Ndi Njira Zotani Zowonetsetsera ndi Kukulitsa Kulondola kwa Machining?
1) Ukadaulo wopewera zolakwika: kugwiritsa ntchito bwino umisiri wapamwamba ndi zida kuti muchepetse kutengera kolakwika koyambirira kolakwika koyambirira kolakwika koyambirira kolakwika homogenization.
2) Tekinoloje yolipirira zolakwika: kuzindikira kwapaintaneti kwa mphero yofananira yokhayokha yowongolera gawo lalikulu lazolakwitsa.
-Zimachita chiyanimakinapamwamba geometry zikuphatikizapo?
Kukakamira kwa geometric, corrugance yapamtunda, mawonekedwe ake, zolakwika zapamtunda.
-Kodi zinthu zosanjikiza za pamwamba ndi zotani?
1) Cold ntchito kuumitsa pamwamba wosanjikiza zitsulo
2) Metallographic mapindikidwe pamwamba wosanjikiza zitsulo
3) Kupanikizika kotsalira kwazitsulo zosanjikiza pamwamba
-Yesani kusanthula zinthu zomwe zimakhudza makulidwe apamwamba a makina?
1) Mtengo wa roughness uli ndi: kutalika kwa malo otsalira odulidwa.
2) Zinthu zazikulu: nsonga ya arc radius, mbali yayikulu yokhotakhota, kupotoza kwa Angle feed
3) Zinthu zachiwiri: kuonjezera liwiro lodulira, kusankha madzi odulira moyenera ndikuwonjezera chowotcha Ngongole ya chidacho kuti chiwongolere chigwere cha chidacho.
-Unikani zinthu zomwe zimakhudza makulidwe amtundu wa akupera.
1) Zinthu zamtundu wa geometric: kutengera kuchuluka kwa kugaya pazovuta zam'mwamba
2) Mphamvu ya kugaya gudumu granularity ndi kugaya gudumu kuvala pa roughness pamwamba
3) Chikoka cha zinthu zakuthupi: pulasitiki mapindikidwe pamwamba zitsulo wosanjikiza: kusankha akupera mlingo gudumu.
Yesetsani kusanthula zinthu zomwe zimakhudza ntchito yozizira kuuma kwa malo odulidwa?
Chikoka cha kudula magawo chikoka cha chida geometry chikoka cha zinthu katundu
Kodi kupsa mtima ndi chiyani? Kodi kugaya kuzimitsa moto ndi chiyani? Kodi mphesa zowotcha ndi chiyani?
1) Tempering: Ngati kutentha m'dera akupera si upambana kusintha kutentha kwa chitsulo chowumitsidwa, koma kuposa martensite kusintha kutentha, workpiece pamwamba zitsulo martensite adzatembenuzidwa kukhala m'munsi kuuma kwa dongosolo mtima.
2) Kuzimitsa: ngati kutentha m'dera akupera kuposa gawo kusintha kutentha, pamodzi ndi kuzirala zotsatira za coolant, pamwamba zitsulo adzaoneka yachiwiri kuzimitsa martensite dongosolo, kuuma ndi apamwamba kuposa martensite choyambirira; M'munsi mwake, chifukwa cha kuzizira pang'onopang'ono, minofu yotentha yokhala ndi kuuma kochepa kuposa momwe martensite oyambirira amawonekera.
Annealing: Ngati kutentha kwa mphero kupitirira kutentha kwa kusintha kwa gawo ndipo palibe choziziritsa panthawi yopera, chitsulo chapamwamba chimakhala ndi mawonekedwe a annealed ndipo kuuma kwa chitsulo pamwamba kumachepa kwambiri.
