Ukwenziwa kwemishini ye-CNC yezingxenye ezincane zensiza yezokwelapha kuyinqubo eyinkimbinkimbi kakhulu futhi edinga ngobuchwepheshe.Akubandakanyi nje kuphela okokusebenza okunembayo okuphezulu nobuchwepheshe, kodwa futhi kudinga ukucatshangelwa kokukhethekile kwezinto zokwakha, ukuhluzeka kokuklama, ukwenziwa kahle kwamapharamitha wenqubo, nokulawulwa kwekhwalithi okuqinile.Lesi sihloko sizohlola ukuthi ungabhekana kanjani nalezi zinkinga nokuthi ungabhekana kanjani nazo.
Okuqukethwe
1.Izinselelo zokuklama nentuthuko
2.Izidingo zokunemba okuphezulu nokunemba
3.Izinselele zezinto ezibonakalayo
4.Ukuguga kwamathuluzi nokulawula amaphutha
5.Process ipharamitha nokwenza kahle
6.Ukulawula iphutha nokulinganisa
1.Izinselelo zokuklama nentuthuko
Ukuklanywa nokuthuthukiswa komshini wezokwelapha kuyisigaba esibalulekile sokuphumelela kwawo.Imishini yezokwelapha eklanywe ngendlela engafanele iyehluleka ukuhlangabezana nezimfuneko zokulawula futhi ayikwazi ukulethwa emakethe.Ngakho-ke, inqubo yokucutshungulwa kwezingxenye zezokwelapha ze-CNC idinga ukuhlanganiswa eduze nokunengqondo kanye nokuba nokwenzeka komklamo womkhiqizo.Ukuqinisekisa ukuthobela imithetho nezindinganiso ezifanele embonini yokukhiqiza idivayisi yezokwelapha, abacubunguli bezingxenye badinga ukuthola izitifiketi ezidingekayo, njengamalayisense okukhiqiza idivayisi yezokwelapha kanye nezitifiketi zesistimu yokuphatha ikhwalithi.
2.Izidingo zokunemba okuphezulu nokunemba
Lapho ukukhiqiza izimila zomzimba ezifana nokushintshwa kwe-hip kanye nokufakelwa kwamadolo, ukunemba okuphezulu kakhulu nokunemba kuyadingeka.Lokhu kungenxa yokuthi ngisho namaphutha amancane omshini angaba nomthelela omkhulu empilweni nasenhlalakahleni yesiguli.Isikhungo semishini ye-CNC singakwazi ukukhiqiza ngokunembile izingxenye ezihlangabezana nezidingo zesiguli ngamamodeli e-CAD futhi zihlehlise ubuchwepheshe bobunjiniyela ngokusekelwe ezidingweni zodokotela abahlinzayo bamathambo, bathole ukubekezelelana okuncane njengo-4 μm.
Imishini evamile ye-CNC ingase ibe nzima ukuhlangabezana nezidingo mayelana nokunemba kokucubungula, ukuqina nokulawula ukudlidliza.Osayizi besici bezingxenye ezincane ngokuvamile basezingeni le-micron, elidinga okokusebenza okunokunemba kokuma okuphindaphindekayo okuphakeme kakhulu nokunemba kokulawula ukunyakaza.Lapho ucubungula izingxenye ezincane, ukudlidliza okuncane kungaholela ekuncishisweni kwekhwalithi yendawo kanye nobukhulu obungalungile.Ukucutshungulwa kwe-CNC yezingxenye ezincane zemishini yezokwelapha kudinga ukukhetha amathuluzi omshini we-CNC anokulungiswa okuphezulu kanye nezinhlelo zokulawula impendulo ezinembayo, njengamathuluzi omshini wama-eksisi amahlanu, asebenzisa ama-spindle anesivinini esiphezulu ane-levitation yomoya noma ubuchwepheshe be-levitation magnetic ukuze kuncishiswe ukungqubuzana nokudlidliza.
3.Izinselele zezinto ezibonakalayo
Imboni yezokwelapha idinga izimila ukuba zenziwe ngezinto ezihambisana ne-biocompatible ezifana ne-PEEK nama-titanium alloys.Lezi zinto zivame ukukhiqiza ukushisa okukhulu ngesikhathi sokucutshungulwa, futhi ukusetshenziswa kwezinto ezipholile ngokuvamile akuvunyelwe ngenxa yokukhathazeka mayelana nokungcola.Amathuluzi omshini we-CNC adinga ukuhambisana nezinto ezihlukahlukene zokusingatha lezi zinto eziyinselele, kanye nokulawula ukushisa ngokuphumelelayo futhi agweme ukungcoliswa ngesikhathi somshini.
Ukwenza imishini ye-CNC yezingxenye ezincane zedivayisi yezokwelapha kudinga ucwaningo nokuqonda izici zezinto ezihlukile zebanga lezokwelapha, okuhlanganisa izinsimbi, amapulasitiki nezitsha zobumba, nokusebenza kwazo kumashini we-CNC.Thuthukisa amasu omshini ohlosiwe kanye nemingcele, njengesivinini esifanelekile sokusika, amanani okuphakelayo nezindlela zokupholisa, ukuze ivumelane nezidingo zezinto ezihlukene.
