Researchers and practitioners frequently spend more time fine-tuning algorithms than designing and implementing them. This is particularly true when developing heuristics and metaheuristics, where the “right” choice of values for search parameters has a considerable effect on the performance of the procedure. When testing metaheuristics, performance typically is measured considering both the qu...

Recently 304 stainless steel finds many applications like Automotive, Aerospace, Nuclear, Chemical and Cryogenics. The cylindrical grinding parameters on 304 stainless steel are conducted using Taguchi design of experiments of L9 orthogonal array was selected with 3 levels with 3 factors and output parameter of Surface Roughness is measured. The quality of the surface describes the relationship...

This paper presents simulation of High Speed Machining of steel with coated carbide tools. More specifically, Third Wave Systems AdvantEdge commercial Finite Element Method code is employed in order to present turning models, under various machining conditions. As a novelty, the proposed models for High Speed Machining of steel are three-dimensional and are able to provide predictions on cuttin...

This paper discusses the concept and parameter design of a Robust Stair Climbing Compliant Modular Robot, capable of tackling stairs with overhangs. Modifying the geometry of the periphery of the wheels of our robot helps in tackling overhangs. Along with establishing a concept design, robust design parameters are set to minimize performance variation. The Grey-based Taguchi Method is adopted f...

The challenge of current manufacturing industries is increase production rate in order to maintain their competitiveness in market.This paper investigates the effect of spindle speed and feed on material removal rate in turning operation execute on conventional lathe machine. An effort has been made to model the one response variable using Taguchi and ANOVA method. Taguchi L9 orthogonal array i...

To satisfy the volatile nature of today s markets, businesses require a significant reduction in product development lead times. Consequently, the ability to develop precise product sales forecasts is of fundamental importance to decision-makers. Over the years, many forecasting techniques of varying capabilities have been introduced. The precise extent of their influences, and the interactions...

Original scientific paper The present work aims at obtaining parametric combination to achieve the best surface finish and assess effects of selected process parameters on a laser cut quality for laser cutting. This helps to study the variation in response parameter (Ra value) for various levels of selected process parameters. In the present work mild steel specimen is used and the effect of th...

The effects of cutting tool coating material and cutting speed on cutting forces and surface roughness were investigated by Taguchi experimental design. Main cutting force, Fz is considered as a criterion. The effects of machining parameters were investigated using Taguchi L18 orthogonal array. Optimal cutting conditions were determined using the signal-to-noise (S/N) ratio which is calculated ...

The aim of this article is to explore the use of statistical design in biomedical engineering applications. These techniques are not extensively used in this discipline possibly due to the current content of most curriculum. They may however be very valuable in optimizing the performance of biomedical devices and systems. We first review the two major methods of statistical design, namely the T...

The FEM analysis of ultrasonic tool has been done in addition to surface roughness of machined samples using ultrasonic machining process have been presented. The experimental conditions were designed by using DOE approach. The analysis of results has been done using the MINITAB 14.0 software and results obtained are validated by conducting the confirmation experiments. The F-test and P-value h...
