Lingaliro la roughness pamwamba
Kuuma kwa pamwamba kumatanthawuza kusagwirizana kwa malo opangidwa ndi makina okhala ndi mipata yaying'ono ndi nsonga zazing'ono ndi zigwa. Mtunda (mtunda wa mafunde) pakati pa nsonga zake ziwiri kapena zigwa ndizochepa kwambiri (pansi pa 1mm), zomwe ndi zolakwika zazing'ono za mawonekedwe a geometric.Mwachindunji, amatanthauza kutalika ndi katayanitsidwe ka S kachigwa chaching'ono chapamwamba cha Z. Chogawidwa ndi S:
S<1mm ndi roughness pamwamba;
1 ≤ S ≤ 10mm ndi waviness;
S＞ 10mm ili mu mawonekedwe a f.
二·Chochititsa chachikulu cha roughness pamwamba pa zigawo
Zimakhudza kukana kuvala. Kuchuluka kwa pamwamba, kumachepetsanso malo olumikizana bwino pakati pa malo okwerera, kupanikizika kwakukulu, kusagwirizana kwakukulu, komanso kuvala mofulumira.
Zimakhudza kukhazikika kwa zoyenera. Kuti chiwongolero chikhale chokwanira, pamwamba pake, ndizovuta kwambiri kuvala, zomwe zimapangitsa kuwonjezeka kwapang'onopang'ono kwa chilolezo panthawi yogwira ntchito; Pofuna kusokoneza, chifukwa nsonga zazing'onoting'ono zimafinyidwa lathyathyathya panthawi ya msonkhano, kusokoneza kwenikweni kumachepetsedwa ndipo mphamvu yolumikizira imachepetsedwa.
Kumakhudza kutopa mphamvu. Pali mbiya zazikulu pamwamba pa ziwalo zolimba, zomwe, monga nsonga zakuthwa ndi ming'alu, zimakhudzidwa ndi kupsinjika maganizo ndipo motero zimakhudza mphamvu ya kutopa kwa ziwalozo.
Imakhudza kukana dzimbiri. Pamwamba pazigawo zing'onozing'ono zimatha kupangitsa kuti mpweya wowononga kapena zamadzimadzi zilowe mkati mwachitsulo kudzera m'mizere yowoneka bwino yomwe ili pamtunda, zomwe zimapangitsa kuti pakhale dzimbiri.
Zimakhudza ntchito yosindikiza. Malo osalimba sangagwirizane bwino, ndipo gasi kapena madzi amatuluka kudzera pamipata pakati pa malo okhudzana.
Zimakhudza kuuma kolumikizana. Kulumikizana kolimba ndi kuthekera kwa olowa pamwamba pa chigawo chimodzi kukana kukhudzana mapindikidwe pansi mphamvu zakunja. Kuuma kwa makina makamaka kumadalira kuuma kolumikizana pakati pa magawo osiyanasiyana.
Zimakhudza kulondola kwa kuyeza. Kukula kwapamtunda kwa gawo loyezera la gawolo ndi malo oyezera a chida choyezera kumakhudza mwachindunji kulondola kwa kuyeza, makamaka muyeso yolondola.
Komanso, pamwamba roughness ndi milingo yosiyanasiyana ya chikoka ❖ kuyanika, matenthedwe madutsidwe ndi kukhudzana kukana, kunyezimiritsa ndi ma radiation katundu, kukana madzi ndi mpweya otaya, ndi otaya panopa padziko kondakitala mbali.
