Abstract

The experiment focused on investigating optimal machining conditions for Hybrid Fibre Reinforced Plastics (HFRP) used in aerospace applications. It aimed to achieve two main objectives which determining the most suitable spindle speed and feed per tooth settings to minimize damage during edge trimming and analyzing tool wear in router-type tools and surface quality for trimming HFRP materials. The study utilized the Design of Experiment (DoE) technique and Taguchi L9 orthogonal arrays to conduct edge trimming on HFRP using a three-axis CNC router model, Roland MDX540. Three different levels of spindle speed (10024 RPM, 7518 RPM, and 5012 RPM) and feed per tooth (0.15mm, 0.1mm, and 0.05mm) were applied. Surface roughness measurements were taken using the Shodensha GR4300, while temperature monitoring utilized a Fluke Ti400 thermal camera. Inspection of tool wear and surface quality was conducted using the Nikon MM-800 measuring microscope. The data collected underwent analysis using the ANOVA method. Ultimately, this study aimed to determine the optimal cutting conditions for HFRP, specifically for trimming aero-structural components, with the primary objective of minimizing damage during the machining process
