I roto i ngā taputapu whakahaere tau CNC, ahakoa ko ngā āhuatanga ā-tinana o te karāhe te pūtake mō te tukatuka tino tika, tera pea he pānga maha-ahu o ōna ngoikoretanga ki te tika o te tukatuka, e whakaatuhia ana penei:
1. Ngā hapa o te mata i te tukatuka i puta mai i te pakarukaru o te rauemi
Nā te āhua pakarukaru o te karāneti (he kaha pēhi teitei engari he iti te kaha piko, ko te kaha piko he 1/10 ki te 1/20 noa iho o te kaha pēhi) ka ngāwari ki te pāngia e ngā raruraru pēnei i te ngatata o te taha me ngā kapiti moroiti o te mata i te wā e tukatukahia ana.
Ka pāngia te whakawhiti tika e ngā hapa moroiti: I te wā e mahi ana i te huri, i te mira rānei, ka taea e ngā kapiti iti i ngā wāhi pa o te taputapu te hanga i ngā mata koretake, ka puta ai ngā hapa tika o ngā wāhanga matua pēnei i ngā ara ārahi me ngā tēpu mahi (hei tauira, ka heke te papatahi mai i te ±1μm/m ki te ±3~5μm/m). Ka tukuna tika atu ēnei hapa moroiti ki ngā wāhanga kua tukatukahia, inā koa i roto i ngā āhuatanga tukatuka pēnei i ngā wāhanga whatu tika me ngā kawe angiangi haurua-ira, ka piki ake pea te taratara o te mata o te mea mahi (ka piki ake te uara Ra mai i te 0.1μm ki te neke atu i te 0.5μm), ka pā ki te mahi whatu, ki te mahi rānei o te taputapu.
Te mōrearea o te pakaru ohorere i roto i te tukatuka hihiri: I roto i ngā āhuatanga tapahi tere-teitei (pēnei i te tere o te porowhita > 15,000 r/min) te tere whāngai rānei > 20m/min, ka pakaru pea ngā wāhanga o te karāhe nā te kaha pānga ohorere. Hei tauira, ina huri tere te ahunga o te takirua ara ārahi, ka taea e te pakaru o te taha te mea ka peka ke te ara nekehanga mai i te ara ariā, ka hua ake he hekenga ohorere o te tika o te tūnga (ka piki ake te hapa tūnga mai i te ±2μm ki te neke atu i te ±10μm), ā, ka arahi atu ki te tukinga me te pakaru o te taputapu.
Tuarua, ko te ngaronga o te tika hihiri i puta mai i te taupatupatu i waenga i te taumaha me te pakari
Ka taea e te āhuatanga matotoru o te karāhe (me te matotoru o te 2.6 ki te 3.0g/cm³) te pehi i te wiri, engari ka puta mai hoki ēnei raruraru:
Ka puta te whakaroa o te urupare servo nā te kaha korekore: Ko te kaha korekore i hangaia e ngā moenga karāhe taumaha (pērā i ngā moenga mīhini gantry nui e taea te taumaha i ngā tekau tāne) i te wā whakaterenga me te whakaroa ka akiaki i te motuka servo ki te whakaputa i te taipana nui ake, ka hua ake he pikinga o te hapa aroturuki i te koropiko tūranga. Hei tauira, i roto i ngā pūnaha tere-teitei e peia ana e ngā motuka raina, mō ia pikinga 10% o te taumaha, ka heke pea te tika o te tūranga mā te 5% ki te 8%. Ina koa i roto i ngā horopaki tukatuka nano, ka taea e tēnei whakaroa te arahi ki ngā hapa tukatuka āhua (pērā i te pikinga o te hapa porowhita mai i te 50nm ki te 200nm i te wā o te whakapūtanga porowhita).
Ka iti te auau o te wiri i te kore e ranea te pakari: Ahakoa he nui te whakamātao ā-roto o te karāhe, he iti ake tōna kaha ngāwari (tata ki te 60 ki te 120GPa) i tērā o te rino maka. Ina tukuna ki ngā kawenga tauutuutu (pērā i te rerekētanga o te kaha tapahi i te wā e tukatuka ana i te hononga maha-tuaka), ka puta pea te kohikohinga o te ahua moroiti. Hei tauira, i roto i te wāhanga pane hurihuri o te pokapū miihini e rima-tuaka, ka taea e te ahua ngāwari ngāwari o te turanga karāhe te mea ka neke te tika o te tūnga koki o te tuaka hurihuri (pērā i te hapa taupū e horapa ana mai i te ±5" ki te ±15"), ka pā ki te tika o te miihini o ngā mata piko matatini.
