Evaluation of tool radius and machining parameters on cutting forces and surface roughness for AA 6082 aluminum alloy

OpenAlex İngilizce

In this study, the affects of machining parameters on surface roughness and cutting forces during machining on a conventional lathe of AA 6082 aluminum alloy, which is widely utilized in automotive, manufacturing, and aerospace sectors, were investigated. As experimental parameters: CCMT 09T308-304 and CCMT 09T304-304 cutting tools with two different corner radius, 0.25-0.5 mm depth of cut, 0.1-0.2 mm/rev feed rate and 65, 105 m/min cutting speed were used. ANOVA analysis was applied to determine the affects and significance levels of the variables on the surface roughness and cutting force values measured during the machining experiments. In Taguchi analysis, the optimum values of the variables were found by using S/N ratios in the case of “smaller is better”. According to the ANOVA results, the most important variable affecting the surface roughness was determined as feed rate for both cutting tools. In the ANOVA results of the cutting force, the most significant variable was determined as feed rate in the tool with 0.8 corner radius and chip depth in the tool with 0.4 corner radius. As a result of the experiments, the lowest cutting force and best surface roughness values were obtained with CCMT 09T308-304 coded cutting tools with 0.8 corner radius.
