Malizitsani Makina a Cmm ndi Kuyeserera

Kodi makina a cmm ndi ati?

TAYEREKEZANI ZINSINSI ZOTHANDIZA CNC Ndi zomwe mapanga a CMM amatero!

Cmm imayimira "makina oyezera makina". Mwinanso ndi zida zokwanira 3D zoyezera malinga ndi kuphatikiza kwawo kosasinthika, kulondola, komanso kuthamanga.

Ntchito Zowongolera Makina Oyezera

Cowirira makina oyezera ndiofunika nthawi iliyonse molondola mufunika kupangidwa. Ndi zovuta kwambiri kapena kuchuluka kwake, kuchuluka kwa mankhwalawa.

Nthawi zambiri cmm amagwiritsidwa ntchito poyang'ana komanso kuwongolera. Ndiye kuti, amagwiritsidwa ntchito kutsimikizira gawoli likukumana ndi zomwe wopanga amafuna ndi zokambirana.

Atha kugwiritsidwa ntchitoSinthani injinimagawo omwe alipo popanga zolondola za mawonekedwe awo.

Ndani adapanga makina ammm?

Makina oyamba a cmm adapangidwa ndi kampani ya Ferria ya Scotland m'ma 1950. Anafunikira pakuyeneretsa magawo a zigawo mu Aerosseace ndi chitetezo. Makina oyamba okhawo anali ndi ma axel awiri oyenda. Makina atatu a Axis adayambitsidwa m'ma 1960 ndi dena ya Italy. Kuwongolera kwamakompyuta kunabwera kumayambiriro kwa zaka za m'ma 1970, ndipo kunayambitsidwa ndi Sheffield ku USA.

Mitundu ya Makina a Cmm

Pali mitundu isanu ya mgwirizano woyenerera:

• Bridge mtundu Cmm: Mu kapangidwe kameneka, chofala kwambiri, cha cmm mutu pa mlatho. Mbali imodzi ya mlatho umakwera panjira pa kama, ndipo inayo imathandizidwa pa khutu la mpweya kapena njira ina pabedi popanda njanji yowongolera.
• CAntmver Cmm: Chingwe chimathandizira mlatho umodzi mbali imodzi yokha.
• Gantry Cmm: The Gantry amagwiritsa ntchito njanji yowongolera mbali zonse ziwiri, ngati rauta ya cnc. Izi ndizachilendo chachikulu kwambiri cmm, chifukwa chake amafunikira thandizo lowonjezera.
• Kuzungulira kwa mtsinje wa mgm: chithunzi, koma ndi mlatho wonse ukusunthira mmwamba ndi pansi mkono umodzi m'malo pachimodzi. Awa ndi mgmumba wocheperako, koma amatha kuyeza zowonda kwambiri ndi zinthu zina monga matupi auto.
• Khoma Loipa la Cmm: Makinawa amagwiritsa ntchito mikono yolumikizirana ndipo nthawi zambiri amakhala omasuka. M'malo moyeza xyz mwachindunji, amawerengera zogwirizana ndi malo olumikizirana ndi kutalika komwe kumalumikizana ndi mafupa.

Aliyense ali ndi zabwino ndi zovuta kutengera mitundu ya miyeso yomwe ingapangidwe. Mitundu iyi imatchula kapangidwe ka makina omwe amagwiritsidwa ntchitolowewachibale mpaka kuyesedwa.

Nayi tebulo lamanja kuti muthandizire kumvetsetsa zabwino ndi zolemetsa:

Zolemba nthawi zambiri zimakhazikika mumiyeso zitatu-x, z, ndi z. Komabe, makina apamwamba kwambiri amathanso kulola kuti makona asinthidwa kuti asinthidwe ku malo omwe akupezeka kuti akwaniritse. Ma tebulo ozungulira atha kugwiritsidwanso ntchito kukonza njira zosiyanasiyana.

Cmm nthawi zambiri zimapangidwa ndi granite ndi aluminiyamu, ndipo amagwiritsa ntchito magetsi

Probe ndi sensor yomwe imatsimikiza komwe kuli gawo ndi pomwe muyeso umapangidwa.

Mitundu ya probe ikuphatikiza:

• Zazitsulo
• Zamaso
• Laser
• Kuwala koyera

Makina ogwirizanitsa amagwiritsidwa ntchito m'njira zitatu zonse:

• Madipatimenti Olamulira: Pano pali nthawi zambiri amasungidwa mchipinda chovomerezeka cham'dziko kuti apititse patsogolo.
• Malo ogulitsira: Apa Cmm ali pansi pamakina a CNC kuti ikhale yosavuta kugwira ntchito ngati gawo lokhala ndi mayendedwe ochepera pakati pa cmm ndi makina omwe magawo akupangidwa. Izi zimathandiza kuti mupange zomwe zimapangidwa kale ndipo zomwe mwina ndizomwe zimayambitsa kupulumutsa monga zolakwika zimadziwika posachedwa.
• Cholinga: Zonyamula CMM ndizosavuta kuyendayenda. Atha kugwiritsidwa ntchito pansi pa shopu kapena kumapita kumalo akutali kuchokera ku malo opangira kuti ayesere magawo.

Kodi makeke a cmm (cmm) ndi olondola bwanji)?

Kulondola kwa makina ogwirizanitsa amasiyanasiyana. Nthawi zambiri, akufuna kuwongolera micrometer kapena bwino. Koma sizovuta. Chifukwa chimodzi, pali cholakwika cha kukula, kotero cholakwika cha cmm chimatha kufotokozedwa ngati njira yayifupi yomwe imaphatikizapo kutalika kwa muyeso wa muyeso monga chosinthika.

