1. Imigaqo yenkqubo kunye neenzuzo
Inkqubo yomgaqo
Umatshini we-CNC ulawula ngokuchanekileyo ukuhamba kwezixhobo zoomatshini kunye nokusikwa kwezixhobo zokusika ngokusebenzisa inkqubo yokulawula idijithali yekhompyutheni, kwaye yenza ukusika, ukubhola, ukugaya, kunye neminye imisebenzi yomatshini kwizinto zetsimbi ngokweenkqubo zokubhala kwangaphambili. Isenokwenza kancinci kancinci isiqwenga sentsimbi ekrwada ibe ngamacandelo okanye iimveliso ezinemilo entsonkothileyo kunye nemilinganiselo echanekileyo.
inzuzo
Ukuchaneka okuphezulu: okukwazi ukufikelela kwinqanaba le-micrometer okanye ukuchaneka okuphezulu, ukuqinisekisa ukuchaneka kunye nokuhambelana kwemilinganiselo yemveliso. Oku kwenza ukuba iimveliso zetsimbi ze-CNC zikwazi ukuhlangabezana nemeko yosetyenziso echanekileyo, efana ne-aerospace, izixhobo zonyango, kunye nezinye iinkalo.
Ubume bokucwangcisa ubume obuntsonkothileyo: Inokwenza ngokulula iimilo ezahlukeneyo zejiyometri ezintsonkothileyo, nokuba zizigophe, umphezulu, okanye iindawo ezineempawu ezininzi, inokuveliswa ngokuchanekileyo. Oku kubonelela ngenkululeko enkulu yoyilo lwemveliso, ukuvumela abayili ukuba bafezekise uyilo oluninzi.
Ukusebenza okuphezulu kwemveliso: Emva kokuba inkqubo yokucwangcisa isetyenzisiwe, isixhobo somatshini sinokuqhuba ngokuqhubekayo kwaye ngokuzenzekelayo, siphucula kakhulu ukusebenza kakuhle kwemveliso. Xa kuthelekiswa neendlela zemveli zokwenza, CNC machining inokuvelisa iimveliso ezininzi ngexesha elifutshane.
Ukulungelelaniswa kwezinto ezibanzi: ezifanelekileyo kwizinto ezahlukeneyo zetsimbi, ezifana ne-aluminium alloy, insimbi engenasici, i-titanium alloy, njl. Izinto ezahlukeneyo zetsimbi zingakhethwa ngokweemfuno zokusebenza kunye neemeko zesicelo semveliso, ukwenzela ukuhlangabezana neemfuno zabathengi abahlukeneyo.
2, Ukuqhubekekisa ukuhamba
Uyilo kunye neNkqubo
Okokuqala, ngokusekelwe kwiimfuno zomthengi okanye imizobo yoyilo lwemveliso, iCAD yobuchwephesha (uyilo oluncediswa yikhompyuter) kunye ne-CAM (imveliso encediswa yikhompyuter) isetyenziselwa ukuyila imveliso kunye nokubhala inkqubo yomatshini. Kwinkqubo yoyilo, iinjineli kufuneka ziqwalasele izinto ezifana nokusebenza kwemveliso, ulwakhiwo, kunye neemfuno ezichanekileyo, kwaye ziguqulele ezi mfuno kwiinkqubo ezithile zomatshini kunye neendlela zesixhobo.
Emva kokugqitywa kweprogram yomatshini, ukuqinisekiswa kokulinganisa kuyafuneka ukuze kuqinisekiswe ukuchaneka kunye nokuba nokwenzeka kweprogram. Ngokulinganisa inkqubo yomatshini, imiba enokubakho efana nokungqubana kwezixhobo kunye nesibonelelo esingonelanga somatshini sinokuchongwa kwangaphambili, kwaye ulungelelwaniso oluhambelanayo kunye nokulungiswa kunokwenziwa.
iivenkile zokugcina
Khetha imathiriyeli yentsimbi efanelekileyo ngokweemfuno zemveliso kwaye uyinqumle ngokweesayizi ezifanelekileyo kunye neemilo njengemathiriyeli ekrwada yokusetyenzwa.
