Kusanthula Mozama Kutsimikizika kwa Metrological kwa CMM

CMM ndi njira yovuta yoyezera yomwe imagwiritsa ntchito ukadaulo wamagetsi, wamakina, wamagetsi, wa makompyuta ndi wowongolera, kotero pali zinthu zambiri zosatsimikizika zomwe zimakhudza zotsatira za muyeso, koma pazida zazing'ono ndi zapakati pamakina, kusiyana kwa kutentha kwa mlengalenga kuchokera ku kutentha kokhazikika (20℃) ndiye chinthu chachikulu chomwe chimakhudza kusatsimikizika kwa muyeso. Kuti muyese zotsatira zolondola za muyeso wa CMM, kutentha kwa mlengalenga kuyenera kulamulidwa mosamala mkati mwa kuchuluka kwa CMM.

1. Kodi njira yodziwira ya Makina Ogwirizanitsa Kodi zotsatira za muyeso zingakhudze bwanji?

Tikudziwa kuti pamene makina ogwirizanitsa akuyeza, Kafukufuku imatumiza chizindikiro pambuyo polumikizana ndi workpiece kuti iyesedwe, kenako malo ogwirizanitsa a probe amasonkhanitsidwa ndi makina owongolera ndi kompyuta, kenako kuwerengera kofunikira kumachitika kuti tipeze zotsatira zomwe tikufuna. Pakadali pano, ma probe ambiri a coordinate atatu ndi a switch type, omwe mfundo yake yopangira imabweretsa malo osiyanasiyana olumikizirana ndi switch m'malo osiyanasiyana, zomwe zimabweretsa zolakwika zozindikira. Cholakwikacho chimakhudza mwachindunji kusatsimikizika kwa zotsatira za coordinate measurement. Chifukwa chake mukufuna kuti cholakwikacho chikhale chochepa momwe mungathere.

2. Kodi zolakwika 21 za ma coordinates atatu ndi ziti?

Pali ma axel atatu oyenda, iliyonse ili ndi cholakwika chimodzi choyimilira ndi zolakwika zisanu za geometric. Zolakwika za geometric zimaphatikizapo zolakwika zowongoka mbali ziwiri ndi zolakwika za angular mbali ziwiri. Pali zolakwika 18 mu ma axel atatu, ndi zolakwika 21 mu verticality pakati pa ma axel atatu.

3. Kodi ndi liti pamene muyenera kuchita kuti mukonze zolakwika 21?

Maziko, kulondola ndi kulinganiza kwa ma coordinates atatu n'kovuta. Ngakhale kuti sizinatchulidwe mu specification, cholakwika cha calibration cha 21 ndi chofunikira pazochitika izi: kuvomerezanso; Cholakwika cha muyeso wa kutalika Cholakwika cha zotsatira za calibration; Ma coordinates pambuyo pa kayendedwe ka makina; Makina ogwirizanitsa amakhazikika.

4. Ndi zida ziti zomwe zimafunika kuti zigwirizane bwino ndi ma coordinates?

Miyezo yofunikira pokonza ma coordinates atatu ndi iyi: kukula kwa giredi yofanana ya chipika choyezera ndi 1000mm; Laser interferometer. Mulingo wamagetsi; Chigamulo cha sikweya; Mpira wamba, ndi zina zotero.
