Abstract

The comparison of an analytical and numerical method to calculate the plastic strain, shear angle, and chip tool contact length in hot machining of Inconel 718 using flame heating has been discussed in the present study. The workpiece was heated with the combination of liquid petroleum gas along with oxygen gas. Merchant analytical model has been utilized for calculation of plastic strain, shear angle, while Sutter model is used for chip-tool contact length. DEFORM software has been used to find out the chip-tool contact length (L), shear angle (Φ), shear strain (ε) in the numerical model. It was observed that shear angle and chip tool contact length increased and plastic strain decreased with the increase of cutting speed and feed rate. From the numerical study, a good correlation was found for shear angle, chip tool contact length with the analytical model.
