1. Te whakamau i te waiarikikia mau tonu te mahana o te pire i te wa katoa o te hanga.Te whakamau i te waiarikika whakamahia ki te tango painga o te kirihou teitei o etahi konganuku i te pāmahana tonu, ki te whiwhi hanganga me nga taonga motuhake.Ko te hanga isothermal e hiahia ana kia pupurihia te pokepokea me te pire kia rite tonu te mahana, he utu nui te utu, ka whakamahia noa mo nga mahi hangai motuhake me te pehi, penei i te hanga superplastic.

2. Te patupatuka taea te whakarereke i te hanganga whakarewa me te whakapai ake i te mahi whakarewa.I muriwera werako te ingot, ko te ahua o te maka taketake o te wewete, te pore, te kapiti moroiti ka whakakikihia, ka paiherea ranei;Ka pakaruhia te karaihe dendritic taketake kia pai ai te witi.I te wa ano, huri i te wehewehenga carbide taketake me te tohatoha koretake, kia rite te whakahaere, kia rite ki te whiwhi i te kiko o roto, te kakahu, te pai, te pai o te mahi matawhānui, te whakamahi pono o nga whaa.I muriwera weradeformation, he hanganga muka te whakarewa;Whai muri i te rerekeetanga o te matao, ka whakaatu nga tioata whakarewa i te raupapa.

3.te patupatukia rere te kirihou whakarewa me te hanga ki te ahua e hiahiatia ana o te mea mahi.Ko te rōrahi o te whakarewa kaore e rereke i muri i te rere o te kirihou na te kaha o waho, a ka rere tonu te whakarewa ki te waahanga iti rawa atu.I roto i te whakaputanga, ko te ahua o te mea mahi he maha tonu te whakahaere i runga i enei ture, a ka kitea te rerekeetanga o te tuhi whakapouri, reaming, piko me te tuhi hohonu.

4.tete hanga i tetahi mea mahihe tika te rahi, he pai ki te whakahaere o te hanga papatipu.Ka mate te hanga, Tangohanga, takahi me etahi atu tono o te rahi hanga i pokepokea he tika, me te pūmau.Ka taea te whakamahi i nga miihini hangai tino pai me te raina whakangao aunoa ki te whakarite i te hanga papatipu motuhake, te hanga papatipu ranei.

5.Ko te tukanga whakaputa ote patupatukei roto ko te whakaweti, te whakamahana me te maimoatanga o mua o te hanga papatea i mua i te hanga;Te maimoatanga wera, te horoi, te whakatikatika me te tirotiro i nga mea mahi i muri i te hanga.Ko nga miihini whakaipoipo e whakamahia ana he hama, he perehi waipēhi me te perehi miihini.He nui te tere o te paanga o te hama, he pai ki te rere kirihou whakarewa, engari ka puta te wiri;Ko te perehi hydraulic e whakamahi ana i te whakamaarama pateko, he pai ki te tarai i roto i te whakarewa me te whakahaere whakapai ake, he pumau te mahi, engari he iti te hua;Ko te perehi miihini kua mau te whiu, he ngawari ki te mohio ki te miihini me te miihini.

I nga ra kei mua, ko tehangarau hangahangaka whakapai ake i te kounga o roto ote hanga wahi, whakawhanake tikate patupatume te hangarau tapatapahi tika, whakawhanaketaputapu hangaahanga hangaraina ki te hua teitei me te tohu aunoatanga, whakawhanakehangahanga ngawarite hanga i te punaha, me te whakawhanake houhanga rauemiatukatuka maakatikanga.Hei whakapai ake i te kounga o roto owhakangao, ko te nuinga ki te whakapai ake i o raatau miihini (te kaha, te kirihou, te uaua, te kaha ngenge) me te pono.Me pai ake te tono o te ariā whakakino kirihou whakarewa;Te whakamahi i nga rauemi tino pai ake;Whakatikahia te whakamahana i mua i te whakamahana me te maimoatanga wera;He kaha ake, he nui ake hoki te whakamatautau kore kino mo nga mahi hangai.
