Kajeno, a re hlahlobeng hore na litlhoko tsa lisebelisoa tsa mochini oa CNC ke life bakeng sa mochini oa drive drive.

Tlhahisong ea sejoale-joale, lisebelisoa tsa mochini oa CNC e se e le lisebelisoa tsa bohlokoa tsa ts'ebetso ka lebaka la melemo ea tsona joalo ka ho nepahala ho phahameng, ts'ebetso e phahameng, le boemo bo phahameng ba boits'oaro. Sistimi ea phepelo ea phepelo ea lisebelisoa tsa mochini oa CNC hangata e sebetsa le sistimi ea phepelo ea servo, e bapalang karolo ea bohlokoa. Ho latela melaetsa ea litaelo e fetisoang ho tsoa ho sistimi ea CNC, e holisa ebe e laola motsamao oa likarolo tse sebetsang. Ha e hloke feela ho laola ka nepo lebelo la motsamao oa phepelo empa hape le ho laola ka nepo boemo ba ho sisinyeha le trajectory ea sesebelisoa se amanang le mosebetsi.

Sistimi e tloaelehileng ea phepelo e laoloang e koalehileng ea sesebelisoa sa mochini oa CNC e entsoe haholo ka likarolo tse 'maloa joalo ka papiso ea maemo, likarolo tsa ho holisa, likarolo tsa ho khanna, mekhoa ea phetisetso ea phepelo ea mochini, le likarolo tsa ho lemoha. Har'a tsona, mochini oa phetisetso ea phepelo ea phepelo ke ketane eohle ea phetisetso ea mochini e fetolang motsamao o potolohang oa enjene ea servo hore e be motsamao oa phepelo oa mochini o sebetsang le sesebelisoa sa lisebelisoa, ho kenyeletsoa lisebelisoa tsa ho fokotsa, sekoti sa lead le linate, likarolo tsa tataiso le likarolo tsa tsona tse tšehetsang. Joalo ka sehokelo sa bohlokoa tsamaisong ea servo, mochini oa phepelo oa lisebelisoa tsa mochini oa CNC ha oa lokela ho ba le ho nepahala ha maemo a holimo feela empa hape o na le litšobotsi tse ntle tsa karabelo tse matla. Karabelo ea sistimi ho latela matšoao a litaelo e lokela ho ba kapele mme botsitso e be bo botle.

Ho netefatsa ho nepahala ha phetisetso, botsitso ba sistimi, le litšoaneleho tse matla tsa karabelo ea sistimi ea phepelo ea litsi tsa machining tse otlolohileng, letoto la litlhokahalo tse tiileng li behiloe pele bakeng sa mochini oa phepelo:

I. Tlhokahalo ea ho se be le lekhalo
Lekhalo la phetisetso le tla lebisa ho khutliseng phoso ea libaka tse shoeleng le ho ama ho nepahala ha ts'ebetso. Ho felisa lekhalo la phetiso ka hohle kamoo ho ka khonehang, mekhoa e kang ho sebelisa shaft ea khokahanyo e nang le pheliso ea lekhalo le lipara tsa phetiso ka mehato ea ho felisa lekhalo e ka amoheloa. Ka mohlala, ka har'a sekoti sa lead le li-nut pair, mokhoa oa ho jarisa linate habeli o ka sebelisoa ho felisa lekhalo ka ho lokisa boemo bo lekanyelitsoeng lipakeng tsa linate tse peli. Ka nako e ts'oanang, bakeng sa likarolo tse kang li-gear transmissions, mekhoa e kang ho lokisa li-shims kapa li-elastic elements li ka boela tsa sebelisoa ho felisa lekhalo ho netefatsa ho nepahala ha phetisetso.

II. Tlhokahalo bakeng sa khohlano e tlase
Ho amohela mokhoa oa phetisetso ea khohlano e tlase ho ka fokotsa tahlehelo ea matla, ho ntlafatsa ts'ebetso ea phetisetso, hape ho thusa ho ntlafatsa lebelo la ho arabela le ho nepahala ha sistimi. Mekhoa e tloaelehileng ea phetisetso ea khohlano e tlase e kenyelletsa litataiso tsa hydrostatic, litataiso tsa rolling, le likurufu tsa bolo.

