CNC Machining Zvikanganiso
Iko kukanganisa kwejometri kwekugadzirisa kugadzirisa ndeyekuita kuti workpiece ienzane nechombo uye muchina mudziyo une nzvimbo yakarurama, saka chikanganiso chejometri chekugadzirisa machining kukanganisa (kunyanya kukanganisa kwechinzvimbo) kune simba guru.
Positioning kukanganisa kunyanya inosanganisira datum miscoincidence kukanganisa uye kukanganisa kusiri iko kwekugadzira kwekumisikidza vaviri.Kana iyo workpiece ichigadziriswa pamushini wemuchina, zvinodikanwa kuti usarudze huwandu hwezvinhu zvejometri pane workpiece senzvimbo yekumisikidza datum yekugadzirisa.Kana iyo yakasarudzwa yekumisikidza datum uye dhizaini yedhizaini (iyo datum inoshandiswa kuona saizi yepamusoro uye chinzvimbo pane chikamu chekudhirowa) ikasapindirana, inoburitsa iyo datum mismatch kukanganisa.Nzvimbo yekuwana yeworkpiece uye chinhu chekutsvaga chekugadzirisa zvinoumba peya yekuwana pamwe chete.Chinzvimbo chepamusoro chekusiyana kwechishandiso chinokonzerwa nekugadzirwa kusina kururama kwechikwata chekutsvaga uye mukaha wekubatana pakati pekutsvaga kwekutsvaga kunonzi kukanganisa kwekugadzira kusina kunaka kwekutsvaga peya.Iko kukanganisa kwekugadzira kusakwana kwechikwata chekuisa chinogona kubudiswa chete kana nzira yekugadzirisa inoshandiswa, asi kwete mukuedza kutema nzira.
Process system deformation kukanganisa workpiece kuoma: process system kana iyo workpiece kuomarara inoenderana nemuchina chishandiso, chishandiso, chigadziriso chakaderera, pasi pechiito chekucheka simba, iyo workpiece nekuda kwekushaikwa kwekuomarara kunokonzerwa neiyo deformation.Machining kukanganisayakakura.Kuomarara kwechishandiso: kuoma kwekunze kwedenderedzwa kutendeuka chishandiso mune yakajairika (y) kutungamira kweiyo machining nzvimbo yakakura kwazvo, uye deformation yayo inogona kuregererwa.Kuboora gomba remukati rine dhayamita diki, kuomarara kwebhari rekushandisa kwakashata kwazvo, iyo simba deformation yebhari yekushandisa ine simba guru pakuita machining kwegomba.
Kuomarara kwezvikamu zvemashini emuchina: zvikamu zvemuchina wemuchina unoumbwa nezvikamu zvakawanda.Parizvino, hapana yakakodzera uye yakapusa yekuverenga nzira yekuomarara kwemakina ezvishandiso zvikamu.Parizvino, inonyanya kutsanangurwa nekuedza nzira.Izvo zvinhu zvinopesvedzera kuomarara kwemakina ezvishandiso zvikamu zvinosanganisira kusangana deformation yejoint surface, friction force, yakaderera kuomarara zvikamu uye clearance.
Iko kukanganisa kwejometri yechombo chero chigadziro chekucheka hachidzivisiki kubudisa kupfeka, uye nokudaro kunokonzera ukuru uye chimiro che workpiece kuchinja.Kupesvedzera kwechishandiso chikanganiso che geometric pane machining kukanganisa kunosiyana nemhando dzakasiyana dzezvishandiso: kana uchishandisa yakagadziriswa-saizi yekucheka maturusi, kukanganisa kwekugadzira kwechishandiso kuchakanganisa zvakananga kurongeka kwechishandiso;Nekudaro, kune yakajairika chishandiso (senge chekushandura chishandiso), kukanganisa kwekugadzira hakuna mhedzisiro yakananga pakukanganisa kwekugadzira.
