I roto i te whai tonu i te hiranga o te hanga, ko te pumau o te turanga o te mīhini CNC te mea nui rawa atu. I te mea ka piki ake te tere o te porowhita i te 30,000 RPM, ā, ka heke ngā manawanui ki te taumata iti-micron, ko te rauemi hanganga o te moenga mīhini—e kiia ana ko te "turanga"—ka noho hei mea whakatau i waenga i te whakaotinga mata kounga teitei me te wāhanga kua para. Mō ngā tekau tau, kua tautohetohe te umanga mō ngā painga o ngā rauemi turanga rerekē, me te rino maka tuku iho e ngaro ana i te whenua ki ngā kōwhiringa pai e rua: Ko te Granite Taiao me te Mineral Casting (e mōhiotia ana ko te raima polymer, ko te granite horihori rānei).
Ahakoa he nui ngā painga o ngā rauemi e rua i te konganuku, me mārama hōhonu ki ō rāua āhuatanga ā-tinana mā te whiriwhiri i waenga i a rāua, inā koa mō te whakaiti i te wiri. Kei roto i tēnei tuhinga he tātaritanga hangarau mō te rerekētanga o te Maka Kohuke me te Granite Taiao i roto i tō rāua kaha ki te mimiti i te pūngao, te ātete i te whakarerekētanga wera, me te pupuri i te pumau āhuahanga i roto i ngā taiao miihini tere-rahi.
Te Ahupūngao o te Wiri: He aha te Hiranga o te Whakaiti
Hei mārama ki te whakataurite, me tautuhi tuatahi tātou i te raruraru. I roto i te miihini CNC, ko te wiri te hoariri o te tika. Ka puta ngā wiri i te nekehanga tere o ngā toki, te hurihanga o te miro, me ngā kaha tapahi e taunekeneke ana ki te mea mahi. Ki te kore ēnei wiri e marara, ka hua ake he "haruru" - he ngaru e kitea ana i runga i te mata o te mea mahi, ka tere ake te mau o te taputapu, me te kino pea ki ngā aratohu raina me ngā peera o te mīhini.
Ko te kaha o tētahi rauemi ki te mimiti i tēnei pūngao nekeneke me te huri hei iti noa te wera ka inehia e tōna tauwehenga whakamākū (te tauwehenga ngaronga rānei). Koinei te wāhi e tino rerekē ai te Maka Kohuke me te Granite Taiao i ngā konganuku, ā, i a rātou anō hoki.
Te Karāhe Taiao: Te Paerewa Matawhenua
Kua roa te karāhe tūturu e noho ana hei paerewa koura mō te ine ine me ngā turanga mīhini tino tika, inā koa i roto i ngā Mīhini Ine Taurite (CMM) me te huri tino tika. Ko tōna rongonui i ahu mai i tōna hītori whenua. I hangaia i roto i ngā miriona tau i raro i te wera me te pēhanga nui, he rauemi pumau taiao te karāhe, kāore he ahotea o roto.
He tino mīharo te kaha o te karāhe tūturu ki te whakamākū. He hanganga matotoru, he tioata tōna e tino pakari ana, ā, e 5 ki te 10 ngā wā e nui ake ana tōna kaha ki te whakamākū i tō te rino maka hina. Ina pā te ngaru wiri ki te turanga karāhe, ka āwhina te hanganga tioata honohono matatini ki te tere whakamāhorahora i te kaha.
Hei tāpiritanga, he koretake te karāneti i roto i ngā matū, ā, kāore he aukume. Kāore e waikura, ā, he ātete ki ngā pānga waikura o ngā wai whakamatao me ngā hinu. Ko tōna tauwehenga whānui wera he haurua pea i te maitai, ko te tikanga he iti ake te ngāwari ki ngā huringa āhuahanga i puta mai i ngā huringa pāmahana taiao. Heoi, nā te mea he rauemi taiao, he anisotropic - ka rerekē pea ōna āhuatanga i runga i te ahunga o te kakano - ahakoa ko te "karaneti pango" kounga teitei (he maha ngā wā he diabase, he basalt rānei) ka tīpakohia mō tōna ōritetanga.
