Isikhungo semishini ye-CNC sidinga ukwenza lezi zinto kahle ekusikeni insimbi

Okokuqala, ukunyakaza okuphendukayo kanye nendawo eyakhiwe

Ukunyakaza kokuguqula: Enqubweni yokusika, i-workpiece kanye nethuluzi kufanele kusikwe ngokuhlobene ukuze kukhishwe insimbi eyengeziwe. Ukunyakaza kwensimbi eyeqile endaweni yokusebenza ngethuluzi elijikayo ku-lathe kubizwa ngokuthi ukunyakaza okuphendukayo, okungahlukaniswa kube ukunyakaza okuyinhloko nokuthuthuka. Zivocavoce.

Ukunyakaza kokuphakelayo: Isendlalelo esisha sokusika siqhubeka sihamba. Ukunyakaza kokuphakelayo ukunyakaza okuhambisana nobuso bomsebenzi ozokwenziwa, okungaba okuqhubekayo noma okuphakathi. Isibonelo, i-lathe evundlile iqhubeka ihamba phakathi nokunyakaza kwethuluzi elijikayo, futhi ukunyakaza kokuphakelayo kocezu lokusebenza kuplanethi yekhanda kuyahamba kancane.

Ingaphezulu elibunjwe ku-workpiece: Ngesikhathi senqubo yokusika, indawo eyenziwe ngomshini, indawo eyenziwe ngomshini, kanye nendawo okumele yenziwe ngomshini kwakhiwa endaweni yokusebenza. Indawo eyenziwe ngomshini yindawo entsha eyakhiwe kusukela ekukhishweni kwensimbi eyeqile. Ingaphezulu elizocutshungulwa libhekisela endaweni lapho ungqimba lwensimbi lusikwa khona. Indawo esebenza ngomshini yindawo lapho unqenqema olujikayo lwethuluzi lokujika luphendulwa khona.Ingxenye yemishini ye-CNC

Ukunyakaza okuyinhloko: nqamula ngokuqondile isendlalelo sokusika ku-workpiece futhi uyiguqule ibe ama-chips, ngaleyo ndlela yakhe ukunyakaza kwendawo entsha ye-workpiece, ebizwa ngokuthi ukunyakaza okuyinhloko. Lapho usika, ukunyakaza okujikelezayo kwe-workpiece kuwukunyakaza okuyinhloko. Ngokuvamile, isivinini sokunyakaza okuyinhloko siphezulu, futhi amandla okusika adliwe abaluleke kakhulu.Ingxenye yokujika ye-CNC

 
Okwesibili, inani lokusika lesikhungo somshini libhekisela ekujuleni kokusika, izinga lokuphakelayo, kanye nesivinini sokusika.

(1) Ukujula kokusika: ap = (dw - dm) / 2 (mm) dw = ububanzi bomsebenzi ongenziwanga dm = ububanzi bomsebenzi owenziwe ngomshini, ukujula kokusika yilokho esivame ukukubiza ngokuthi inani lommese.

Ukukhethwa kokujula kokusika: Ukujula kwe-αp kufanele kunqunywe ngokuya ngesibonelelo somshini. Uma ugoqa, ngaphandle kwesibonelelo esisele, isibonelelo sokubhodla kufanele sinqanyulwe ngangokunokwenzeka. Lokhu akuqinisekisi kuphela umkhiqizo wokusika ukujula, izinga lokuphakelayo ƒ, kanye nesivinini sokusika V esikhulu ngaphansi kwesisekelo sokuqinisekisa izinga elithile lokuqina, kodwa futhi kunganciphisa inani lokudlula, futhi ufune ukufunda uhlelo lokulawula izinombolo lwe-UG ku-QQ. iqembu 304214709 lingathola idatha. Esimeni sokuvunyelwa komshini okweqile, ukuqina okunganele kwesistimu yokucubungula, noma amandla anganele we-blade, kufanele ihlukaniswe ngamaphasi amabili noma ngaphezulu. Ngalesi sikhathi, ukujula kokusika kokudlula kokuqala kufanele kuthathwe kukhudlwana, okungabalelwa ku-2/3 kuya ku-3/4 wesibonelelo esiphelele, futhi ukujula kokusika kwephasi yesibili kufanele kube kuncane ukuze kutholwe inqubo yokuqeda-encane. amavelu wepharamitha yokuqina komhlaba kanye nokunemba okuphezulu komshini.

Uma ingaphezulu lengxenye yokusika linezinto eziqinile ezifana nensimbi, i-forged, noma insimbi engagqwali, ukujula kokusika kufanele kudlule ukuqina noma ungqimba olubandayo ukuze kugwenywe ukusika umkhawulo wokusika ongqimbeni oluyinkinga noma olubandayo.

