I roto i te reo o te miihini miihini, ko te "kore-waku" he ariā pai - he mea e puta ana i roto i ngā tauākī rapanga pukapuka engari kāore i tino tutuki i te ao tūturu. Heoi, i roto i ngā wāhanga tūnga tika e neke ana i ngā anga silicon i roto i ngā mīhini lithography, ngā pūnaha laser tuhi-tika, ngā taputapu keri PCB tere-teitei, me ngā papa tirotiro nanometer-tauine, ka tata rawa ngā huānga nekehanga ki tēnei pai. Ka mahia e rātou tēnei mā te hangarau e kiia nei ko te whāriki hau, ā, ko te mata e eke ana taua kiriata angiangi o te hau he karāhe tino pai.
Ko te mārama ki te hangarau kawe hau — ōna āhuatanga ahupūngao, ōna whakaritenga, me ōna herenga — kāore e taea te wehe atu i te mārama he aha te karāhe te rauemi whiriwhiri mō ngā mata arataki kawe hau. He mahi tahi ngā hangarau e rua: mā ngā kawe hau ka taea te whakamahi i ngā āhuatanga mata tika o te karāhe, ā, mā te karāhe ka taea e ngā kawe hau te whakatutuki i te pumau me te tika o te tūnga e tika ai te whakamahi i a rātou i te tuatahi.
Te Ahupūngao o te Mahi Ā-Hau
Ka tautokona e te peera porotaka tuku iho — te peera pōro, te peera roera rānei — te kawenga e neke ana mā te pa Hertzian: ka pēhi ngā pōro, ngā roera rānei ki ngā ara reihi, ka paku rerekē te āhua i raro i te kawenga, ka tukuna te kaha mā te wāhi pa iti engari kāore i te kore. Ka puta te waku i tēnei pa, ka puta te kakahu, ā, ka hangaia he ara miihini e taea ai te tuku i te wiri mai i te peera ki te hanganga tautoko.
Ka whakakapia tēnei hononga totoka e te peera hau ki tētahi kiriata angiangi o te hau pēhanga — he hau pēhanga maroke, he ma te nuinga, ahakoa ka whakamahia te hauota i ngā tono e raru ana te nui o te makuku o te hau. Ka wehea te huānga neke (te "reti" te "kaata rānei") mai i te mata arataki e tētahi āputa he 5–15 maikiromita te whānui. Ka tukuna te hau pēhanga mā roto i ngā kōhao iti, i ngā mata pūwero rānei i te mata o te reti, ka rere ki roto i tēnei āputa, kātahi ka puta i ngā taha o te wāhi peera.
Ko te tohatoha pēhanga i roto i te āputa — teitei ake i te taha o ngā kōhao tuku, iti iho i te taha o te putanga — ka whakaputa i te kaha hiki kupenga e tautoko ana i te taumaha o te kawe (i roto i ngā whirihoranga whakapae) i te kawenga rānei. I te hekenga o te āputa (hei tauira, ki te piko paku te kawe i raro i te kawenga), ka piki ake te ātete rere, ka piki ake te pēhanga, ā, ka piki ake te kaha whakaora — ka hangaia he pūnaha pumau-ake. I tetahi atu taha, ki te piki ake te āputa, ka heke te pēhanga, ā, ka iti ake te pakari o te peera.
Ko te hua matua o tēnei tautoko kawenga kore-pā ko te tata korenga o te waku pūmau me te waku reti. He waku pūmau te āhua o tētahi atamira whāngai hau kua hoahoatia pai, ā, kāore e taea te ine — he kore noa iho i roto i te whakataunga o te nuinga o ngā pūnaha ine kaha. E whakaahuatia ana tēnei āhuatanga ko te korenga o te "waku" — te āhuatanga paheke-piri e tika ana kia hinga te waku pūmau (teitei ake i te waku nekeneke) kia tīmata ai te nekehanga, ka puta he wiri e whakararuraru ana i te tūnga o muri mai.
He aha te Hiranga o te Nekehanga Kore-Stick mō te Tūnga Tika
I roto i tētahi wāhanga tūnga tīwiri-pōro tikanga, tīwiri-ārahi rānei me ngā peera huānga hurihuri, ko te tūnga he herenga taketake ki te āheinga tūnga. Ina whakahaua e tētahi pūnaha whakahaere tūnga he nekehanga iti, me wikitoria tuatahi e te pūnaha taraiwa te waku tūmau i mua i te neke o te kāreti. Ko te tikanga o tēnei, kāore te tūranga i whakahaua me te tūranga tūturu i te ōrite i ngā rahi hikoinga iti — ka "piri" te wāhanga, kātahi ka "paheke", ka hipa i te tūranga i whakahaua i mua i te taunga.
