Chitsulo chosungunuka chimatsanuliridwa mubokosi la mchenga pansi pa kupanikizika koipa, kotero kuti chitsanzo cha polima chimatenthedwa ndi kusungunuka, ndiyeno chimachotsedwa. Njira yatsopano yoponyera yomwe imagwiritsa ntchito zitsulo zamadzimadzi m'malo mwa nthawi imodzi yopangira nkhungu yomwe idapangidwa pambuyo pozizira komanso kulimba kuti ipange zoponya. Kuponyera thovu kotayika kuli ndi makhalidwe awa: 1. Kuponyera ndi khalidwe labwino komanso lotsika mtengo; 2. Zida sizili zochepa komanso zoyenera kukula kwake; 3. Kulondola kwambiri, kusalala pamwamba, kuyeretsa pang'ono, ndi makina ochepa; 4. Zowonongeka zamkati zimachepetsedwa kwambiri ndipo mawonekedwe a kuponyera amakhala bwino. Zokhuthala; 5. Ikhoza kuzindikira kupanga kwakukulu komanso kochuluka; 6. Ndikoyenera kupanga misala yoponyera ma castings omwewo; 7. Ndi oyenera ntchito Buku ndi yodzichitira msonkhano mzere kupanga ndi ulamuliro ntchito; 8. Mkhalidwe wopangira mzere wopanga umakwaniritsa zofunikira zachitetezo cha chilengedwe. ; 9. Ikhoza kusintha kwambiri malo ogwirira ntchito ndi kupanga mapangidwe a mzere wopangira, kuchepetsa mphamvu ya ntchito, ndi kuchepetsa kugwiritsa ntchito mphamvu.

Mapangidwewa ndi osinthika ndipo amapereka ufulu wokwanira wopangira mapangidwe apangidwe. Zojambula zovuta kwambiri zimatha kuponyedwa kuchokera kumagulu osakanikirana a thovu.
Chepetsani ndalama zogulira ndi kupanga, chepetsani kuchuluka kwa zinthu zomwe simunatchulepo, ndikukhala ndi ndalama zochepa zopangira makina. (1) Kuchuluka kwa magulu oponya (2) Zida zoponyera (3) Kuyikira (4) Mapangidwe oponya
Palibe pachimake pamchenga pamapangidwe amchenga, kotero sipadzakhala makulidwe a khoma osagwirizana chifukwa cha kukula kwapakati pa mchenga kapena malo olakwika pakuponya mchenga.
.Castings ali olondola kwambiri. Kutaya thovu ndi njira yatsopano yopanda malire komanso yolondola. Mchitidwewu sikutanthauza kutenga nkhungu, palibe kugawanika pamwamba, ndipo palibe pachimake mchenga, kotero castings alibe kung'anima, burrs, ndi ngodya kulemba, ndi Dimensional zolakwa chifukwa pachimake kuphatikiza yafupika. Kuuma kwapamwamba kwa castings kumatha kufika Ra3.2 mpaka 12.5μm; kulondola kwapang'onopang'ono kwa ma castings kumatha kufika ku CT7 mpaka 9; machining allowance ndi 1.5 mpaka 2mm kwambiri, zomwe zingachepetse kwambiri mtengo wa makina. Poyerekeza ndi njira yopangira mchenga, imatha kuchepetsedwa ndi 40% mpaka 50% ya nthawi yopanga makina.
Kupanga koyera, popanda zomangira zamadzi mumchenga wowumba, mapulasitiki a thovu ndi ochezeka ndi chilengedwe pa kutentha kochepa, ndipo kuchuluka kwa mchenga wakale kumapitilira 95%.
