Izinyathelo ezi-7 zokusebenzisa isikhungo semishini ye-CNC

1. Ukulungiselela ukuqalisa

 

Ngemva kokuqaliswa ngakunye noma ukumisa kabusha okuphuthumayo kwethuluzi lomshini, qala ngokubuyela endaweni eyireferensi enguziro yethuluzi lomshini (okungukuthi buyela kuqanda), ukuze ithuluzi lomshini libe nendawo eyinkomba ekusebenzeni kwalo okulandelayo.

 

2. I-clamping workpiece

 

Ngaphambi kokuba i-workpiece iboshwe, izindawo ezingaphezulu kufanele zihlanzwe kuqala, ngaphandle kokungcola kwamafutha, ama-chips ensimbi nothuli, futhi ama-burrs endaweni yokusebenza kufanele asuswe ngefayela (noma i-oilstone).cnc machining ingxenye

 

Isitimela esinesivinini esikhulu sokubopha kufanele sibe phansi bushelelezi futhi sicaba ngomshini wokugaya.I-block iron namantongomane kufanele aqine futhi akwazi ukubopha ucezu lokusebenzela ngokuthembekile.Kwamanye ama-workpiece amancane okunzima ukuwacindezela, angaboshelwa ngqo kwingwe.Ithebula elisebenzayo lethuluzi lomshini kufanele lihlanzeke futhi lingabi nama-chips ensimbi, uthuli namabala kawoyela.I-pad iron ngokuvamile ibekwa emagumbini amane omsebenzi wokusebenza.Ukuze uthole ama-workpieces ane-span enkulu kakhulu, kuyadingeka ukwengeza insimbi ephezulu ye-pad phakathi.cnc ingxenye yokugaya

 

Hlola ukuthi ubude, ububanzi nobude bezinto zokusebenza zifanelekile yini ngokusebenzisa umthetho wokudonsa ngokuvumelana nobukhulu bomdwebo.

 

Lapho ucindezela i-workpiece, ngokuya nge-clamping kanye nemodi yokubeka yomyalelo wokusebenza kwezinhlelo, kuyadingeka ukucabangela ukugwema izingxenye zokucubungula kanye nesimo lapho ikhanda lokusika lingase lihlangabezane ne-clamp ngesikhathi sokucubungula.cnc omshini

 

Ngemuva kokuthi i-workpiece ibekwe kubhlokhi yokulinganisa, indawo yereferensi ye-workpiece izodonswa ngokuvumelana nezidingo zomdwebo, futhi i-perpendicularity ye-workpiece egayiwe ezinhlangothini eziyisithupha izobhekwa ukuze kubonakale ukuthi ifanelekile yini.

 

Ngemva kokuphothulwa komdwebo womsebenzi, i-nati kufanele iqiniswe ukuze ivimbele umsebenzi-ukusebenza ekushintsheni ngesikhathi sokucubungula ngenxa yokugoqa okungavikelekile;donsa ucezu lomsebenzi futhi ukuze uqiniseke ukuthi iphutha alikho ngaphezu kwephutha ngemuva kokubopha.

 

3. Inombolo yokushayisana yama-workpieces

 

Ocwecweni lokusebenza oluboshiwe, inani lamaqhuqhuva lingasetshenziswa ukunquma indawo eyireferensi enguziro yomshini, futhi inani lamaqhuqhuva kungaba ngugesi wesithombe noma owomshini.Kunezinhlobo ezimbili zezindlela: inombolo yokushayisana okuphakathi kanye nenombolo yokushayisana okukodwa.Izinyathelo zenombolo yokushayisana emaphakathi zimi kanje:

 

I-Photoelectric static, isivinini somshini 450 ~ 600rpm.Hambisa ngokuzenzela i-x-eksisi yethebula lokusebenza ukuze wenze ikhanda elishayisanayo lithinte uhlangothi olulodwa lomsebenzi.Uma ikhanda elishayisanayo lithinta nje ucezu lokusebenza futhi ukukhanya okubomvu kuvuliwe, setha inani elihlobene lokuxhumanisa leli phuzu libe nguziro.Bese uhambisa ngokuzenzela i-x-eksisi yethebula lokusebenza ukuze wenze ikhanda elishayisanayo lithinte kolunye uhlangothi lomsebenzi.Lapho ikhanda elishayisanayo lithinta nje ucezu lokusebenza, rekhoda isixhumanisi esihlobene ngalesi sikhathi.