Ka whakatakotohia e tēnei pānga he rohe iti iho i te rahi o ngā taahiraa me te whānui o te tūnga. I roto i ngā pūnaha servo, ka puta te huringa rohe i te stiction — he āhuatanga e whai tonu ana te koropiko whakahaere tūnga huri noa i te tūranga kua whakahaua, kāore e taea te whakatau ki tētahi uara pumau nā te mea me wikitoria te stiction i tētahi nekehanga whakatikatika, ka tukuna te atamira ki tua atu i te ūnga.
Ka whakakorea rawatia te piripono e ngā whāriki hau. Ka mānu te kāreti i runga i te kiriata hau tonu, ā, ko te kaha iti noa iho e pā ana ki te ahunga nekehanga ka puta he nekehanga ōrite. Ko te tikanga tēnei:
- Ka taea te whakatutuki i te tūnga taumata-nanomita mā te whakamahi i ngā tikanga taraiwa tika (ngā motuka raina, ngā kaiwhakaoho piezoelectric, ngā kaiwhakaoho koiri-reo rānei) me te kore e whai rohe iti iho i te rahi o ngā taahiraa e pā ana ki te mahi.
- Ka tino whakaitihia te wā taunga nā te mea kāore te porowhita whakahaere e kaha ki te whawhai i ia nekehanga.
- Ko te kaha o te tukuruatanga ka herea e te taumira o te encoder me ngā pānga wera, kaua e te rerekētanga o te waku.
Mō te whakaahua-ā-ira-haurua, me hikoi te wāhanga wafer ki ia tūranga mate me te āheinga tāruarua iti-nanometer i ngā putanga o ngā rau hikoinga ia hekona, he mea nui ēnei āhuatanga. Kāore he atu hangarau whāriki e whakarato ana i te mahi rite i tēnei wā i te tauine e hiahiatia ana.
Te Mata Arataki Granite: Te Whakahohe i te Mahi a te Peihana Hau
Ko te pai o te whāriki hau ko te mata anake e eke ana. Ko te āputa kiriata hau o te 5–15 μm ehara i te mea e whakaaetia ana mō te taratara o te mata aratohu — ko te āputa whakahaere katoa tae atu ki ngā pūtake rerekētanga katoa. Me maeneene ake, me papatahi ake te mata aratohu i tēnei āputa kia tika ai te mahi a te whāriki hau.
Ngā Whakaritenga Whakaotinga Mata (Pakari)
Me iti noa te taratara o te mata ārahi i te āputa hau.mata ārahimā te taratara Ra o te 0.4 μm (he mata mīhini pai rawa atu) ka puta he rerekētanga teitei ā-rohe e rite ana ki tētahi wāhanga nui o te āputa hau, ka puta he rerekētanga pēhanga pōrearea e whakamaoritia tika ana hei haruru tūnga i runga i te kawe.
Ko ngā mata arataki karāhe tino tika mō ngā tono kawe hau ka whakapirihia ki ngā uara Ra o te 0.02–0.1 μm (20–100 nm) — e rite ana ki ngā whakaotinga kounga whakaata. Ko te whakatutuki i ēnei uara taratara i runga i te karāhe me whai tikanga whakapiri motuhake, ngā mea whakakoi kounga teitei, me ngā kaiwhakahaere mohio e mārama ana ki ngā tikanga tango rauemi me te whanonga o te hanganga moroiti tioata o te karāhe i te wā whakapiri pai.
He mea nui te pakeke o te karāneti i konei: ka taea te whakapiripiri i tētahi kōhatu mārō ake, matotoru ake (pērā i te karāneti pango kounga teitei he ≈ 3,100 kg/m³ te matotoru) kia iti ake te taratara i te karāneti hina ngawari ake, te māpere rānei, nā te mea kāore tōna hanganga karaihe pai ake, piri rawa atu e kukume i ngā kongakonga witi e rakuraku ana i te mata i te wā e whakapiripirihia ana. Koinei tētahi o ngā take hangarau matua e hiranga ai te whiriwhiri rauemi mō ngā mata arataki e mau ana i te hau, ehara i te mea mō te whakatakotoranga papatahi ā-ao o te pereti mata anake.
