Investigation of Abrasive Wear Performances of Different Polyamides by Response Surface Methodology

Abstract

This study presents the investigation of abrasive wear performances for polyamides using a Response Surface Methodology (RSM). Tests were carried out in a pin-on-disc using various conditions against SiC abrasive cloth. Box-Behnken Design of RSM was adopted to study the effect of control factors like load, speed and tensile strength of the tested samples on the volumetric wear rate. The experimental results indicated that the volumetric wear rate increased with increasing load, speed and decreased with increasing the tensile strength, but material property was more effective than other factors. Furthermore, the results of analysis of variance showed that tensile strength was predominant factor on the abrasive wear rate, followed by load and spindle speed. The contributions of tensile strength, load and speed were about 33.55 %, 24.45 % and 21.87 %, respectively, while the contribution of square and 2-way of interaction was about 3.04 % and 11.23 %, respectively.

Multi-response optimization in cutting mild steels

“…Therefore, optimum cutting parameters should be determined. In this case, a better way is to apply some methodology like Taguchi, factorial, response surface and artificial neural network approach to limit the experiment runs, hence, leading to save times, materials and tools [5][6][7][8] in spite of the fact that there are considerable differences among those methodologies. RSM is the most generally accepted optimization method that is employed in many engineering areas like chemical and manufacturing processes to fit an empirical and measured output.…”

Optimization of Abrasive Wear Parameters of Halloysite Nanotubes Reinforced Silk/Basalt Hybrid Epoxy Composites using Taguchi Approach

“…Hard and rough surface slide through the softer surface resulting in the removal of material in two body abrasion, while three-body abrasion is caused by the slipping and rolling of harder particles entrapped in between the sliding surfaces. Most of the material removal processes in agricultural products and engineering structures occur by three body abrasion [24]. Yousif et al [25] employed betelnut fibre to improve the wear resistivity of unsaturated polyesters.…”
