I roto i ngā taputapu whakahaere tau CNC, ahakoa kua noho te karāhe hei rauemi nui nā ōna āhuatanga ahurei, tera pea ka pāngia te mahi a ngā taputapu, te pai o te tukatuka me ngā utu tiaki e ōna ngoikoretanga ā-roto. Anei tētahi tātaritanga o ngā pānga motuhake i puta mai i ngā ngoikoretanga o te karāhehe mai i ngā āhuatanga maha:
Tuatahi, he tino pakarukaru te rauemi, ā, he ngāwari ki te whati me te kino
Te ngoikoretanga matua: He kōhatu tūturu te karāneti, ā, he mea pakarukaru, he ngoikore te pakari o te pānga (ko te uara pakari o te pānga he tata ki te 1-3J/cm², he iti iho i te 20-100J/cm² o ngā rauemi whakarewa).
Pānga ki ngā taputapu CNC:
Ngā mōrearea o te tāutanga me te kawe: I te wā e huihui ana, e whakahaeretia ana rānei ngā taputapu, ki te pāngia, ka taka rānei, ka ngawari te pakaru, te pakaru rānei o ngā kokonga o ngā wāhanga karāhe (pērā i ngā turanga me ngā ara ārahi), ka kore e tika te mahi. Hei tauira, ki te puta he pakaru huna i te papa karāhe o tētahi mīhini ine taunga-toru nā te kore e tika te whakahaere i te wā tāutanga, ka heke haere pea te papatahi i te whakamahinga roa, ka pā ki ngā hua ine.
Ngā tūponotanga huna i roto i te tukanga tukatuka: Ina tūpono ngā taputapu CNC ki te taumaha rawa (pēnei i te tukinga o te taputapu ki te mea mahi), ka pakaru pea ngā ara ārahi karāhe, ngā tēpu mahi rānei nā te kore e taea te tu atu i te kaha pānga ohorere, ka mutu ai te taputapu mō te tiaki, ā, ka puta pea he mekameka o ngā hapa tika.
Tuarua, ko te uauatanga nui o te tukatuka ka whakawhāiti i te hoahoa o ngā hanganga uaua.
Ngā ngoikoretanga matua: He pakeke rawa te karāneti (6-7 i te tauine Mohs), ā, me huri me te tukatuka mā ngā taputapu motuhake pēnei i ngā wira huri taimana, ka iti ake te pai o te tukatuka (he 1/5 ki te 1/3 noa iho te pai o te mira i tērā o ngā rauemi whakarewa), ā, he nui te utu mō te tukatuka i ngā mata piko uaua.
Pānga ki ngā taputapu CNC:
Ngā herenga hoahoa hanganga: Hei karo i ngā uauatanga tukatuka, he maha ngā wā ka hangaia ngā wāhanga karāhe ki ngā āhua ā-ira māmā (pērā i ngā pereti, ngā ara ārahi tapawhā), ā, ka uaua ki te whakatutuki i ngā kōhao o roto uaua, ngā pereti māmā kua whakapakeketia me ētahi atu hanganga ka taea te whakatutuki mā te whakarewa/tapahi me ngā rauemi whakarewa. Nā tēnei ka hua ake he nui rawa te taumaha o te turanga karāhe (10%-20% taumaha atu i te rino maka mō te rōrahi kotahi), ka piki ake pea te kawenga katoa o ngā taputapu, ā, ka pā ki te mahi urupare hihiri i te wā o te nekehanga tere-teitei.
Te utu tiaki me te whakakapinga nui: Ina pakaru, ina pakaru rānei ngā wāhanga o te karāhe, he uaua ki te whakatika mā roto i ngā tikanga pēnei i te whakarewa, te tapahi rānei. I te nuinga o te wā, me whakakapi te wāhanga katoa, ā, me huri anō ngā wāhanga hou, me whakatikatika kia tika, ka roa ake te wā kore mahi (tērā pea ka roa te whakakapinga kotahi mō te 2-3 wiki), ā, ka nui ake te utu tiaki.
Iii. Te koretake o ngā kakano taiao me ngā hapa ā-roto
Te ngoikoretanga matua: Hei kohuke tūturu, he kapiti ā-roto, he pūwero, he poke rānei o te kohuke te karāhe, ā, he rerekē rawa te ōritetanga o ngā rauemi o ngā uaua rerekē (ka eke te pikinga o te mātotoru ki te ±5%, te pikinga o te tauwehenga pīngore ±8%).
