optimal solution is used for cost analysis to rationalize the usefulness of hot abrasives in AJM process with an intension to raise the awareness in the manufacturing industry. Based on results, application of hot abrasives in AJM process has shown an attention in enhancing the cutting performance for material removal.

A Review on the Abrasive Water-Jet Machining of Metal–Carbon Fiber Hybrid Materials

“…The removal of material during abrasive water-jet cutting is based on the continuous impact of solid particles on the material. This process can be divided into four sub-mechanisms in which abrasive particles erode the material surface: cutting, fatigue, melting, and brittle fracture [35,36]. These mechanisms do not act separately, but in combination.…”

Machining performance evaluation under recently developed sustainable HAJM process of zirconia ceramic using hot SiC abrasives: An experimental and simulation approach

“…The complete HAJMing system designed by Pradhan et al 42 in Figure 1, used for machining of brittle materials with a sharp 190 mm diameter of D2 steel nozzle orifice (L to D ratio of 1.47; contraction coefficient of 0.62). This was equipped with a mixing chamber as well as heating arrangement followed by thermal regulator for temperature measurement, a single acting reciprocating compressor (180 liter of atmospheric air storage capacity, 22 kgf/cm 2 of testing pressure, 12 kgf/cm 2 of working pressure, 1 HP of power and 1430 rpm of speed) and a linear stage system which included a pulse damper.…”

“…H et al used CFD tool fluent for predicting the profile of pressure and velocity in AJM 39 at various boundary conditions in the nozzle exit before it impacts on the workpiece surface. K-60 alumina ceramic 40 and quartz 41,42 were used in newly developed FB-HAJM for getting the MRR, DOC and TA by taking SOD, jet pressure, grain size of SiC and abrasive temperature with grey relational analysis (GRA) optimization technique. Hard brittle materials [43][44][45] were used to achieve better surface roughness, kerf taper, groove depth and width by AWJM and AJM using extended finite element method.…”
