Ngokuthuthuka okusheshayo kokukhiqiza okuphezulu,Isikhungo sokulungisa i-CNC esine-axis emihlanusezibe yimishini eyinhloko yokucubungula izingxenye eziyinkimbinkimbi ezimbonini ezifana nezindiza, ukwenza isikhunta, kanye nezimoto. Kodwa-ke, njengoba kunezinhlobo eziningi kangaka ezitholakala emakethe, amabhizinisi angakwenza kanjani ukukhetha kwesayensi okulinganisela ukusebenza kahle, ukunemba, kanye nezindleko? Lesi sihloko sifingqa ngokuhlelekile izindlela zokukhetha ezibalulekile zezikhungo zomshini ezine-axis ezi-5, sigxile kusayizi womsebenzi, ukusebenza kwe-spindle, amazinga okunemba, kanye nezinhlelo ze-CNC.
I. Isimiso Sokufaniswa Kosayizi Wezinto Zokusebenza
Into yokuqala okufanele uyicabangele ekukhetheni usayizi womsebenzi wakho, ikakhulukazi usayizi wetafula kanye nokuhamba kwe-Z-axis. Ukufanisa usayizi ngendlela efanele kusiza ukugwema ukuphazamiseka kanye nokushayisana ngesikhathi somshini. Isimiso esijwayelekile yilesi:
|Ukuphakama kwento yokusebenza + ubude bethuluzi + imvume yokuphepha ≤ ukuphakama okuphezulu komshini
Isibonelo, uma umsebenzi wakho ungama-200mm ukuphakama, ithuluzi lingama-150mm ubude, kanti indawo yokuphepha ingama-50mm, ukuphakama okuphezulu komshini wokugaya kufanele okungenani kube ngu-400mm ukuqinisekisa ukucutshungulwa okuphephile nokubushelelezi.
II. Ukukhethwa Okunengqondo Kokusebenza Kwe-Spindle
Ukusebenza kwe-spindle kuthinta ngqo ukusebenza kahle kwemishini kanye nekhwalithi. Izinto ezahlukene zidinga isivinini namandla ahlukene e-spindle:
·I-Aluminium ne-Graphite: Kunconywa ama-spindle anesivinini esikhulu (~30,000 RPM) ukuze asetshenziswe kahle futhi aqede kahle indawo.
·Ama-Titanium Alloys: Ngenxa yamandla aphezulu, isivinini se-spindle esingaba ngu-15,000 RPM siyalulekwa ukunciphisa ukuguguleka kwamathuluzi nokuthuthukisa ukuzinza.
·Ukujika Okukhulu (isb., Ukujika Okuqinile Kwe-Impeller): Kudinga i-spindle ene-torque ephezulu enamandla angaphezu kuka-40kW ukuqinisekisa ukusebenza okuqinile nokuzinzile kokujika.
·Ukuqedwa Kwesikhunta: Kunconywa ama-spindle adonsa ngqo avibration aphansi ukuze kuncishiswe ukudlidliza futhi kuthuthukiswe ikhwalithi kanye nokunemba kwendawo yesikhunta.
III. Izindinganiso Zokucacisa Ukuhlela
Izimboni ezahlukene zinezidingo ezahlukene zokunemba:
·Izindiza: Ngokuvamile kudinga ukunemba okuphezulu kwezinga le-IT6.
·Imboni Yesikhunta: Ngokuvamile ukunemba kwezinga le-IT8 kwanele.
Lo mehluko ezindinganisweni zokunemba unquma ukukhethwa kwemishini kanye nokugeleza kwenqubo.Imishini ye-CNC enembile kakhulukungabiza kakhulu kodwa kuhlangabezana nezidingo zekhwalithi eqinile. Ngesikhathi esifanayo, izinhlelo zokusebenza ezithinta izindleko zingakhetha imishini ehlangabezana nezidingo zokunemba ezisebenzayo ukuze kube nokulinganisela komnotho nokusebenza kahle.