III. Ngā Here o te Pūmautanga Wera me te Tairongo ki te Taiao
Ahakoa he iti iho te tauwehenga whānui wera o te karāhe (tata ki te 5 ki te 9×10⁻⁶/℃) i tērā o te rino maka, tera pea ka puta he hapa i roto i te tukatuka tika:
Ka puta te rerekētanga o te hanganga nā ngā pikinga pāmahana: Ina mahi tonu te taputapu mō te wā roa, ka taea e ngā pūtake wera pēnei i te motuka matua me te pūnaha whakahinuhinu arataki te whakaputa i ngā pikinga pāmahana i roto i ngā wāhanga karāhe. Hei tauira, ina 2℃ te rerekētanga pāmahana i waenga i ngā mata o runga me raro o te tēpu mahi, ka puta pea he rerekētanga waenga-pūpū, waenga-kōpiko rānei (ka taea e te piko te eke ki te 10 ki te 20μm), ka arahi ki te korenga o te papatahi o te piri o te mea mahi, ā, ka pā ki te tika o te whakarara o te mira, te huri rānei (pēnei i te manawanui matotoru o ngā wāhanga pereti papatahi neke atu i te ±5μm ki te ±20μm).
Ka paku whānui te haumākū o te taiao: Ahakoa he iti te tere mimiti wai o te karāhe (0.1% ki te 0.5%), ina whakamahia mō te wā roa i roto i te taiao haumākū nui, ka taea e te iti o te mimiti wai te arahi ki te whānui o te whatunga, ka puta ai he huringa ki te āputa o te takirua arataki. Hei tauira, ina piki te haumākū mai i te 40% RH ki te 70% RH, ka piki pea te whānuitanga raina o te arataki karāhe mā te 0.005 ki te 0.01mm/m, ka heke te maeneene o te nekehanga o te arataki reti me te puta o te āhuatanga "ngoki", ka pā ki te tika o te whāngai taumata-micron.
IV. Ngā Pānga Whakaemi o ngā Hapa Tukatuka me te Huihuinga
He nui te uauatanga o te tukatuka i te karāhe (me whakamahi taputapu taimana motuhake, ā, ko te pai o te tukatuka he 1/3 ki te 1/2 noa iho o te pai o ngā rauemi whakarewa), ka ngaro pea te tika o te tukanga huihuinga:
Te tuku hapa tukatuka o ngā mata taunga: Mena he rerekētanga tukatuka (pēnei i te papatahi > 5μm, te hapa mokowā kōhao > 10μm) i roto i ngā wāhanga matua pēnei i te mata tāutanga o te arataki arataki me ngā kōhao tautoko tīwiri mata, ka puta he whakapōturitanga o te arataki arataki raina i muri i te tāutanga, he kore taurite te utaina o te tīwiri pōro, ā, i te mutunga ka heke te tika o te nekehanga. Hei tauira, i te wā e tukatukahia ana te hononga tuaka-toru, ko te hapa poutū i puta mai i te whakapōturitanga o te arataki arataki ka whakawhānui ake i te hapa roa whakarara o te poraka mai i te ±10μm ki te ±50μm.
Te āputa o te hanganga honohono: He maha ngā wā ka whakamahia e ngā wāhanga karāhe o ngā taputapu nui ngā tikanga honohono (pēnei i te honohono moenga maha-wāhanga). Mena he hapa koki iti (> 10"), he taratara rānei o te mata > Ra0.8μm i runga i te mata honohono, ka puta pea te kukū ahotea, ngā āputa rānei i muri i te huihuinga. I raro i te kawenga mō te wā roa, ka arahi pea ki te whakangāwari o te hanganga me te puta he paheketanga o te tika (pēnei i te hekenga o te 2 ki te 5μm i roto i te tika o te tūnga i ia tau).
Whakarāpopototanga me ngā whakahihiko mō te aro atu ki ngā āhuatanga o te ao
He pānga huna, he pānga whakaemi, he pānga tairongo hoki o te karāneti ki te tika o ngā taputapu CNC, ā, me aro nui ki te taiao mā roto i ngā huarahi pēnei i te whakarerekētanga rauemi (pēnei i te whakakī kapia hei whakarei ake i te pakari), te arotautanga hanganga (pēnei i ngā anga whakakotahi karāneti-whakarewa), te hangarau whakahaere wera (pēnei i te whakamatao wai i roto i ngā awa iti), me te utunga hihiri (pēnei i te whakatikatika wā-tūturu me te ine whakawhiti laser). I roto i te mara o te tukatuka tika nanoscale, he mea nui ake te whakahaere i te mana mekameka katoa mai i te kōwhiringa rauemi, te hangarau tukatuka ki te pūnaha mīhini katoa kia tino whakamahia ai ngā painga mahi o te karāneti me te karo i ōna hapa ā-roto.
