Mu kunyura ku ntego y'indorerwamo mu buso mu buryo busanzwe no guhuza ingero z'ubuso, imiterere y'uburebure bw'ubuso ishobora kongera kubakwa. Autocollimators zifite ubushobozi bwo kureba mu masegonda 0.01 zitanga ubundi buryo bufatika bwo gupima ubugari bw'ubuso bunini.
Ibipimo: Impamvu ibintu bigenzurwa ari ingenzi
Kimwe mu bintu byirengagizwa cyane mu gupima ubugari bw'aho hejuru ni ukugenzura ibidukikije bikenewe kugira ngo haboneke ibisubizo byemewe. Aho hejuru hakozwe granite si ikintu gikomeye kidakora - ni uburyo bw'ubushyuhe busubiza ubushyuhe buturuka mu bidukikije, buturutse ku gukora ku bindi bintu, ndetse no ku bushyuhe bw'umubiri bw'umuntu ubipimye.
Isahani ya granite ya metero 1 ifite CTE ya 7 × 10⁻⁶ /°C izagukaho mikorometero 7 mu burebure kuri buri zamuka rya 1°C mu bushyuhe. Niba igice kimwe cy'isahani gishyushye kuri 0.5°C kurusha ikindi - urugero, kubera ko impera imwe yegereye aho HVAC isohora umwuka - ubushyuhe buvamo buzahindura ubuso hifashishijwe mikorometero nyinshi, bigapfuka cyangwa bigana amakosa nyayo ya geometrike.
Laboratwari zipima neza cyane zikemura ibi binyuze mu kugenzura ibidukikije mu buryo bukomeye:
- Ubushyuhe bwahagaze kugeza kuri ± 0.1°C cyangwa hejuru yayo hafi ya 20°C (ubushyuhe mpuzamahanga bwo gupima ingano ya ISO 1)
- Ubushuhe bugenzurwa kugira ngo hirindwe ko ubushuhe bushobora kwinjiza cyangwa guhumeka buva ku buso bwa granite
- Gutandukanya imitingito kugira ngo hirindwe ko imitingito yo hasi ihurira mu buryo bwo gupima
- Kubuza gukorana neza hagati y'igice cy'ubuso n'ikintu icyo ari cyo cyose kidahuje ubushyuhe n'icyumba
ASME B89.6.2 isanzwe ivuga by’umwihariko ku miterere y’ibidukikije kugira ngo hakorwe neza kandi igomba kwitabwaho hamwe na B89.3.7 mu gushyiraho ibidukikije bipima.
Imiyoboro irwanya guhindagurika ikikije ikigo gipimisha - yuzuyemo ibikoresho bikwiye byo kugabanya ubushyuhe kandi yagenewe guhagarika ikwirakwira ry'imitingito iterwa n'ubutaka - irushaho kurinda ibidukikije byo gupimisha. Ibikoresho bikora ibipimo by'ingenzi cyane kandi bigaragaza ibyuma biguruka hejuru bidatanga impindura za mekanike ku nyubako yo hasi iyo bikorera.
Gukurikirana Gupima: Urusobe Rugenzura Byose
Icyemezo cy’uko icyuma gipima ibintu gifite agaciro nk’uko umugozi w’igenzura ukoreshwa mu gupima ibintu ukoreshwa mu gupima ibintu. Iki gitekerezo - uburyo gikurikirana ibintu - ni ingenzi muri metrologie igezweho kandi cyanditswe mu bipimo mpuzamahanga nka ISO/IEC 17025, bigenga ubushobozi bwa laboratwari zo gupima no gupima ibintu.
Uburyo bwo gukurikirana ibintu bukora ku buryo bukurikira: icyuma gipima ikirere cyangwa interferometero ya laser ikoreshwa mu gupima plaque y'ubuso igomba kuba yarapimwe hakurikijwe urwego rw'icyitegererezo rufite ubunyangamugayo kurusha igikoresho. Icyo gipimo cy'icyitegererezo kigomba kuba cyarapimwe hakurikijwe urwego rw'icyitegererezo rufite ubunyangamugayo - n'ibindi, binyuze mu muyoboro urangira ku gipimo cy'ibanze gishyigikiwe n'ikigo cy'igihugu gishinzwe ibipimo (NMI), nka PTB mu Budage, NIST muri Leta Zunze Ubumwe za Amerika, NPL mu Bwongereza, cyangwa NIM mu Bushinwa.
