Vegetable Based Cutting Fluids

Long polar fatty acid chains provide high strength lubricant films.

Vegetable based cutting fluids. In this investigation two samples of cutting fluids are prepared using groundnut and cottonseed oil. Subsequently vegetable oil based cutting fluid such as olive oil was used for next sets of machining. 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. Table 3 shows the characterization of vegetable based cutting fluids developed for the study.

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. Two different groups of cutting fluids such as water based and straight oils including mineral synthetic and vegetable based formulations were tested. 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. All the samples of prepared cutting fluids are presented in fig.

Vegetable based cutting fluids vbcfs minimum quantity lubrication mql and near dry machining have higher potential of use under these limitations. 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. 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. 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.

Effects of vegetable oil based cutting fluid in turning aisi1040 steel by uncoated carbide tool. 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. 1 there are four different samples of the prepared cutting fluids mentioned in fig. In mql consumption of the cfs is reduced and the mql has been used extensively in the literature marksberry 2007 fratila 2009 sanchez et al 2010 fratila and caizar 2011.

Vegetable oils consist of triacylglyceride triglycerides which are glycerol molecules with three long chain fatty acids attached at the hydroxyl groups via ester linkages.
