Mkulu khalidwe zosapanga dzimbiri zitsulo amakona anayi chubu
Pali mitundu iwiri ikuluikulu ya njira zoyezera katundu wamakina, imodzi ndi yoyeserera ndipo inayo ndi kuyesa kuuma.Kuyesa kwamakomedwe ndiko kupanga chitoliro chachitsulo chosapanga dzimbiri kukhala chitsanzo, kukoka chitsanzocho kuti chisweke pamakina oyeserera, kenako kuyeza chimodzi kapena zingapo zamakina, nthawi zambiri mphamvu zamakokedwe, mphamvu zokolola, elongation pambuyo pakuthyoka ndikuyezedwa. .Mayeso a Tensile ndiye njira yoyambira yoyesera pamakina azinthu zachitsulo.Pafupifupi zida zonse zachitsulo zimafunikira kuyesedwa kwamphamvu bola ngati zili ndi zofunikira pamakina.Makamaka kwa zida zomwe mawonekedwe ake siwoyenera kuyezetsa kuuma, kuyesa kwamphamvu kwakhala njira yoyesera makina.Chiyeso cha kuuma ndi kukanikiza pang'onopang'ono cholembera cholimba pamwamba pa chitsanzo pansi pazikhalidwe zodziwika, ndiyeno kuyesa kuya kapena kukula kwa indentation kuti mudziwe kuuma kwa zinthuzo.Mayeso a Hardness ndi njira yosavuta, yachangu komanso yosavuta kugwiritsa ntchito poyesa katundu wamakina.Mayeso a kuuma siwowononga, ndipo pali pafupifupi kutembenuka ubale pakati pa zinthu kuuma mtengo ndi kumakoka mphamvu mtengo.Mtengo wa kuuma kwa zinthuzo ukhoza kusinthidwa kukhala mphamvu yamphamvu, yomwe ili ndi tanthauzo lalikulu.Popeza kuyesedwa kwamphamvu kumakhala kovuta kuyesa, ndipo kutembenuka kuchoka ku kuuma kupita ku mphamvu ndikosavuta, anthu ochulukirapo amangoyesa kuuma kwa zinthuzo ndikuyesa mphamvu zake zochepa.Makamaka chifukwa cha kupita patsogolo kosalekeza komanso luso laukadaulo wopanga makina oyesa kuuma, zida zina zomwe sizikanatha kuyesa kuuma kolimba kale, monga machubu osapanga dzimbiri, mbale zachitsulo zosapanga dzimbiri ndi zitsulo zosapanga dzimbiri, tsopano ndizotheka kuyesa mwachindunji kuuma.Choncho, pamene chitoliro chachitsulo chosapanga dzimbiri chikayesedwa kuti chikhale cholimba, izi ziyenera kuchitidwa kuti zitsimikizire kuti zikuyenda bwino.
