CNC Machining Ntchito Chitetezo
Zinthu zofunika kuziganizira panthawi yokonza zolakwika
1) Sinthani, sinthani ndikusintha pulogalamuyo. Ngati ndi gawo loyamba lodulidwa, liyenera kukhala lowuma kuti liwonetsetse kuti pulogalamuyo ndi yolondola.
2) Ikani ndikusintha chosinthacho molingana ndi zofunikira za ndondomekoyi, ndikuchotsani zitsulo ndi zinyalala pamalo aliwonse oyimilira.
3) Gwirani chogwirira ntchito molingana ndi zofunikira zoyikira kuti muwonetsetse kuti pali malo oyenera komanso odalirika. Osamasula workpiece panthawi yokonza.
4) Ikani chida chomwe chidzagwiritsidwe ntchito. Ngati ndi malo opangira makina, nambala ya malo a chida pa magazini ya chida iyenera kukhala yogwirizana ndi nambala yachida yomwe ili mu pulogalamuyi.
5) Chitani zoikamo zida molingana ndi chiyambi chokhazikitsidwa pa workpiece kuti mukhazikitse dongosolo lolumikizirana. Ngati zida zambiri zikugwiritsidwa ntchito, zida zotsalirazo zidzalipidwa kutalika kapena nsonga motsatana.
Zida zamakina zoyendetsedwa ndi manambala zimagwiritsidwa ntchito kwambiri pakukonza makina chifukwa cha kulondola kwambiri, kuchita bwino kwambiri, komanso kusinthika kwamagulu ang'onoang'ono amitundu ingapo yamagawo ovuta. Mwachidule, processing wa CNC makina zida ali ubwino zotsatirazi.
(1) Kutha kusintha. Kusinthasintha ndizomwe zimatchedwa kusinthasintha, ndiko kusinthasintha kwa chida cha makina olamulidwa ndi index kuti chisinthe ndi kusintha kwa chinthu chopanga. Mukasintha magawo a makina pa chida cha makina a CNC, mumangofunika kukonzanso pulogalamuyo ndikulowetsa pulogalamu yatsopano kuti muzindikire kukonza kwa gawo latsopano; palibe chifukwa chosinthira hardware ya gawo lamakina ndi gawo lowongolera, ndipo njira yopangira imatsirizika yokha. Izi zimapereka mwayi waukulu pakupanga gulu limodzi, laling'ono laling'ono komanso kupanga mayeso azinthu zatsopano zamagawo ovuta. Kusinthasintha kwamphamvu ndi mwayi wodziwika kwambiri wa zida zamakina a CNC, komanso chifukwa chachikulu chopangira ndikukula mwachangu zida zamakina a CNC.
(2) Zolondola kwambiri komanso zokhazikika. Zida zamakina a CNC zimakonzedwa motsatira malangizo operekedwa mu mawonekedwe a digito. Muzochitika zodziwika bwino, ntchitoyo sifunikira kulowererapo pamanja, zomwe zimachotsa cholakwika chomwe chimachitika ndi wogwiritsa ntchito. Popanga ndi kupanga zida zamakina a CNC, njira zambiri zatengedwa kuti gawo lamakina la zida zamakina a CNC lifike pamlingo wapamwamba komanso wokhazikika. Kuyenda kofanana ndi matabuleti a zida zamakina a CNC nthawi zambiri kumafika 0.01 ~ 0.0001mm, ndipo kubwereranso kwa unyolo wopatsira chakudya ndi cholakwika cha phula lowongolera zitha kulipidwa ndi chipangizo cha CNC. Chida cha makina a CNC chapamwamba kwambiri chimatengera wolamulira wa grating kuti aziwongolera zotsekeka za kayendetsedwe ka ntchito. Kulondola kwa makina kwa zida zamakina a CNC kwawonjezeka kuchoka pa ± 0.01 mm m'mbuyomu mpaka ± 0.005 mm kapena kupitilira apo. Kulondola kwa malo kwafika ± 0.002mm～± 0.005mm koyambirira ndi pakati pa zaka za m'ma 1990.
Komanso, dongosolo kufala ndi dongosolo CNC makina chida ali olimba mkulu ndi matenthedwe bata. Kudzera luso chipukuta misozi, CNC makina zida angapeze apamwamba processing olondola kuposa awo. Makamaka, kusasinthika kwa kupanga gawo lomwelo la magawo kumakhala bwino, kuchuluka kwa ziyeneretso za mankhwalawa ndikwambiri, ndipo kuwongolera kumakhala kokhazikika.
(3) Kuchita bwino kwambiri. Nthawi yofunikira pakukonza magawo makamaka imaphatikizapo magawo awiri: nthawi yoyendetsa ndi nthawi yothandizira. Kuthamanga kwa spindle ndi kuchuluka kwa chakudya cha chida cha makina a CNC kumakhala ndi kusiyana kwakukulu kuposa zida zamakina wamba. Choncho, ndondomeko iliyonse ya CNC makina chida akhoza kusankha yabwino kudula kuchuluka. Chifukwa cha kukhwima kwa CNC makina chida dongosolo, amalola kudula wamphamvu ndi kuchuluka kwa kudula, amene bwino kudula dzuwa la CNC makina chida ndi kupulumutsa nthawi kuwongolera. Magawo osunthika a chida chowongolera manambala amakhala ndi liwiro lothamanga lopanda ntchito, nthawi yayifupi yolumikizira, ndipo chida chimatha kusinthidwa, ndipo nthawi yothandizira imachepetsedwa kwambiri poyerekeza ndi zida zamakina wamba.
