Choyamba ndi kupanga mapangidwe amipangidwe yamkuwa.
Popanga, kuwonjezera pa kudziwa geometry ndi kukula kwa gawo potengera zikhalidwe ntchito ndi zitsulo katundu katundu, rationality kamangidwe ayeneranso kuganiziridwa ndi maganizo a kuponya aloyi ndi kuponya ndondomeko makhalidwe, ndiko kuti, zoonekeratu kukula zotsatira. ndi kulimbitsa ndi kuchepa. , kupsinjika maganizo ndi zinthu zina kuti mupewe kapena kuchepetsa zochitika za zolakwika monga kugawanitsa kwamagulu, kusinthika, ndi kusweka kwazitsulo zamkuwa.
Zojambula zamkuwa
Chachiwiri, payenera kukhala ukadaulo wokwanira woponya.
Ndiko kuti, malinga ndi dongosolo, kulemera ndi kukula kwa castings mkuwa, kuponya makhalidwe aloyi ndi zinthu kupanga, kusankha yoyenera malekezero pamwamba ndi mawonekedwe, pachimake kupanga njira, ndi zomveka anaika mipiringidzo kuponyera, chitsulo ozizira, risers ndi machitidwe gating. Kuonetsetsa kuti castings apamwamba.
Chachitatu ndi khalidwe la zipangizo ntchito poponya.
Ubwino wa zida zachitsulo, zida zopangira mafuta, mafuta, ma fluxes, zosintha, mchenga wotayira, zomangira mchenga, zokutira ndi zinthu zina ndizotsika, zomwe zingayambitse zolakwika monga pores, pinholes, ma slag inclusions, ndi kumamatira mchenga m'magawo, zomwe zimakhudza mawonekedwe a copper castings. Ubwino ndi mtundu wamkati, muzovuta kwambiri, ma castings amachotsedwa.
Chachinayi ndi ntchito ya ndondomeko.
Ndikofunikira kupanga njira zoyenera zogwirira ntchito, kukonza luso la ogwira ntchito, ndikuwonetsetsa kuti njirazo zikutsatiridwa bwino.
