Abstract
The CNC turning process is a part of material removal processing where the purpose is changing the dimension by reducing the diameter of a cylindrical workpiece. The parameters used for CNC turning in this experiment are feed rate (mm/rev), spindle speed (rpm), depth of cut (mm) and cutting condition which then resulted on the surface roughness for the workpiece either being a high-quality surface or vice versa. There are several conditions that can be used in CNC turning which are dry cutting condition, liquid cooling condition or by using a vortex cooling tube. It is a device that can release a hot and cold air at each end whereby the cold end can be used as a coolant for the turning process. Besides, the liquid coolant also used in the experiment to study the comparison. The variation of parameters used in CNC turning determine the quality of the surface roughness (Ra) and the tool wear (flank wear). The surface roughness is tested by a profilometer. The method used in analyzing the result is 2-k factorial design of experiment (DOE). This DOE explore four factors, with each factor having the minimal two levels. The investigation infers that the vortex tube cooling system shows a positive impact on the result of surface roughness and flank wear. It was identified that the surface roughness was influenced by the feed rate, followed by type of coolant and spindle speed. It was also identified that there was no significant factor influencing the flank wear.