4.Ukuguga kwamathuluzi nokulawula amaphutha
Uma i-CNC icubungula izingxenye ezincane, ukugqokwa kwamathuluzi kuzothinta ngqo ikhwalithi yokucubungula.Ngakho-ke, izinto ezithuthukisiwe zamathuluzi kanye nobuchwepheshe bokumboza, kanye nokulawula amaphutha okunembile kanye nobuchwepheshe bokulinganisa, kuyadingeka ukuze kuqinisekiswe ukunemba ngesikhathi somshini nokuqina kwamathuluzi.Ukusebenzisa izinto zamathuluzi eziklanywe ngokukhethekile njenge-cubic boron nitride (CBN) ne-polycrystalline diamond (PCD), kanye nezindlela ezifanele zokupholisa nokugcobisa, kunganciphisa ukwakheka kokushisa nokuguga kwamathuluzi.
I-CNC machining yezingxenye ezincane zezokwelapha ikhetha futhi isebenzisa izisiki ezincane kanye nezinto ezinembile eziklanyelwe ukusetshenzwa kwezingxenye ezincane.Sethula isistimu yekhanda eshintshashintshayo ukuze ivumelane nezidingo ezihlukene zokucubungula, ukunciphisa isikhathi sokushintsha ithuluzi nokuthuthukisa ukuguquguquka kokucubungula.
5.Process ipharamitha nokwenza kahle
Ukuze uthuthukise ikhwalithi yokucubungula nokusebenza kahle kwezingxenye ezincane, kuyadingeka ukwandisa imingcele yenqubo, njengesivinini sokusika, isivinini sokuphakelayo nokujula kokusika.Lawa mapharamitha athinta ngqo ikhwalithi yendawo eyenziwe ngomshini kanye nokunemba kobukhulu:
1. Isivinini sokusika: Isivinini esikhulu kakhulu sokusika singabangela ukushisa kwethuluzi nokwenyuka kokuguga, kuyilapho isivinini esiphansi kakhulu sizonciphisa ukusebenza kahle kokucubungula.
2. Isivinini sokuphakelayo: Uma isivinini sokuphakelayo siphezulu kakhulu, sizobangela kalula ukuvaleka kwe-chip kanye nendawo yokucubungula engalungile.Uma isivinini sokuphakelayo siphansi kakhulu, sizothinta ukusebenza kahle kokucubungula.
3. Ukujula kokusika: Ukujula okusika ngokweqile kuzokwandisa umthwalo wamathuluzi, okuholela ekugugekeni kwamathuluzi namaphutha omshini.
Ukwenziwa kahle kwalezi zinhlaka kudinga ukuthi kusekelwe ezintweni ezibonakalayo zento kanye nokusebenza kwezisetshenziswa zokucubungula.Amapharamitha wenqubo angathuthukiswa ngokuhlolwa nokulingiswa ukuze kutholwe izimo ezingcono kakhulu zokusika.
6.Ukulawula iphutha nokulinganisa
Ubukhulu besici bezingxenye ezincane zezokwelapha buncane kakhulu, futhi izindlela zokulinganisa zendabuko azikwazi ukuhlangabezana nezidingo.Amathuluzi okulinganisa okusebenza okunemba okuphezulu nokuxhumanisa imishini yokulinganisa (CMM) ayadingeka ukuze kuqinisekiswe ikhwalithi yokucubungula.Izinyathelo eziphikisanayo zihlanganisa ukuqapha kwesikhathi sangempela kanye nokunxeshezelwa kwamaphutha ngesikhathi sokucubungula, ukusetshenziswa kwemishini yokulinganisa enembe kakhulu ukuze kuhlolwe ucezu lomsebenzi, nokuhlaziywa kwamaphutha okudingekayo kanye nesinxephezelo.Ngesikhathi esifanayo, ukulawulwa kwenqubo yezibalo (SPC) nezinye izinqubo zokuphatha ikhwalithi kufanele zisetshenziswe ukuze kuqashwe ngokuqhubekayo inqubo yokukhiqiza nokwenza izinguquko ngesikhathi.
I-GPM igxile ezinsizakalweni zokucubungula ze-CNC zezingxenye zemishini yezokwelapha ezinembayo.Ihlanganise uchungechunge lwemishini yokukhiqiza esezingeni eliphezulu kanye namaqembu ezobuchwepheshe.Iphumelele isitifiketi se-ISO13485 yesistimu yokuphathwa kwekhwalithi yedivayisi yezokwelapha ukuze iqinisekise ukuthi inikeza imikhiqizo namasevisi amahle kakhulu ekhasimendeni ngalinye futhi izimisele ukuhlinzeka amakhasimende ngezinga elingcono kakhulu.
