He mahi tino nui te whakatikatika arotahi kore mō ngā mīhini tapahi muka reiti. Mā te arotahi hē ka iti ake te kaha tapahi, ka taratara ngā taha tapahi, ka piri kino te paru, ā, ka kore e taea te tapahi i ngā rauemi. Kei roto i tēnei aratohu ngā tikanga whakatikatika taipitopito, ngaio hoki mō ngā mīhini tapahi muka reiti — te momo e whakamahia whānuitia ana i roto i te hanga ahumahi.
Ariā Matua: He aha te Hiranga o te Arotahi Kore mō te Tapahi?
- Arotahi Kore (Arotahi 0): Ko te pūwāhi e tūtaki ai te hihi taiaho ki tōna whānui tino pai me te kiato pūngao teitei rawa. Mō ngā rauemi pēnei i te maitai waro, ko te mata o te mea mahi ka tū ki te arotahi kore kia tika ai ngā kokonga me ngā taha tapahi maeneene.
- Te Whakakore Arotahi Pai: Kei roto i te mea mahi te pūwāhi arotahi. He pai mō te tapahi i ngā pereti matotoru, te konumohe, te maitai kore waikura, me ētahi atu, nā te mea he roa ake te kaha e whakamahia ana hei whakakore i te paru.
- Te Whakakore Arotahi Kino: Kei runga ake i te mata o te mea mahi te pūwāhi arotahi. Kāore i te tino whakamahia, engari i ētahi wā ka whakamahia ki ngā pereti angiangi, ki ngā rauemi motuhake rānei hei ārai i te wera o te taha o muri.
Tuatahi, me kimi e tātou te pūwāhi arotahi kore tika, kātahi ka whakatika i te whakakore arotahi pai, kino rānei i runga i te rauemi.
Tikanga 1: Te Whakamahi i te Rakau Arotahi (Paerewa me te Tino Tika)
He pūkenga tēnei e taunakitia ana e ngā kaihanga taputapu ngaio katoa, ā, he pūkenga me matatau mā ngā kaiwhakahaere.
Ngā Hipanga:
1. Te Whakarite me te Haumaru:
- Me whakarite kia whakawetohia te mīhini.
- Mauria he mōhiti tiaki.
- Horoia te tokotoko arotahi me te pūwero hei tango i ngā paru, i ngā otaota rānei.
2. Tāutahia te Rakau Arotahi:
Whakauruhia te tokotoko arotahi ki roto i te kōhao whakairi motuhake mō te pane taiaho. Ko te roa paerewa o te tokotoko arotahi he rite ki te roa arotahi o te pane taiaho (hei tauira, ko te roa arotahi 50mm e rite ana ki te tokotoko arotahi 50mm).
3. Nekehia te Upoko Taiaho:
Whakamahia te papa whakahaere hei whakanoho i te pane taiaho ki runga ake i te pereti hei tapahi.
4. Whakahaerehia te Arotahi:
Kimihia te kī mahi "Arotahi" (he ata, he kōwhiringa tahua rānei te nuinga) i runga i te papatohu whakahaere. Pēhia, ā, ka heke aunoa te pane taiaho.
Ina pā noa te pito o te tokotoko arotahi ki te mata o te pereti, ka tū te pane taiaho ka piki paku (he nui noa iho hei whakahoki i te tokotoko arotahi). I tēnei wā, ka tuhia aunoatia te tūranga arotahi kore e te pūnaha whakahaere, ā, ka whakatakotoria ki te mata o te mea mahi.
5. Hokihia te Rakau Arotahi:
Hokihia ā-ringa te tokotoko arotahi ki runga hei karo i ngā tukinga i te wā e tukatuka ana.
Ngā Painga: Tere, tika, aunoa, ā, he pai mō te pupuhi.
Tikanga 2: Tikanga Waro ā-Ringa (Tikanga Pereti Piki) – Manatoko Pūtaiao me te Whakatikatika Pai
Ko te paerewa koura mō te kimi i te arotahi tino pai, inā koa ina whakakapia ngā karāhe arotahi, ina whakapaehia he hē te arotahi, ina arotau rānei i te arotahi mō ngā rauemi hou.
Ngā Hipanga:
1. Waihangahia he pari:
Tangohia he wahi para o te rauemi kotahi me te mea mahi.
Whakaarahia tetahi pito (hei tauira, me tētahi atu poraka para) hei hanga i tētahi pari maeneene me te koki o te 10-15 nekehanga.
2.Tautuhia ngā Tawhā Tapahi:
I roto i te pūnaha CNC, tuhia he rārangi roa, tika (tata ki te 10cm) mai i te pito o raro ki te pito o runga o te pari. Whakatakotoria he kaha tapahi pumau, he tere hoki (tirohia ngā tawhā mō ngā rauemi he rite te matotoru i roto i te whare pukapuka rauemi).
3. Mahi i te Tapahi:
Nekehia te pane taiaho ki te pito o raro rawa o te pari ka tīmata te tapahi.
