Ixabiso lesiqwenga lalinxulunyaniswa neeyure zabantu ezichithwe ekudalweni kwaso. Nangona kunjalo, inkulungwane yama-21 ingenise ixesha elitsha kule misebenzi yakudala. Ukuhlanganiswa komatshini wokulawula amanani ekhompyutha (CNC) akusiyo nje intuthuko eqhubekayo; yinkcazo esisiseko yendlela ezicwangciswe kwaye zenziwe ngayo iindawo zesinyithi ezixabisekileyo.

Umatshini wokwenza izinto nge-CNC, inkqubo yokwenziwa kwezinto ezingaphantsi apho izixhobo ezilawulwa yikhompyutha zisusa izinto kwibhloko eqinileyo, iguqula imveliso yobucwebe. Idibanisa umsantsa phakathi kombono ontsonkothileyo wegcisa kunye nokuchaneka kobuchwepheshe banamhlanje bemizi-mveliso. Eli nqaku lijonga kwiinkalo zobugcisa zolu tshintsho, lihlola oomatshini, izixhobo, imisebenzi yokusebenza, iingenelo, kunye namathuba exesha elizayo oomatshini bokwenza izinto nge-CNC kwiindawo zesinyithi ezixabisekileyo.

1. Indlela yokusebenza ye-CNC: Ukusuka kwiDijithali yoMbono ukuya kwiFomu yoBume

Uhambo lwento yokuhombisa eyenziwe ngomatshini we-CNC aluqali ebhentshini, kodwa luqala kwisikrini sekhompyutha. Le nkqubo ingumdibaniso ongenamthungo woyilo lwedijithali kunye nokwenziwa kwezinto ezibonakalayo, ngokuqhelekileyo kulandela amanqanaba amathathu aphambili:

a) Ukumodela kweCAD (Uyilo oluNcedwa yiKhompyutha): Umzobi okanye umyili usebenzisa isoftware ekhethekileyo efana neRhinoGold, iMatrixGold, okanye iBlender ukwenza imodeli ye-3D eneenkcukacha ezininzi yesiqwenga sobucwebe. Le ndawo yedijithali inika inkululeko engenakuthelekiswa nanto. Iijometri ezintsonkothileyo, ukunqunyulwa okungaphantsi, useto olulinganayo ngokugqibeleleyo, kunye nobume obuntsonkothileyo obunokuba nzima kakhulu okanye obungenakwenzeka ukubusebenzisa ngesandla bunokwenziwa ngendlela echanekileyo. Umyili unolawulo olupheleleyo kuyo yonke i-micron yoyilo, eqinisekisa ukuba isiqwenga sokugqibela siya kuba yikopi echanekileyo yenkosi yedijithali.

b) Ukwenziwa kweeNkqubo zeCAM (Ukwenziwa kweeMveliso eziNcedwa yiKhompyutha): Nje ukuba imodeli ye-3D igqityiwe, ingeniswa kwisoftware ye-CAM. Kulapho imodeli yedijithali iguqulelwa khona kulwimi olunokuqondwa ngumatshini we-CNC—ikhowudi ye-G. Umcwangcisi we-CAM uchaza lonke icebo loomatshini. Oku kuquka:

• Ukuveliswa kweNdlela yeZixhobo: Le software ibala iindlela ezisebenzayo zokususa izinto kwaye ityhile imo yokugqibela. Oku kubandakanya ukurhabaxa (ukususa izinto ezinkulu ngokukhawuleza) kunye nokugqiba ukurhabaxa (ukufezekisa iinkcukacha zomphezulu wokugqibela kunye nokugudama).

• Ukukhethwa kwesixhobo: Umcwangcisi wenkqubo ukhetha izixhobo ezifanelekileyo kwithala leencwadi elikhulu. Kwizinto zokuhombisa, ezi zihlala zizixhobo zokuhombisa ezincinci kakhulu, izixhobo zokuhombisa ibhola, kunye neengraving bits, ngamanye amaxesha zincinci njenge-0.1 mm ububanzi, ezenziwe nge-micro-grain carbide ukumelana namandla okusika iintsimbi ezinzima.

• Icebo Lokulungisa: Kufuneka kwenziwe isicwangciso sokugcina ngokukhuselekileyo iqhekeza elincinci nelibizayo lesinyithi esixabisekileyo. Oku kudla ngokubandakanya imihlathi ethambileyo eyenziwe ngokwezifiso yesiciko, iteyiphu enamacala amabini, okanye izixhobo ezikhethekileyo ezibamba izinto ezisuka ezantsi okanye emacaleni, nto leyo evumela umatshini ukuba afikelele phezulu nakumacala onke esixhobo somsebenzi.

• Ubunzima kunye nokuLungiseka: Igolide ecocekileyo, isilivere, kunye neplatinum zithambile kakhulu kwaye “ziyi-gummy.” Endaweni yokwenza iitships ezincinci ezicocekileyo nezikhutshwa lula, izinto ezisetyenziswayo zidla ngokungcolisa, zikrazule, kwaye zinamathele kwisixhobo sokusika. Le nto, eyaziwa ngokuba yiBuilt-Up Edge (BUE), inokonakalisa isixhobo kunye nomgangatho womphezulu wesixhobo somsebenzi. Ukulwa noku, abenzi bezinto zokuhombisa badla ngomatshini ii-alloys (ezifana negolide ye-14k okanye ye-18k) eziqinileyo kwaye ziqhekeka ngakumbi ngenxa yokubakho kobhedu, isilivere, kunye nezinye izinyithi. Nangona kunjalo, kufuneka izixhobo ezibukhali kakhulu kunye neeparameter ezithile zokusika.

