Abstract
The present work is an examination of the effect of wear test parameters, viz., track diameter, load and speed on the wear rate of carbon fibre PLA. The specimens for wear test were designed as per the ASTM-G99 type 1 standard. They were printed by Fused Deposition Modelling (FDM) process by considering one of the best combinations of its parameters viz., layer thickness, in fill pattern and extrusion temperature. The wear testing was conducted on the specimens using pin on disc Tribometer by considering three levels of each of the wear test parameters. Wear tests were designed according to L9 orthogonal array. The results were analysed using Taguchi analysis (DOE) on the MINITAB-19 software and it was found that the track diameter is the most significant parameter with respect to wear of carbon fibre PLA. The results of the interaction plot of S/N ratios of wear show that there is a substantial influence of interactions between track diameter and speed, and speed and load on the wear of carbon fibre PLA. But little effect was observed on the wear of carbon fibre PLA as far as the interaction between track diameter and load is considered.
