①. He whakarāpopototanga o te tukatuka pepa whakarewa
Ko te tukatuka pepa whakarewa e kiia ana ko te tukatuka pepa whakarewa. Hei tauira, ko te whakamahinga motuhake o te auahi pereti, te peere rino, te kēne tāke hinu, te paipa hauhautanga, te pane rahi tuke, te wāhi māra awatea, te hāneanea, me ētahi atu, ko te tukanga matua ko te kutikuti, te piko i te taha o te whitiki, te piko, te whakarewa, te whakakī, me ētahi mōhiotanga āhuahanga. Ko ngā wāhanga pepa whakarewa he wāhanga pepa whakarewa, ka taea te tukatuka mā te tā, te piko, te totoro me ētahi atu tikanga. Ko te whakamāramatanga whānui ko te matotoru o ngā wāhanga kāore e rerekē i te wā e tukatukahia ana. E rite ana ki te maka, te hanga wāhanga, te miihini wāhanga, me ētahi atu. Ko te kōwhiringa o ngā rauemi tukatuka pepa whakarewa e whakamahia whānuitia ana i roto i ngā rauemi tukatuka pepa whakarewa ko te pepa hurihuri matao (SPCC), te pepa hurihuri wera (SHCC), te pepa whakapūmau (SECC, SGCC), te parahi (Cu) parahi, te parahi, te parahi beryllium, te pereti konumohe (6061, 6063, te konumohe mārō, me ētahi atu), te kōtaha konumohe, te kowiri tira (whakaata, mata tuhi, mata kohu), kia rite ki te mahi a ngā hua rerekē, Kōwhiri rauemi kia rerekē, me whakaaro whānuitia tōna whai huatanga me te utu mai i te hua.
Te tukatuka pepa whakarewa
1. Pereti SPCC hurihuri matao, e whakamahia ana mō te whakakikorua hiko me te tunu peita i ngā wāhanga, he iti te utu, he ngāwari ki te hanga, he matotoru rauemi ≤3.2mm.
2. Pereti huri wera SHCC, rauemi T≥3.0mm, me ngā wāhanga whakakikoruatia hiko, peita tunu, he iti te utu, engari he uaua ki te hanga, ko te nuinga he papatahi.
3. Rau piauau SECC, SGCC. Kua wehea te papa hiko SECC ki te rauemi N me te rauemi P. Kāore te rauemi N e whakamahia ana mō te maimoatanga mata, ā, he nui te utu, ko te rauemi P ia e whakamahia ana mō te rehu i ngā wāhanga.
4. Parahi; Ko te nuinga he rauemi mahi kawe, ko tōna mata he whakakikoruatia ki te nikara, he whakakikoruatia ki te kōroma, he kore rānei e hangaia he maimoatanga, he nui te utu.
5. Pereti konumohe; Te whakamahinga whānui o te chromate mata (J11-A), te whakahāngaitanga (whakahāngaitanga kawe, whakahāngaitanga matū), te utu nui, te whakakikorua hiriwa, te whakakikorua nikara.
6. Lu: xingcai; He whānuitia te whakamahinga o ngā rauemi me ngā wāhanga he uaua te hanganga wāhanga i roto i ngā pouaka whakauru, ā, he rite tonu te maimoatanga mata ki te pereti konumohe.
7. Kowiri tira; Ka whakamahia whānuitia, kāore he maimoatanga mata, he nui te utu.
②. Ngā mea e tika ana kia arohia mō te whanaketanga o te tukatuka pepa whakarewa:
1. Me kati te ara whanaketanga, ā, me watea hoki ki te penapena rauemi me te ngāwari o te tukatuka
2. Kōwhiringa whaitake o te āputa me te tikanga takai taha, T=2.0 i raro i te āputa 0.2, T=2-3 āputa 0.5, tikanga takai taha ma te whakamahi i te taha roa me te taha poto (momo panera tatau)
3. Whakaarohia ngā āhuatanga manawanui: ka tae te rerekētanga kino ki te mutunga, ka tae te rerekētanga pai ki te haurua; Rahi o te kōhao: ka tae te rerekētanga pai ki te mutunga, ka tae te rerekētanga kino ki te haurua.
③. Tukanga tukatuka whakarewa pepa
Whāngai: he maha ngā huarahi whāngai, ko ngā huarahi matua e whai ake nei
(1). Mīhini kutikuti: he mīhini kutikuti e whakamahi ana i ngā rauemi rīpene, he māmā noa iho ngā wāhanga, ko te nuinga mō te tukatuka i te hanga pokepokea ai, he iti te utu, he iti iho i te 0.2 te tika, engari kāore e taea te tukatuka i tētahi kōhao me te kore e tapahia te koki o te rauemi rīpene, poraka rānei.
(2). Pēhi patupatu: ko te whakamahinga o te pēhi patupatu i roto i te kotahi, neke atu rānei o ngā taahiraa i roto i ngā wāhanga pereti ka whakawhānuihia i muri i te patupatu o te wahi papatahi ka hanga i ngā momo āhua o ngā rauemi, ko ōna painga he poto te wā e pau ana, he pai te mahi, he tino tika, he iti te utu, he pai mō te hanga papatipu, engari he pai ki te hoahoa i te pokepokea ai.
(3). Te whakakorenga NC,: Ko te whakakorenga NC te tuatahi ki te tuhi i te kaupapa miihini CNC, mā te whakamahi i te pūmanawa hōtaka, ka tuhia te tuhi ki te mīhini tukatuka nama NC ka taea te tautuhi i te kaupapa, kia rite ki ēnei kaupapa, me whakamahi maripi ki te pereti, engari ko tōna hanganga he mea tapahi, he iti te utu, he tika te 0.15.
(4). Ko te whakakorenga taiaho, ko te whakamahinga o te tapahi taiaho, ka tapahia te hanganga o te pereti i roto i te pereti nui, nā te mea me tuhi te whakakorenga NC i te kaupapa taiaho, ka taea te whakamahi i ngā momo āhua uaua o ngā wāhanga pereti, he nui te utu, he tika te 0.1.
(5). Mīhini kani: e whakamahia ana i raro i te kōtaha konumohe, te paipa tapawhā, te paipa tūtohi, te rauemi pae porowhita me ētahi atu, he iti te utu, he iti te tika.
