Abstract

This paperwork will represent the performance analysis of coolant during milling operation. The analysis is focusing on the surface machining. Generally, there have been a few types of cutting fluid in market and the application of 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 which is suitable for the machining operation especially the milling operation or not. Another 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. The experiment is using a carbon steel AISI 1045 as a workpiece material with dimension of 100 x100 x 50. The workpiece is milled using conventional milling machine using bacteriostatic emulsifiable cutting oil (FUCHS) mixed with pure palm oil as the coolant. The parameters setting such as cutting speed is set differently, 100rpm, 200rpm, 300rpm, and 400rpm. The feed rate is 1mm/rev and depth of cut is 0.5mm remains 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 decrease the quality of surface machining. A few factor is identified that affect to the surface roughness which are cutting speed and machining time.
