Influence of Cutting Fluid Conditions and Cutting Parameters on Material Removal Rate (MRR) in Taper Turning Process of En31

The present scenario depicts many surveys that represent the machining industries using cutting fluid have more trouble in employee health as well as environmental pollution. The introduction of minimum quantity lubrication has brought disadvantages of wet machining process to been replaced by Minimum Quantity Lubrication (MQL). MQL is increasingly finding its way into the area of metal industries. It has already established as an alternative to conventional dry and wet machining methods. In contrast to Dry and Flood lubrication, Minimum Quantity Lubrication use only a few drops of the fluid approx. 5 ml to 100 ml per hour for the machining. The aim of the research is to determine the Minimal Quantity Lubrication (MQL) technique when used for Taper Turning process in CNC Lathe can produce remarkable advantages in Types of Chips formed during the process and the Microstructure. The work piece material that is used in the experiments is EN-31 steel while the carbide is a cutting tool material. Fluid selection is the most important part of MQL machining process; hence the quality of the fluid depends on it. Therefore a superior type such as vegetable oil or synthetic oil is used for lubrication as well as for cutting fluid for machining. The costs of these fluids are high but it eliminates the commitment of costly fluid’s recycling and disposal service. On our analysis, it was found that MQL produces better surface finish than the wet machining process and has surprisingly shown its significance which reduces the cost of the machining process and is also eco-friendly. Hence leading to safe and uninterrupted machining process.
