Ina tīmata koe i tētahi kaupapa whakahihiri – ahakoa he hanga i tētahi mīhini CNC papamahi tika, kāore he hapa, he ringa karetao rānei e nekeneke maeneene ana – ko te whiriwhiri i ngā wāhanga matua mana tika te mea matua ki te angitu. I roto i ngā wāhanga whakahaere maha, kua noho ko ngā motuka stepper moroiti te mea tino pai mō ngā kaihanga, ngā miihini, me ngā kaihanga nā te mea he tika te whakahaere tuwhera-porowhita, he pai te pupuri i te taipana, me te utu iti.
Heoi, i te aroaro o te whānuitanga o ngā tauira me ngā tawhā uaua, me pēhea te whiriwhiri i te mōta hiko iti rawa e tika ana mō tō karetao, mō tō mīhini CNC rānei? Mēnā ka hē te kōwhiringa, ka iti ake te tika o te mahi, ka kore e ranea te mana, ka kore rānei e angitu te kaupapa. Ka noho tēnei aratohu hei pukapuka whiriwhiri whakamutunga māu, hei ārahi i a koe i ia taahiraa, i ia taahiraa, hei whakamārama i ngā āhuatanga matua katoa, hei whakatau whakaaro nui hoki.
Hipanga 1: Kia mārama ki ngā whakaritenga matua – te rerekētanga taketake i waenga i ngā karetao me te CNC
I mua i te tirotiro i tētahi tawhā, me whakamārama e koe ngā whakaritenga matua o tō horopaki tono mō te motuka.
Ngā kaupapa karetao (pērā i ngā ringa karetao, ngā karetao pūkoro):
Ngā whakaritenga matua: te urupare hihiri, te taumaha, te rahi, me te whai huatanga. Me mutu pinepine te tīmatanga, te tere rerekē, me te huri i te ahunga mō ngā hononga o ngā karetao, ā, ka pā tika te taumaha o te motuka ki te kawenga whānui me te whakapaunga hiko.
Ngā tohu matua: Kia aro nui atu ki te ānau tere taipana (ina koa ko te taipana tere waenga ki te tere teitei) me te ōwehenga mana ki te taumaha.
Ngā taputapu mīhini CNC (pērā i ngā mīhini whakairo tuaka-3, ngā mīhini tapahi taiaho):
Ngā whakaritenga matua: te pana, te maeneene, te pupuri i te taipana, me te tika. Me wikitoria e ngā taputapu mīhini CNC te ātete nui i te wā e tapahi ana, e whakairo ana rānei, me pupuri te nekehanga maeneene kia kore ai e wiri, me te whakanoho tika.
Ngā tohu matua: Kia aro nui ki te pupuri i te taipana i ngā tere iti, te taumira takahanga moroiti hei whakaiti i te wiri, me te pakari o te motuka.
Ko te mārama ki tēnei rerekētanga taketake te tūāpapa mō ngā whakataunga kōwhiringa katoa e whai ake nei.
Hipanga 2: Te Whakamārama i ngā Tawhā Matua e Rima o ngā Mōta Stepper Iti
Anei ngā tawhā matua e rima me aro atu koe ki roto i te pukapuka raraunga.
1. Te rahi me te taipana – te tūāpapa o te kaha
Rahi (tau turanga mīhini): e whakaatuhia ana i roto i ngā mirimita (pērā i te NEMA 11, 17, 23). Ko te paerewa NEMA e tautuhi ana i ngā ine tāutanga o ngā motuka, ehara i te mea ko tā rātou mahi. Ko te NEMA 17 te rahi rongonui mō ngā karetao papamahi me te CNC, e tutuki ai he taurite pai i waenga i te rahi me te taipana. Ko te NEMA 11/14 iti ake e pai ana mō ngā hononga karetao kawenga māmā; ko te NEMA 23 nui ake e pai ana mō ngā taputapu mīhini CNC nui.
Kia mau tonu te taipana: Ko te waeine ko N · cm, Oz · in rānei. Koinei te taipana mōrahi ka taea e te motuka te whakaputa ina whakakahangia engari kāore e hurihuri. Koinei te tohu tino nui mō te ine i te kaha o te motuka. Mō ngā taputapu mīhini CNC, me nui te taipana pupuri hei ātete i ngā kaha tapahi; mō ngā karetao, me tatau te taipana mōrahi e hiahiatia ana mō ngā hononga.
Me pēhea te whakatau i te taipana e hiahiatia ana?
