Kei te takoto tō pereti mata.
Kāo, kāore i āta whakatau kia tinihangatia koe. Engari, ki te mea he rino maka, ā, kua whakamahia e koe taua tuaka-5 i te ata katoa me te tauhiuhi o te wai whakamatao ki ngā wāhi katoa, tera pea kāore te inenga e whiwhi ana koe i rite ki tāu i whakaaro ai.
Koinei te mea e tupu ana: ka mimiti te rino maka i te makuku, ka tauhohe ki ngā wai whakamatao wai, ā, ka tīmata te waikura mai i te wā ka mutu te paninga hinu. Ahakoa i roto i ngā toa maroke, ka puta te whānui me te whakawhāiti tonu i ngā huringa pāmahana. Whakatakotoria he wāhanga tika ki runga i taua pereti i te 8 i te ata i te wā e mātao ana te toa, kātahi ka tirohia te wāhanga kotahi i te 2 i te ahiahi i muri i te oma o ngā mīhini mō ngā hāora—tērā pea kāore ngā tau e ōrite. Ā, ki te mea kei te whakaaro koe he aha i kore ai tō CMM e angitu i ngā rangahau kaha ahakoa ngā āhuatanga ōrite, ko ō mata tohutoro pea te take puku.
Kāore he raruraru o ngā taputapu ine karāhe.
Ehara i te mea he makutu. Engari ko te tauwehenga whānui wera o te karāhe kei te 4.5 × 10⁻⁶/°C—tata ki te hautoru o te rino maka. I runga i te whānui 600mm, ka puta he panoni āhua 0.001mm pea i runga i te karāhe i te pāmahana 5°C, ā, ka rerekē pea te rahi o te karāhe i te 0.001mm, ki te 0.012mm, ki te rino maka rānei. I roto i te miihini tika, ina whawhai koe mō ngā manawanui 0.005mm, koia te rerekētanga i waenga i te paahitanga me te para.
I rongo ahau i tētahi toa i whakawhiti i tā rātou mata tirotiro matua mai i te rino maka ki te karāhe, ā, i kite tonu ahau i te hekenga o te tere o te para—ehara i te mea nā te pai haere o ā rātou mīhini, engari nā te mea kua kōrerotia te pono e tā rātou pūnaha ine.
Ko te mea whakamīharo mō te karāhe, ā, kāore i te tino kōrerohia mō tēnei, ko tōna āhua e ārai ai i ngā kino.
Ka taka he poraka ine ki runga i te pereti rino maka? Tērā pea ka ara ake he kōhao. Kei te tū whakahīhī taua āhua iti nei ki te mata, ā, inaianei kei te hē te ine o ia wahi ka tirohia e koe ki taua wāhi. Kāore he whakatūpato, kāore he tohu e kitea ana—he hapa kei te kohikohi puku noa.
Ka pā te ine kotahi ki te karāhe? Ka pakaru. He poka iti pea. Engari koinei te mea—kei te papatahi tonu te toenga o te mata. Ka taea e koe te whakamahi i te wāhi kāore i pakaru me te māia. Kei te rohe tonu te hapa, ā, e kitea ana, kāore e huna, e horapa ana rānei.
Nui atu te hiranga o tēnei i tā te tangata e whakaaro nei i roto i ngā taiao whakaputa e tukinotia ana ngā pereti mata i ia rā, i ia rā.
Ko te nekehanga wera te kaipatu puku i roto i te miihini tika.
Whakaarohia tēnei: kei te whakahaere koe i tētahi mahi i tētahi ata Mane. Ko te pāmahana o te toa he 18°C. Ka tirohia e tō kaimahi whakarite ngā āhuatanga matua katoa, he pai te āhua o ngā mea katoa, kei te oma ngā wāhanga. Kātahi ka tae mai te ahiahi o te Paraire, ā, ka puta whakarere mai te tohunga QC i ngā wāhanga i pai te noho mō te wiki katoa. He aha te mea i rerekē? Kāore ngā mīhini i rerekē. Kāore ngā kaiwhakahaere i rerekē. Engari i rerekē te pāmahana o te taiao—e 4, e 5 rānei ngā nekehanga i te mea e raru ana te pūnaha HVAC i ngā āhuatanga o te mutunga wiki, i te mea rānei e neke ana te rā, e whakamahana ana i tētahi taha o te whare.
Ka whānui, ka whakawhāiti hoki ngā pereti rino maka ki ēnei tūru. Kāore te karāneti e pērā.
Koia te take i whakamahia ai e ngā taiwhanga ine kounga teitei te karāhe anake mō ngā tekau tau. Ehara i te mea tuku iho—engari he tohutoro te karāhe e kore e rere ki te taiao.
Tētahi atu mea e warewarehia ana: te whakaiti i te wiri.