(2) Ukukhethwa kwenani lokuphakelayo: ukugudluzwa okuhlobene kwendawo yokusebenza kanye nethuluzi eliqondiswe lapho ukunyakaza kokuphakelayo, ngamayunithi angama-mm ngokuphenduka ngakunye noma ukuphindaphinda kwesiqephu sokusebenza noma ithuluzi. Ngemuva kokuthi kukhethiwe ukujula kokusika, izinga lokuphakelayo elibaluleke kakhulu kufanele likhethwe ngangokunokwenzeka. Inani elifanelekile lesilinganiso sokuphakela kufanele liqinisekise ukuthi umshini kanye nethuluzi akulimazwa amandla amaningi okusika. Ukuchezuka kocezu lokusebenza okubangelwa amandla okusika akudluli inani elivumelekile lokunemba kocezu lokusebenza, futhi inani lepharamitha yokuqina kwendawo alilikhulu kakhulu. Lapho i-rough, umkhawulo wokuphakelayo ikakhulukazi amandla okusika. Uma kuqedwa kancane futhi kuqedwa, umkhawulo wokuphakelayo ngokuyinhloko ubulukhuni obungaphezulu.

(3) Ukukhethwa kwejubane lokusika: Isivinini esisheshayo sephuzu onqenqemeni lokusika lwethuluzi oluhlobene nobuso obuzokwenziwa ngomshini endaweni ehamba phambili ehamba phambili ngesikhathi sokusika; iyunithi ingu-m/min. Lapho kukhethwa ukujula kwe-αp kanye nenani lokuphakelayo ƒ, isivinini sokusika esiphezulu sikhethwa ngokusekelwe kokunye, futhi isiqondiso sokuthuthukiswa kwenqubo yokusika ingumshini wejubane eliphezulu.

 

Okwesithathu, umqondo wemishini yokuqina

Komakhenikha, ubuhwaqane busho izici ezincane zejiyomethri yama-pitches, iziqongo, kanye nezigodi endaweni ewumshini. Ingenye yezinkinga zocwaningo olushintshashintshayo. Ubulukhuni bobuso ngokuvamile bakhelwa izindlela zokucubungula ezisetshenziswayo nezinye izici, njengokungqubuzana phakathi kwethuluzi nendawo yengxenye phakathi nokucubungula, ukuguqulwa kwepulasitiki kongqimba olungaphezulu lwensimbi phakathi nokuhlukaniswa kwe-chip, kanye nokudlidliza kwemvamisa ephezulu ohlelweni lokucubungula. Ngenxa yomehluko phakathi kwendlela yokucubungula kanye nezinto zokusebenza, indawo engaphezulu ezocutshungulwa ishiya uphawu olunomehluko wokujula, ukuminyana, ukuma, nokuthungwa. Ubulukhuni bobuso buhlobene eduze nezakhiwo zemishini, ukumelana nokugqokwa, amandla okukhathala, ukuqina kokuxhumana, ukudlidliza, nomsindo wezingxenye eziwumshini. Kunomthelela obalulekile empilweni yesevisi yemikhiqizo yemishini nokuthembeka.

 

Okwesine, ukumelela okungelula

Ngemva kokuba ingxenye engaphezulu seyenziwe ngomshini, ibonakala ibushelelezi futhi ingalingani. Ubulukhuni bobuso bubhekisela ezicini zejiyomethri ezincane ezincane neziqongo nezigodi ezingaphezulu kwengxenye emshinini, ngokuvamile ezakhiwe indlela yokucubungula nezinye izici ezithathiwe. Umsebenzi wobuso bengxenye uhlukile, futhi amanani adingekayo wepharamitha yobushelelezi nawo ahlukile. Ikhodi yokuma kwangaphezulu imakwe engxenyeni yomdwebo ukuze ibonise izici ezingaphezulu okufanele zifinyelelwe ngemva kokuqeda indawo engaphezulu. Kunezinhlobo ezintathu zamapharamitha wobude bokuqina kobuso:

1. Uhlaka lwezibalo kusho ukuchezuka Ra

Incazelo ye-arithmetic yebanga eliphelele phakathi kwephoyinti ekukhonkolo eduze kwesiqondisindlela sokulinganisa (isiqondiso esingu-Y) kanye nomugqa wereferensi ngaphezu kobude besampula.

2, ukungalingani okuncane 10 amaphuzu ukuphakama Rz

Ibhekisela esilinganisweni sesilinganiso sezindawo ezinhlanu eziphakeme kakhulu zokuphakama kwekhonta kanye nesilinganiso sokushona kwesigodi esikhulukazi okuyisihlanu esikhulukazi phakathi kobude besampula.

3, ukuphakama okuphezulu kwe-contour Ry

Ibanga phakathi komugqa ophakeme kakhulu kanye nomugqa ophansi wephrofayela ngaphezu kobude besampula.

Ra. isetshenziswa kakhulu embonini ejwayelekile yokukhiqiza imishini.

 

Okwesihlanu, Umthelela wobunzima ekusebenzeni kwengxenye

Izinga elingaphezulu ngemva kokwenza ucezu lokusebenza lithinta ngokuqondile izici ezingokomzimba, zamakhemikhali, nezomshini zesiqeshana sokusebenza. Ukusebenza komsebenzi, ukwethembeka, nempilo yesevisi yesiqeshana sokusebenza kuncike kakhulu kwikhwalithi engaphezulu yengxenye emaphakathi. Imvamisa, izidingo zekhwalithi ephezulu yezingxenye ezibalulekile ziphakeme kunezingxenye ezijwayelekile ngoba izingxenye ezinekhwalithi engaphezulu zizothuthukisa kakhulu ukuguga kwazo, ukugqwala, nokumelana nokukhathala.
