This research work highlights the effects of acoustic emission (AE) signals emitted during the milling of H13 tool steel as an important parameter in the identification of tool wear. These generated AE signals provide information on the chip formation, wear, fracture and general deformation. Furthermore, it is aimed at implementing an online monitoring(More)
This paper aims at investigating the cutting force at the tip of a single point diamond tool (SPDT). Results from five different experimental trials are presented herein. The modeling procedure adopted is predicated on total differentiation of a multivariate function and adaptation of a continuous non-linear finite series convergent scheme. Initial cutting(More)
Contact lens manufacture requires high deal of accuracy and surface integrity. Amidst numerous optical manufacturing techniques, single-point diamond turning is widely employed in the making of contact lenses due to its capability of producing optical surfaces of complex shapes and nanometric accuracy. This manufacturing technique is however affected by(More)
