Nigute ushobora kugenzura ubugororangingo bwa granite?

1. Perpendicularité yuruhande rwumurongo ugana hejuru yakazi: Shyira granite igororotse ku isahani iringaniye. Hisha igipimo cya terefone, gifite igipimo cya 0.001mm, unyuze kumurongo usanzwe uzengurutswe na zeru kuri kare. Noneho, kimwe, shyira igipimo cyerekeranye kuruhande rumwe rugororotse. Gusoma ibipimo byo gusoma ni ikosa rya perpendicularity kuruhande. Na none, gerageza ikosa rya perpendicularity kurundi ruhande, hanyuma ufate ikosa ntarengwa.

2. Gusya hejuru hejuru yicyuma cyangwa kugorora byibuze byibuze kimwe kugirango ugaragaze aho utandukaniye kumurimo. Noneho, shyira urupapuro rubonerana (nk'urupapuro rwa plexiglass) rufite kare 200 nto ya 2.5mm x 2,5mm, ipima 50mm x 25mm, umwanya uwo ari wo wose hejuru yumurimo ugororotse kugirango ugerageze. Reba igipimo cyubuso bwa buri kare kirimo aho bahurira (mubice bya 1/10). Kubara igiteranyo cyibipimo byavuzwe haruguru hanyuma ugabanye na 2 kugirango ubone igipimo cyumwanya uhuza agace kageragejwe.

Icya gatatu, shyigikira umutegetsi ubangikanye hamwe nuburebure buringaniye kumurongo usanzwe ushyigikiwe 2L / 9 uhereye kumpera yumutegetsi. Hitamo ikiraro gikwiye cyo kugerageza ukurikije uburebure bwubutegetsi bukora (muri rusange intambwe 8 kugeza 10, hamwe na hagati ya 50 na 500mm). Noneho, shyira ikiraro kumpera imwe yumutegetsi hanyuma ushireho urumuri cyangwa urwego kuri rwo. Himura ikiraro gahoro gahoro kuva kuruhande rumwe rwumutegetsi ujya kurundi, wimure buri span uva kuri autocollimator ufite impamyabumenyi ya 1 ″ (cyangwa 0.005mm / m) cyangwa urwego rwa elegitoronike ufite impamyabumenyi ya 0.001mm / m (kuburebure bwakazi burenze 500mm, umutegetsi wo mucyiciro cya mbere ufite impamyabumenyi ya 0. Urwego rushobora gukoreshwa hamwe na 0.01mm / m urwego rwa 0.02 2). Itandukaniro riri hagati yisomwa ntarengwa kandi ntarengwa ni ikosa rigororotse ryurwego rwakazi.

IV. Kuringaniza hejuru no hepfo yimirimo ikora, hamwe nubuso bukora hamwe nubutaka bwo hasi, bwurwego rusa. Niba isahani iboneye itabonetse, uruhande rwurwego rushobora gushyirwa hejuru yubufasha hamwe nuburebure bwuburebure bwurwego rwapimwe ukoresheje micrometero ya lever hamwe na 0.002mm cyangwa micrometero hamwe na 0.002mm.
