Study Into The Effect Of Crude Palm Oil (CPO) As A Cutting Fluid On Surface Finish During Milling.

Lubricants are being utilized in all sectors of industry for lubricating their machines and materials. Reports indicate that nearly 38 million metric tons of lubricants were used globally in 2005, with a projected increase of 1.2% over the next decade. Approximately 85% of lubricants being used around the world are petroleum-based oils. Enormous use of petroleum based oils, created many negative effects on environment. The major negative effect is particularly linked to their inappropriate use, which results in surface water and groundwater contamination, air pollution, soil contamination, and consequently, agricultural product and food contamination.