Buri sano iri muri uru runigi iranditswe hamwe n’icyemezo cyo gupima kigaragaza ibyapimwe, ibyavuyemo, ibipimo bidasobanutse neza, n’ibipimo ngenderwaho byakoreshejwe. Urunigi rwuzuye rwo gukurikirana ibintu rutuma ibyavuye mu gupima byose - harimo n’icyemezo cy’ubuso bw’ikibaho - bihuzwa, binyuze mu bimenyetso byanditse, n’ibipimo ngenderwaho by’ibanze bigena icyuma gipima n’ibindi bice bya SI.
Ku bagura ibice bya granite n'ibice by'ubuso bitunganye, kwemeza uru ruhererekane rw'ibipimo byo gukurikirana si urwego rw'ubuyobozi - ni ukwemeza tekiniki ko amanota ari ku nyandiko y'impamyabushobozi ahuye n'umutungo nyakuri, upimwe w'igice, byemejwe n'ibikoresho bifite ukuri kwemezwa ubwabyo.
Ingaruka zifatika ku bashushanya ibikoresho n'abahanga mu gutanga amasoko
Gusobanukirwa amahame y’ubugari bigira ingaruka zifatika ku bagena ibice bya granite by’ubuziranenge:
Huza amanota n'ikoreshwa. Icyapa cy'ubuso cya 0 gihagije cyane ku mirimo myinshi yo kugenzura umusaruro. Gusobanura urwego rwa 0 ku ikoreshwa ridasaba ubwo buziranenge byongera ikiguzi hatabayeho kongeramo ubushobozi bwo gupima. Ku rundi ruhande, gushyiraho urwego rwa 1 ku mbonerahamwe y'amakuru ya CMM muri laboratwari yo gupima neza bitera ikosa ryo gupima rijyanye n'uburyo ibintu bikorerwa kuri iyo mashini.
Garagaza neza ibipimo ngenderwaho. "Icyuma cy'ubuso cya granite cya 0" ni ibisobanuro bituzuye niba ibipimo ngenderwaho bikurikizwa bitavuzwe. Isuzuma rya DIN 876 rya 0 na ASME B89 bifite ubushobozi bwo kwihanganira ubugari busa ariko butari bumwe. Ku bijyanye n'urusobe rw'ibicuruzwa mpuzamahanga, buri gihe garagaza ibipimo ngenderwaho by'igihugu cyangwa mpuzamahanga bigenga ibipimo ngenderwaho.
Gusaba inyandiko yuzuye yo gupima. Icyemezo kigomba kugaragaza uburyo bwo gupima bwakoreshejwe, imiterere y’ibidukikije mu gihe cyo gupima, igikoresho cyihariye cyakoreshejwe n’inomero yacyo yo gupima, hamwe n’agaciro kabazwe k’ubugari budafite ishingiro ryo gupima. Icyemezo kivuga gusa ko "cyujuje amanota ya 0" nta makuru afatika kidafite, ntikigaragaza ko gikurikiranwa.
Tekereza igihe cyo gupima. Amasahani yo hejuru ya granite ntabwo ahoraho — ashobora kwangirika ahantu hakoreshwa cyane, kandi ubugari bwabyo bugomba kongera gusuzumwa buri gihe. ASME B89.3.7 itanga ubuyobozi ku gihe cyo kongera gupima hashingiwe ku nshuro yakoreshejwe n'uburemere bw'ibipimo byakozwe.
Umwanzuro: Amahame ngenderwaho nk'urufatiro rw'icyizere
Ibipimo by'ubugari ku masahani y'ubuso ya granite atunganye ni uburyo bwo kwizerana - ururimi ruhuriweho rwemerera umuguzi muri Singapuru n'uruganda rwo mu Budage (cyangwa mu Bushinwa) kumvikana ku cyo ibisobanuro bivuze, uburyo byemejwe, n'uburyo ibipimo bidasobanutse bifite. Gusobanukirwa uru rurimi - amanota, ibipimo, uburyo bwo gupima, n'uruhererekane rw'ibipimo - nibyo bihindura icyemezo cyo gutanga amasoko kuva ku kwizera kugera ku cyemezo cy'ubuhanga gishyigikiwe n'ibimenyetso byanditse.
Ku bijyanye n'ikoreshwa aho gupima neza bigena ubwiza bw'ibicuruzwa, uru rufatiro si amahitamo. Ni ibikorwa remezo bitagaragara aho gukora neza bishingira.
