Cutting edge preparation is proven to improve the tool life by avoiding sudden failures. Honed edge is effective in stabilizing the tool but has an adverse effect on surface quality. Tailored edge draws attention for research in improving the tool life and surface quality compared to symmetric honed edge. This research describes the advantages and limitations of trumpet edges over symmetrically honed edges in tool life and surface quality. The analysis carried out in milling of AISI 4140 steel with the trumpet edge of K=1.6 produced a surface of stable Ra value around 0.2μm with good quality. The tool life was not significantly varied with the trumpet edges since the both trumpet edge and symmetrical edges resulted in a tool life around 95 minutes. The results predict a distortion of tailored edge as it machines the work piece since the K-factor was reduced from 1.6 to 0.9.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
