Uburanga kuri CMM PROCISION

ByinshiImashini za CMM (Guhuza imashini zo gupima) byakozwe naGranite.

Imashini zo gupima (CMM) nigikoresho cyo gupima byoroshye kandi cyateje imbere uruhare runini mu bidukikije, harimo no gukoresha muri laboratoire gakondo, hamwe nuruhare ruheruka gushyigikira umusaruro mubidukikije. Imyitwarire yubushyuhe bwa CMM temgol ihinduka ikintu cyingenzi hagati yinshingano zayo no gusaba.

Mu kiganiro gishurutse gutangaza, na Renishaw, ingingo yo kureremba kandi yamenyesheje umurongo wa tekinike yo gushiraho imitwe yaganiriweho.

Enter Umunzani ufite ubusebya nyabagirane yigenga kugirango asimburwe (kureremba) cyangwa nyaburanga biterwa na substrate (shingiro). Igipimo kireremba kandi amasezerano akurikije imiterere yubushyuhe bwibikoresho, mugihe igipimo cyagutse kandi cyamasezerano ku kigero kimwe na substrate. Ubuhanga bwo gupima igipimo butanga inyungu zitandukanye kubisabwa bitandukanye: Ingingo ya Renishaw itanga ikibazo aho igipimo cyingenzi gishobora guhitamo igisubizo cyimashini za laboratoire.

Cmms ikoreshwa mugufata amakuru atatu yo gupima ibipimo ngenderwaho, ibice byafashwe, nka moteri ya moteri na moteri ya jete, murwego rwo kugenzura ubuziranenge. Hariho ubwoko bune bwibanze bwamashini yo gupima: ikiraro, cantilever, gantry nukuboko gutambitse. CMM-Ubwoko bwa CMMS nicyo gisanzwe. Mu gishushanyo cya CMM ikiraro, quill quill yashyizwe ku bubiko bugenda ku kiraro. Ikiraro gitwarwa nubuyobozi bubiri buyobora mu cyerekezo cya y-axis. Moteri itwara uruhuguro, mugihe igitugu gitandukanye gitandukanijwe mubisanzwe: Imiterere yikiraro iyobowe / ishyigikiwe nibikorwa byindege. Imodoka (X-Axis) na Quill (z-axis) irashobora gutwarwa numukandara, screw cyangwa moteri yumurongo. CMM yagenewe kugabanya amakosa asubirwamo nkuko ibi bigoye kwishyura umugenzuzi.

Imikorere miremire ikubiyemo uburiri bwo mu bushyuhe bwinshi bwa granite hamwe na gantry gantry / ibara, hamwe na inertia yometseho ifatanije na sensor kugirango igire akamaro. Amakuru yakozwe kugirango akemure ko ibice byujuje ibyateganijwe. Umurongo wa Precional wo hagati washyizweho kuri X, y na z anees ishobora kuba metero nyinshi ndende ku mashini nini.

Ikiraro gisanzwe cya Granite-Ubwoko Cmm yakorewe mucyumba gikonjesha, hamwe n'ubushyuhe bwa 20 ± 2 ° C, aho ubushyuhe bw'icyumba cy'amasaha atatu buri saha, byemerera misa y'ubushyuhe buhoraho kugira ngo ubushyuhe buringaniye bwa 20 ° C. Umurongo ureremba utagira umunda washyizweho kuri buri CMM uwigenga cyane kuri granite kandi ugasubiza byihuse impinduka zikirere zidafite ubushyuhe bwamashusho ya granite. Ibi byaganisha ku kwagura cyane cyangwa kugabanuka kwigipimo hejuru ya 3m inyuguti zisanzwe za 60 μm. Uku kwaguka birashobora gutanga ikosa rikomeye rigoye kwishyura kubera iyo ari igihe-gitandukanye.

Igipimo cya Sublices gishya ni amahitamo ahitamo muri uru rubanza: Igipimo cyingenzi cyaguka gusa hamwe na granite yo kwagura ubushyuhe (cte) cya submal (cte) cya sublice kandi, zagaragaza impinduka nke mugusubiza impyisi ntoya mu kirere. Igihe kirekire impinduka mubushyuhe igomba gukomeza gusuzumwa kandi ibi bizagira ingaruka ku bushyuhe bugereranywa bwa subrmal subree. Indishyi zubushyuhe ntizikosora nkuko umugenzuzi akeneye kwishyuza imyitwarire yubushyuhe bwamashini bitabanje gutekereza ku myitwarire yubushyuhe.

Muri make, sisitemu ya enter hamwe na subling yashizweho nicyo gisubizo cyiza cya cte yimyanda hamwe na cte cyangwa subrmal yubushyuhe buke hamwe nibindi bikorwa bisaba urwego rwo hejuru rwimikorere miremire. Ibyiza byo gusangirwa birimo koroshya ubutegetsi bwubushyuhe nubushobozi bwo kugabanya amakosa yo gupima kubera, urugero, gutandukanya ubushyuhe bwimashini zaho.
