The effect of machining parameters on surface integrity of aluminium material using vertical milling machine / Abdul Azim Mohd Zaidi

The surface integrity is defined as enhanced condition of surfaced cause by machining process. It show that surface finish is heavy influence on the mechanical properties on the part produced. The objective of this research is to study the effect of machining parameters on surface integrity of aluminium. It also to analyse the surface integrity of the milled aluminium. This research aim to identify which parameters that has heavy effect on surface integrity after machining. By using vertical milling machine, we can operate face milling process on the aluminium. The result expected is depth of cut and spindle speed heavily influence the surface integrity of the aluminium. Lower depth of cut of the material cause by milling will gave better surface finish we get from it. Same goes to spindle speed, lower speed lead to better surface integrity. While the depth of cut more influence on the surface finish. As the conclusion, certain parameters of machining process can affect the surface integrity as it can change some of properties of the surface.
