STUDY AND ANALYSIS OF MINIMUM QUANTITY LUBRICANT(MQL) USING VARIOUS OILS FOR MACHINING OF MILD STEEL (AISI 1006) IN TURNING OPERATION

Abstract

A wide variety of cutting fluids are commercially available in the market. Although, these cutting fluids
are beneficial in the industries, their uses are being questioned nowadays as regards to health and environmental issues.
To minimize the adverse environmental effects associated with the use of cutting fluids, the hazardous components from
their formulations have to be eliminated or reduced.
Today to diminish the negative effects associated with cutting fluids, researchers have developed new bio based cutting
fluids from various vegetable oils.
In the present study it has been observed that, the manufacturing industries and metal industries using the cutting fluids
has become more problematic in terms of workers health and environmental pollution. To obtain safe, environmental
and economical benefits of machining, the research has been carrying out to reduce the use of cutting fluid during
machining. One of the alternatives to wet machining is Minimum Quantity Lubrication from the point of cost, ecology
and human health issues. From Analysis of Means, it is found MQL and high stainless steel tool shown in better
performance on reduction of temperature and metal removal rate.
Furthermore, MQL provides environment friendliness (maintaining neat, clean and dry working area, avoiding
inconvenience and health hazards due to heat, smoke, fumes, gases, etc. and preventing pollution of the surroundings)
and improves the machinability characteristics.
This thesis report presents the effects of minimum quantity lubrication (MQL) by multi vegetable oils based cutting fluids
on the turning performance of mild steel as compared to completely wet machining in terms of metal removal rate,
temperature, cost, and health.
