  7. Abstract:
  8. One of the most important parts of designing turbine blades is machining (milling) process of blade root. There is some implementing problem in material removal processing by milling. Because of low heat transferring of inconel 738 in machine parts there is huge amount of heat which cause high temperature in machine and burning, which reduces the efficiency of milling.One of the common way to reduce the temperature of machine is using coolant fluids, which increases expenses and makes environmental pollution, so it is not completely efficient as an industrial work. In this paper Whit using MQL and some new lubricant had been observed more efficient condition in milling process. The main goal of this thesis is practically approaching to the optimal method for milling Inconel 738 with minimum usage of lubricants, and for this purpose Taguchi method has been selected which needs two outputs: cutting forces and surface roughness, and four inputs: lubrication conditions, Depth of cut,Cutting speed and Feed rate.According to results of this research depth of cut and feed rate are directly related to cutting forces and surface roughness, and also based on testing four lubricants with different viscosities it has been proved that lubricant with high viscosities reduce machine forces, and with low viscosities decrease surface roughness
