Hoher Werkzeugverschleiß bei der Bearbeitung schwer zerspanbarer Werkstoffe führt zu geringen Standzeiten und inhomogenen Randschichten der Bauteile. Manuelle Verschleißuntersuchungen erfordern eine Unterbrechung der Fertigungsprozesse, was die Produktivität senkt. Durch Körperschallsensoren werden die akustischen Emissionen beim Außenlängsdrehen von Ti-6Al-4V erfasst und geeignete Merkmale identifiziert, welche eine indirekte Verschleißschätzung während des Prozesses ermöglichen.
High tool wear during machining of difficult-to-cut materials leads to low tool life and inhomogeneous surface layer properties of the components. Manual wear examinations require an interruption of the manufacturing processes, which reduces productivity. By means of structure-borne sound sensors, the acoustic emissions during the external longitudinal turning of Ti-6Al-4V are recorded and suitable features are identified, which enable an indirect wear estimation during the process.
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.
