1.2 Problems Statements
The problems that be based on this study are:
i. There are limited studies or information that exists regarding to the issue of
the palm oil as the cutting fluid in milling operation. ii.
The current coolants are harmful to the operator compared to the new formula coolant based on vegetable oil organic like palm oil which is environmental
friendly. iii.
There have no study proving that whether palm oil is a suitable solution to mix with coolant. What happened if both of them are mixed?
1.3 Objectives of Project
In recognition the importance of coolant in machining, this project is tried to achieve the following objectives:
i. To study the performance between pure oil based coolant and combination of
oil based coolant with palm oil on cutting surface in milling operation. ii.
To analyze the surface roughness and observe the surface texture of the surface machining that was produced on the workpiece from the usage of the
oil-based coolant mix with palm oil and relating them with the parameters involves.
iii. 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.

1.4 Scope of Project
This project is done to analyse the coolant application in milling operation in Manufacturing Laboratory of UTeM. The coolant to be used in this project is a
bacteriostatic emulsifiable cutting oil. The bacteriostatic emulsifiable cutting oil has mixed with pure palm oil. This coolant afterwards is applied in face milling
operation. All machining processes performed on carbon steel AISI 1045 with several parameters which are time of machining and cutting speed. This study will be
focusing on the surface of machining consist of the surface roughness and surface texture. All of the samples will be analyzed using surface roughness tester and
metallurgy microscope. The discussion will be done based on the result obtained.
