Investigation on Abrasive Waterjet Machining of Kevlar Reinforced Phenolic Composite Using Taguchi Approach

چکیده
Experimental investigations were conducted to assess the influence of Abrasive Water Jet Machining (AWJM) process parameters on surface roughness (Ra) and kerf taper ratio (TR) of aramid fibre reinforced plastics (AFRP) composite. The approach was based on Taguchi’s Method and Analysis of Variance (ANOVA) to optimize the AWJM process parameters for effective machining. It was found that traverse rate was considered to be the most significant factor followed by hydraulic pressure in influencing the Ra quality criteria. In case of TR, traverse rate showed the greatest influence by standoff distance. The recommended optimal parametric combination for improved Ra and TR performance are A3B2C3D1 and A3B3C3D1 respectively. It was also confirmed that increasing the kinetic energy of water jet may produce a better quality of cuts. It was confirmed that determined optimal combination of AWJM parameters satisfy the real need for machining of AFRP composites in practice.
