Influence of pre-heating technique on the titanium alloy for machinability using mill insert

Ti6Al4V is a composite material with low density (4.5 g/cm3), melting point (16680C), and modulus of elasticity (107 GPa). Ti6Al4V’s ambient temperature tensile values can reach 1400 MPa, and its yield strength is noted. The Ti6Al4V alloys are also extremely malleable, making them simple to make and machine. The cutting capabilities of titanium compound will be improved by introducing and registering a novel technique presented in this work. Pre-heating the workpiece with an induction coil heating device before end milling on a vertical machining centre will be studied (VC450-Spinner). WC-Co/PCD inserts placed 25 mm across the mill (R390-025B25-11M/R390-170408E-NLH13A) were thoroughly studied with general preheating method on Ti6Al4V machinability metrics like span of tool, Ra & Fc, noise, anomalies, tool, and morphology. Similarly, bare WC-Co was widely used in warmed machining (straight around multiple times compared to room temperature machining), and estimates of tool life are basically greater than those for cutting with PCD in room temperature machining. Preheated milling reduces shaking and noise, which in turn reduces cutting power and increases the lifespan of the tool. Preheated milling also increased chip-device contact length, lowering tool wear. The device also improved tool life and surface roughness by optimising cutting settings and preheating temperature. Lastly, preheating improved bare WC-Co execution and PCD tool life predictions under room temperature milling. By reducing disturbance and noise and the resulting cutting power, preheated milling promotes longer tool life. Preheated milling increases chip-tool contact length, which reduces tool wear.
