Surface roughness study on aluminium in high speed turning process

Surface integrity was the surface condition of a workpiece after being modified by a manufacturing process and it can change the material's properties. In surface topography, surface roughness (Ra) was concerned with the geometry of the outermost layer of the workpiece texture and the interface...

description	Surface integrity was the surface condition of a workpiece after being modified by a manufacturing process and it can change the material's properties. In surface topography, surface roughness (Ra) was concerned with the geometry of the outermost layer of the workpiece texture and the interface exposed with the environment affects several functional attributes of parts, such as friction, wear and tear, light reflection, heat transmission, ability of distributing and holding a lubricant, coating etc. Therefore, the desired surface finish was usually specified and appropriate processes were required to assess and maintain the quality of a component. The objective of the study aims to investigate the influence of machining parameters to the surface roughness value, Ra during high speed turning of aluminium steel material under dry condition. Experimental preparations• were made to ensure the smoothness of the experimental operation. Pilot experimental will be conducted to verify all the machine parameter. All equipment used such as the CNC turning machines, microscope were inspected. CNC programming was also prepared before conducting the machining experiment. Using taguchi as the design of the experiment with three parameters such as cutting speed range within 158.96 m/min to 317.93 m/min, feed rate range of 0.1 mm/rev to 0.3 mm/rev and depth of cut range within 0.5 mm until 1.0 mm. From the experiment conduct, best result is 0.279 μm with parameters of 158.96 m/min, 0.2 mm/rev and depth of cut of 0.75 mm. Optimizations of parameters show that by using cutting speed of 172.509 m/min, feed rate of 0.25 mm/rev with depth of cut 0.99 mm; minimum surface roughness (0.014629 μm) can be achieved.
