Abstract

This project represents the performance analysis of coolant during turning operation. The analysis is made on the surface finish after machining. Generally, a few types of cutting fluid in market and being used as cutting fluid to the machining process will give a few advantages such as producing a good surface finish. The main purpose of this project is to investigate the performance of palm oil application as compound in coolant whether suitable or not for machining operation especially the turning operation. Other purpose is to compare and identify the best coolant between the oil-based coolant and the combination of oil-based coolant with palm oil in the aspect of surface machining. Experiment is conducted using a carbon steel AISI 1045 as a workpiece material with dimension of.250mm x 50mm. The workpiece is being turned by conventional lathe machine using (FUCHS) bacteriostatic emulsifiable cutting oil mixed with pure palm oil as coolant. The parameters setting such as cutting speed is set differently, 185rpm, 340rpm, 425rpm, and 625rpm. The feed rate is 0.5mm/rev and depth of cut is 0.5mm will remain constant. Surface roughness value is taken through the surface roughness tester and surface texture observation is done using metallurgy microscope. As the result, the palm oil compound will affect the surface machining and decreasing the quality of surface machining. A few factor is identified which will affect the surface roughness which are cutting speed and machining time.