 

Ngokwevelu ehlobene susa ububanzi bekhanda lokushayisana (okungukuthi ubude bocezu lokusebenza), hlola ukuthi ubude bocwecwe lokusebenza luyahlangabezana yini nezimfuneko zomdwebo.

 

Hlukanisa le nombolo yokuxhumanisa isihlobo ngo-2, futhi inani eliwumphumela liyinani eliphakathi le-eksisi engu-x yocezu lokusebenza.Bese uhambisa ithebula lokusebenzela enanini eliphakathi le-eksisi ka-x, bese usetha inani lokuxhumanisa elihlobene lale eksisi engu-X liye kuziro, okuyindawo eyiziro ye-eksisi ka-x yomsebenzi.

 

Rekhoda ngokucophelela inani lokudidiyela lomshini lendawo enguziro ku-axis engu-x yocezu lokusebenza kwenye ye-G54-G59, futhi uvumele ithuluzi lomshini linqume indawo eyiziro ku-eksisi engu-x yocezu lokusebenza.Hlola ukulunga kwedatha ngokucophelela futhi.Inqubo yokusetha indawo enguziro ye-eksisi ye-Y yocezu lokusebenza iyafana naleyo ka-x-eksisi.

 

4. Lungiselela wonke amathuluzi ngokomyalelo wokusebenza kohlelo

 

Ngokwedatha yethuluzi emyalelweni wokusebenza kohlelo, buyisela ithuluzi elizocutshungulwa, vumela ithuluzi lithinte idivayisi yokulinganisa ubude ebekwe endizeni eyireferensi, futhi usethe inani elihlobene lokudidiyela leli phuzu libe uziro lapho ukukhanya okubomvu kokulinganisa. idivayisi ivuliwe.Umagazini we-Mold Man sixoxa kahle, kufanele ukunakwa!Hambisa ithuluzi endaweni ephephile, hambisa ithuluzi mathupha ngo-50mm, bese usetha inani elihlobene lokuxhumanisa laleli phuzu liye kuziro futhi, okuyiziro ukuma kwe-eksisi engu-Z.

 

Rekhoda ivelu ye-mechanical coordinate Z yaleli phoyinti kwenye ye-G54-G59.Lokhu kuqeda ukulungiselelwa kukaziro kwama-eksisi angu-X, y kanye no-Z ocezu lokusebenza.Hlola ukulunga kwedatha ngokucophelela futhi.

 

Inombolo yohlangothi olulodwa yokushayisana iphinde ithinte uhlangothi olulodwa lwe-eksisi engu-x kanye ne-Y-eksisi yomsebenzi ngokwendlela engenhla.Hlukanisa inani elihlobene lokuxhumanisa le-eksisi engu-x kanye ne-eksisi engu-Y yaleli phuzu kurediyasi yenhloko yenombolo yokushayisana, okuyisimo esinguziro se-eksisi ka-x kanye ne-eksisi ka-y.Okokugcina, rekhoda izixhumanisi zomshini ze-x-eksisi kanye ne-Y-eksisi yephoyinti kwenye ye-G54-G59.Hlola ukulunga kwedatha ngokucophelela futhi.

 

Hlola ukunemba kwephoyinti elinguziro, hambisa izimbazo zika-X kanye no-Y ekumisweni okuseceleni kwendawo yokusebenza, bese ubheka ngokubukeka ukulunga kwephuzu elinguziro ngokobukhulu bomsebenzi wokusebenza.

 

Kopisha ifayela lohlelo kukhompuyutha ngokuya ngendlela yefayela yomyalelo wokusebenza wohlelo.