IV. Uhlelo lwe-CNC kanye nobuchwepheshe bemishini obusebenza ngesikhathi esisodwa obuyi-5-Axis
Umshini wokugaya onama-axis ama-5 ngesikhathi esisodwa uyisisekelo sesikhungo sokugaya se-CNC sama-axis ama-5 sesimanje. Ngokuhamba okuhlelekile kwama-axis aqondile e-X, Y, kanye ne-Z kanye nama-axis ajikelezayo e-A, C (noma B, C), umshini ungacubungula izindawo eziyinkimbinkimbi kusuka kuma-engeli amaningi kanye neziqondiso. Lokhu akugcini nje ngokuthuthukisa kakhulu ikhono lomshini wokugaya izingxenye eziyinkimbinkimbi, kodwa futhi kunikeza inzuzo ebalulekile yokubopha okukodwa - ubuso obuningi kanye nezinqubo zingaqedwa ngokusetha okukodwa, kugwenywe amaphutha okubeka kanye nokuqondanisa okuphindaphindiwe kusuka ekubambeni okuningi, ngaleyo ndlela kuthuthukiswe kokubili ukunemba nokusebenza kahle.
Uma ukhetha uhlelo, kubalulekile ukugxila ekusebenzeni kwe-algorithm yohlelo lwe-CNC, indlela yokusebenzisa ukuxhumana kwe-five-axis linkage, kanye nekhono lokwenza ngcono izindlela zomshini, njengoba lezi zici zithinta ngqo ikhono lokucubungula lomshini kanye nekhwalithi yomkhiqizo wokugcina. Izinhlelo zokulawula ze-five-axis CNC ezisetshenziswa kakhulu zifaka phakathi i-SIEMENS SINUMERIK ONE kanye ne-HEIDENHAIN TNC 640.
·Uhlelo lwe-SIEMENS SINUMERIK ONE CNC: Lufanelekela imishini yokukhanda ubuso enembile kakhulu ezimbonini ezifana nezindiza kanye nemishini yokunemba, enezici zokulawula zedijithali ezithuthukisiwe kanye nemisebenzi yokulingisa.
·Uhlelo lwe-HEIDENHAIN TNC 640 CNC: Lwaziwa ngama-algorithms alo okuphendula ngesivinini esikhulu, luhamba phambili ezinhlelweni zokusebenza ezidinga imishini esheshayo, njengokwenza isikhunta kanye nokukhiqizwa kwezingxenye zezimoto.
Singazihlomisa lezi zinhlelo ze-CNC ngokuvumelana nezidingo zamakhasimende ukuqinisekisa ukusebenza kahle komshini nokuhlangabezana nezidingo zomshini wokugaya izingxenye eziyinkimbinkimbi osebenza kahle futhi onembile.
V. Amacala Okusetshenziswa Ajwayelekile
Isikhungo somshini we-CNC esisebenza ngasikhathi sinye esingu-5-axisisetshenziswa kabanzi ku:
·Ama-impeller enjini yezindiza (i-aluminium, i-titanium alloys)
·Amadiski efeni (ama-alloy e-aluminium)
·Izingxenye ze-Helical (ama-aluminium alloys)
·Ama-Blisk nama-structural disk (ama-alloy e-titanium)
·Ama-casing enjini (ama-alloy e-titanium, ama-superalloy)
·Izingxenye ze-turbine (insimbi engagqwali, ama-superalloy)
Ngokuhlela amapharamitha omshini ngokwezinto zokwakha ezahlukene kanye nezimo zomsebenzi, ungathuthukisa kakhulu ukusebenza kahle komshini kanye nekhwalithi yomkhiqizo.
Isifinyezo
Ukuze sikusize ukhethe umshini ofanele ngokushesha, sicela unikeze ulwazi olulandelayo uma usithinta:
·Ubukhulu bomsebenzi wakho (ukuphakama, ububanzi, njll.)
·Izinto eziyinhloko zomshini (isb., i-aluminium alloy, i-titanium alloy, njll.)
·Izinqubo eziyinhloko zomshini (ukugoqa, ukuqeda, njll.)
·Izidingo ezithile zokunemba (isb., IT6, IT8, njll.)
·Isivinini sokuphotha esifunekayo kanye nobubanzi bamandla
·Noma yiziphi izidingo ezikhethekile zohlelo lwe-CNC noma ukuxhumanisa okungu-5-axis
Lolu lwazi luzosisiza ukuthi sincome okufanele kakhuluIsixazululo somshini wokugaya we-CNC onama-axis ama-5kwakho.
Ukukhethwa kwesayensi kwesikhungo somshini esine-axis emihlanu kuyisinyathelo esibalulekile sokuthuthukisa izinga lakho lokukhiqiza kanye nokuncintisana emakethe. Uma unemibuzo eminingi mayelana nokukhetha, zizwe ukhululekile ukuxhumana nathi, i-OTURN izokunikeza izeluleko zobungcweti kanye nezinsizakalo ezenziwe ngokwezifiso!
