Parametric effect of minimum quantity lubrication unit using RSM technique to improve the machinability of Inconel 718

In recent years, a rapid demand of superalloys has been seen in all industrial sectors. Few growing indus-tries such as aerospace and biomedical industries are in need of this superalloy for fabrication of variety of products. Inconel 718 is one such superalloy which is being used for the manufacture of these produc-tions due to high tensile strength, corrosion resistance, hardness and toughness. Due to these superior quality feature of this material friction is being seen at the tool-work interface region. This friction can be reduced by minimum quantity lubrication (MQL) unit which provides coolant at the right time. This paper discusses the minimum quantity lubrication unit used in computer numerical control (CNC) milling machine to improve the machinability of Inconel 718 by reduction of temperature at tool-work interface region and also the parametric effect using response surface methodology (RSM). Minimum quantity lubrication unit allows the cutting fluid to flow out of the nozzle at minimum speed to the cut-ting region which provides maximum volume of heat removal at very minimized usage of fluid. RSM technique is being implemented to improvise the experimental runs with proper way of extracting the readings and providing the observations. Instead of generating huge datas, RSM shows the accurate path of providing the data in a specified generative table.