Ngā Whakaritenga Papatahi me te Tika
Haunga te taratara o te mata, me tutuki i ngā mata arataki e mau ana i te hau ngā whakaritenga papatahi tino pakari. Ka "pānui" te kawe o te atamira kawe hau i te mata arataki — ko tōna aronga i ia pūwāhi i te haerenga ka whakatauhia e te āhua ā-rohe o te mata arataki. Ko te rerekētanga mai i te papatahi tino pai (i te ahunga Z) te tika rānei (i te ahunga poutū ki te nekehanga, i roto i te papa XY) o te mata arataki ka whakaputaina hei hapa nekehanga e rite ana o te kawe.
Koinei te āhuatanga e mōhiotia ana ko te hapa Abbe (te hapa sine rānei): mēnā he hapa pikinga o te mata ārahi he θ radians, ā, ko te pūwāhi e arohia ana i runga i te kawe kei te tawhiti L mai i te mata ārahi, ko te hapa tūnga taha ka puta ko L × sin(θ) ≈ L × θ mō ngā koki iti. Mō te kawe kei reira te kaikōwae ine me te wāhanga e inehia ana e wehea ana e te 100mm i te ahunga poutū, ka puta he hapa tūnga tata ki te 0.48 μm te hapa pikinga o te mata ārahi he 1 arcsecond.
Hei whakaiti i tēnei pānga, me whai mata ārahi he hapa tika kei roto i te awhe hekona āwhata, kei raro iho rānei, puta noa i te roanga haere katoa o te atamira. Mō te atamira haere 500mm, e rite ana tēnei ki ngā rerekētanga teitei o ētahi maikiromita, iti iho rānei puta noa i te roanga ārahi karāhe katoa. Hei whakatutuki me te manatoko i tēnei taumata tika, me whai tikanga whakapiri tika, me ine tupato ki ngā taumata hiko me ngā ine whakawhiti taiaho, me ngā tikanga whakatikatika waru e rite ana ki ērā e whakamahia ana mō te whakapiri pereti mata.
Te Pūngao me te Āheinga o te Hau
Ko tētahi āhuatanga o te karāhe he mea tino nui mō ngā tono kawe hau engari kāore i te tino kōrerohia i roto i ngā tuhinga whānui ko te porosity. Mena he pūwero tuwhera te mata o te karāhe ārahi — he āputa moroiti e hono ana i te roto o te kōhatu ki te mata — ka taea e te hau pēhanga i roto i te āputa kawe te turuturu ki roto i te kōhatu, kaua e rere ōrite ki te putanga kawe. Ka hangaia he tohatoha pēhanga kore taurite, ka piki ake te whakamahinga hau, ā, i ngā wā tino kino ka taea te hinga o te kawe i te rohe.
Ko te kirikiri pango matotoru-teitei, me tōna porosity tino iti i puta mai i tōna hanganga tioata matotoru, he iti ake te tūponotanga ki tēnei raruraru i ngā kirikiri hina matotoru-iti. Ko te kiato o te 3,100 kg/m³ - ki te whakataurite ki te kirikiri hina noa i te 2,600–2,700 kg/m³ - e whakaatu ana i te iti rawa o te āputa i roto i te rauemi. Mō ngā mata arataki e mau ana i te hau, ka pā tika tēnei rerekētanga o te porosity ki te mahi me te pumau o te peera.
I ngā whakamahinga nui, ka taea te whakamahi i ētahi atu maimoatanga mata (te whakakī korehau ki te epoxy, ngā tikanga whakapiri motuhake rānei hei kati i ngā pūwero mata). Heoi, mā te tīmata ki te rauemi iti-pūwero ka whakaitihia te hiahia mō aua maimoatanga me te mōrearea o ngā raruraru mahi e pā ana ki ngā pūwero.
