Investigation of Chip Formation and its Grain Structure using Vegetable Oil Based Lubricants

Abstract

This research aims to compare the chips formed by using different vegetable oil based lubricants such as coconut oil, cooking oil, hair oil etc. For this purpose, drilling was affordable and easy process which was used. The process was applied on AISI 1080 Mild Steel and chips and their grain structure were examined through Material Testing Microscope model TESCAN (MIRA 3 XMU Type) to check surface morphology. As a result of chip analysis through Material Testing Microscope; coconut oil gave better chip length with better grain structure. The lubricants or material can be changed to see the difference or resemblance of chip structure formed as a result.
