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.