Mwachitsanzo, dziko la Hexaloan Clearlic Cmm limalembedwa kuti ndi Cmm yotsika mtengo kwambiri, ndipo imafotokoza molondola kwambiri monga:

1.0 + L / 300um

Miyeso yomwe ili mu microns ndipo l yafotokozedwa mu mm. Chifukwa chake tinene kuti tikuyesa kuyeza kutalika kwa gawo la 10mmmmm. Njira yake ingakhale 1.0 + 10/300 = 1.0 + 1/30 kapena 1.03 mic.

Micron ndi chikwi cha mm, omwe ali pafupifupi 0,00003937 mainchesi. Chifukwa chake cholakwika pakuyeza kutalika kwa 10mmm ndi 0,00103 mm kapena 0,00004055 mainchesi. Ndizocheperapo kuposa theka la chovuta chaching'ono!

Kumbali ina, munthu ayenera kukhala wolondola 10x zomwe tikufuna kudziwa. Chifukwa chake zikutanthauza kuti tingokhulupirira izi kwa 10x mtengo womwewo, kapena mainchesi 0,0055. Kulakwitsa kakang'ono kwambiri.

Zinthu zimatenga ngakhale kung'ung'udza kwa malo ogulitsira ma shopu. Ngati cmm imakhazikitsidwa ndi labu yoyang'aniridwa, imathandizira kwambiri. Koma pa malo ogulitsira, kutentha kumatha kusintha kwambiri. Pali njira zosiyanasiyana cmm amatha kulipirira mitundu yosiyanasiyana ya kutentha, koma palibe wangwiro.

Opanga cmm nthawi zambiri amatanthauza kulondola kwa gulu la kutentha, komanso malinga ndi iso 7360-2 Standal ya CM Scorestract Colountri, gulu wamba ndi 64-2C). Izi ndi zabwino pokhapokha malo ogulitsira anu ndi 86f m'chilimwe. Ndiye mulibe mtundu wabwino wolakwitsa.

Opanga ena amakupatsani mwayi wokhala ndi masitepe a masitepe kapena matenthedwe otenthetsera osiyana ndi olondola. Koma chimachitika ndi chiani ngati muli ndi gawo limodzi lofanana ndi zomwezo nthawi zina masana kapena masiku osiyanasiyana a sabata?

Wina amayamba kupanga bajeti yosatsimikizika yomwe imalola milandu yoyipitsitsa. Ngati milandu yoyipayi imapangitsa kuti zisakhale zolephera pazigawo zanu, kusintha kwinanso kukufunika:

• Mutha kuchepetsa kugwiritsidwa ntchito kwa cmm ku nthawi zina ma tempi akagwera m'magawo abwino kwambiri.
• Mutha kusankha kumakina okhawo ochepetsa magawo kapena mawonekedwe nthawi zina.
• Zabwino za CMM zitha kukhala ndi zokongoletsera zabwino kwa kutentha kwanu kumalowa. Amatha kukhala ofunika ngakhale atha kukhala okwera mtengo kwambiri.

Zachidziwikire kuti njirazi zimatha kuwononga luso lanu kuti musinthe ntchito zanu. Mwadzidzidzi mukuganiza kuti malo abwino a malo ogulitsira akhoza kukhala ofunika kwambiri.

Mutha kuwona momwe muyeso wonsewu umakhalira wopanda nzeru.

Zosakaniza zina zomwe zimapita m'manja ndi momwe kulekeredwe ndi cmm kumatchulidwa. Muyezo wa golide ndi geometric kukula ndi kulolera (GD & T). Onani maphunziro athu oyambira pa GD & T kuti mudziwe zambiri.

Cmm

CMM imayendetsa mitundu mitundu ya mapulogalamu. Mkhalidwewu umatchedwa DMIS, yomwe imayimira mawonekedwe amtundu wa mawonekedwe. Ngakhale siyimodzi pulogalamu yamapulogalamu ya CM aliyense wopanga, ambiri aiwo samachirikiza.

Opanga apanga zovala zawo zapadera kuti awonjezere ntchito zomwe sizikugwirizana ndi DMIS.

Dis

Monga tatchulira DMIS, ndiye muyeso, koma monga GZC's G-Code, pali zilankhulo zambiri kuphatikiza:

• PC-DMIS: Version's Version
• Otsegula
• HATDMIS: Percetron

Mcososmos

Mcystmos ndi pulogalamu ya Nikon.

Calypso

Calypso ndi pulogalamu ya Cmm kuchokera ku Mosem.

CMM ndi CAD / Cam Mapulogalamu

Kodi Cmm Pulogalamu ya Cmm ndi fomu ikukhudzana bwanji ndi CAD / Cam?

Pali mafayilo ambiri a CAD, kotero onani omwe mapulogalamu anu a Cmm amagwirizana nayo. Kuphatikiza kwakukulu kumatchedwa kuti tanthauzo la zithunzi (MBD). Ndili ndi MBD, mtundu womwewo umatha kugwiritsidwa ntchito pochotsa miyeso ya cmm.

MDB ndi yokongola yotsogola, kotero sizikugwiritsidwa ntchito pazovuta zambiri.

CMM Melose, Fixtaxal, ndi Zachilengedwe

Cmm

Mitundu yosiyanasiyana ya probe ndi mawonekedwe amapezeka kuti ithandizire mapulogalamu ambiri.

Mim Fixtations

Zosintha zonse ndikusunga nthawi yosungirako ndikutsitsa magawo pa cmm, monga ngati makina a CNC. Muthanso kupeza ma cmm omwe ali ndi mwayi wokhathamiritsa kuti achuluke.

Mtengo wa Cmm

Makina atsopano oyezera amayamba $ 20,000 mpaka $ 30,000 ndikupita mpaka $ 1 miliyoni.

Ntchito zokhudzana ndi CMMM mu shopu yamakina
