Waterjet cutting is a non-conventional cutting technology. Important criteria of the cut surface are geometric accuracy and surface roughness. The aim of this paper is to provide predictive models to estimate average surface roughness (Ra), taking into account significant effects. Full factorial design of experiments were used in the waterjet cutting tests. The input parameters were plate thick...

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 ...

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) ...

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...
