The machinability of inconel 718
TL;DR: In this paper, the effect of cutting conditions on the machinability of Inconel 718 was discussed and two types of coated cemented carbide inserts, grades EH20Z-UP and AC25, were tested at a constant depth of cut.
Journal ArticleDOI
Design and manufacture of long-life PM bearings
S.C. Lim,W.K.H. Seah +1 more
TL;DR: In this article, the authors describe the design and manufacture of double-layer self-lubricating powder metallurgy (PM) bearing with a denser core for strength and a more porous case for improved lubricant-retention capability.
Journal ArticleDOI
Approximation of exponential curves for CNC machining of toolholders used in ultrasonic machining
TL;DR: In this paper, the authors presented an approach to approximate the exponential curve required for CNC machining of the exponential toolholder for a given tolerance FEM analysis has also been used to determine the minimum tolerance required to achieve the best resonance for the given amplification ratio and exponential profile.