Mō ngā mīhini CNC, ko te ture whānui ko te hiahia kia puta he taipana e taea ai te whakarato i te iti rawa 20-30N (tata ki te 2-3 kirokaramu) te pana axial. Me huri tēnei mā te arataki me te whai huatanga o te tīwiri. Mō ngā karetao, me whai tataunga hihiri uaua i runga i te roa o te ringa, te taumaha kawenga, me te whakaterenga. Kia mahara kia waiho he tawhiti taipana o te 30% -50% hei whakatau i ngā āhuatanga kāore i te tino mārama pēnei i te waku me te kore e taea te nekeneke.
2.Ko te koki me te tika o te takahanga - te wairua o te takahanga
Koki takahanga: pērā i te 1.8°, 0.9° rānei. Ka huri te motuka 1.8° i ia 200 takahanga, ko te motuka 0.9° ia e hiahia ana kia 400 takahanga. Ko te iti o te koki takahanga, ko te teitei ake o te tika o te motuka. He maeneene ake te motuka 0.9° i te nuinga o te wā ina oma i ngā tere iti.
3. Iahiko me te Ngaohiko – Te Whakataurite i ngā Atekōkiri
Iahiko ā-wāhanga: Ko te waeine ko Ampere (A). Koinei te iahiko whakatauranga mōrahi ka taea e ia takai ā-wāhanga o te motuka te tu atu. Mā tēnei tawhā ka whakatau tika ko tēhea puku me whiriwhiri e koe. Me ōrite te kaha o te iahiko putanga o te taraiwa ki te motuka.
Ngaohiko: Ko te tikanga ka whakatauhia ngā motuka mō ō rātou ngaohiko kua whakatauhia, engari ko te ngaohiko whakahaere tuturu ka nui ake i tēnei (ka whakatauhia e te taraiwa). Mā te ngaohiko teitei ake ka pai ake te mahi tere-tiketike o te motuka.
4. Te hiko whakaawe me te mahi tere-teitei – ngā āhuatanga matua e ngāwari ana te wareware
He mea nui te hiko whakapūmau i te taipana tere-teitei o te motuka. Ka taea e ngā motuka hiko iti te whakatū tere ake i te iahiko, ka hua ake he mahi pai ake i ngā tere teitei. Mena me huri tere ngā hononga o tō karetao, ki te hiahia rānei tō mīhini CNC ki te whakanui ake i te tere whāngai, me whiriwhiri e koe ngā tauira he iti te hiko whakapūmau.
5. Momo toki me te tikanga raina puta – ngā taipitopito o te hononga ā-mīhini
Ngā momo pou: tuaka whatu, pou kotahi papatahi, pou takirua papatahi, pou taputapu. Ko te tapahi momo-D (pou kotahi papatahi) te mea tino noa, ā, ka taea te ārai i te paheke o te hononga.
Tikanga putanga: putanga tika, mono-mai rānei. He watea te tikanga mono-mai (pērā i te pane rererangi 4-pine, 6-pine rānei) mō te tāutanga me te tiaki, ā, he kōwhiringa ngaio ake.
Hipanga 3: He hoa tino nui – me pēhea te whiriwhiri i tētahi taraiwa mōtini stepper
Kāore e taea e te mōtini tonu te mahi, me hono atu ki tētahi taraiwa mōtini takahuri. Ko te kounga o te taraiwa te mea e whakatau tika ana i te mahi whakamutunga o te pūnaha.
Hipanga-iti: Wehewehea te taahiraa katoa kia maha ngā taahiraa moroiti (pēnei i te 16, 32, 256 taahiraa moroiti). Ko te mahi matua o te taahiraa moroiti ko te whakangawari i te nekehanga o te motuka, me te whakaiti i te wiri me te haruru, he mea nui tēnei mō te kounga o te mata o ngā taputapu mīhini CNC.
Mana whakahaere o nāianei: He mahi haurua-aunoa ā-ringa ā ngā taraiwa tino pai. Ka whakaitihia aunoatia te au ina tū tonu te motuka, ka whakaitihia te whakaputa wera me te whakapaunga pūngao.
Ngā maramara/kōwae taraiwa noa:
Taumata whakaurunga: A4988- He iti te utu, he pai mō ngā kaupapa karetao māmā.
Kōwhiringa Matua: TMC2208/TMC2209- Tautoko ana i te taraiwa puku (aratau StealthShop), oma tino puku, he kōwhiringa pai mō ngā taputapu mīhini CNC, ā, e whakarato ana i ngā mahi whakahaere matatau ake.
Te mahi teitei: DRV8825/TB6600- e tautoko ana i te au me te ngaohiko teitei ake, e tika ana mō ngā tono e hiahia ana kia nui ake te taipana.
