Ngā āhuatanga ā-pūkaha taketake o ngā rauemi whakarewa

Ko ngā āhuatanga o ngā rauemi whakarewa e wehea whānuitia ana kia rua ngā wāhanga: te mahi tukatuka me te mahi whakamahinga. Ko te mea e kiia nei ko te mahi tukatuka e pā ana ki te mahi a ngā rauemi whakarewa i raro i ngā tikanga tukatuka makariri me te wera kua tohua i te wā o te tukanga hanga o ngā wāhanga miihini. Ko te kounga o te mahi tukatuka o ngā rauemi whakarewa e whakatau ana i tōna urutau ki te tukatuka me te hanga i te wā o te tukanga hanga. Nā te rerekētanga o ngā āhuatanga tukatuka, he rerekē anō hoki ngā āhuatanga tukanga e hiahiatia ana, pērā i te mahi whakarewa, te āheinga whakarewa, te āheinga hanga, te mahi maimoatanga wera, te āheinga tapahi, me ētahi atu. Ko te mea e kiia nei ko te mahi e pā ana ki te mahi a ngā rauemi whakarewa i raro i ngā tikanga whakamahinga o ngā wāhanga miihini, tae atu ki ngā āhuatanga miihini, ngā āhuatanga ā-tinana, ngā āhuatanga matū, me ētahi atu. Ko te mahi o ngā rauemi whakarewa e whakatau ana i tōna whānuitanga o te whakamahinga me te roa o te ora ratonga.

I roto i te umanga hanga mīhini, ka whakamahia ngā wāhanga mīhini whānui i roto i te pāmahana noa, te pēhanga noa me te kore e kaha te waikura, ā, i te wā e whakamahia ana, ka rerekē ngā kawenga ka pikauhia e ia wāhanga mīhini. Ko te kaha o ngā rauemi whakarewa ki te ātete i te kino i raro i te kawenga ka kiia ko ngā āhuatanga mīhini (ngā āhuatanga mīhini rānei). Ko ngā āhuatanga mīhini o ngā rauemi whakarewa te pūtake matua mō te hoahoa me te whiriwhiri rauemi o ngā wāhanga. I runga i te āhua o te kawenga e pā ana (pēnei i te kume, te pēhanga, te takahuri, te pānga, te kawenga huringa, me ētahi atu), ka rerekē anō hoki ngā āhuatanga mīhini e hiahiatia ana mō ngā rauemi whakarewa. Ko ngā āhuatanga mīhini e whakamahia whānuitia ana ko: te kaha, te kirihou, te pakeke, te pakari, te ātete pānga maha me te rohe ngenge. Ka matapakihia motuhaketia ia āhuatanga mīhini i raro nei.

1. Kaha

Ko te kaha e pā ana ki te kaha o te rauemi whakarewa ki te ātete i ngā kino (te nui rawa o te whakarerekētanga kirihou, te whati rānei) i raro i te kawenga pumau. Nā te mea ka mahi te kawenga i roto i te ahua o te kume, te pēhi, te piko, te kutikuti, me ētahi atu, ka wehea hoki te kaha ki te kaha kume, te kaha pēhi, te kaha piko, te kaha kutikuti, me ētahi atu. He maha ngā wā he whanaungatanga i waenga i ngā kaha rerekē. I te whakamahinga, ko te kaha kume te mea e whakamahia whānuitia ana hei taupū kaha taketake.

2. Te Kirihoutanga

Ko te kirihou e pā ana ki te kaha o tētahi rauemi whakarewa ki te whakaputa i te whakarerekētanga kirihou (te whakarerekētanga pumau) me te kore e pakaru i raro i te kawenga.

3. Te pakeketanga

Ko te pakeketanga he ine i te pakeketanga, te ngawaritanga rānei o tētahi rauemi whakarewa. I tēnei wā, ko te tikanga e whakamahia whānuitia ana mō te ine i te pakeketanga i roto i te hanga ko te tikanga pakeketanga kōpikopiko, e whakamahi ana i tētahi kōpikopiko o tētahi āhua ā-ira hei pēhi ki roto i te mata o te rauemi whakarewa e whakamatautauria ana i raro i tētahi kawenga, ā, ka inehia te uara pakeketanga i runga i te nui o te kōpikopiko.
Ko ngā tikanga e whakamahia whānuitia ana ko te pakeketanga o Brinell (HB), te pakeketanga o Rockwell (HRA, HRB, HRC) me te pakeketanga o Vickers (HV).

4. Ngenge

Ko te kaha, te kirihou, me te pakeke i kōrerotia i mua ake nei he tohu mahi ā-pūkaha katoa o te konganuku i raro i te kawenga pūmau. Inaa, he maha ngā wāhanga mīhini e whakahaerehia ana i raro i te kawenga huringa, ā, ka puta te ngenge i ngā wāhanga i raro i ēnei āhuatanga.

5. Te pakari o te pānga

Ko te kawenga e pā ana ki te wāhanga mīhini i te tere tino tiketike ka kiia ko te kawenga pānga, ā, ko te kaha o te konganuku ki te ātete i te kino i raro i te kawenga pānga ka kiia ko te pakari pānga.
