Abstract

Lubrication in machining process plays a very important role in machining because it increases the productivity and quality of the machining process. Today, most Metalworking Fluids (MWF) are petroleum based ones. Due to its advantages, the consumption of MWF is increasing therefore creating many negative effects on the environment. These effects are related to surface and groundwater, and soil contamination. To address this challenge, various MWF alternatives are being explored by scientists. Vegetable oil is a very attractive alternative to petroleum-based lubricants, because vegetable oils are environmentally friendly, renewable, non-toxic, and easily biodegradable. In complement to the experimental method, simulations using chemical application programs such as Hyperchem 8.0 can also be carried out to provide an estimate of how the interaction between components of lubricating oil, lubricating oil and additives, as well as lubricating oil and additives to their attraction properties to certain surfaces (such as metals). In this study, the effect of the addition of eugenol as a bio-additive on the interaction between molecules of jatropha oil lubricant on the surface of the material will be analysed. The results obtained are simulations using Hyperchem 8.0 can be used to predict the physical properties of the lubricating oil.
