Machinability Studies on Commercially Pure Titanium (Grade-2) Under Cryogenic Condition

ABSTRACT

In this investigation, commercially pure titanium (grade2) was machined under cryogenic conditions at high cutting speeds with varying feed rates and depths of cuts. A Taguchi orthogonal array is used to choose the cutting parameters. The output responses include experimentally confirmed cutting forces (V_c), surface roughness (R_a), tool wears, chip production, and chip shape. In order to obtain the final significant machinability, an excellent parametric combination for the work section was obtained by GRA. ANOVA was used to estimate the percentage contributions of the control components. Finally, the cryogenic liquid significantly lowers the cutting temperatures even at high cutting speeds, producing chips with favorable serrations.
