Abstract
Aim: By comparing two different kinds of tools on the reinforcement composite made of lightweight material like AA7475 + ZrN + fly ash, the This project’s main goal is to produce good surface roughness.
Materials and Methods: Stir casting is used to create the novel, lightweight composite material AA7475 + ZrN + fly ash. The cast composite is prepared as workpieces for CNC machining and pre-processed to remove surface imperfections. Group 1 HSS tool and group 2 coated Tungsten carbide (WC) tool, each group needed the same number of participants, which was determined to be sixteen. The speed, feed, and depth of cut at four levels in sixteen possible combinations for dry machining or green production. When compared to the assistance provided by using surface roughness on machined surfaces, the overall performance of HSS and TiAlN covered WC tools is superior.
Results: Sample surface roughness was statistically examined group by group using SPSS. With a p value of 0.000 (p < 0.05), these findings demonstrated a statistically significant difference between the two groups. demonstrating the statistical independence of the observations and the validity of the statistical assumption that was discovered. The mean surface roughness of samples created with the TiAlN coated WC tool is less than that of samples created with the HSS tool.
Conclusion: Within the restrictions of this study, TiAlN coated WC tool offers lesser surface roughness than HSS tool.
