Kua kite pea te hunga kua roa e mahi ana i te taiwhanga ine ine i te tauira kotahi: ko ngā mīhini tawhito kei runga i ngā moenga rino maka, ko ngā mea hou kei runga i te kōhatu pango. Kāore i puta taua nekehanga nā te mea he ātaahua ake te āhua o te karāhe i raro i ngā rama. I puta tēnei nā te mea he raruraru ahupūngao kāore i te tino ataahua - te whakawhanuitanga wera.
Ka whānui, ka whakawhāiti te rino maka i te 10-12 x 10⁻⁶ ia °C. He iti noa iho te ahua o tēnā tae noa ki te wā e whakatakotoria ai ki te taha o te karāhe tūturu, e tata ana ki te 5-8 x 10⁻⁶ ia °C, ā, i roto i ētahi karāhe pango matotoru e tata ana ki te 4-5 x 10⁻⁶. I runga i te papa ine 1-mita, ka taea e te nekehanga 1°C o te pāmahana taiao te neke i te mata o te rino maka mā te maha o ngā maikorona neke atu i te karāhe ōrite. Mō te ātete papa awheawhe, kāore he tangata e māharahara. Mō te CMM e tirotiro ana i te atamira wafer semiconductor, i te interferometer laser rānei e pupuri ana i te sub-micron repeatability, ko taua rerekētanga te kēmu katoa.
He rite te hiranga o te whakaiti i te hiranga o te whakawhānui
Ko te pumau wera te mea e arohia ana, engari ko te whakaiti i te wiri he mea nui tonu pea mō ngā mahi nekehanga tino tika - te tango me te whakanoho i ngā pane, ngā wāhanga XY, ngā papaaho hau. He mea whakakotahi te karāhe, ehara i te mea whakarewa ōrite, nō reira kāore te wiri ā-pūkaha e horapa mā roto i te rino maka. Ka marara, ka mimiti hoki ngā rohe kōpaka o roto i te pūngao, kaua e tuku mā te ma. I roto i te mahi, ko te tikanga o tēnei heturanga karāheka tere ake te tau i muri i te mutu o te nekeneke o te tuaka mīhini, ka poto ake te wā noho me te nui ake o te kaha mahi i ngā raina tirotiro me te huihuinga.
Kei reira anō te take mō ngā mea ka tupu i roto i te wā roa. Ka taea e ngā papa rino maka, ahakoa ngā mea kua whakaitihia te ahotea, te ngokingoki haere i roto i ngā tau i te mea ka tohatohahia anō ngā ahotea o roto. Nā te mea kua hangaia te karāneti i raro i te pēhanga taiao nui i roto i te wā whenua, kāore he raruraru pērā - ehara i te "tau" pērā i te whakarewanga.
Kāore i te rite katoa te karāhe
Koinei te wāhanga e whakararuraru ana i te tini o ngā kaihoko. Ka hokona te karāneti i runga i te matotoru me te tae, pērā i te hoko rakau i runga i ngā momo, engari he rerekē te mahi ā-tinana i waenga i ngā keri. Ko te kōhatu iti te matotoru, te rauemi rānei he uaua kitea me te momo kakano kāore i te ōrite, e kore e mau te papatahi i roto i te wā rite ki te karāneti pango matotoru, pai te kakano i roto i te awhe 2,900-3,100 kg/m³. I ētahi wā ka whakakapia te māpere e ngā kaiwhakarato iti ake nā te mea he iti ake te utu me te ngāwari ki te mīhini, engari he toka waro-whakaahua te māpere - he ngohengohe ake, he nui ake te pūngao, ā, he iti ake te pumau o te taha i te karāneti tūturu. Mō te papa whakapaipai, kāore he aha. Mō te pereti mata ka tohua e te CMM probe mano ngā wā i te rā, he mea nui, ā, ko tētahi o ngā huarahi e whakaitihia ana e ngā kaihoko me te kore e mōhio kia puta rā anō te rerekētanga whakatikatika i muri i ngā marama.
Te wāhi e kitea ai tēnei i roto i te mahi
Ko te huri ki ngā turanga karāhe ka kitea nuitia i roto i ngā taputapu tirotiro haurua-ira, ngā pūnaha keri PCB me ngā pūnaha AOI, ngā mīhini ine taunga-toru, ngā whakatakotoranga ine whakawhiti-reera, me te piki haere o te hanga pākahiko me ngā whatu tika, kua noho te tūnga iti-micron hei whakaritenga taketake kaua hei whakaritenga papai. I te mea kei te whakawhāiti haere tonu ngā manawanui puta noa i ēnei ahumahi — e akiakihia ana e ngā pona maramara iti ake, ngā paparanga pākahiko angiangi ake, me ngā pūnaha reera tere ake — ka nui haere te āputa i waenga i te rino maka "pai" me te karāhe pumau te rahi, kāore e iti iho.
Mena he whakaaro kotahi mā ngā kaihangarau e whakatau ana i tētahi tūāpapa tika hou, koia tēnei: pātaihia ngā tatauranga matotoru me te whānui o te wera, kaua ko te "kirinite" anake hei rauemi tirotiro. Ko te rerekētanga i waenga i tētahi kirinite matotoru kua whiriwhiria pai me tētahi whakakapinga iti ake te kounga ko te rerekētanga i waenga i tētahi mīhini e pupuri ana i te whakatikatika mō te tekau tau me tētahi e hiahia ana kia whakatikatikahia anō i ia hauwhā.