 

5. Ukusetha imingcele yokucubungula

 

Ukusetha isivinini sokuphotha emishinini: n = 1000 × V / (3.14 × d)

 

N: isivinini sokuphotha (RPM / iminithi)

 

V: isivinini sokusika (M / min)

 

D: Ububanzi bethuluzi (mm)

 

Ukulungiselelwa kwesivinini sokuphakelayo komshini: F = n × m × FN

 

F: isivinini sokuphakelayo (mm / min)

 

M: inani lamaphethelo wokusika

 

FN: ukusika inani lethuluzi (mm / inguquko)

 

Ukusika inani lokusetha konqenqema ngalunye: FN = Z × FZ

 

Z: inombolo yezindwani zethuluzi

 

I-FZ: inani elinqunyiwe lomphetho ngamunye wethuluzi (mm / inguquko)

 

6. Qala ukucubungula

 

Ekuqaleni kohlelo ngalunye, kuyadingeka ukuhlola ngokucophelela ukuthi ithuluzi elisetshenzisiwe yilelo elishiwo encwadini yeziqondiso.Ekuqaleni komshini, ijubane lokuphakelayo lizolungiswa libe lincane, futhi lizokwenziwa esigabeni esisodwa.Lapho ibeka, iwisa futhi idla ngokushesha, kufanele igxilwe.Uma kunenkinga ngokhiye wokumisa, yima ngokushesha.Naka ukubuka isiqondiso esinyakazayo somsiki ukuze uqinisekise ukudla okuphephile, bese ukhuphula kancane isivinini sokuphakela ezingeni elifanele.Ngesikhathi esifanayo, engeza umoya opholile noma obandayo kumsiki kanye nomsebenzi.

 

Umshini omangelengele akumele ube kude kakhulu nephaneli yokulawula, futhi umshini uzomiswa ukuze uhlolwe uma kwenzeka kuba khona okungavamile.

 

Ngemuva kokuqina, phinda udonse imitha ukuze uqiniseke ukuthi ucezu lokusebenzela aluxegi.Uma ikhona, kufanele ilinganiswe kabusha futhi ithintwe.

 

Enqubweni yokucubungula, imingcele yokucubungula ihlale ilungiselelwe ukuze kuzuzwe umphumela omuhle kakhulu wokucubungula.

 

Njengoba le nqubo iyinqubo eyinhloko, ngemva kokuba ucezu lokusebenza lucutshunguliwe, inani eliyinhloko lobukhulu lizolinganiswa ukuze kubonakale ukuthi liyahambisana yini nezidingo zomdwebo.Uma kukhona noma iyiphi inkinga, yazisa ngokushesha umholi weqembu noma umhleli osemsebenzini ukuze ayihlole futhi ayixazulule.Ingasuswa ngemva kokuphumelela ukuzihlola, futhi kufanele ithunyelwe kumhloli ukuze ihlolwe ngokukhethekile.

 

Uhlobo lokucutshungulwa: ukucutshungulwa kwembobo: ngaphambi kokubhoboza esikhungweni sokucubungula, indawo yokubhoboza ephakathi kufanele isetshenziselwe ukubeka indawo, bese i-drill bit engu-0.5 ~ 2mm encane kunosayizi womdwebo izosetshenziselwa ukubhola, futhi ekugcineni i-drill bit efanele izosetshenziselwa. ukuqeda.

 

Ukucutshungulwa kwe-Reaming: ukuze uvule kabusha ucezu lokusebenza, qala usebenzise i-drill ephakathi nendawo ukuze uyibeke, bese usebenzisa i-drill bit engu-0.5 ~ 0.3mm encane kunosayizi womdwebo ukuze ubhoboze, futhi ekugcineni usebenzise i-reamer ukuze uvule kabusha imbobo.Naka ukulawula isivinini sokuphotha phakathi kuka-70 ~ 180rpm / min ngesikhathi sokuphinda.