Ngā Huihuinga Pei Hau Granite: Ngā Whakaaro Hoahoa
He maha ngā whakaaro hangarau mō tētahi atamira kawe hau katoa i runga i te karāhe, i tua atu i te mata aratohu tonu:
Hoahoa Utaina-mua
Me utaina mua ngā peera hau — arā, me ātete te kaha whakaora i tētahi āhua o te kawe ki te hiki ake i te mata ārahi. Ki te kore he utaina mua, ka rere noa te kawe i te mata i raro i tētahi whakakorikori ki runga. Ka tutuki te utaina mua mā tētahi o ēnei tikanga e toru:
Ka whakamahia e ngā whāriki hau e anga ke ana tētahi mata whāriki hau tuarua i te taha ke o tētahi ara ārahi, o tētahi mata papatahi rānei, ka hangaia he kaha pēhanga e anga ke ana e aukati ana i te kawe ki te aratohu, me te pupuri tonu i te wehenga kiriata hau i ngā taha e rua. Koinei te whirihoranga tino noa mō ngā wāhanga raina tika.
Ka whakamahia e ngā peera kua utaina mua he rohe korehau pokapū i roto i te mata o te peera, e karapotia ana e te rohe porowhita pēhanga. Ko te kaha kupenga ko te rerekētanga i waenga i te kaha hiki o te rohe pēhanga me te kukume o te rohe korehau, ka hua ake he kawenga kupenga ki te mata aratohu.
Ka whakamahia e te utaina mua o te aukume te kaha kukume i waenga i ngā aukume tuturu i roto i te waka me te arataki aukume hei kukume i te waka ki te mata. Ko tēnei huarahi me whakauru ngā huānga maitai, rino rānei ki te arataki karāhe, ka uaua ake te hoahoa engari ka taea te whakaputa i ngā huihuinga whāriki tino kiato.
Te Tukunga me te Tātari Hau
Ko ngā wāhanga kawe hau e hiahia ana kia tukuna tonutia he hau pēhi ma, maroke, kore-matūriki i te pēhanga kua whakaritea - ko te tikanga 0.4–0.6 MPa. Ko te poke o te tuku hau ki ngā aerosol hinu, te mamaoa wai, ngā matūriki totoka rānei tētahi o ngā tino take o te rahunga o te kawe hau. Ka pania ngā mata o te kawe e te poke hinu, ka whakarerekē i ō rātou āhua me te mākū; ka hangaia e te hauhautanga wai ngā rerekētanga pēhanga; ka taea e ngā matūriki totoka te whakakī i te āputa kawe me te patu i te mata o te waka me te mata arataki karāhe.
I roto i ngā taiao hanga haurua-haurua, ko te kounga o te tuku hau e whakahaeretia pai ana e ngā paerewa o ngā whare. I roto i ētahi atu taiao ahumahi, me āta whakarite kia tika te tātari me te whakamaroke i te tuku hau ki te atamira.
Ngā Pānga Wera ki te Kiriata Hau
Ka rerekē te matotoru o te hau i te pāmahana — tata ki te 2% ia nekehanga Celsius i te pāmahana rūma. Ka rerekē te pakari o te whāriki me te kaha hiki i te pāmahana mēnā ka rerekē te huringa pāmahana nui i roto i te tuku hau (mai i te rūma compressor ki te rūma ma e whakahaerehia ana te pāmahana, hei tauira). I roto i ngā tono tino tika, me whakahaere te pāmahana tuku hau me te pēhanga.
Ka whakaputahia e te āputa whāngai he iti noa te wera engari kāore i te kore mā te kutikuti matotoru o te kiriata hau. Mō ngā wāhanga tere-rahi, me whai whakaaro ki tēnei pūtake wera i roto i te tauira wera o te pūnaha hei karo i ngā pikinga pāmahana ohorere i roto i te karāhe, i te hanganga kawe rānei.
Te Ine me te Manatoko i te Mahi o te Wāhanga Āhuarangi
I muri i te huihuinga, me whakaahua te āhua o te atamira hau i runga i te karāhe hei whakamana i te tutuki i ana whakaritenga mahi. Ko ngā tawhā matua hei ine ko:
Te āheinga ki te tukurua i te tūnga — te ine mā te whakahau i te atamira ki tētahi raupapa o ngā tūnga ūnga me te tuhi i ngā tūnga tuturu mā te whakamahi i tētahi encoder raina taumira teitei, i tētahi interferometer laser rānei. Ka whakamātauhia te āheinga ki te tukurua rua-aronga (te whakatata mai i ngā taha e rua) mō te hysteresis.
Te tika o te haere — ka inehia mā te whakairi i tētahi taha tika tika (he maha ngā wā, he tohutoro karāhe tika) ki te taha o te ara haere, me te whakamahi i tētahi ine hiko hei ine i te peka o te kawe mai i tētahi rārangi tika i a ia e whakawhiti ana i tōna awhe katoa.
