Abstract

Abstract

AthermaltransfermodelforAl2O3ceramicsduringmicro-detonationofstrikingarcmachining( MDSAM)wasestablished.Basedonthefiniteelementtheory,thetemperaturefieldofAl2O3 ceramicsduringMDSAM wassimulatedwiththeaidoftheANSYSsoftware.Combinedwiththematerialproperties, thesimulatedcavitydimensionwascomparedwiththemachiningexperimentalresultandtheeffectsofthemachiningparametersonthetemperaturef eldwereanalyzed.ThesimulatedresultsshowthatthehighesttemperatureofAl2O3ceramicsduringMDSAMcanreach13435℃ withthegivenmachiningparameters.Theheat-affectedzoneisquitesmallandthemachiningtestis consistentwiththesimulatedresults.Withtheincreaseofthepulsewidthandtheworkingcurrent, thetemperatureoftheprocessingregionandtheradiusanddepthofthecavityincrease.Thetemperaturedecreaseswiththeincreaseofthenozzleradius, whereasthediameter-to-depthratioofthecavity increases.Thesimulatedresultscanprovideanimportantreferenceforthepredictionofthesurface topography,thedisclosureofthematerialremovalmechanism,andtheoptimizationofthemachining parametersforAl2O3ceramicsduringMDSAM.
