Abstract
The aim of this work was to analyze the influence of tool geometry on surface roughness and find optimum tool geometry for end milling AL2014-T6. The parameters considered in the present work are the cutting fluid, speed, feed, depth of cut, concavity and axial relief angles in the end cutting edges of the mill. Surface roughness models with both dry-cut and coolant conditions were built by using of Response Surface Methodology (RSM) conducted well. The results show the roughness with dry-cut operation is greater than the roughness with coolant operation. For a better surface finish of AL2014-T6, the concavity angle of 2–3° and axial relief angle of 5–6° are suitable in this investigation.
