He mea rongonui mō tōna tae pango motuhake, he hanganga matotoru ōrite, me ngā āhuatanga tino pai—tae atu ki te ātete ki te waikura, te ātete ki ngā waikawa me ngā kawakore, te pumau kore e rite, te pakeke teitei, me te ātete ki te kakahu—he mea nui ngā pereti mata kirikiri hei turanga tohutoro tika i roto i ngā tono miihini me te ine taiwhanga. He mea nui te whakarite kia tutuki i ēnei pereti ngā paerewa āhuahanga me ngā paerewa āhuahanga tika mō te mahi. Kei raro nei ngā tikanga paerewa mō te tirotiro i ā rātou whakaritenga.
1. Tirotiro Matotoru
- Utauta: He caliper vernier, he 0.1 mm te whānui o te pānui.
- Tikanga: Inehia te matotoru i waenganui o ngā taha e whā.
- Aromatawai: Tātaihia te rerekētanga i waenga i ngā uara mōrahi me ngā uara iti rawa i inehia i runga i te pereti kotahi. Koinei te rerekētanga matotoru (te rerekētanga nui rawa rānei).
- Tauira Paerewa: Mō tētahi pereti me te matotoru kua tohua o te 20 mm, ko te rerekētanga e whakaaetia ana kei roto i te ±1 mm.
2. Tirotiro i te Roa me te Whānui
- Utauta: He rīpene rino, he rūri rānei, he 1 mm te whānui o te pānui.
- Tikanga: Inehia te roa me te whānui i runga i ngā rārangi rerekē e toru. Whakamahia te uara toharite hei hua whakamutunga.
- Kaupapa: Te tuhi tika i ngā inenga mō te tatau i te rahinga, me te manatoko i te tutuki o ngā rahinga kua tonoa.
3. Tirotiro Papatahi
- Utauta: He mata whakahāngai tika (hei tauira, he mata whakahāngai maitai) me ngā inenga wiri.
- Tikanga: Whakatakotoria te taha hāngai ki te mata o te pereti, tae atu ki ngā taha whakarara e rua. Whakamahia te ine ine hei ine i te āputa i waenganui i te taha hāngai me te mata o te pereti.
- Tauira Paerewa: Ko te rerekētanga papatahi mōrahi e whakaaetia ana ka taea te tohu ko te 0.80 mm mō ētahi taumata.
4. Tirotiro Tapawhā (Koki 90°)
- Utauta: He rūri koki maitai 90° tino tika (hei tauira, 450×400 mm) me ngā inenga whāwhā.
- Tikanga: Whakatakotoria te rūri koki ki te kokonga o te pereti. Inehia te āputa i waenganui i te taha o te pereti me te rūri mā te whakamahi i te ine whāwhā. Whakahokia tēnei tukanga mō ngā kokonga e whā.
- Aromatawai: Ko te āputa nui rawa i inehia e whakatau ana i te hapa tapawhā.
- Tauira Paerewa: Hei tauira, ko te ātete rohe e whakaaetia ana mō te peka koki ka tohua pinepinetia ko te 0.40 mm.
Mā te piri ki ēnei tikanga tirotiro tika, paerewa hoki, ka oati ngā kaihanga ka tukuna e ia pereti mata karāhe te tika āhuahanga me te mahi pono e hiahiatia ana mō ngā mahi ine nui i roto i ngā ahumahi o te ao.
