Makina a CNC azigawo zing'onozing'ono za chipangizo chachipatala ndizovuta kwambiri komanso zomwe zimafunikira mwaukadaulo.Sikuti zimangotengera zida ndi ukadaulo wapamwamba kwambiri, komanso zimafunikanso kuganizira za kukhazikika kwa zida, kumveka bwino kwa kapangidwe kake, kukhathamiritsa kwa magawo azinthu, komanso kuwongolera bwino kwambiri.Nkhaniyi ifotokoza mmene tingathanirane ndi mavutowa komanso mmene tingawathetsere.
Zamkatimu
1.Zovuta za mapangidwe ndi chitukuko
2.Zofunikira zolondola komanso zolondola
3.Zovuta zakuthupi
4.Tool wear and error control
5.Process parameter kukhathamiritsa
6.Kuwongolera zolakwika ndi kuyeza
1.Zovuta za mapangidwe ndi chitukuko
Mapangidwe ndi chitukuko cha chipangizo chachipatala ndi gawo lofunika kwambiri kuti apambane.Zipangizo zamankhwala zopangidwira molakwika zimalephera kukwaniritsa zofunikira zowongolera ndipo sizingabweretsedwe kumsika.Choncho, ndondomeko ya CNC processing mbali zachipatala ayenera kuphatikizidwa kwambiri ndi zomveka ndi kuthekera kwa kapangidwe mankhwala.Kuti zitsimikizire kuti zikutsatira malamulo ndi miyezo yoyenera pamakampani opanga zida zachipatala, ma processor a magawo amayenera kupeza ziphaso zofunikira, monga ziphaso zopanga zida zachipatala ndi zitsimikizo zamakina owongolera.
2.Zofunikira zolondola komanso zolondola
Popanga ma implants a thupi monga kulowetsa m'chiuno ndi mawondo, kulondola kwambiri ndi kulondola kumafunika.Izi zili choncho chifukwa ngakhale zolakwika zazing'ono zamakina zimatha kukhudza kwambiri moyo ndi thanzi la wodwala.Malo opangira makina a CNC amatha kupanga molondola magawo omwe amakwaniritsa zosowa za wodwala kudzera mumitundu ya CAD ndikusintha ukadaulo waukadaulo potengera zofunikira za maopaleshoni a mafupa, kukwaniritsa zololera zazing'ono ngati 4 μm.
Zida wamba za CNC zitha kukhala zovuta kukwaniritsa zofunikira potsata kulondola, kukhazikika komanso kuwongolera kugwedezeka.Kukula kwa tizigawo ting'onoting'ono nthawi zambiri kumakhala pamlingo wa micron, womwe umafunikira zida zokhala ndi malo obwerezabwereza komanso kuwongolera koyenda.Pokonza tizigawo ting'onoting'ono, kugwedezeka pang'ono kungayambitse kutsika kwapamwamba komanso miyeso yolakwika.CNC processing wa zigawo zing'onozing'ono zipangizo zachipatala amafuna kusankha CNC makina zida ndi kusamvana mkulu ndi mkulu-mwatsatanetsatane kachitidwe kuwongolera ndemanga, monga makina asanu olamulira zida, amene amagwiritsa ntchito spindles mkulu-liwiro ndi levitation mpweya kapena maginito levitation luso kuchepetsa mikangano ndi kugwedera.
3.Zovuta zakuthupi
Makampani azachipatala amafunikira ma implants kuti apangidwe ndi zinthu zomwe zimagwirizana ndi biocompatible monga PEEK ndi titaniyamu alloys.Zidazi zimakonda kutulutsa kutentha kwambiri panthawi yokonza, ndipo kugwiritsa ntchito zoziziritsa kukhosi nthawi zambiri sikuloledwa chifukwa chodera nkhawa za kuipitsidwa.Zida zamakina a CNC ziyenera kugwirizana ndi zida zosiyanasiyana kuti zithandizire zinthu zovutazi, komanso kuwongolera bwino kutentha ndikupewa kuipitsidwa pakupanga makina.
Makina a CNC azigawo zing'onozing'ono za chipangizo chachipatala amafuna kufufuza ndikumvetsetsa zazinthu zosiyanasiyana zamagulu azachipatala, kuphatikiza zitsulo, mapulasitiki ndi zoumba, komanso momwe amagwirira ntchito pamakina a CNC.Khazikitsani njira zamakina zomwe mukufuna komanso magawo, monga kuthamanga koyenera, kuchuluka kwa chakudya ndi njira zoziziritsira, kuti zigwirizane ndi zosowa za zida zosiyanasiyana.
