The kuyeretsa mfundo akupanga kuyeretsa makamaka chifukwa kumayambiriro akupanga kugwedera mu kuyeretsa madzi, zomwe zimayambitsa "cavitation" mu kuyeretsa madzi. Mphamvu yamakina yamphamvu yopangidwa ndi "cavitation" imachotsa zodetsa zamakina ndi zonyansa zosiyanasiyana zomwe zimayikidwa pa workpiece. Akupanga kuyeretsa osati cavitation kwenikweni, komanso limodzi ndi zovuta kwambiri thupi ndi mankhwala zotsatira.
Otchedwa "cavitation" amatanthauza sparse ndi wandiweyani boma pamene alternating phokoso kuthamanga akupanga mafunde propagates mu madzi. Mu wandiweyani, madziwo amakumana ndi kukakamizidwa kwabwino (pafupifupi pang'onopang'ono mumlengalenga), pomwe ali m'malo ochepa, madziwo amakhala opsinjika kapena kupanikizika koyipa. Nthawi zambiri, madziwa amakhala ndi mpweya wochuluka. M'malo ochepa, kuwira kumakula ndikuyamwa kwambiri mpweya wovunda mumadzimadzi; pamene recompressed, thovu kupitiriza kuchepa. Panthawi imeneyi, kuyenda kwa madzi particles ndi inversely proportional kwa pang'onopang'ono kucheperachepera kuwira utali wozungulira. Choncho, pamene radius ikuyandikira ziro, liwiro la kuyenda kwa anthu ambiri liyenera kuyandikira mopanda malire. Ngati kusuntha kofulumiraku kuima mwadzidzidzi pamene kuwira kutsekedwa, mphamvu ya kinetic yomwe imakhazikika mu voliyumu yaying'ono idzatulutsidwa, pang'onopang'ono imakhala mphamvu ya kutentha, mwinamwake imakhala mphamvu yopondereza. Panthawi imeneyi, funde lozungulira lozungulira limafalikira panja kuchokera pakati pa kuwira kotsekedwa. Pa nthawiyi, kupsyinjika ndi zikwi zambiri zamlengalenga. Ngati akupanga pafupipafupi ndi 20KHz, cavitation iyi idzachitika nthawi 20,000 pamphindikati. Choncho, sikovuta kumvetsa kuti akupanga mafunde ndi amphamvu kuyeretsa luso.