Tukua te rēseri kia haere i te rārangi mai i raro ki teitei. I te mea ka huri tonu te teitei o te pereti, ka neke te arotahi rēseri kia rite.
4. Mātakihia, Tātarihia hoki te Kerf:
I muri i te tapahi, me ata tirotiro te kakau katoa.
Ka rerekē te whānui o te kerf—tāutuhia te wāhanga whaiti rawa, tino pai rawa. Ko te teitei o te pereti e rite ana i tēnei tūranga te arotahi tino pai mō te rauemi i raro i ngā tawhā o te au!
5. Ine me te Tuhi:
Whakamahia he ine teitei, he caliper rānei hei ine i te teitei mai i tēnei "pūwāhi tino pai" ki te papa (H1).
Inehia te teitei mai i te turanga pari (te mata tohutoro arotahi kore) ki te papa (H2).
Te tauwehenga arotahi tino pai = H1 – H2.
Tuhia tēnei āputaputa ki roto i tō whare pukapuka tawhā tukanga tapahi. Mō ngā tapahi ā muri ake nei o taua rauemi anō, tāpirihia tēnei āputaputa ki te arotahi kore i whakatakotoria e te tokotoko arotahi.
Tikanga 3: Te Pūoko Whakapā o te Pūwero (He mea noa i roto i ngā Pūnaha CNC Hou)
He maha ngā mīhini tapahi taiaho hou e whakauru ana i te arotahi aunoa, e whakamahi ana i te pūoko hei pūoko.
Ngā Hipanga:
1. Tīpakohia te mahi "Arotahi Aunoa" i te papatohu whakahaere.
2. Ka whakahaerehia e te pūnaha te hekenga mārire o te pane taiaho kia pā mārire te pito o te pūwero ki te mata o te pereti.
3. Ina pā atu, ka ara aunoa te pane taiaho mā te uara utu kua whakaritea (uara utu = te tawhiti mai i te pūwero ki te arotahi kore – te teitei o te pūwero).
4. Ina mutu te hiki, ka tika te whakanoho o te arotahi kore ki runga i te mata o te mea mahi.
Kia mōhio: Ko tēnei tikanga e hiahia ana kia mau tonu te pūwero, kia kore e whakapohehetia, me ngā tautuhinga tika o te "teitei o te pūwero" me te "uara utu" i roto i ngā tawhā pūnaha.
Tikanga 4: Te Tirotiro Māmā i te Hiko (Tikanga Wheako o ngā Kaiwhakahaere Hōia)
He tikanga whakatau tere ā-wheako mō ngā āhuatanga kāore e wātea ana ngā tikanga o runga ake nei, ā, e hiahia ana ki te wheako mahi.
Ngā Hipanga:
1. Mahi i te mahi wero i ngā rauemi para.
2. Mātakitaki marietia te tauira mura i te wā e werohia ana!
- Arotahi tika: He mura kaha, kukū e pupuhi poutū ana ki raro, he iti noa te peka, ā, he oro koi.
- Te arotahi nui rawa atu (te whakaiti i te arotahi pai): He mura marara, he ngoikore e tauhiuhi ana.
- He iti rawa te arotahi (he kore arotahi kino): He mura kua marara, ā, tera pea ka poto ake te āhua.
3. Whakatikatikahia te teitei o te arotahi i runga i te tauira mura kia tino kukū, kia poutū hoki ngā mura.
Kia mōhio: He nui te awe o te rauemi, te hau, me te mana ki tēnei tikanga, ā, me whakamahi noa hei whakatau āwhina.
Whakarāpopototanga me te Taunakitanga mō te Tukanga Whakahaere
Mō ngā mahi o ia rā, whai i tēnei tukanga mahi:
1. Whai muri i te tīmatanga o ia rā: Whakamahia te Tikanga 1: Focus Rod mō te whakatikatika arotahi kore taketake—he tere, he tika hoki mō ngā mahi o ia rā.
2. Whai muri i te whakakapinga o ngā wāhanga matua, ngā rauemi rānei: Whakamahia te Tikanga 2: Tikanga Pereti Piko hei manatoko me te whakatikatika kia kitea ai, kia tuhia ai hoki te taurite arotahi tino pai mō te rauemi.
3. I te wā e tapahi ana: Hei aroturuki āwhina, whakamahia te Tikanga 4: Tirohanga Hiko i ētahi wā hei tirotiro tere i te pumau o te arotahi.
Hei whakamutunga, tirohia tonu te Pukapuka Whakahaere o tō mīhini. Tērā pea he rerekētanga iti o ngā mahi arotahi me ngā mahi whakahaere motuhake o ngā waitohu me ngā tauira rerekē o ngā mīhini tapahi taiaho. Kei roto i te pukapuka te aratohu tino whai mana.
Mō ētahi atu otinga tapahi taiaho ngaio, tautoko hangarau rānei, tēnā whakapā mai ki tā mātou tīma!
