Iprototyping luluvo olukhulu lokuvavanya uyilo lwakho ngaphambi kokudala imodeli elungele imveliso. I-3D Printers kunye ne-CNC Machining zombini iinketho ezinokubakho, kodwa nganye ineenzuzo kunye nemida eyahlukileyo esekelwe kwiiparamitha zeprojekthi ezahlukeneyo. Ngoko ke yeyiphi eyona ndlela ingcono? Ukuba ukule conundrum, ke eli nqaku kanye into oyifunayo. Siza kuntywila nzulu kuzo zombini iitekhnoloji kwaye sixoxe ngezinto ezininzi eziphambili zokukunceda wenze isigqibo malunga nokuba yeyiphi eyona ilungileyo ngokusekwe kwiimfuno zakho zeprojekthi.
Kule posi siza kugubungela:
3D Printing vs. CNC Machining: Yintoni Umahluko?
Ngaphambi kokuba sitsibe kwizinto ezithile, ukubamba kakuhle izinto ezisisiseko kokona kulungileyo. Umahluko ophambili phakathi koshicilelo lwe-3D kunye ne-CNC Machining yindlela imveliso yokugqibela ephunyezwa ngayo.
Ushicilelo lwe-3D yinkqubo yokuvelisa ezongezelelweyo. Oku kuthetha ukuba isiphelo semveliso yenziwe ngumshicileli we-3D ebeka phantsi iileya ezilandelelanayo zemathiriyeli kwipleyiti yokusebenza de kube ubume bokugqibela bemveliso buphunyeziwe.
I-CNC Machining, kwelinye icala, yinkqubo yokuvelisa i-subtractive. Uqala ngebhloko yemathiriyeli ebizwa ngokuba yi-blank kunye nomatshini kude okanye ususe imathiriyeli ukuba ishiywe nemveliso yokugqibela.
Unokukhetha njani okona kulungileyo kwiimfuno zakho zeprojekthi?
Nganye kwezi zixhobo zimbini zokuvelisa zineengenelo ezahlukileyo kwiimeko ezithile. Makhe sijonge nganye nganye.
1. Umbandela
Xa usebenza ngesinyithi, Oomatshini beCNC ube nenzuzo ecacileyo. Ushicilelo lwe-3D lulonke lugxile kakhulu kwiiplastiki. Kukho iteknoloji yoshicilelo lwe-3D enokushicilela isinyithi, kodwa ngokwembono yeprototyping, inokubiza kakhulu njengoko abo matshini bamashishini banokubiza ngaphezulu kwe-100,000 yeedola.
Enye i-downside ene-3D yoshicilelo lwesinyithi kukuba imveliso yakho yokugqibela ayisandi kakuhle njengenxalenye efanayo eyenziwe ngokukhupha i-blank blank. Unokuphucula amandla enxalenye yentsimbi eprintiweyo ye-3D ngokuphathwa kobushushu, okunokubangela ukuba ixabiso elipheleleyo liphakame. Ngokumalunga ne-superalloys kunye ne-TPU, kufuneka uhambe kunye noshicilelo lwe-3D.
2. Umthamo wemveliso kunye neendleko
Ukuba ujonge kwiprototypes enye ekhawulezayo okanye umthamo ophantsi wemveliso (amanani aphantsi aphindwe kabini), ke ushicilelo lwe-3D lutshiphu. Kwimiqulu yemveliso ephezulu (amadijithi aphindwe kabini ukuya kumakhulu ambalwa), ukugaya i-CNC yindlela yokuhamba.
Iindleko zangaphambili zemveliso eyongezayo zihlala zisezantsi kunemveliso ethotywayo yeprototypes enye. Oko kuthethiweyo, zonke iindawo ezingadingi iijiyometri ezintsonkothileyo zinokuveliswa ngexabiso elithe kratya kusetyenziswa umatshini we-CNC.
Ukuba ujonge imithamo yemveliso engaphezulu kweeyunithi ezingama-500, ubuchwephesha bokwenza isiko obufana nokubumba ngesitofu bunoqoqosho kakhulu kunolwakhiwo olongezelelweyo noluthabathayo.
