Dissertation note: Project paper (Bachelor of Mechanical Engineering with Manufacturing Engineering) -- Universiti Malaysia Pahang - 2009 Abstract: Surface integrity generally can be described by its topological, mechanical, and metallurgical. Since the defects produced from different machining can affect the performance of component, experiments always will be conducted to understand the effect of changing operating parameters before new machining strategies are accepted. In this study, surface integrity was characterized by surface roughness and microhardness of titanium alloy Ti-6Al-4V. The objectives of the project are investigating milling parameters effect on surface roughness of titanium alloy and the effect of cutting speed to surface hardness of titanium alloy. Three cutting parameters selected to study their effects on surface integrity which are cutting speed, feed rate, and depth of cut. For surface roughness, five levels of each parameter chosen to see their effects when only one factor will be manipulated while the other are kept constant. The sensitivity of surface roughness value to process parameters shows that the feed has the most influence, followed by radial of depth of cut, while cutting speed has the least influence. For microhardness testing, the only factor manipulated is the cutting speed which three levels selected to observe the microhardness values. The result for microhardness is the higher cutting speed, the lower the surface hardness.

Surface integrity generally can be described by its topological, mechanical, and metallurgical. Since the defects produced from different machining can affect the performance of component, experiments always will be conducted to understand the effect of changing operating parameters before new machining strategies are accepted. In this study, surface integrity was characterized by surface roughness and microhardness of titanium alloy Ti-6Al-4V. The objectives of the project are investigating milling parameters effect on surface roughness of titanium alloy and the effect of cutting speed to surface hardness of titanium alloy. Three cutting parameters selected to study their effects on surface integrity which are cutting speed, feed rate, and depth of cut. For surface roughness, five levels of each parameter chosen to see their effects when only one factor will be manipulated while the other are kept constant. The sensitivity of surface roughness value to process parameters shows that the feed has the most influence, followed by radial of depth of cut, while cutting speed has the least influence. For microhardness testing, the only factor manipulated is the cutting speed which three levels selected to observe the microhardness values. The result for microhardness is the higher cutting speed, the lower the surface hardness.