Kia maumahara: ka taea e te taraiwa pai te whakanui ake i te pūmanawa o te mōtini.
Hipanga 4: Te Tukanga Kōwhiri Whaihua me ngā Whakaaro Hē Noa
Tikanga whiriwhiri e whā ngā taahiraa:
Tautuhia te kawenga: Tautuhia mārama te taumaha mōrahi, te whakaterenga e hiahiatia ana, me te tere e hiahiatia ana e tō mīhini hei neke.
Tātaihia te taipana: Whakamahia he tātaitai taipana ipurangi, he tātai ā-ringa rānei hei whakatau tata i te taipana e hiahiatia ana.
Te kōwhiringa tuatahi o ngā motuka: Tīpakohia kia 2-3 ngā tauira kaitono i runga i ngā whakaritenga taipana me te rahi, ka whakatairite i ngā ānau tere taipana o aua tauira.
Kaitaraiwa ōrite: Tīpakohia te waeine taraiwa me te pūhiko hiko e tika ana i runga i te iahiko ā-wāhanga o te motuka me ngā mahi e hiahiatia ana (pēnei i te wahangu, te wehewehenga teitei).
Ngā Whakaaro Hē Noa (Aratohu mō te Karo i ngā Rua):
Whakaaro hē 1: Ko te nui ake o te taipana, ko te pai ake. Ko te taipana nui rawa he nui ake ngā motuka, he taumaha ake, he nui ake hoki te kaha e pau ana, he mea tino kino ki ngā hononga karetao.
Whakaaro Hē 2:Arotahi noa ki te pupuri i te taipana, kaua e aro ki te taipana tere nui. He nui te taipana o te motuka i ngā tere iti, engari i te piki haere o te tere, ka heke te taipana. Kia mahara ki te tirotiro i te tūtohi o te pihi tere taipana.
Whakaaro hē 3: Kāore i te rawaka te pūtake hiko. Ko te pūtake hiko te pūtake hiko o te pūnaha. Kāore e taea e te pūtake hiko ngoikore te taraiwa i te motuka ki te mahi i tōna pūmanawa katoa. Me rite te ngaohiko o te pūtake hiko ki waenganui o te ngaohiko whakatauranga o te taraiwa, ā, me nui ake te kaha o te iahiko i te 60% o te tapeke o ngā iahiko ā-wāhanga motuka katoa.
Hipanga 5: Ngā Whakaaro Matatau – Āhea tātou me Whakaaroaro ai ki ngā Pūnaha Porowhita Kati?
Ko ngā mōta takahuri tuku iho he mea whakahaere i te porowhita tuwhera, ā, ki te nui rawa te kawenga, ā, ka "ngaro te takahanga" o te mōta, kāore e taea e te kaiwhakahaere te mōhio. He hapa nui tēnei mō ngā tono e hiahia ana kia 100% te pono, pērā i te miihini CNC arumoni.
Ka whakauruhia e te motuka hiko-katia he encoder ki te pito o muri o te motuka, ka taea te aroturuki i te tūranga i te wā tūturu me te whakatika i ngā hapa. Ka whakakotahi i ngā painga o te taipana teitei mō ngā motuka hiko me te pono mō ngā motuka servo. Mena ko tō kaupapa:
Kāore e whakaaetia te mōrearea o te peka ke.
He mea tika kia whakamahia katoatia te mahi mōrahi o te mōtini (ka taea e te porowhita kati te whakarato i ngā tere teitei ake).
Ka whakamahia mō ngā hua arumoni.
Nō reira, he pai te haumi ki tētahi pūnaha stepper porowhita-katia.
Whakamutunga
Ko te whiriwhiri i te mōta hiko iti e tika ana mō tō karetao, mō tō mīhini CNC rānei, he mahi hangarau pūnaha e hiahia ana kia whai whakaaro whānuitia ki ngā āhuatanga miihini, hiko, me te whakahaere. Kāore he mōta 'pai', ko te mōta 'tino tika' anake.
Hei whakarāpopoto i ngā kaupapa matua, mai i te horopaki tono, ka whakatairangahia e ngā karetao te mahi hihiri me te taumaha, ko ngā taputapu mīhini CNC ia ka whakatairangahia e te taipana me te pumau. Kia mau ki ngā tawhā matua o te taipana, te iahiko, me te ine hiko, ā, me whakarato ki tētahi taraiwa pai me te puna hiko e ranea ana. Mā te aratohu o tēnei tuhinga, ko taku tumanako ka taea e koe te whiriwhiri māia mō tō kaupapa nui e whai ake nei, me te whakarite kia tika, kia kaha, kia pono hoki te oma o āu mahi auaha.
