A comparison between conventional and ultrasonic-assisted GFRP Machining

GFRPs (Glass fiber reinforced polymers) are used in a wide range of applications because of their unique properties like high specific strength and stiffness, low density, good durability and corrosion resistance as well as relatively low cost. Milling and grinding are mostly used for machining of GFRP. Ultrasonic assisted machining is one of the hybrid processes often used to increase the productivity. This article is focused on comparing milling and grinding in terms of cutting forces, surface roughness and tool wear for ultrasonic assisted and conventional machining. The work describes both technological (workpiece quality) and economical (processing time) aspects of machining. Additionally, an empirical analysis for milling of GFRP based on the analysis of variances is presented. (C) 2020 The Authors. Published by Elsevier B.V.
