Abstract

Abstract: This work presents the preliminary investigation on the orthogonal machining of Zr-based bulk metallic glass. Influence of machining parameters on the chip formation mechanisms has been analyzed. The SEM images of the chip surfaces have been taken for this purpose. It has been observed that at lower speed and uncut chip thickness, the individual serrated sections of chips develop shear bands in the surface. At higher speed and uncut chip thickness, these shear bands aggravate and leads to form fragmented surfaces. Degree of segmentation and serration spacing of chips were analyzed and compared with the morphology of the machined surface.
