In the present study, drilling tests were carried out on Custom 450 stainless steel workpieces. The influences of control factors (cutting speed-Vc, feed rate-f and drill bit geometry-D) drilled holes’ surface roughness (Ra) size adhering workpiece (AW) to was examined. results obtained from designed based Taguchi’s L16 orthogonal array analysed using ANOVA grey relational analyses (GRA). There...

The well-known quality improvement methodology, robust design, is a powerful and cost-effective technique for building quality into the design of products and processes. Although several approaches to robust design have been proposed in the literature, little attention has been given to the development of a flexible robust design model. Specifically, flexibility is needed in order to consider m...

Reducing the number of model parameters without adversely affecting model accuracy narrows the width of confidence intervals for model parameters. That is, for a specific interval width, it raises the level of confidence. This article presents a new method for reducing the number of dynamic model parameters in transfer function modeling. The method involves determining sets of parameters within...

Structural Health Monitoring (SHM) using nondestructive test (NDT) data has become very promising for finite element (FE) model updating, model verification, structural evaluation, and damage assessment. This research presents a multiresponse structural parameter estimation method for the FE model updating using data obtained from a nondestructive test on a laboratory bridge model. Having measu...