Litataiso tsa Hydrostatic li theha lera la filimi ea khatello ea oli lipakeng tsa bokaholimo ba tataiso ho fihlela ho thella ho sa amaneng le likhohlano tse nyane haholo. Litataiso tse bilikang li sebelisa liroala tsa lintho tse bilikang holim'a liporo tsa tataiso ho nka sebaka sa ho thella, ho fokotsa khohlano haholo. Li-screws tsa bolo ke likarolo tsa bohlokoa tse fetolang motsamao oa ho potoloha hore e be motsamao oa mola. Libolo li thetheha lipakeng tsa screw ea loto le linate tse nang le khohlano e tlase le phetiso e sebetsang hantle haholo. Likarolo tsena tsa phetisetso e tlase ea likhohlano li ka fokotsa ka nepo ho hanyetsa mochini oa phepelo nakong ea ho sisinyeha le ho ntlafatsa ts'ebetso ea sistimi.

III. Tlhokahalo bakeng sa inertia e tlase
Ho ntlafatsa tharollo ea sesebelisoa sa mochini le ho etsa hore tafole ea ho sebetsa e potlake ka hohle kamoo ho ka khonehang ho fihlela sepheo sa ho latela litaelo, nako ea inertia e fetoletsoeng ho shaft ea drive ke sistimi e lokela ho ba nyane kamoo ho ka khonehang. Tlhokahalo ena e ka finyelloa ka ho khetha tekanyo e nepahetseng ea phetisetso. Ho khetha ka mokhoa o utloahalang tekanyo ea phetisetso ho ka fokotsa nako ea tsamaiso ea inertia ha e ntse e kopana le litlhoko tsa lebelo le potlakisang la ho sebetsa. Ka mohlala, ha ho etsoa sesebelisoa sa ho fokotsa, ho ea ka litlhoko tsa sebele, tekanyo e loketseng ea gear kapa lebanta pulley ratio e ka khethoa ho bapisa lebelo la tlhahiso ea servo motor le lebelo la ho sisinyeha ha worktable le ho fokotsa nako ea inertia ka nako e le 'ngoe.

Ho phaella moo, mohopolo oa moralo o bobebe o ka boela oa amoheloa, 'me lisebelisoa tse nang le boima bo bobebe li ka khethoa ho etsa likarolo tsa phetisetso. Mohlala, ho sebelisa lisebelisoa tse bobebe joalo ka motsoako oa aluminium ho etsa sekoti sa loto le lipara tsa linate le likarolo tsa tataiso ho ka fokotsa inertia ka kakaretso ea sistimi.

IV. Tlhokahalo ea ho satalla holimo
Sistimi ea phetisetso e thata e ka netefatsa ho hanyetsa tšitiso ea kantle nakong ea ts'ebetso le ho boloka ts'ebetso e tsitsitseng ea ts'ebetso. Ho ntlafatsa ho tiea ha sistimi ea phetiso, mehato e latelang e ka nkuoa:
Fokotsa ketane ea phetisetso: Ho fokotsa likhokahano tsa phetisetso ho ka fokotsa ho senyeha ha sistimi le ho ntlafatsa ho satalla. Ka mohlala, ho sebelisa mokhoa oa ho khanna ka ho toba sekoti sa moeta-pele ka motlakase ho boloka lihokelo tsa phetiso ea mahareng, ho fokotsa liphoso tsa phetisetso le deformation elastic, le ho ntlafatsa ho satalla ha sistimi.
Ntlafatsa ho satalla ha sistimi ea phetisetso ka ho kenya pele: Bakeng sa litataiso le li-screw tsa li-ball, mokhoa o kentsoeng pele o ka sebelisoa ho hlahisa phallo e itseng lipakeng tsa lintho tse roala-hang le liporo tsa tataiso kapa likurufu tsa lead ho ntlafatsa ho tiea ha sistimi. The lead screw support e etselitsoe ho ts'oaroa lipheletsong ka bobeli mme e ka ba le sebopeho se otlolletsoeng pele. Ka ho sebelisa tsitsipano e itseng ea pele ho screw ea lead, matla a axial nakong ea ts'ebetso a ka hanyetsoa mme ho satalla ha screw ea lead ho ka ntlafatsoa.

