I roto i te ao hangahanga matatau e tere whanake ana, ko te tika tonu te rohe matua. I tēnei rā, kua whakaritea he auaha hou hei whakahou i ngā paerewa ahumahi: ko te Precision Marble Three-Axis Gantry Platform, he mahi whakamiharo o te hangarau e whakakotahi ana i te pumau ā-roto o te karāhe taiao me te hoahoa miihini hou hei whakatutuki i te tika taumata-micron i whakaarohia i mua kāore e taea i roto i ngā tono ahumahi.
Te Pūtaiao kei Muri i te Pūmautanga
Kei te ngākau o tēnei peke hangarau he kōwhiringa rauemi ohorere: te karāhe tūturu. Ko te turanga māpere mīhini-tika 1565 x 1420 x 740 mm o te tūāpapa ehara i te mea he āhua hoahoa noa iho—he otinga pūtaiao hoki ki te wero tawhito o te pupuri i te pumau i roto i ngā pūnaha tino-tika. "Ko te iti rawa o te tauwehenga whānui wera o te karāhe (2.5 x 10^-6 /°C) me ngā āhuatanga whakamātao tino pai e whakarato ana i te turanga e ātete ana ki ngā huringa pāmahana taiao me ngā wiri miihini pai ake i ngā hanganga whakarewa tuku iho," te whakamārama a Tākuta Emily Chen, te miihini matua i te Precision Engineering Research Institute.
Ka hono tika tēnei painga ā-taiao ki ngā inenga mahi e tahuri ana ngā mahunga puta noa i ngā ahumahi. Ka tutuki i te tūāpapa te ±0.8 μm te auautanga—arā, ka taea te hoki ki tētahi tūranga me ngā rerekētanga iti iho i te roangaru o te mārama e kitea ana—me te ±1.2 μm te tika o te tūnga i muri i te whakatikatika, ka whakatakoto i tētahi paerewa hou mō ngā pūnaha whakahaere nekehanga.
Te Hiranga o te Hangarau i roto i te Nekehanga
Haunga tōna turanga pumau, kei roto i te hoahoa o te tūāpapa he maha ngā auahatanga motuhake. Kei te tuaka-X he pūnaha taraiwa-rua e whakakore ana i te whakarerekētanga torsional i te nekehanga tere-nui, ā, e tukuna ana e ngā tuaka-X me Y he 750 mm o te haere whai hua me te ≤8 μm te tika i ngā papa whakapae me ngā papa poutū. Mā tēnei taumata o te tika āhuahanga ka mau tonu te tika o ngā ara 3D uaua ahakoa i raro i te micron.
He tino pai te taurite o ngā āheinga nekehanga o te pūnaha i waenga i te tere me te tika. Ahakoa te āhua iti o tōna tere mōrahi o te 1 mm/s, he mea arotau mō ngā tono e hiahia ana ki te whakahaere pai me te matawai puhoi—he mea nui ake te tika i te nekehanga tere. I tetahi atu taha, mā te āheinga whakatere 2 G ka whakarite kia tere te tīmatanga-mutu, he mea nui mō te pupuri i te tere o te mahi i roto i ngā tukanga tirotiro tika.
Me te kaha kawenga 40 kg me te taumira 100 nm (0.0001 mm), ka honoa e te tūāpapa te āputa i waenga i te whakahaere moroiti ngāwari me te pakari o te ahumahi—he whānuitanga e whakaputa ana i te hiahia nui puta noa i ngā rāngai hangahanga.
Te Whakarerekē i ngā Ahumahi Tino Hira
Ko ngā pānga o tēnei putanga nui o te tika ka horapa puta noa i ngā rāngai hangarau teitei maha:
I roto i te hangahanga haurua-ira, ahakoa ngā hapa ine-nanomita ka taea te whakakore i ngā maramara, kei te huri te pumau o te tūāpapa i ngā tukanga tirotiro wafer me te whakatikatika whakaahua. "Kei te kite mātou i te pikinga o ngā reiti kitenga hapa mā te 37% i ngā whakamātautau tuatahi," te pūrongo a Michael Torres, he miihini tukanga matua i tētahi kaihanga taputapu haurua-ira matua. "Kua whakakorea e te whakaiti wiri o te turanga māpere te wiri iti i huna i ngā āhuatanga o raro iho i te 50 nm i mua."
Ko tētahi atu painga ko te hanga whatu tino tika. Ko ngā tukanga whakakanapa me te huihuinga karāhe, i mua he maha ngā hāora o te whakatikatika ā-ringa, ka taea te whakahaere aunoa mā te whakanoho i raro i te micron o te tūāpapa, ka whakaiti i ngā wā whakaputa me te whakapai ake i te ōritetanga o te mahi whatu.
I roto i te rangahau hauora, kei te āhei te tūāpapa ki te whakatutuki i ngā putanga hou i roto i te whakahaere pūtau-kotahi me te whakaahua moroiti teitei. E kī ana a Tākuta Sarah Johnson o te Tari Hangarau Hauora o Stanford, "Mā te pumau ka taea e tātou te aro tonu ki ngā hanganga pūtau mō ngā wā roa, me te hopu i ngā whakaahua wā-roa e whakaatu ana i ngā tukanga koiora i hunahia i mua e te nekenekehanga taputapu."
Ko ētahi atu tono matua ko ngā mīhini ine taunga tino tika (CMM), te takai hikohiko moroiti, me ngā taputapu rangahau pūtaiao matatau—ngā wāhanga katoa e aro ana te huinga ahurei o te tino tika, te pumau, me te kaha kawenga ki ngā herenga hangarau kua roa e mau ana te hononga o te tūāpapa ki te tino tika, te pumau, me te kaha kawenga.
Te Anamata o te Hanganga Tino Tika
I te mea kei te haere tonu te mahi hanga ki te whakaitiiti me ngā paerewa mahi teitei ake, ka kaha ake te hiahia mō ngā pūnaha tūnga tino tika. Ko te Precision Marble Three-Axis Gantry Platform ehara i te mea he whakapainga piki haere noa iho engari he panonitanga nui ki te whakatutukitanga o te tika—te whakamahi i ngā āhuatanga rauemi taiao me te hangarau matatau kaua ki te whakawhirinaki anake ki ngā pūnaha utu hohe matatini.
Mō ngā kaihanga e whakatere ana i ngā wero o te Ahumahi 4.0, ka tukuna e tēnei tūāpapa he tirohanga ki te heke mai o te hangarau tika. He heke mai tēnei e memeha haere tonu ai te rārangi i waenga i te "tika taiwhanga" me te "hanga ahumahi", ka taea ai ngā auahatanga ka hanga i ngā mea katoa mai i ngā hikohiko o te whakatipuranga e whai ake nei ki ngā taputapu hauora whakaora ora.
E ai ki tētahi kaitātari ahumahi: "I te ao o te hanga tino tika, ehara te pumau i te āhuatanga noa iho—ko te pūtake tēnei e hangaia ai ngā whanaketanga katoa. Kāore tēnei tūāpapa e whakaara ake noa i te pae; ka hanga anō hoki i te katoa."
