Roughness mata

Ko te roughness mata ko tetahi o nga paearu matua mō te aromātai i te kaha o ngā wāhanga. Whakangaromanga fehangahangai e wahi i raro i te mana o kawenga tāupe e tika ki te tohu nui o te ahotea kukū. Te whakamutunga, i roto i te tahuri, puta ka reira he kōtītiti. Ko te raro te roughness mata, te raro te tūponotanga o te hanganga o kapiti tika ki te rohirohi whakarewa. wāhanga tukatuka (oti, te oro, i mitimiti, me ētahi atu) whai wāhi ki te hua nui o te rohe rohirohi kaha.

Ko te raro te roughness mata, te pai nga āhuatanga anticorrosion o te tūemi. He tino nui i roto i te wā i reira e kore e taea te tukatuka o ngā hua ki te tono i te paninga paruru tenei. Taua taipitopito, i ngā, e taea te pēnei ipurau pūkaha.

Ko roughness mata iti o te faufaa rahi i roto i te pairings e whakatau i nga tikanga o te kawe ia waiariki, tightness. faarahi tenei te kaha ki te whakaata hiko, marama, me te ngaru ultrasonic. I tua atu, riro te mate iti atu i te pūngao hiko i roto i te pūnaha resonating waveguides riro raro electrodes te puritanga; heke rite hau absorption me outgassing i roto i ngā pūrere korehau te whakahaerehia, reira horoi wahi o matūriki puehu adsorbed, kohu, hau.

Kua tuhia Te arotake i tohunga kounga mata te rārangi takotoranga i hanga i muri machining atu maimoatanga ranei. Tenei wae he pānga i runga i te tohu o te kaha o te hononga press, ngā taunga tino mauroa. kia te kaihoahoa kia kōrero whiu arotahi i roto i te wā tino. he hiahia taua kia hei tauira, e ara i roto i te hononga ki te aronga o te kaupapa o te kōpana o hau wai ranei i runga i te workpiece ki te aronga o te nekehanga whanaunga (retireti) o conjugates ranei. Heke kākahu ki te taea iti i ōrite te ahunga o ngā wāhanga pāhiwihiwi ki te aronga retireti.

tutaki tonu te waviness o te mata, me te roughness iti te tika tiketike e he e tika ana ki te tikanga whakahaere o ngā āhuatanga haumi e kore anake, engari ano hoki i runga i te hiahia ki te whiwhi hua pono mō inenga i roto i te ahumahi. Ka taea te whakamahi taua workpieces ki te hanga hua ahua ātaahua ranei ki te whakarato i te haratau o ngā tūemi ihirangi pokekore.

whakamana Measurement o roughness mata e ki te tika. E whakatakotoria Tohu i runga ki te whakaaro mahi o te hua. Ki te kahore e hanga nga whakaritenga mo taipitopito kounga, na e kore e whakamana i te mana i runga i te taumata o te roughness. Me mea te reira kia e kore e te kerēme ngā he aromatawai o hē (aroaro o anga, hei tauira). I roto i tenei whakaaro, i te whakatinanatanga o te mana o te roughness mata, waho mana o te mana o mea kohakore te tino. I roto i ētahi wā, ka taea te whakaturia nga whakaritenga ki nga wahi takitahi o tetahi wahi.

whakamana aro mātai roughness i runga i te kōtītiti kōtaha (nuinga hake). Hei whakaputa i tenei waka rererangi motu. Ki te whakaaro o te wehe i te tahi atu kōtītiti roughness ki kaupae āhua nui, whakamana tona whakamātautau i roto i te tetahi, kaua iti rohe.

whakamana ine rahinga me te māori e ono tawhā. Ko te kupu, tango ki pūkete te tawhā e toru tiketike-ara mo te aromātai i te roughness mata (Ra, RZ, Rmax), e rua stepper (S, Sm), me te taupū, e whakatau i te roa whanaunga o te kōtaha tautoko (TP).
