• Are vegetable oils good for machining?
  • Despite poor cost-effectiveness, vegetable oils perform well ahead of synthetic oils (aqueous-based) and mineral oils (oil-based) in machining operations. The thermo-oxidative level is low that disturbs the stability of these natural oils. However, esterification/transesterification methods can be adopted to improve the stability [ 13 ].
  • Can vegetable oils replace mineral-oils in machining applications?
  • Research and industrial establishments have forecasted the replacement of mineral-oils (petroleum-based) by vegetable oils in upcoming years. Thus opportunities and challenges are prevailing simultaneously with respect to vegetable oils in machining applications. 11. Conclusion
  • What is a vegetable oil based cutting fluid?
  • Vegetable oils are categorized under the “oil-based” (neat oil) group in the classification of MCFs. Mineral and animal oils are the other two categories that come under neat oils as displayed in Fig. 6. Since oils are derived from animals, minerals, and vegetables, one category falls under “oil-based” cutting fluids.
  • Can vegetable oils replace synthetic cutting fluids?
  • The appropriateness of several vegetable oils is reviewed and compared for various metal cutting applications. This review of research article indicates that vegetable oils are capable of replacing synthetic cutting fluids and this alternative could help in effective and economical means towards achieving green machining. 1.