Te Maka Kohuke: Te Hikoi Hangarau
Ko te whakarewanga kohuke, e mōhiotia whānuitia ana ko te raima polymer, ko te karāneti horihori rānei, te tihi o ngā rauemi hanganga hangarau. He ranunga hiato tēnei e titoa ana i te 90-95% o ngā mea taiao (pērā i te quartz, ngā maramara karāneti, te basalt rānei) e herea ana ki te 5-10% o te hanganga kapia polymer, ko te nuinga he epoxy.
I hangaia tēnei rauemi hei aro atu ki ngā herenga o ngā konganuku, ā, i ētahi āhuatanga, o te kōhatu tūturu. Ko te tukanga hanga ko te ringihia o te ranunga ki roto i tētahi pokepokea i te pāmahana rūma, e āhei ai te hanga i ngā hanganga uaua, tuwhera me ngā āhuatanga whakauru pērā i ngā awa whakamatao me ngā paipa taura.
Ko te mahi whakamākū o te Maka Kohuke tōna āhuatanga matua. Nā te āhua viscoelastic o te here kapia epoxy, ka whakaatuhia e te Maka Kohuke he kaha whakamākū e 6 ki te 10 ngā wā nui ake i te rino maka, ā, he mea nui, he 2 ki te 4 ngā wā nui ake i te karāhe tūturu. Ka mahi te matrix polymer hei ātete ru i runga i te taumata moroiti, e "kai" ana i te kaha wiri i mua i te horapa i roto i te hanganga mīhini.
Te Whakataetae Whakaiti: Te Maka Kohuke me te Karāhe Taiao
Ina whakaritea tika ngā mea e rua, ko te rerekētanga kei roto i te tikanga o te mararatanga o te pūngao.
Ka whakawhirinaki te Granite Taiao ki tōna waku ā-roto i waenga i ngā tioata kohuke. Ahakoa he tino whai hua, he rauemi pakari. I roto i ngā tono tere-teitei e tere ai te hanga o ngā auau harmonic, ka whakaratohia e te granite he tūāpapa tino pumau, engari ka taea tonu e ia te tuku i ētahi wiri auau-teitei i runga i te hanganga whenua motuhake o te kohatu.
I tetahi atu taha, ka whakamahia e te Maka Kohuke te hononga honohono i waenga i te konganuku mārō me te kapia ngohengohe. Ka hangaia e tēnei hanganga he porowhita hysteresis nui i te wā e utaina ana, e tangohia ana hoki, ā, ka pai ake te mimiti o te pūngao. E whakaatu ana ngā rangahau me ngā raraunga ahumahi ko te ōwehenga whakaiti o te Maka Kohuke ka taea te awhe mai i te 0.02 ki te 0.045, he nui ake te pai ake i te pito o raro o te whānuitanga o te karāhe. Nā tēnei ka tino whai hua te Maka Kohuke i roto i ngā mahi "ngāwari ki te haruru" pērā i te keri hohonu-poka, te mira tere-teitei o te titanium, ngā huarahi whakaoti rānei i te wā e tino nui ana te taratara o te mata.
I roto i ngā kupu mahi, ka tere ake te tau o te mīhini he turanga whakarewa kohuke i muri i te nekehanga tere i tērā he turanga karāhe, kia poto ake ai te wā huringa me te nui ake o te kaha whakaputa.
Te Pūmautanga o te Wera me te Pūmautanga Āhuahanga
Haunga te wiri, ko te whanonga wera tētahi atu rerekētanga nui.
