Parametric analysis of Abrasives water jet machining of EN8 Material
Abrasive water jet machine (AWJM) is a mechanical base non-conventional machining process. This is process of removal of materials by impact erosion of high pressure (1500-4000 bar), high velocity of water and entrained high velocity of grit abrasives on a work piece. Experimental investigations were conducted to assess the influence of abrasive water jet machining (AWJM) process parameters on ...
متن کاملMultiresponse Analysis in Abrasive Waterjet Machining Process on AA 6351
This study investigates optimal parameter setting in abrasive waterjet machining (AWJM) on aluminium alloy AA 6351, using taguchi based Grey Relational Analysis (GRA) is been reported. The water pressure, traverse speed and stand-off-distance were chosen as the process parameters in this study. An L 9 orthogonal matrix array is used for the experimental plan. The performance characteristics whi...
متن کاملEstimation of the minimum machining performance in the abrasive waterjet machining using integrated ANN-SA
In this study, Artificial Neural Network (ANN) and Simulated Annealing (SA) techniques were integrated labeled as integrated ANN-SA to estimate optimal process parameters in abrasive waterjet (AWJ) machining operation. The considered process parameters include traverse speed, waterjet pressure, standoff distance, abrasive grit size and abrasive flow rate. The quality of the cutting of machined-...
متن کاملA process prediction model based on Cuckoo algorithm for abrasive waterjet machining
Cuckoo is a new evolutionary algorithm which is inspired by lifestyle of bird family. This study proposes Cuckoo algorithm for prediction of the surface roughness of Abrasive Water Jet (AWJ). Several prediction models with different initial eggs were developed and analyzed to investigate the best predicted surface roughness value. The paired sample t-test was used to demonstrate the validity of...
متن کاملMechanics guided design of hybrid laser/waterjet system for machining of hard and brittle materials
The two main objectives of this work is 1) to develop a mathematical model to efficiently capture the fracture behavior of materials undergoing thermal shock and 2) to design and develop a mechanics based hybrid laser/waterjet manufacturing process that will be able to machine hard and brittle materials at higher speeds and with better cut quality. The mathematical model relates the temperature...
