Abstract
In this study, micro-size drillability of Hardox 500 was investigated by the electro-discharge machining (EDM) method. For this purpose, holes were drilled by using different machining parameters (discharge current, electrode rotational speed, dielectric spray pressure) and the effect of these parameters on machining performance and hole profile was specified. At the end of the tests, it was detected that discharge current and electrode rotational speed increased material removal rate (MRR), electrode wear rate (EWR) and hole dimensional error (DE) whereas dielectric spray pressure increased the MRR values and decreased the EWR and DE values.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde die Mikrobohrbarkeit eines Hardox 500 mittels Funkenentladungsbearbeitung (Electro-Discharge Machining (EDM)) untersucht. Hierzu wurden Löcher mit verschiedenen Bearbeitungsparametern gebohrt (Entladungsstromstärke, Rotationsgeschwindigkeit der Elektrode, Sprühdruck des Dielektrikums) und deren Effekt auf die Bearbeitungsperformanz und das Lochprofil spezifiziert. Am Ende der Versuche konnte festgestellt werden, dass die Entladungsstromstärke und die Rotationsgeschwindigkeit der Elektrode die Materialabtragsrate, die Elektrodenverschleißrate und den Lochdimensionsfehler erhöhten, wobei Sprühdruck des Dielektrikums ebenfalls die Materialabtragsrate erhöhte und die Elektrodenverschleißrate sowie den Lochdimensionsfehler erniedrigte.
