Studies on Tribological and Metal Forming Performance of Vegetable Oil-Based Lubricants
Oils derived from vegetable source are being investigated to serve as a possible alternative to conventional oils, currently being used as base oil in metal forming and metalworking processes. In the present investigation, friction and wear studies on AISI 304L with chemically modified neem and mahua oil-based lubricants are made with the aid of pin-on-disc tribometer. Feasibility of chemically modified neem and mahua oils as lubricant for drawing AISI 304L is also investigated. Neem and mahua oils are chemically modified by esterification and epoxidation process. Raw and chemically modified oils are compared with mineral oil-based lubricants. Chemically modified version of oil showed better resistance in the prevention of material wear and friction under frictional slide over base plate of the pin on the disc. The thickness profile, punch load and draw-in-length are observed for the deep-drawn cups under raw and formulated vegetable oils and are compared with mineral oil. The results obtained indicate that vegetable oils are good alternative to mineral oils for metal forming applications.
