5isikhungo sokulungisa imishini esiqondile se-axissezibe yimishini ebalulekile ekukhiqizeni okusezingeni eliphezulu ngenxa yekhono lazo lokufeza ukucutshungulwa okunembe kakhulu kwezingxenye eziyinkimbinkimbi. Ukunemba kwazo kokucutshungulwa akunqumi nje kuphela ikhwalithi yomkhiqizo kodwa futhi kumelela umongo wokuncintisana kwemishini. Ukufeza lokhu kucutshungulwa okunembe kakhulu kuncike emizamweni ehlanganisiwe yezici eziningi, okuhlanganisa isakhiwo semishini, uhlelo lwe-CNC, kanye nokutholwa kanye nokunxeshezelwa, okwakha uhlelo lokuqinisekisa ukunembile oluhlelekile noluphelele. Ukuhlaziywa okuningiliziwe okulandelayo kwesixhumanisi ngasinye esiyisihluthulelo kuzokusiza uqonde i-logic yayo eyisisekelo kanye nobuchwepheshe obuthuthukisiwe.
IUmklamo Wokuqina Kwesakhiwo Semishini: Isisekelo Esiqinile Sokunemba
Ukuqina kwesakhiwo semishini kunquma ngqo ukuqina kwemishini kanye nokumelana nokuguquguquka kwayo ngesikhathi somshini.5-axis VMC, umbhede kanye nekholomu kusebenza “njengohlaka” lomshini wonke. Ngokuvamile zakhiwe ngensimbi eqinile noma i-granite enamandla kakhulu. Ukwelashwa kokuguga kuqeda ngempumelelo ukucindezeleka kwangaphakathi futhi kunciphisa kakhulu ukuguquguquka okubangelwa ukusika imithwalo. Izingxenye ze-guideway kanye ne-lead screw drive ziyisihluthulelo sokuqinisekisa ukunemba kokunyakaza okuqondile, okudinga ukulawulwa okuqinile kokunemba okuphelele. Ama-rolling guides asebenzisa ukulayisha kwangaphambili ukuze aqede ukuhlehla emuva futhi athuthukise ukuqina kokubeka. Ama-ball screws asebenzisa isakhiwo sokulayisha kwangaphambili esine-double-nut ukuze aqede ngempumelelo ukuhlehla emuva futhi anciphise amaphutha okudlulisa. Uhlelo lokusekela lwama-axes ajikelezayo (njenge-A-axis kanye ne-C-axis) lubalulekile. Ama-roller bearings aphambene ngokunemba okuphezulu kanye namagiya e-worm asetshenziswa ukumelana nemithwalo ye-radial kanye ne-axial ngenkathi kugcinwa ukuvuleka kokujikeleza ngaphakathi kwebanga le-angle kusuka kumasekhondi ambalwa kuya kwamashumi, okuthuthukisa kakhulu ukunemba kokubeka kwe-angular. Iyunithi ye-spindle isekelwa ama-ceramic bearings anembile noma ama-aerostatic bearings. Ukulinganisela okunamandla kuqinisekisa ukuthi i-radial runout kanye ne-axial play kulawulwa ezingeni le-micron ngesikhathi sokujikeleza kwesivinini esikhulu, okuvimbela ukudlidliza ekubeni umthombo wephutha lomshini.
II. Ukulawulwa Okunembile Kohlelo lwe-CNC—“Ubuchopho” Bokunemba
Ukunemba komshini wokugaya onama-axis amahlanu akuxhomekile ekuqineni komshini kuphela kodwa futhi nasekulawulweni okunembile kokunyakaza kohlelo lwe-CNC. Uhlelo lubala umzila kanye nesivinini se-axis ngayinye ngesikhathi sangempela futhi, ngokusebenzisa ama-algorithms okuxuba, ludala indlela yokunyakaza eqhubekayo nebushelelezi, okuqinisekisa ukuthi umzila wamathuluzi uhlangabezana nezidingo zomklamo. Ubuchwepheshe bokulawula i-Feedforward bubikezela umzila futhi bulungisa umphumela we-servo motor kusengaphambili, kunciphisa kakhulu iphutha elilandelayo.
Uhlelo lokuphendula ngesikhundla lusebenzisa isikali noma i-encoder enesinqumo esiphezulu ukuqoqa idatha yesikhundla se-axis yangempela ngesikhathi sangempela. Ihlanganiswe ne-algorithm yokulawula i-PID closed-loop, ilungisa ngokushesha ukuphambuka kokubeka, igcine iphutha lokubeka ngaphakathi kwamazinga e-micron. Emishinini ye-five-axis, uhlelo lwe-CNC lusebenzisa imodeli ye-kinematic ukuguqula ngokunembile izixhumanisi zobudlelwano bokunyakaza obuyinkimbinkimbi phakathi kwama-rotary kanye nama-linear futhi ifinyelele ukunemba okunembile kokubeka amathuluzi kunoma iyiphi indawo esikhaleni, iqinisekisa ukusebenza okunembile kakhulu emishinini ye-five-axis.