V. Tlhokahalo ea maqhubu a phahameng a resonant
Maqhubu a phahameng a resonant a bolela hore tsamaiso e ka khutlela kapele ho boemo bo tsitsitseng ha e le tlas'a tšitiso ea ka ntle 'me e na le khanyetso e ntle ea vibration. Ho ntlafatsa maqhubu a resonant ea sistimi, lintlha tse latelang li ka qalisoa:
Ntlafatsa moralo oa likarolo tsa phetiso: Rala sebopeho le boholo ba likarolo tsa phetiso joalo ka likurufu tsa loto le liporo tsa tataiso ho ntlafatsa maqhubu a tsona a tlhaho. Ka mohlala, ho sebelisa sekoti sa loto ho ka fokotsa boima ba 'mele le ho ntlafatsa maqhubu a tlhaho.
Khetha lisebelisoa tse loketseng: Khetha lisebelisoa tse nang le modulus e phahameng ea elastic le density e tlase, joalo ka titanium alloy, joalo-joalo, e ka ntlafatsang ho satalla le maqhubu a tlhaho a likarolo tsa phetisetso.
Eketsa damping: Keketseho e nepahetseng ea damping ka har'a sistimi e ka ja matla a vibrate, ea fokotsa tlhoro ea molumo, le ho ntlafatsa botsitso ba sistimi. The damping ea tsamaiso ka eketsoa ka ho sebelisa damping thepa le ho kenya dampers.

VI. Tlhokahalo bakeng sa karo-karolelano e loketseng ea damping
Karo-karolelano e nepahetseng ea damping e ka etsa hore sistimi e tsitse kapele ka mor'a ho khathatseha ntle le ho fokotsa ho thothomela ho feteletseng. Ho fumana tekanyo e nepahetseng ea ho senya, taolo ea tekanyo ea ho senya e ka finyelloa ka ho fetola mekhoa ea tsamaiso e kang li-parameter tsa damper le coefficient ea likhohlano tsa likarolo tsa phetisetso.

Ka bokhutšoanyane, ho fihlela litlhoko tse tiileng tsa lisebelisoa tsa mochini oa CNC bakeng sa mekhoa ea phepelo ea phepelo, letoto la mehato ea ntlafatso le tlameha ho nkuoa. Mehato ena e ke ke ea ntlafatsa feela ho nepahala ha ts'ebetso le ts'ebetso ea lisebelisoa tsa mochini empa hape e matlafatsa botsitso le ts'epahalo ea lisebelisoa tsa mochini, ho fana ka ts'ehetso e matla bakeng sa nts'etsopele ea tlhahiso ea morao-rao.

Lits'ebetsong tse sebetsang, ho boetse hoa hlokahala ho nahana ka lintlha tse fapaneng ka botlalo ho latela litlhoko tse ikhethileng tsa ts'ebetso le lisebelisoa tsa mochini le ho khetha mokhoa o nepahetseng oa phetisetso ea phepelo le mehato ea ntlafatso. Ka nako e ts'oanang, ka tsoelo-pele e tsoelang pele ea saense le thekenoloji, lisebelisoa tse ncha, theknoloji le likhopolo tsa moralo li lula li hlaha, tse fanang ka sebaka se pharaletseng bakeng sa ho ntlafatsa ts'ebetso ea mekhoa ea phetisetso ea phepelo ea lisebelisoa tsa mochini oa CNC. Nakong e tlang, mochini oa phepelo ea phepelo ea lisebelisoa tsa mochini oa CNC o tla tsoela pele ho nts'etsapele ka lehlakoreng la ho nepahala ho holimo, lebelo le phahameng, le ts'epo e phahameng.