 

Ukucutshungulwa okuyisicefe: ukuze kucutshungulwe ama-workpieces ayisicefe, qala usebenzise i-drill ephakathi nendawo ukuze uthole, bese usebenzisa i-drill bit encane ngo-1-2mm kunosayizi womdwebo ozombayo, bese usebenzisa i-coarse boring cutter (noma i-milling cutter) ukucubungula. ohlangothini lwesokunxele ngesabelo somshini esingaba ngu-0.3mm kuphela, futhi ekugcineni usebenzise isisiki esihle esinesicefe esinosayizi olungisiwe ngaphambili ukuze uqedele isicefe, futhi imvume yokugcina eyisicefe eyisicefe akufanele ibe ngaphansi kuka-0.1mm.

 

Ukusebenza kwezinombolo eziqondile (i-DNC): ngaphambi kokucutshungulwa kokulawulwa kwezinombolo ze-DNC, isiqeshana somsebenzi kufanele siboshwe, indawo ye-zero izosethwa, futhi imingcele izosethwa.Vula uhlelo lokucubungula oluzodluliselwa kukhompuyutha ukuze luhlolwe, bese uvumela ikhompuyutha ukuthi ingene kusimo se-DNC, bese ufaka igama lefayela lohlelo olulungile lokucubungula.Isignali encane ye-Daren: i-mujuren icindezela ukhiye wetheyiphu kanye nokhiye wokuqala wohlelo ethuluzini lomshini, futhi igama elithi LSK likhanya kusilawuli sethuluzi lomshini.Cindezela ikhibhodi yokufaka kukhompuyutha ukucubungula ukudluliswa kwedatha ye-DNC.

 

7. Okuqukethwe kanye nobubanzi bokuzihlola

 

Ngaphambi kokucubungula, umprosesa kufanele abone ngokucacile okuqukethwe kwekhadi lenqubo, azi ngokucacile izingxenye okufanele zicutshungulwe, ubujamo, ubukhulu bemidwebo futhi wazi okuqukethwe kokucubungula kwenqubo elandelayo.

 

Ngaphambi kokubamba i-workpiece, linganisa ukuthi usayizi ongenalutho uyahlangabezana yini nezidingo zomdwebo, futhi uhlole ukuthi ukubekwa kocezu lokusebenza kuyahambisana yini neziqondiso zokusebenza kokuhlela.

 

Ukuzihlola kufanele kwenziwe ngesikhathi ngemuva komshini onzima, ukuze kulungiswe idatha enamaphutha ngesikhathi.Okuqukethwe kokuzihlola ngokuyinhloko isikhundla nosayizi wezingxenye zokucubungula.Isibonelo: noma ngabe i-workpiece ikhululekile;ukuthi i-workpiece ihlukaniswe kahle;noma ngabe ubukhulu obusuka engxenyeni yokucubungula ukuya onqenqemeni lwereferensi (iphoyinti lesithenjwa) liyahlangabezana yini nezidingo zomdwebo;kanye nobukhulu bendawo phakathi kwezingxenye zokucubungula.Ngemva kokuhlola indawo nobukhulu, linganisa irula yomumo womshini omahhadlahhadla (ngaphandle kwe-arc).

 

Ukuqeda imishini kungenziwa kuphela ngemuva komshini onzima nokuzihlola.Ngemva kokuqeda, abasebenzi bazozihlola ngokwabo ukuma nobukhulu bezingxenye ezicutshunguliwe: hlola ubude obuyisisekelo nobubanzi bezingxenye ezicutshunguliwe zendawo eqondile;linganisa usayizi wephuzu eliyisisekelo elimakwe kumdwebo wezingxenye ezicutshunguliwe zendawo ethambekele.

 

Abasebenzi bangasusa ucezu lokusebenza baluthumele kumhloli ukuze luhlolwe ngokukhethekile ngemva kokuqeda ukuzihlola ngokwabo ucezu lokusebenza futhi baqinisekise ukuthi luyahambisana nemidwebo nezidingo zenqubo.
