A Novel Detection of surface roughness for AA 6063 using Tungsten Carbide coated tool in comparison with Uncoated tool using surface roughness tester

Abstract

Aim: The objective of this research is to identify the Surface roughness of AA 6063 by drilling in Novel CNC drilling using the Tungsten Carbide coated tool and Uncoated tool. The Mitutoyo tester was used for determining the surface roughness for machined samples. Materials and Methods: The Tungsten Carbide coated and Uncoated tools were used for machining the AA 6063 at a length of 20 mm and a diameter of 25 mm. The G - power calculator of 80% is used for finding the sample quantity. A total of 20 samples were machined for two groups, namely control and intervention groups. The ASTM standard method was used for finding the surface roughness in the SJ410-Mitutoyo Surface roughness tester. Results: According to this research, the obtained Surface roughness mean values for AA 6063 samples using the Tungsten Carbide coated tool was 0.84275 μm and the samples machined using the Uncoated tool was 1.9502 μm. The One-Way Analysis of Variance (ANOVA) in SPSS software was used for statistical calculation and the obtained significance level was p= 0.020 (p <0.050). Conclusion: Within the limitations of this research, the samples drilled using the Tungsten Carbide tool must have lower surface roughness than the Uncoated tool.
