Utilizing a surface roughness tester, a novel improvement in surface roughness for the AA6020 was made utilizing tungsten carbide-coated tools.

Abstract

Aim: The main goal of this study is to identify the Surface Roughness using roughness tester, analyze how Tungsten Carbide Coated Drill Bit improves Surface Roughness for Novel AA6020, and compare the results to Uncoated Carbide Drill Bit. Materials and Methods: This investigation entails the AA6020 are two groups: The Experiential Groups (AA6020 samples drilled with Tungsten carbide coated drill bit) and the Control Groups (AA 6020 samples drilled with Uncoated Carbide Drill bit). According to g power calculations, the sample size is calculated to be 20 each group, for a total, with a length of 20mm and a diameter of 25mm, is employed in this study. In this study, there sample size of 40. The ASTM Standard is followed when performing the Surface Roughness Tester. Results: The average Surface Roughness, for Experimental Group (Novel AA6020 Drilled with Tungsten carbide coated Drill Bit)  while the Control Group (Novel AA6020 Drilled with Uncoated Carbide drill bit) According to the Surface Roughness Data.When the findings of both groups are compared using the ANOVA test, it is clear the experiential group has a much lower Surface Roughness with significance level of 0.00 (P<0.05). Conclusion: Within the limitations of this study, we may conclude that AA6020 drilled with Tungsten carbide coated Drill Bit produces superior Surface Roughness than AA6020 Drilled with Uncoated Carbide Drill Bit.
