Abrasive waterjet is a novel machining process capable of processing wide range of hard-to-machine materials. This research addresses modeling and optimization of the process parameters for this machining technique. To model the process a set of experimental data has been used to evaluate the effects of various parameter settings in cutting 6063-T6 aluminum alloy. The process variables consider...

The paper solves the problem of the nonexistence of a new method for calculation of dynamics of stress-deformation states of deformation tool-material systems including the construction of stress-strain diagrams. The presented solution focuses on explaining the mechanical behavior of materials after cutting by abrasive waterjet technology (AWJ), especially from the point of view of generated su...

Artificial neural networks (ANNs) have been successfully applied for solving a wide variety of problems. However, determining of ANN architectural and training parameter values still remains a difficult task. This paper is concerned with the usage of design of experiment (DOE) method in order to determine parameter settings of multilayer feedforward (MLFF) ANN trained with backpropagation (BP) ...

This paper describes part of the construction of a second theater in the underground museum complex, below the Gateway Arch in St Louis. Given the needs for relatively quiet, non-intrusive rock removal, and yet precise cutting within the museum complex a method of using low pressure (35 MPa) abrasive laden waterjets was developed for cutting the vertical walls of the theater down to a depth of ...

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...

The high cost of ceramic components can be associated with complex and time-consuming postmachining, which is currently done by using abrasive machining processes. The IWF and Fraunhofer-IPK are undertaking research activities in the field of abrasive machining which aim at developing and optimizing technologies to expand the application field and to increase productivity of high-performance ma...

It is shown that when modeling a single interaction of an abrasive particle with the surface part in process collision under air (liquid) pressure, it necessary to take into account specifics impact-abrasive wear, separation wear preceded by metal destruction. In schematization contact during blasting, some commonality shot blasting and number assumptions typical for grinding, micro cutting gra...
