Galimoto

Ponena za makina a injini yamagalimoto, dzenje la oblique oil ndi dzenje lotsogolera ma valve nthawi zambiri amagwiritsidwa ntchito. Kawirikawiri mtundu uwu wa kapangidwe uli ndi ngodya yokhala ndi maziko opangira. Kulondola kwawo pamakina ndi kwakukulu kwambiri, kumachita gawo lofunika kwambiri pakupanga injini. Komabe, momwe mungayezere molondola mtengo weniweni wa zida zopangira, vuto lakhala lofunika kuthetsedwa mwachangu.

Kukula mwachangu kwa ukadaulo wamakono woyezera, makina oyezera ogwirizana tsopano akutha kuyeza mwanzeru. Pa mabowo opendekeka, tingagwiritse ntchito probe yozungulira yomwe imatha kuyeza mosavuta mbali iliyonse. Koma ena mwa CMM amagwiritsa ntchito mutu woyezera womwe sungazungulire momasuka, kuyeza kuwerengera ngodya ndi kovuta kwambiri. Koma pogwiritsa ntchito chiphunzitso cha ngodya ziwiri zozungulira, mutha kupitiliza ntchito yowerengera ngodya. Chifukwa chake mutha kulipira ntchito yoyeserera yosakwanira, mutha kuyeza ngodya ya dzenje lopendekeka molondola kwambiri ndi zina zotero.

Zidutswa zogwirira ntchito zimayikidwa mwachisawawa mu malo oyezera a CMM, mwina zimapendekeka mumlengalenga, zomwe tiyenera kuzilinganiza, komanso kupanga makina ozungulira oyezera zida zoyezera ofanana ndi zigawo za chimango chofotokozera, kenako kupanga work-piece coordinate pa work-piece.

Ngati chogwirira ntchito chili bwino pa benchi yogwirira ntchito, chikhoza kukhala ndi ma axis awiri okha, koma pamalo opendekerana. Izi zikutanthauza kuti pali public axis ya ma coordinate reference frame awiri. Timangofunika kuzungulira ma axe awiri omwe ali olunjika ku invariable axis, kuti azikhala ofanana. Kupeza kwa magawo awiri ndikokwanira.

Zigawo zimapeza mfundo pogwiritsa ntchito masamu kuti zidziwe komwe mzere wa mzere kapena mzere wachiwiri uli, kotero kuti dongosolo logwirizanitsa gawolo, njira yomangira mizere iwiri yokha ndi yomwe ingapezeke kuti mzere wozungulira ukhale wofanana ndi kusunga mgwirizano wa mzere wa anthu onse ukhale wokhazikika.

Pamene gawo lili ndi dongosolo la ma coordinate awiri, ngati ubale pakati pa dongosolo la ma coordinate awiri uli ndi malingaliro enaake, nthawi ino ikhoza kukhala yoyambirira kutengera kulinganiza kwa 3 d ndi kuzungulira kwa ngodya ya kulinganiza kwa magawo awiri.
