Makina oyezera ogwirizana (CMMs) amagwiritsidwa ntchito kwambiri m'mafakitale monga makina, zamagetsi, zida, ndi mapulasitiki. Ma CMM ndi njira yothandiza yoyezera ndikupeza deta ya miyeso chifukwa amatha kusintha zida zambiri zoyezera pamwamba ndi zoyezera zodula, kuchepetsa nthawi yofunikira pa ntchito zovuta zoyezera kuyambira maola mpaka mphindi - chinthu chomwe sichingachitike ndi zida zina.
Zinthu Zokhudza Makina Oyezera Ogwirizana: Zinthu Zokhudza Kugwirizana kwa Zinthu mu Miyeso ya CMM. Mu muyezo wa dziko lonse, malo olekerera zinthu mu CMM amatanthauzidwa ngati malo omwe ali mkati mwa malo ozungulira okhala ndi kulekerera kwa t ndi coaxial ndi datum axis ya CMM. Ili ndi zinthu zitatu zowongolera: 1) axis-to-axis; 2) axis-to-common axis; ndi 3) center-to-center. Zinthu Zokhudza Kugwirizana kwa Zinthu mu Miyeso ya 2.5-Dimensional: Zinthu zazikulu zomwe zimakhudza kuyanjana kwa zinthu mu miyeso ya 2.5-dimensional ndi malo apakati ndi axis direction ya chinthu choyesedwa ndi datum element, makamaka axis direction. Mwachitsanzo, poyesa ma cross-section rounds awiri pa datum silinda, mzere wolumikizira umagwiritsidwa ntchito ngati datum axis.
Mabwalo awiri ozungulira amayesedwanso pa silinda yoyezedwa, mzere wowongoka umapangidwa, kenako coaxiality imawerengedwa. Tikaganiza kuti mtunda pakati pa malo awiri olemera pa datum ndi 10 mm, ndipo mtunda pakati pa pamwamba pa datum load ndi gawo lopingasa la silinda yoyezedwa ndi 100 mm, ngati malo apakati pa bwalo lachiwiri lopingasa la datum ali ndi cholakwika choyezera cha 5um ndi pakati pa bwalo lopingasa, ndiye kuti datum axis ili kale 50um kutali ikatambasulidwa ku gawo lopingasa la silinda yoyezedwa (5umx100:10). Pakadali pano, ngakhale silinda yoyezedwa ili coaxial ndi datum, zotsatira za miyeso ya magawo awiri ndi 2.5 zidzakhalabe ndi cholakwika cha 100um (mlingo womwewo wa kulekerera ndi diameter, ndipo 50um ndi radius).