Ka wiri ngā pokapū mīhini hou. Ko ngā miro i te 15,000 RPM, ngā tere whakawhiti, ngā taputapu waipēhi—ka whakaputa katoa i te pūngao miihini e tuku ana i roto i te moenga mīhini, i roto i te papa, ki roto i tō pūnaha ine. I runga i te mata rino maka, ka mau tonu aua wiri. Ka wiri tō ngira tohu waea. Ka rerekē ō pānui mamati. Kei te ngana koe ki te pānui i te 0.001mm i te wā e wiri ana tō pūnaha katoa.
Ka mimiti te karāneti i taua pūngao. Ko tōna tauwehenga whakamātao taiao e tekau ngā wā teitei ake i te rino maka. He rite ki te whakatakoto i tō tautuhinga ine ki runga i te ārai ru. Ka tere ake te pumau o ngā tau, ka taea te tukurua i ngā panui, ā, ka taea e koe te whakawhirinaki ki tāu e kite nei.
Mena kei te whakaaro koe mō ngā tono tūturu, koinei pea te mea e pā ana ki a koe:
Ngā pereti mata mō te tirotiro me te tahora—te tirotiro i te papatahi, te whakarara, te tapawhā. Ko te nuinga o ngā toa e hiahia ana kia kotahi te pereti tohutoro pai mō tō rātou wāhi whakatū.
Ngā tapawhā matua mō te tirotiro i te poutū o te tuaka o tō CNC. Mena kei waho o te tapawhā tō mīhini, ka mau taua hapa i ia wāhanga e hangaia ana e koe. E rima meneti te roa o te whakahaere i tētahi tirotiro tapawhā-toru ia wiki, ā, ka hopukina ngā raruraru i mua i te huri hei raruraru wāhanga.
He poraka-V hei pupuri i ngā wāhanga porotaka i te wā e tirotirohia ana. He uaua te ine i te rakau porowhita kia rite tonu—mā ngā poraka-V ka ea tēnā.
He tapa tika mō te tirotiro i ngā ara mīhini me ngā mata nunui kāore e taea te whakatakoto pereti.
Ngā whakarara hei whakaara ake i ngā wāhanga mahi kia taea ai e koe te uru atu ki ngā āhuatanga e huna ana.
Kia tika te whakatau i ngā tohu: ko te nuinga o ngā mahi miihini tika me whiwhi i te Tohu 00. Mā tēnā ka taea e koe te aro ki te papatahi tata ki te 1.5 maikiromita ia mita. He ngoikore ake te Tohu 0 i te 4 maikiromita pea—he pai mō te tirotiro mata engari kāore mō te mahi piri. Ko te Tohu 000 he mea kounga taiwhanga, 0.5 maikiromita, pai ake rānei, ā, he nui rawa atu mēnā kei roto koe i te mahi whatu, i te mahi whakatikatika rererangi rānei.
Ko te ture e whakamahia ana e au: me kotahi, kia rua rānei ngā taumata tika ake o ō taputapu tohutoro i ngā ātete e ngana ana koe ki te pupuri. Mena ko tō ātete tukanga kino rawa atu ko ±0.02mm, ka hoatu e te pereti Tau 0 (ātete tata ki te 0.004mm/m) he tawhē pai ki a koe.
He māmā noa te tiaki, ā, he pono, he ngāwari te whakamahi i te karāhe.
Puritia kia ma. Horoia i muri i te whakamahinga, inā koa mēnā kua whakamahia he wai tapahi. Whakamahia he kaihoroi kirikiri, he kaihoroi pereti mata rānei e tika ana, kaua e whakamahia he matū hoko noa. Tautokona ngā pereti nunui ki runga i ngā tūnga kua hangaia mō rātou—mēnā kāore i te tika te tautoko, ka piko ngā taha, ā, ka kino te papatahi o te pereti.
Me tuku tiwhikete anō i ia wā. Me tuku tiwhikete anō i ia tau mō ngā pereti e whakamahia nuitia ana, i ia rua tau mō ngā pereti iti te rahinga. Ehara i te mea utu nui, ā, ka hoatu he taunakitanga kua tuhia kei te pai tonu ō tohutoro.
Anei tētahi tīmatanga whai hua mēnā kei te hiahia koe ki te huri:
Tāutuhia tō mata tohutoro tino hira—ko te mea e whakamahia ana e koe mō te tirotiro whakamutunga i ō wāhanga tino pūmau. Koinei te wāhi e tino rerekē ai te karāhe.
Kātahi ka tirohia te tukanga tirotiro. Kei hea koe e moumou taima ana ki te whawhai ki ngā pānui koretake? Kei hea koe e whakapae ana kei te hapa te ine engari kāore e taea te whakaatu? Koinei ngā mea e tika ana mō ngā taputapu karāhe tuarua me tuatoru.
Kāore e hiahiatia kia whakakapia ngā mea katoa i te wā kotahi. Engari mā te whakawhiti i tētahi, i ētahi rānei pereti kī ka mōhio wawe koe mēnā he pai te haumi ki te karāhe i roto i tō mahi.
Ko te nuinga o ngā toa e whakawhiti ana kāore e hoki anō.
