Ngā painga o ngā irahiko karāhe
1: Nā te uaua haere o te āhua o te pokepokea ai, me te kanorau o ngā tono hua, kua piki haere ngā whakaritenga mō te tika o te tukunga o te mīhini mura. Ko ngā painga o ngā irahiko karāhe he māmā ake te tukatuka, he tere tango teitei o te miihini tukunga hiko, me te iti o te ngaronga karāhe. Nō reira, ka whakarērea e ētahi kiritaki mīhini mura rōpū ngā irahiko parahi, ka huri ki ngā irahiko karāhe. Hei tāpiri, kāore e taea te hanga i ētahi irahiko āhua motuhake ki te parahi, engari he māmā ake te hanga i te karāhe, ā, he taumaha ngā irahiko parahi, ā, kāore e pai mō te tukatuka i ngā irahiko nunui. Nā ēnei āhuatanga kua meinga ētahi kiritaki mīhini mura rōpū ki te whakamahi i ngā irahiko karāhe.
2: He māmā ake te tukatuka i ngā irahiko karāpiti, ā, he tere ake te tere tukatuka i ngā irahiko parahi. Hei tauira, mā te whakamahi i te hangarau mira hei tukatuka i te karāpiti, e 2-3 ngā wā tere ake te tere tukatuka i ētahi atu tukatuka whakarewa, ā, kāore e hiahiatia he tukatuka ā-ringa tāpiri, engari me huri ā-ringa ngā irahiko parahi. Waihoki, ki te whakamahia he pokapū miihini karāpiti tere-teitei hei hanga i ngā irahiko, ka tere ake te tere, ka teitei ake te whai hua, ā, kāore he raruraru puehu. I roto i ēnei tukanga, mā te whiriwhiri i ngā taputapu me te pakeke me te karāpiti e tika ana ka taea te whakaiti i te kakahu taputapu me te kino o te parahi. Ki te whakatauritehia te wā mira o ngā irahiko karāpiti me ngā irahiko parahi, he 67% te tere ake o ngā irahiko karāpiti i ngā irahiko parahi. I roto i te miihini tuku hiko whānui, he 58% te tere ake o te tukatuka o ngā irahiko karāpiti i ngā irahiko parahi. Mā tēnei, ka tino whakaitihia te wā tukatuka, ā, ka whakaitihia hoki ngā utu hanga.
3: He rerekē te hoahoa o te hiko karāpeti i tērā o te hiko parahi tuku iho. He rerekē ngā utu mō te whakakoi me te whakaoti i ngā hiko parahi i roto i te nuinga o ngā wheketere pokepoke, engari he tata rite tonu ngā utu mō ngā hiko karāpeti. Ka whakaitihia te maha o ngā mahi CAD/CAM me te tukatuka mīhini. Nā tēnei anake, he nui hei whakapai ake i te tika o te kōhao pokepoke.
Ae, i muri i te hurihanga o te wheketere pokepokea mai i ngā irahiko parahi ki ngā irahiko karāpiti, ko te mea tuatahi me mārama ko te whakamahi i ngā rauemi karāpiti me te whakaaro ki ētahi atu āhuatanga e pā ana. I ēnei rā, ko ētahi o ngā kaihoko o te mīhini mura ā-rōpū e whakamahi ana i te karāpiti hei mīhini tuku i te irahiko, ka whakakorea te tukanga o te whakakanapa i te kōhao pokepokea me te whakakanapa matū, engari ka tutuki tonu te mutunga o te mata e tumanakohia ana. Ki te kore e whakanuia te wā me te tukanga whakakanapa, kāore e taea e te irahiko parahi te whakaputa i tētahi mea mahi pēnei. Hei tāpiri, ka wehea te karāpiti ki ngā taumata rerekē. Ka taea te whakatutuki i te pānga tukatuka tino pai mā te whakamahi i ngā taumata tika o te karāpiti me ngā tawhā tuku mura hiko i raro i ngā tono motuhake. Mena ka whakamahia e te kaiwhakahaere ngā tawhā rite ki te irahiko parahi i runga i te mīhini mura e whakamahi ana i ngā irahiko karāpiti, kāti me pouri te hua. Mena kei te hiahia koe ki te whakahaere tika i te rauemi o te irahiko, ka taea e koe te whakatakoto i te irahiko karāpiti ki te āhua kore-ngaro (ngaronga iti iho i te 1%) i te wā o te mīhini taratara, engari kāore te irahiko parahi e whakamahia.
Kei te karāpiti ngā āhuatanga kounga teitei e kore e taea te whakataurite ki te parahi:
Tere tukatuka: e 3 ngā wā tere ake te miihini mira tere-rahi i te parahi; e 5 ngā wā tere ake te whakaoti mira tere-rahi i te parahi
He pai te mahi miihini, ka taea te whakatutuki i te whakatauira āhuahanga matatini
He māmā te taumaha, he iti iho i te 1/4 o te parahi te matotoru, he ngāwari te whakapiri i te hiko
ka taea te whakaiti i te maha o ngā irahiko takitahi, nā te mea ka taea te whakakotahi ki roto i tētahi irahiko whakakotahi
He pai te pumau o te wera, kāore he rerekētanga, ā, kāore he pakaru tukatuka