III. Izindlela Zokuthola Nokunxephezela: Abaqaphi Bokunemba Okuguquguqukayo
Ukulinganisa okunembile kanye nesinxephezelo esifike ngesikhathi kubalulekile ekugcineni ukunemba kwemishini isikhathi eside. Ngaphambi kokuthunyelwa, imishini kumele ihlolwe ngokuphelele iphutha lokubeka, iphutha lokuphindaphinda, kanye nokubuyela emuva ku-axis ngayinye kusetshenziswa amathuluzi anokunemba okuphezulu njenge-laser interferometers kanye nama-ballbars. Lokhu kuqinisekisa ukuthi wonke amaphutha okusebenza aqoshwa ngedijithali futhi alungiswe ngesinxephezelo sepharamitha yesistimu ye-CNC.
Ukwanda kokushisa kanye nokuguquguquka komshini okubangelwa ukushintshashintsha kokushisa kuyizingozi ezinkulu zokunemba ngesikhathi somshini wokusebenza isikhathi eside. Izinzwa zokushisa ziqapha izinga lokushisa elizungezile lemishini kanye nokwenyuka kwezinga lokushisa kwe-spindle kanye nemigwaqo ngesikhathi sangempela. Amasu okubuyisela amandla aguquguqukayo, ahlanganiswe namamodeli amaphutha okushisa asunguliwe, anciphisa kakhulu umthelela wokuphazamiseka kwezinga lokushisa ekunembeni komshini.
Ukulinganisa okuvamile nakho kubalulekile ekugcineni ukunemba. Ngokuqhathanisa nezingxenye ezijwayelekile kanye nokuqinisekiswa kwamaphuzu amaningi kusetshenziswa amathuluzi okuhlola ukunemba, ukuphambuka kokunemba okubangelwa ukuguguleka komshini noma izingxenye ezikhululekile kungatholakala ngokushesha, okuvumela ukuthi amapharamitha emishini alungiswe futhi alungiswe ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwemishini.
IV. Ukulawula Okunembile Okuhlelekile—Kusukela Ekuqondeni Okuphezulu Okungaguquki Kuya Ekuzinzeni Okuguquguqukayo
Ukuqinisekiswa kokunemba kwe-5Isikhungo somshini esiqondile se-axis siwumphumela wokubambisana okuhambisanayo nokuhlelekile kwezingxenye ezahlukahlukene. Isakhiwo somshini sinikeza isisekelo esiqinile, uhlelo lwe-CNC luvumela ukulawula ukunyakaza okunembile, kanye nendlela ephelele yokuthola nokubuyisela iqinisekisa ukunemba okuguquguqukayo.
Lolu hlelo lokulawula ukunemba okuhlelekile alugcini nje ngokuqinisekisa ukunemba komshini okuhlanzekile lapho imishini ingashintshi, kodwa futhi lumelana ngempumelelo nezici ezahlukahlukene zokuphazamiseka njengokudlidliza, ukuguqulwa kokushisa, kanye nokushintshashintsha komthwalo ezindaweni zomshini eziyinkimbinkimbi, kufezwe izidingo zomshini ezinembe kakhulu zezingxenye eziyinkimbinkimbi.
Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza obuhlakaniphile, ubuchwepheshe bokunxephezela obuhambisana nokuguquguquka obuhlanganisa ubuhlakani bokwenziwa kanye nokuhlaziywa kwedatha enkulu busetshenziswe kancane kancane, okwethula impumelelo ekuqinisekisweni kokunemba kwe5isikhungo sokulungisa imishini se-axisr, okuthuthukisa amakhono abo okukhiqiza kanye nokuncintisana emakethe.
Ngamafuphi, ukunemba okuphezulu kwe5Izikhungo zomshini eziqondile ze-axis aziwona umphumela wengozi, kodwa umphumela wokubambisana okuhlanganisiwe nokucophelela kwezinsika ezintathu: ukwakheka kwemishini, ama-algorithm okulawula, kanye nokutholwa kanye nokubuyiselwa kwemali. Kuphela ngokwakha ngokwesayensi nangokuqhubeka nokwenza ngcono lolu hlelo lokuqinisekisa ukunemba lapho singahlangabezana nezidingo zokunemba eziqinile zokukhiqiza okuphezulu kwezingxenye eziyinkimbinkimbi futhi sithuthukise ukukhiqiza okuhlakaniphile ezingeni eliphakeme.
Ukuze uthole ulwazi olwengeziwe, sivakashele ku-EMO, Hall 15, Booth B54, Septhemba 22-27, 2025. Sizokukhombisa okwakamuva5-ubuchwepheshe bokusebenza ngomshini, ulwazijikaimishini esezingeni eliphezulu, futhi uhlanganyele ezingxoxweni ezijulile nochwepheshe bemboni. Sikumema ngobuqotho ukuthi nixoxe ngekusasa lokukhiqiza okuhlakaniphile futhi nivule isahluko esisha ekusetshenzisweni kwemishini okunembe kakhulu!