4.Tool wear and error control
Pamene CNC ikonza tizigawo ting'onoting'ono, kuvala kwa zida kumakhudza kwambiri khalidwe la processing.Choncho, zipangizo zamakono zamakono ndi matekinoloje okutira, komanso kuwongolera zolakwika ndi ukadaulo woyezera, zimafunikira kuti zitsimikizire zolondola panthawi ya makina ndi kulimba kwa zida.Kugwiritsa ntchito zida zopangidwa mwapadera monga cubic boron nitride (CBN) ndi polycrystalline diamondi (PCD), komanso njira zoziziritsa bwino komanso zopaka mafuta, zimatha kuchepetsa kutentha komanso kuvala kwa zida.
Makina a CNC azigawo zing'onozing'ono zachipatala amasankha ndikugwiritsa ntchito zodulira zazing'ono ndi zowongolera zolongosoka zomwe zidapangidwa kuti zizitha kukonza tizigawo ting'onoting'ono.Kuyambitsa dongosolo losinthika lamutu kuti ligwirizane ndi zosowa zosiyanasiyana zogwirira ntchito, kuchepetsa nthawi yosinthira zida ndikuwongolera kusinthasintha kwa kukonza.
5.Process parameter kukhathamiritsa
Pofuna kukonza khalidwe processing ndi dzuwa la tinthu tating'ono, m'pofunika konza magawo ndondomeko, monga kudula liwiro, chakudya liwiro ndi kudula kuya.Magawo awa amakhudza mwachindunji mawonekedwe opangidwa ndi makina komanso kulondola kwake:
1. Kudula liwiro: Kuthamanga kwambiri kungayambitse kutenthedwa kwa chida ndikuwonjezera kuvala, pomwe liwiro lotsika kwambiri limachepetsa kukonza bwino.
2. Kuthamanga kwa chakudya: Ngati liwiro la chakudya ndilokwera kwambiri, zingayambitse kutsekeka kwa chip ndi kupukuta pamwamba.Ngati liwiro la chakudya ndilotsika kwambiri, lidzakhudza momwe ntchitoyo ikuyendera.
3. Kudula kwakuya: Kudula kwambiri kudzawonjezera katundu wa zida, zomwe zimapangitsa kuti zida ziwonongeke komanso zolakwika za makina.
Kukhathamiritsa kwa magawowa kuyenera kutengera momwe zinthu ziliri komanso momwe zida zogwirira ntchito zimagwirira ntchito.The ndondomeko magawo akhoza wokometsedwa kudzera zoyeserera ndi kayeseleledwe kupeza bwino kudula zinthu.
6.Kuwongolera zolakwika ndi kuyeza
Miyeso yazigawo zing'onozing'ono zachipatala ndizochepa kwambiri, ndipo njira zoyezera zachikhalidwe sizingakwaniritse zofunikira.Zida zoyezera zowoneka bwino kwambiri komanso makina oyezera (CMM) amafunikira kuti awonetsetse kuti ntchitoyo ndi yabwino.Zotsutsana nazo zimaphatikizapo kuyang'anira nthawi yeniyeni ndi kubwezera zolakwa panthawi yokonza, kugwiritsa ntchito zipangizo zoyezera bwino kwambiri poyang'ana workpiece, ndi kusanthula zolakwika zofunikira ndi malipiro.Panthawi imodzimodziyo, ndondomeko yoyendetsera ndondomeko (SPC) ndi njira zina zoyendetsera khalidwe ziyenera kukhazikitsidwa kuti zipitirize kuyang'anira ntchito yopanga ndikupanga kusintha kwanthawi yake.
GPM imayang'ana kwambiri ntchito za CNC zopangira zida zachipatala zolondola.Zabweretsa pamodzi zida zopangira zida zamakono komanso magulu aukadaulo.Yadutsa chiphaso cha ISO13485 pazida zamankhwala kuti iwonetsetse kuti imapereka zinthu ndi ntchito zabwino kwambiri kwa kasitomala aliyense ndipo yadzipereka kupatsa makasitomala zinthu zabwino kwambiri.
