Using Nano-Fluids Minimum Quantity Lubrication (NF-MQL) to Improve Tool Wear Characteristics for Efficient Machining of CFRP/Ti6Al4V Aeronautical Structural Composite

The aeronautical industry constantly strives for efficient technologies to facilitate hole-making in CFRP/Ti6Al4V structural components. prime challenge this direction is excessive tool wear because of the different engineering properties both materials. Nanofluid minimum quantity lubrication (NF-MQL) latest technology provide synergistic improvement tribological and function during machining. In current study, an MoS2-based NF-MQL system was applied helical milling using a FIREX-coated tool. In-depth analysis wear, scanning electron microscope (SEM), deposition spectroscopy (EDS) were used evaluate workpiece elemental transfer mechanisms. Experimental findings showed that 1% nanoparticles concentration lubricant resulted low 13 µm after 10 holes. SEM EDS analyses depicted formation tribo-film on surface, resulting less severe reduced degree adhesion. However, nanoparticle 0.5% 106 holes with slight evidence tribo-film. Parametric based eccentricity, spindle speeds (individual CFRP Ti6Al4V), axial pitch, tangential feed correlations mechanical damage. An extended study up 200 diffusion C element at high rate as compared metal elements such W Co. lowest observed eccentricity level 1, speed Ti6Al4V 1000 rpm, 7500 0.01 mm/tooth, pitch 1.5 mm, MoS2 nanoparticles.
