Kuyang'anira musanayambe chithandizo cha kutentha kwa yankho ndi njira yowunikiratu kuti muwone momwe zinthu zamalizidwira komanso kukula kwake molingana ndi luso, kufa.kupangakujambula ndi ndondomeko khadi pambuyo forging kupanga ndondomeko yatha. Kuyang'ana mwachindunji kuyenera kuyang'ana mbali izi:
(1) maonekedwe ayenera kukhala opanda ming'alu, palibe chosema mphete kutentha mankhwala khalidwe adiresi dzimbiri, okusayidi khungu ndi mikwingwirima ndi zolakwika zina.
(2)Zojambula zonse zakufa zokopaziyenera kusonyeza miyeso ikuluikulu, magawo apadera a mawonekedwe, magawo a mtanda, mawonekedwe ndi malo a mabowo.

(3) Kukula ndi kulondola kwakufa zokopakukhala mbali kutentha mankhwala ayenera kusonyeza Machining allowance, pamwamba roughness, dimensional kulondola, malo kulondola ndi mawonekedwe olondola.
(4) oyendera malinga ndi chiwerengero chakufa zokopamtanda 10% -20% malo cheke pansi-anzanu, pamene mtanda wa malo cheke forgings mogwirizana ndi kujambula, akhoza kulowa ndondomeko kuyendera. Zolemba zomwe zimafufuzidwa kuti ziyeneretsedwe asanazimitsidwe ziyenera kusungidwa padera.
(5) Musanazimitse, yang'anani shelufu ya zinthu zomalizidwa, 1-2zojambulaziyenera kuyikidwa sampuli (kupinda ndi kusweka zinyalala sizingagwiritsidwe ntchito sampuli), ndipo ziyenera kulembedwa pa "sampling" zokopa, kusonyeza kusiyana.
(6) Pambuyo poyang'anitsitsa, chiwerengero cha zinthu zomwe zatsirizidwa, chiwerengero cha zowonongeka zomwe zingatheke, chiwerengero cha zowonongeka zomaliza ndi code yachilema ziyenera kudzazidwa molondola mu khadi lomwe likutsatira, ndikusainidwa ndi woyang'anira.
