Effect of hybrid tri-nano flood cooling environment and shearing parameters on surface quality with tool health in helical milling of Ti6Al4V

Hole milling is strenuous in the Titanium Alloy grade 5. Ti6Al4V has extraordinary metallurgical properties, so it has popularity in the Aerospace, Automobile, and Ship-building industry. The lower heat absorbing ability, springiness, and chemically activeness at higher temperatures, strain hardening consensuses, poor tool life, and damaged surface texture. This is a common issue in Ti6Al4V machining allows penurious machinability. This investigation focuses on the effect of cooling strategies like a typical flood, Minimum Quantity Cooling Lubrication, and novel Hybrid Tri-nano Flood Coolant with popular cutting inserts in Hole milling. A total L9 orthogonal arrays performance quantifying in terms of the Crater, Flank wear, and Average Surface Roughness value (Ra) at a sidewall and bottom of the Hole. Analysis of Variance manifests that the Tool type and Coolant are more significant for wear control and superior surface quality in the Ti6Al4V Hole milling by balanced Lubri-Cooling. Optimum results were acquired by adapting the 65 m/min cutting speed, Axial Depth of Cut is 0.6 mm, and Hybrid Tri-nano Flood Coolant through PVD-TiAlN + TiN coated inserts. However, the Radial Depth of Cut is 45% of the tool diameter, and the Ramp angle should be 1.24 degrees constant through the hole milling. All these shearing parameters in the hole milling of Ti6Al4V under the Helical milling Computer Aided Milling tool path revamp.