3. Uyilo oluyinkimbinkimbi
Zombini itekhnoloji inesabelo sazo sokulinganiselwa, kodwa kulo mongo, ukuprintwa kwe-3D kunenzuzo ecacileyo. Umatshini we-CNC awunakukwazi ukusingatha iijiyometri ezintsonkothileyo ngenxa yezinto ezinjengofikelelo lwesixhobo kunye nokukhutshwa, abanini bezixhobo, kunye neendawo zokunyuka. Kananjalo awukwazi ukwenza iikona ezisikwere ngenxa yejiyometri yesixhobo. Ushicilelo lwe-3D luvumela ukuguquguquka okuninzi xa kuziwa kwijometri entsonkothileyo.
Omnye umba omawuqwalaselwe bubungakanani benxalenye oyiprototyping. Oomatshini be-CNC bafaneleka ngakumbi ukuphatha iindawo ezinkulu. Ayikuko ukuba abekho abashicileli be-3D phaya abangekho bakhulu ngokwaneleyo, kodwa ngokwembono yokuchwetheza, iindleko ezinxulumene nomshicileli omkhulu we-3D zibenza bangenzeki kulo msebenzi.
4. Ukuchaneka komlinganiso
Kwiindawo ezifuna ukunyamezela okuqinileyo, i-CNC machining lukhetho olucacileyo. Ukugaya i-CNC kunokufikelela kumanqanaba okunyamezela phakathi kwe-± 0.025 - 0.125 mm. Ngaxeshanye, abashicileli be-3D baqhele ukuba ne- ± 0.3 mm unyamezelo. Ngaphandle kwe Direct Metal Laser Sintering (DMLS) abashicileli abanokufikelela unyamezelo olusezantsi njenge ± 0.1 mm, obubuchwephesha buyindlela ebiza kakhulu kwiprototyping.
5. Ukugqitywa komphezulu
I-CNC machining lukhetho olucacileyo ukuba ukugqitywa komphezulu ongaphezulu kuyinqobo ebalulekileyo. Abashicileli be-3D banokuvelisa ukulingana okuhle kunye nokugqiba, kodwa UMatshini we-CNC yindlela yokuhamba ukuba ufuna umphezulu ongaphezulu ugqibo ukuze udibane namanye amalungu achanekileyo aphezulu.
Isikhokelo Esenziwe Lula ukukunceda ukuba ukhethe
Nasi isikhokelo esikhawulezayo sokukunceda wenze isigqibo phakathi koshicilelo lwe-3D kunye nomatshini we-CNC:
- Ukuba ujonge iprototyping ekhawulezayo, ebandakanya ijometri entsonkothileyo yeprototype enye okanye imveliso encinci kakhulu, ushicilelo lwe-3D luya kuba lolona khetho lufanelekileyo.
- Ukuba ujonge imveliso ephezulu eqhutywayo kumakhulu ambalwa amacandelo aneejometri ezilula, hamba kunye ne-CNC machining.
- Ukuba sijonga ukusebenza kunye nesinyithi, ngoko ke ukusuka kumbono weendleko, i-CNC machining inenzuzo. Oku kubambe nakwizixa eziphantsi. Nangona kunjalo, imida yejometri isasebenza apha.
- Ukuba ukuphindaphinda, ukunyamezelana okuqinileyo, kunye nokugqitywa komphezulu ogqibeleleyo kubekwe phambili kakhulu, hamba kunye nomatshini we-CNC.
Igama lokugqibela
Ushicilelo lwe-3D luseyitekhnoloji entsha noko, kwaye idabi layo lokulawula imarike lisandula ukuqalisa. Ewe, kukho oomatshini boshicilelo be-3D ababizayo kunye nabakumgangatho ophezulu oye wanciphisa umsantsa kwinto eyenziwa yi-CNC machining, kodwa kwimbono yeprototyping, ayinakuqwalaselwa apha. Akukho ubungakanani obunye obulingana naso sonke isisombululo. Ukukhetha enye phezu komnye kuxhomekeke ngokupheleleyo kwiinkcukacha zoyilo lweprojekthi yakho.
