CNC Machining Sarudza Kucheka Mari
MuNC programming, mugadziri anofanirwa kuona huwandu hwekucheka kwega rega rega onyora muchirongwa nenzira yemirairo. Kucheka maparamendi anosanganisira kumhanya kwespindle, kumashure-kucheka huwandu uye kumhanya kwekudya. Kune nzira dzakasiyana dzekugadzirisa, dzakasiyana siyana dzekucheka paramita dzinoda kusarudzwa. Nheyo yekusarudza yehuwandu hwekucheka ndeyekuona machining echokwadi uye kushata kwepamusoro kwezvikamu, kupa kutamba kwakazara kukucheka kwechishandiso, kuve nechokwadi chekusimba kwechishandiso, uye kupa kutamba kwakazara kuita kwechishandiso chemuchina kuti uwedzere kubereka. uye kuderedza mari.
1. Sarudza Spindle Speed
Iyo spindle yekumhanyisa inofanirwa kusarudzwa zvinoenderana neinobvumidzwa yekucheka kumhanya uye dhayamita yeworkpiece (kana chishandiso). Iyo yekuverenga formula ndeye: n=1000 v/7 1D kupi: v? kucheka kumhanya, iyo unit ndeye m / m kufamba, iyo inotarirwa nekugara kwechishandiso; n is the spindle speed, unit is r/min, uye D ndiyo dhayamita yeworkpiece Kana mudziyo dhayamita, mumm. Kune yakaverengerwa spindle kumhanya n, kumhanya uko muchina mudziyo une kana kuti uri padyo unofanirwa kusarudzwa kumagumo.
2. Sarudza Mutengo Wekudya
Kumhanyisa kwekudya ndiyo yakakosha parameter mukucheka maparamendi eCNC muchina maturusi, ayo anonyanya kusarudzwa zvinoenderana nekurongeka kwemachini uye kushata kwepamusoro zvinodiwa zvezvikamu uye zvinhu zvekushandisa zvezvishandiso uye workpieces. Iyo yakawanda yekudyisa chiyero inogumira nekuomarara kwechishandiso chemuchina uye kushanda kweiyo feed system. Nheyo yekuona chiyero chekudya: Kana iyo yemhando yezvinodiwa yeworkpiece inogona kuvimbiswa, kuitira kuti uvandudze kushanda kwekugadzira, chiyero chepamusoro chekudya chinogona kusarudzwa. Kazhinji inosarudzwa muhuwandu hwe100-200mm / min; kana uchicheka, uchigadzira maburi akadzika kana kugadzirisa ne-high-speed simbi maturusi, zvinokurudzirwa kusarudza yakaderera feed speed, inowanzosarudzwa muhuwandu hwe20-50mm / min; apo kururamisa kwekugadzirisa, iyo yepamusoro Kana iyo roughness inotarisirwa yakakwirira, kukurumidza kwekudya kunofanira kusarudzwa kuduku, kazhinji muhuwandu hwe20-50mm / min; kana chishandiso chisina chinhu, kunyanya kana chinhambwe chakareba "chidzokera ku zero", unogona kuseta iyo CNC system marongero emuchina chishandiso Chiyero chepamusoro chekudya.
3. Sarudza kuwanda kweZvishandiso zveKumashure
Kuwanda kwekudzokera shure kunotarirwa nekuoma kwechigadzirwa chemuchina, workpiece uye kucheka. Kana iyo rigidity ichibvumira, huwandu hwekudzokera shure hunofanira kuenzana nemvumo yekugadzira yeworkpiece zvakanyanya sezvinobvira, izvo zvinogona kuderedza nhamba yekupfuura uye kuvandudza kugadzirwa kwekugadzira. Kuti uve nechokwadi chemhando yepasi yakagadzirwa, shoma shoma yekupedzisa mvumo inogona kusiiwa, kazhinji 0.2-0.5mm. Muchidimbu, kukosha kwakananga kwehuwandu hwekucheka hunofanira kutsanangurwa nekuenzanisa zvichienderana nekushanda kwechishandiso chemuchina, mabhuku ane hukama uye ruzivo chairwo.
Panguva imwecheteyo, iyo spindle kumhanya, kucheka kudzika uye kukurumidza kwekudya kunogona kuchinjirwa kune mumwe nemumwe kuti iite yakanakisa yekucheka huwandu.
Huwandu hwekucheka hausi chete hwakakosha paramende iyo inofanirwa kutariswa isati yagadziriswa muchina, asi zvakare kana kukosha kwayo kwakakodzera kana kusave nepesvedzero yakakosha pamhando yekugadzira, kushanda zvakanaka, uye mutengo wekugadzira. Iyo inonzi "inonzwisisika" yekucheka huwandu hunoreva huwandu hwekucheka hunoshandisa zvizere kuita kwekucheka kwechishandiso uye kushanda nesimba (simba, torque) yemuchina wemuchina kuwana kugadzirwa kwakanyanya uye yakaderera mutengo wekugadzirisa pasi pechisimbiso che. kuve nechokwadi chemhando.
Iyo muromo werudzi urwu rwekushandura chishandiso inoumbwa nemitsetse mikuru uye yechipiri yekucheka micheto, senge 900 yemukati nekunze maturusi ekutendeuka, kuruboshwe uye kurudyi kumagumo kumeso ekutenderedza maturusi, grooving (kucheka) maturusi ekushandura, uye akasiyana ekunze uye emukati ekucheka maturusi ane. diki tip chamfers. Gomba rinotenderedza mudziyo. Iyo nzira yekusarudza yejometri paramita yechishandiso chakanongedza chekushandura (kunyanya iyo geometric angle) yakangofanana neyakajairika kutendeuka, asi hunhu hweCNC machining (senge nzira yekugadzira, kupindira kwemuchina, nezvimwewo) inofanirwa kutariswa zvizere. , uye tepi yekushandisa pachayo inofanira kutorwa sesimba.
