Identification of friction and heat partition model at the tool-chip-workpiece interfaces in dry cutting of an inconel 718 alloy with cbn and coated carbide tools

Abstract: S u m m a r yThis paper aims at characterizing the frictional behaviour at the cutting tool-workmaterial interface during the dry machining of a Inconel 718 in its aged state with various coated carbide tools and c-BN tools. A specially designed open tribometer has been used to characterize friction coefficient, heat partition coefficient under extreme conditions corresponding to the ones occurring in cutting. The tribometer provides the evolution of the apparent friction coefficient and of the heat partition … Show more

“…The friction characteristic at the tool-chip interface is difficult to determine since it is influenced by many factors; such as, the local cutting speed, contact pressure, temperature, cutting tool, work piece material, etc. [51]. An improper selection of the friction coefficient affects the results and findings.…”

“…Dlatego jest szeroko stosowany w przemyśle lotniczym, między innymi na silnie obciążone cieplnie korpusy turbin, komory spalania, zawory wydechowe, łopatki turbin itp. [6,7]. Najbardziej popularnym stopem na bazie niklu jest Inconel 718, z którego wykonywanych jest ok. 45% odkuwek i 15% odlewów [1].…”