Ngā hapa koki (pitch, roll, yaw) — inehia mā te whakamahi i ngā autocollimators, i ngā taumata hiko rānei e mau ana ki runga i te kāreti, e kite ana i ngā huringa koki iti o te aronga o te kāreti i a ia e neke ana.
Te kai hau me te pakari o te peera — inehia mā te whakamahi i ngā kawenga e mōhiotia ana ki te kawe me te ine i te huringa āputa e puta mai ana (mai i te pānui o te encoder), kia taea ai te tatau i te pakari o te peera (te kaha mō ia nekehanga).
Mā ēnei inenga, e whakamahia ana ngā taputapu he tika te whakataunga me te whakatikatika ka taea te whai, ka whakaratohia te tūāpapa mahi e taea ai te pupuri me te whakamana anō i te atamira puta noa i tōna roanga mahi.
Ngā tono e tika ana mō ngā wāhanga e mau ana i te hau karāhe
Ka puta te huinga o te nekehanga o te hau me ngā mata arataki karāhe i ngā wāhi katoa e hiahiatia ana e te ahupūngao o te tono ō rāua āhuatanga whakakotahi:
Te tirotiro i te anga whakarewa me te tuhi kohatu — Kua kōrerohia whānuitia kētia; te tono paearu i ārahi i te whanaketanga o te hangarau ki tōna āhua o nāianei.
Keri PCB tere-teitei — Ko ngā mīhini keri maha-poro e tika ana kia whakanohohia ngā mata keri maha ki runga i te papa PCB i te wā kotahi, ka whakamahi i ngā turanga karāhe me ngā reti whakawhiti-hau hei whakatutuki i te huinga o te tere, te tika, me te pumau roa e hiahiatia ana.
Ine āhua whatu me te tirotiro mata — Me matawai e ngā taputapu e ine ana i te āhua o te mata i te taumira iti-nanomita tā rātou ine ine ki runga i te mata o te wāhanga me te nekehanga tino maeneene, iti-wiri. Mā ngā whāriki hau i runga i ngā mata arataki karāhe ka whakarato i te kounga nekehanga e hiahiatia ana.
Ko te miihini taiaho tino tika — ko ngā pūnaha taiaho femtosecond me picosecond e whakamahia ana mō te tango rauemi tino tika — i roto i ngā tono mai i te ophthalmology ki te microelectronics ki ngā wāhanga rererangi — me whai wāhi ki ngā wāhanga whakanoho me te tika taumata nanometer me te nekehanga maeneene, kore-toia kia tutuki ai te kounga tango e hiahiatia ana.
Whakatikatika tauine rārangi — Me neke e ngā pūnaha whakatikatika mō ngā waehere rārangi tika me ngā pūnaha ine whakawhiti laser tētahi taonga tohutoro me te kounga nekehanga pai kia kore ai te nekehanga e whakawhāiti i te tika o te whakatikatika. Ko ngā wāhanga kawe hau i runga i ngā mata aratohu granite tika te whiringa paerewa mō ngā pūnaha whakatikatika tino uaua.
Whakamutunga: Te Kiriata Ātea me te Kōhatu
Ko te hangarau whāriki hau me te karāhe tino tika, i roto i te tikanga hangarau pono, he mea hanga mō tētahi ki tētahi. Ko te ahupūngao o te mahi whāriki hau e whakatakoto ana i ngā whakaritenga pakari mō te taratara o te mata ārahi, te papatahi, me ngā āhuatanga rauemi — e hiahia ana kia tino tika te tūnga o te karāhe tino tika, ina hangaia, ina tukatukahia hoki ki ngā paerewa tika, kia tutuki ai. Ā, mā te whakakore i te waku me te kakahu pa, ka taea e ngā whāriki hau te whakamahi tonu i te mata o te karāhe tino tika i te tauine nanometer me te kore e pakaru.
Ko te hua he hangarau tūnga e kaha ana ki te whakatutuki i te kounga nekehanga — e inehia ana i roto i ngā nanometer — he mea whakamiharo pea ki ngā kaihangarau o te whakatupuranga o mua. Ko te mea kei runga i te kōhatu tawhito tēnei hangarau, ā-tinana, ā-whakaaro hoki, he mea whakakatakata rawa atu tēnei, he mea tino ātaahua tēnei o te hangarau tika o ēnei rā.