He rongonui te karāhe taiao mō tōna ātete wera. He iti tōna kawe wera, arā, he roa te wā e wera ai, e whakamatao ai rānei. He pai tēnei "whakaroa" i roto i ngā taiao e rerekē ana te pāmahana, nā te mea ko te turanga mīhini te mea e totohu ana i te wera, e mau tonu ana tōna āhua ahakoa ka rerekē te pāmahana o te papa o te whare mahi. Heoi, he uaua te mīhini i te karāhe. Me mahi pūkenga me te wā te hanga i tētahi mata papatahi tino pai, ā, ko ngā āhuatanga whakauru (pēnei i ngā whakaurunga miro) he maha ngā wā me keri me te whakapiri, ka puta ai ngā ngoikoretanga.
He momo pumau wera rerekē tā te Mineral Casting. Nā te mea ka whakamaroketia i te pāmahana rūma, kāore he ahotea wera e toe ana. Kāore i rite ki te rino maka, ka taea te piko i te mea ka memeha haere ngā ahotea o roto i ngā tau maha o te whakamahinga, ka mau tonu te āhua āhuahanga o te Mineral Casting mō ake tonu atu. He tino iti te tauwehenga o te whānui wera, ā, ka taea te whakarite i te wā o te tukanga hanga kia rite ki te maitai, he mea pai tēnei ina whakairihia ngā arataki raina maitai ki runga i te turanga.
Heoi, he iti ake te kawe wera o te whakarewa kohuke i te karāhe. Ahakoa he pumau tēnei, ko te tikanga mēnā ka puta te werarotote turanga (hei tauira, mai i tētahi motuka e mau tika ana ki runga), kāore pea taua wera e tere memeha atu pērā i roto i te karāhe. Nō reira, ko ngā rautaki whakahaere wera, pērā i ngā awa whakamatao ā-roto (e ngāwari ana te maka ki roto i te Makanga Kohuke), he mea nui ake mō ngā turanga raima polymer.
Te Herekoretanga Hoahoa me ngā Pānga Hanga
Ka pāngia hoki te hoahoa o te mīhini e te kōwhiringa i waenga i ēnei rauemi.
He iti noa te rahi o ngā poraka i keria mō te karāhe taiao. He maha ngā wā ka hiahiatia kia honoa ngā kōhatu maha ki ngā turanga mīhini nui, ka puta he hononga ka pā ki te pakari me te whakamākū. Hei tāpiri, he pakarukaru te karāhe; ka taea e te pānga koi mai i tētahi taputapu, i tētahi mea mahi rānei e hinga ana te pakaru, te pakaru rānei o te turanga, ā, ka nui te utu mō ngā whakatikatika, te whakakapinga rānei.
He tino herekore te whakarewanga kohuke mō te hoahoa. Ka taea te whakarewa ki ngā āhua uaua, kotahi te āhua, me ngā matotoru pakitara rerekē. Mā tēnei ka taea e ngā kaihangarau te arotau i te ōwehenga pakari-ki-taumaha, ka hangaia he hanganga mama ake, engari he pakari ake i ō rātou hoa granite. Hei tāpiri, ka taea te whakarewa tika i ngā huānga mahi—pērā i ngā miro whakairi, ngā aho hau, tae noa ki ngā whakairinga tauine raina—ki roto i te rauemi, ka whakaiti i te wā huihuinga me te whakakore i ngā pūtake wiri pea i puta mai i ngā hononga pūmau.
Whakamutunga: Te Kōwhiri i te Tūāpapa Tika
He tino rerekē te whakarewatanga o te karāhe taiao me te whakarewanga kohuke i te rino maka tuku iho, e whakarato ana i te pumau e hiahiatia ana mō te hanga tino tika o ēnei rā.
Mena kei roto i tō tono te ine ine tino tika, ngā taiao rānei e aro nui ana ki te whakaroa wera, he kōwhiringa kaha tonu a Natural Granite nā tōna pumau ā-whenua me tōna hītori kua whakamātauhia i roto i ngā CMM.