• Ukuqina komsebenzi: Ezinye ii-alloys zesinyithi ezixabisekileyo, ingakumbi iintsimbi ezithile ezingenasici ezisetyenziswa ekwenzeni iiwotshi ezikumgangatho ophezulu kunye nezinye ii-alloys zeplatinum, zisebenza ngokukhawuleza. Ukuba ukusika kukhaphukhaphu kakhulu, isixhobo siya kukhuhla kumphezulu endaweni yokuwusika, siqinise ngoko nangoko izinto kwaye senze ukusika okulandelayo kube nzima. Oku kufuna ifilosofi "yokuthatha ukusika ngokwenene", apho isixhobo sithatha izinto ngomthwalo owaneleyo wokusika, kungekhona ukutsha.

• Indalo Erhabaxa: Nangona igolide ecocekileyo ithambile, uninzi lwezinto ezidityanisiweyo ezisetyenziselwa ukunika umbala kunye namandla zinokuba rhabaxa kakhulu. Umzekelo, ubhedu olukwigolide yerose okanye i-nickel ekwigolide emhlophe zinokubangela ukuguguleka okukhulu kwezixhobo. Oku kufuna ukusetyenziswa kweengubo ezisemgangathweni ophezulu, ezingagugiyo ezifana ne-AlTiN (Aluminium Titanium Nitride) kwizixhobo ze-carbide ukuze zandise ubomi bazo.

• Iindleko Zezinto Eziphezulu: Mhlawumbi owona mngeni ucacileyo lixabiso lezinto eziluhlaza. Ibhloko encinci yeplatinum ingaxabisa amawaka eedola. Impazamo enye yokuprograma okanye ukwaphuka kwezixhobo kunokubangela ilahleko epheleleyo yolo tyalo-mali. Oku kubeka ixabiso elikhulu ekuthembekeni kwenkqubo, ukulinganisa, kunye "nokubonisa" inkqubo kwizinto ezingabizi kakhulu ezifana nobhedu okanye iwax ngaphambi kokuba uzibophelele kwisitokhwe sesinyithi esixabisekileyo.

4. Ukuchaza ngokutsha imveliso: Iingenelo kuneendlela zemveli

Ukwamkelwa koomatshini bokuchwetheza be-CNC kunika iingenelo ezinomtsalane ngaphezu kweendlela zokwenza ubucwebe bendabuko, ngakumbi ukwenziwa kwe-casting kunye nokwenziwa ngesandla.

• Ukuchaneka Okungaguqukiyo Nokuphindaphindwa: Umatshini we-CNC uza kuvelisa isiqwenga se-100 xa ubaleka ngesantya esifanayo nesokuqala. Oku kubaluleke kakhulu kwiziqwenga ezifuna ukulingana ngokugqibeleleyo, njengekhava yewotshi yodidi oluphezulu, unxibelelwano oluntsonkothileyo kwisongo, okanye indawo yelitye apho ilitye elinqabileyo kufuneka lihlale licocekile. Eli nqanaba lokuhlala liqinile akunakwenzeka ukulifezekisa nge-lost-wax casting, enokuncitshiswa kunye nokutshintsha kwe-mold.

• Ubunzima boYilo kunye neJiometri "engenakwenzeka": Umatshini wokugaya we-CNC ukhulula umyili kwiingxaki ezininzi zokwenziwa kwemveli. Iimpawu ezifana neekona zangaphakathi ezibukhali, iindawo ezithe tyaba ngokupheleleyo, ukukrolwa okunzulu, kunye neekhonteyina ze-3D ezinzima zinokucutshungulwa ngokuthe ngqo. Uyilo olungenakukwazi ukucutshungulwa okanye oluthatha ixesha elide kakhulu ukuba lwenziwe ngesandla luba luncedo ngokwezoqoqosho.

• Ukunyaniseka kwezinto kunye nobuninzi bazo: Ukubumba ngamanye amaxesha kunokungenisa imingxunya—amaqamza omoya amancinci abanjwe ngaphakathi kwesinyithi—anokwenza buthathaka isiqwenga okanye onakalise umphezulu waso ngexesha lokupolisha. Ekubeni umatshini wokugaya we-CNC uqala ngentsimbi eqinileyo, eyenziweyo eqengqiweyo okanye etsaliweyo, inxalenye ephumayo inesakhiwo esifanayo, esixineneyo seenkozo. Oku kubangela imveliso yokugqibela eqinileyo, ehlala ixesha elide enobuchule bokupolisha obuphezulu kunye nokukhazimla.

• UkuNcitshiswa kwePost-Processing: Inkqubo yoomatshini be-CNC eyenziwe kakuhle inokuvelisa inxalenye esele ilungele ukugqitywa kokugqibela. Imiphezulu igudile, imiphetho icocekile, kwaye iinkcukacha zichaziwe kakuhle. Oku kunciphisa kakhulu iiyure zokusila ngesandla, ukufayilisha, kunye nokupolisha ezifunekayo kwiziqwenga ezenziwe ngesandla okanye ezenziwe ngesandla, nto leyo eyenza kube lula ixesha lokuvelisa.

5. Ikamva Elisebenzisanayo: I-CNC kunye neGcisa
