CNC-pingi on arvutiga varustatud masin mehaaniliste t\u00f6\u00f6de t\u00f6\u00f6tlemiseks. L\u00fchend CNC tuleneb ingliskeelsest terminist\u00a0Arvutip\u00f5hine arvjuhtimine<\/a>. M\u00f5iste ise viitab nende masinate t\u00f6\u00f6p\u00f5him\u00f5ttele. Seega on tegemist arvutusarvutiga, millel on numbrilised meetodid. Neid pakuvad spetsiaalsed tarkvaravahendid, mis kontrollivad ja j\u00e4lgivad neid masinaid ja nende p\u00f5hikomponente. T\u00f6\u00f6riistade liikumise eest hoolitsevad servo- v\u00f5i samm-mootorid. CNC-pingi elektroonilist p\u00f5hi\u00fcksust nimetatakse CNC-juhtimispuldiks ja seda v\u00f5ib k\u00e4sitada omamoodi vahe\u00fcksusena arvuti ja servo- v\u00f5i samm-mootorite vahel, mis hoolitsevad CNC-pingi k\u00f5igi m\u00e4\u00e4ratletud telgede liikumise eest.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Milline on CNC-pingi t\u00f6\u00f6p\u00f5him\u00f5te?<\/h2>

CNC-pingi t\u00f6\u00f6p\u00f5him\u00f5te on materjali t\u00e4pne mehaaniline t\u00f6\u00f6tlemine, mis on fikseeritud kinnitusseadmega, mis tagab materjali v\u00f5i tooriku fikseeritud asendi. Toorik paigutatakse kindlasse kohta ja j\u00e4\u00e4b sinna kuni mehaanilise t\u00f6\u00f6tlemise l\u00f5puni. Enamasti piisab sellest, et CNC-seade muudab t\u00f6\u00f6riista asendit kolme p\u00f5hitelje X-, Y- ja Z-suunas. Loomulikult on t\u00e4nap\u00e4eval turul v\u00e4ga arenenud CNC-pingid, mis v\u00f5imaldavad t\u00f6\u00f6riista liikumist mitmel teljel, need v\u00f5ivad liikuda kuni uskumatul hulgal kaheksal teljel ja k\u00f5ige arenenumad masinad v\u00f5ivad liikuda ka rohkem kui kaheksas suunas, mida peab toetama\u00a0CNC kontroller<\/a>. Erinevalt robotitest, mis on samuti arvutiga juhitavad masinad ja mida kasutatakse peamiselt tootmisliinidel, on CNC-t\u00f6\u00f6pinkide puhul t\u00f6\u00f6deldav detail tavaliselt fikseeritud kambris ja operaator paigaldab ja eemaldab selle k\u00e4sitsi.<\/p>

Millised on CNC-pingi peamised komponendid?<\/h2>

Nagu eespool mainitud, on arvutiprogramm CNC-pingi programmeerimise aluseks. CAD-CAM tarkvaravahendeid kasutatakse materjali t\u00f6\u00f6tlemise plaani koostamiseks. Need joonised koos plaaniga teisendatakse G-koodiks, mida CNC-masin m\u00f5istab. G-kood annab telgede asukohad, mida m\u00f6\u00f6da masinpea liigub. Iga rida \u00fctleb seega meile masina uue telje asendi. M-kood seevastu m\u00e4\u00e4ratleb mitmesugused funktsioonid, mis v\u00f5ivad olla seotud k\u00e4ivitamise, seiskamise, s\u00f6\u00f6tmiskiiruse, t\u00f6\u00f6riista vahetamise, kambri ukse avamise jne. \u00dcheks selliseks CNC-juhtimistarkvaraks on Mach3 v\u00f5i veel parem selle moodsam versioon.\u00a0Mach4<\/a>.<\/p>

J\u00e4rgmine v\u00e4ga oluline komponent on masina mehaaniline konstruktsioon. See on \u00e4\u00e4rmiselt oluline suure t\u00e4psuse ja t\u00f6\u00f6kindluse tagamiseks telgede l\u00f5putute iteratsioonide puhul. Eelk\u00f5ige on masina mehaanilise struktuuri j\u00e4ikus oluline t\u00e4psuse ja korratavuse seisukohalt. Suure koormuse t\u00f5ttu on CNC-pingid enamasti massiivsed ja rasked. Mehaanilised komponendid vajavad pika eluea tagamiseks regulaarset ja hoolikat hooldust, mis toimub eelnevalt kindlaksm\u00e4\u00e4ratud ajavahemike j\u00e4rel, mis on kohandatud masina t\u00f6\u00f6tundide arvule. Hooldus peab olema hoolikalt ajastatud ka tootmises.<\/p>
