obtain the optimum parameters for cutting hard and tough material (hardox steel) by abrasive water jet cutting process
abstract: nowadays, the non-traditional processes such as “laser, edm and awj” used for cutting high thickness sheet metal. hardox is hard and tough steel alloy and it has many industrialize applications. one best process to cut the hardox is abrasive water jet (awj) cutting. it can cuts complex shape with high quality and accurate tolerance. awj cutting offers certain unique benefits such as...
متن کاملnumerical simulation of abrasive water jet cutting process using the sph and ale methods
on account of some complexities such as fluid-structure interaction and extra-large deformation problems, complete simulation of abrasive water jet cutting process is very hard. the main goal of this paper is to overcome these difficulties through comprehensive simulation in ls-dyna commercial software. for this purpose the smoothed particle hydrodynamics (sph) and arbitrary lagrangian eulerian...
متن کاملForecast Surface Quality of Abrasive Water Jet Cutting Based on Neural Network and Verified by Experiments
In this study, firstly, the YL12 aluminum alloy is used as experimental materials, then in the following experiments it is cut in JJ-I-type water jet machines, and 1,000 group data are gotten by measurement. In each group data, pressure, material thickness, surface roughness, abrasive flow and traversing speed are included. Next, BP artificial neural network is established. In this network, the...
متن کاملTest Parameter Analysis in Abrasive Jet Cutting of Rocklike Materials
This paper contains investigations on the behavior of five artificial rocklike materials subjected to abrasive water jet cutting. The influence of the test parameters, i.e. applied pump pressure, traverse rate and abrasive mass flow rate was investigated, as well as the influence of several material parameters, e.g. compressive strength, Young's modulus, absorbed fracture energy and crack veloc...
متن کاملTurbulent solid–liquid flow through the nozzle of premixed abrasive water jet cutting systems
A computational fluid dynamics analysis has been conducted for the steady state, turbulent, solid–liquid flow through nozzles used in premixed abrasive water jet cutting systems. The development of a theoretical approach to the evaluation of turbulent flow and particle dynamic properties in the nozzles is attractive because of the difficulties associated with direct measurements in nozzles of h...
