Experimental framework and study of AWJM process for an aluminium 6061 alloy using RSM

Last decades have witnessed a rapid growth in the development of harder, difficult and complexity to machine metals and alloys. The use of water and abrasive in such a type of machining i.e., AWJM is one of the most recently developed nontraditional hybrid mechanical type machining in processing different kinds of hard-to-cut materials nowadays. It is an economical method for heat sensitive materials that cannot be machined by processes that produce heat while machining. The principle in which the machining process is done by the mixture of water and abrasives under high pressure jet which provides high velocity that the metals and alloys. Machining parameters play the lead role in determining the machine economics and quality of machining. In this work the consequence of five process parameters on MRR and SR of an American element named Aluminium 6061 alloy which is cut by abrasive water jet cutting machine was experimentally done and analyzed. According to Response Surface Methodology different sets of experiments were conducted on this American element by varying five different parameters. To study the projected second-order polynomial model for MRR and SR, a Box Bekhen based design is assigned to provide the estimated model coefficients of the five input parameters. Experiments were conducted on Aluminium 6061 alloy. By RSM the response is modeled on experimental data. The momentous coefficients are obtained by performing ANOVA at 5% level of significance. It is found that all the input parameters, with their interactions have major outcome on the MRR and SR.