Pānga ki ngā taputapu CNC:
Te mōrearea o te pumau o te mahi: Mena ka pāngia te wāhi tukatuka o te wāhanga e ngā kapiti o roto, i te wā e whakamahia ana mō te wā roa, ka whānui pea ngā kapiti nā te taumahatanga, ka puta he rerekētanga ā-rohe, ā, ka pā ki te tika o ngā taputapu. Hei tauira, mena he pūaha hau huna kei roto i ngā ara ārahi karāhe o te mīhini huri CNC, ka hinga haere pea i raro i te wiri auau teitei, ka hua ake he hapa nui o te tika o ngā ara ārahi.
Ngā rerekētanga mahi puranga: Tērā pea ka pāngia ngā rauemi karāneti mai i ngā puranga rerekē e ngā rerekētanga o ngā tohu matua pērā i te tauwehenga o te whakawhānui wera me te mahi whakaiti i te wera nā te rerekētanga o te hanganga kohuke, e pā ana ki te ōritetanga o te whakaputa puranga e ngā taputapu. Mō ngā raina whakaputa aunoa e hiahia ana ki te taunekeneke o ngā taputapu maha, ka arahi pea ēnei rerekētanga ki te pikinga o te marara o te tika o te tukatuka.
Tuawhā, he taumaha, e pā ana ki te mahi hihiri o te taputapu
Te ngoikoretanga matua: He nui te mātotoru o te karāneti (2.6-3.0g/cm³), ā, ko tōna taumaha he tata ki te 1.2 ngā wā o te rino maka, ā, he 2.5 ngā wā o te konumohe koranu i raro i te rōrahi kotahi.
Pānga ki ngā taputapu CNC:
Te whakaroa o te urupare nekehanga: I roto i ngā pokapū mīhini tere-teitei, i ngā mīhini tuaka-rima rānei, ka whakanuia e te papatipu nui o te turanga karāhe te ātete kawenga o te motuka raina/tīwiri mata, ka hua ake he whakaroa urupare hihiri i te wā whakaterenga/whakapōturitanga (ka piki ake pea te wā tīmatanga-mutu mā te 5% ki te 10%), ka pā ki te whai huatanga o te tukatuka.
Te whakanui ake i te whakapaunga pūngao: Ko te taraiwa i ngā wāhanga karāhe taumaha me whai motuka servo kaha ake, ka piki ake te whakapaunga pūngao katoa o ngā taputapu (e whakaatu ana ngā inenga tuturu i raro i ngā āhuatanga mahi ōrite, ko te whakapaunga pūngao o ngā taputapu turanga karāhe he 8%-12% teitei ake i tō ngā taputapu rino maka). Ka piki ake ngā utu whakaputa mēnā ka whakamahia mō te wā roa.
E rima, he iti te kaha ki te ātete i te ru wera
Te ngoikoretanga matua: Ahakoa he iti te tauwehenga whānui o te karāhe, he ngoikore tōna kawe wera (ko te kawe wera o te 1.5-3.0W/(m · K) anake, tata ki te 1/10 o te kawe wera o te rino maka), ā, ka ngāwari te hurihanga ohorere o te pāmahana ā-rohe ki te whakaputa i te ahotea wera.
Pānga ki ngā taputapu CNC:
Te rerekētanga pāmahana i te wāhi tukatuka: Mena ka memeha haere te wai tapahi i tētahi wāhi o te tēpu mahi karāhe, ka puta he pikinga pāmahana (pēnei i te rerekētanga pāmahana o te 5-10℃) i waenganui i tēnei wāhi me te wāhi e karapoti ana, ka hua ake he rerekētanga pāmahana iti (ka taea e te nui o te rerekētanga te eke ki te 1-3μm), ka pā ki te ōritetanga tika o te tukatuka tika (pēnei i te huri taputapu taumata-micron).
Te mōrearea o te ngenge wera mō te wā roa: I roto i ngā taiao awheawhe e maha ana ngā tīmatanga me ngā whakaweto, ngā rerekētanga nui rānei o te pāmahana i waenga i te ao me te pō, ka puta pea ngā kapiti moroiti i ngā wāhanga o te karāhe nā te whānui me te whakahekenga wera tonu, ka ngoikore haere te pakari o te hanganga.
