Vegetable Based Cutting Fluids

Long polar fatty acid chains provide high strength lubricant films.

Vegetable based cutting fluids. Experimental studies on the performances of both new developed environmental friendly vegetable based cutting fluids refined sunflower and canola oils including different percentage of extreme pressure ep additive and two commercial cutting fluids semi synthetic and mineral cutting fluids in turning processes were reported in this work. In this investigation two samples of cutting fluids are prepared using groundnut and cottonseed oil. Temperature of the workpieces as well as their chip formation rates using the vegetable oil as cutting fluids under different cutting speed rev min feed rate mm rev and depth of cut mm were compared with that of mineral dry machining. The vegetable oil based cutting fluids were formulated with various additives to meet the specifications such as resistance to bacterial growth corrosion antifoaming agent and antiwear characteristics.

A wide variety of cutting fluids are commercially available in the cutting fluid suppliers in order to provide machining performances for a number of industries. Table 3 shows the characterization of vegetable based cutting fluids developed for the study. Vegetable oils are the predominant alternatives to the conventional mineral oil based cutting fluids by dispersing the different types of nano particles the physical and thermo chemical properties. Subsequently vegetable oil based cutting fluid such as olive oil was used for next sets of machining.

In machining mineral synthetic and semi synthetic cutting fluids are widely used but recently uses of vegetable based cutting fluids have been increased. Vegetable oils consist of triacylglyceride triglycerides which are glycerol molecules with three long chain fatty acids attached at the hydroxyl groups via ester linkages. Effects of vegetable oil based cutting fluid in turning aisi1040 steel by uncoated carbide tool. In this study a set of turning experiments on new nickel based alloy i e inconel 800 alloy was performed to explore the characteristics of different.

The results on austenitic steel revealed that the cutting force under vegetable oils and esters modes were low compared to reference mineral oils. Vegetable based cutting fluids vbcfs minimum quantity lubrication mql and near dry machining have higher potential of use under these limitations. Cottonseed oil based cutting fluids having two samples one with 90 base fluid and 10 vegetable oil and other with 80 base fluid and 20 oil. Two different groups of cutting fluids such as water based and straight oils including mineral synthetic and vegetable based formulations were tested.

Recently the application of nano cutting fluids has gained much attention in the machining of nickel based super alloys due their good lubricating cooling properties including thermal conductivity viscosity and tribological characteristics.
