The present paper review a lubrication condition metal forming process
like forging, extrusion, deep drawing and rolling. The lubricant film at
tool-workpiece interface must able to sustain inconsistencies of
temperature, pressure and velocity, so that a product with desired surface
finish could be deformed. Meanwhile, vegetable oil has a great potential
to replace the current used of petroleum-based lubricant. However,
limitations of vegetable oil need to overcome first before could find
application at industrial scale.
