Lapho onjiniyela nama-metrologists bekhetha inkundla yegwadle enembayo yemisebenzi enzima yokulinganisa nemisebenzi yokuhlanganisa, isinqumo sokugcina ngokuvamile sigxile kupharamitha ebonakala ilula: ukujiya kwayo. Kodwa-ke, ubukhulu bepuleti elingaphezulu legwadle lingaphezulu kakhulu kobukhulu obulula—kuyisici esiyisisekelo esibeka umthamo walo womthwalo, ukumelana nokudlidliza, futhi ekugcineni, ikhono lawo lokugcina ukuzinza kobude besikhathi eside.
Kuzinhlelo zokusebenza ezinemba okuphezulu, ukujiya akukhethwa ngokungafanele; kuyisibalo esibalulekile sobunjiniyela esisekelwe kumazinga amisiwe nezimiso eziqinile zokuchezuka kwemishini.
Izinga Lobunjiniyela Ngemuva Kokunqunywa Kokuqina
Injongo eyinhloko yeplathifomu enembayo ukusebenza njengendiza eyisithenjwa eyisicaba, enganyakazi. Ngakho-ke, ukushuba kwepuleti lengaphezulu legwadle kubalwa ngokuyinhloko ukuze kuqinisekiswe ukuthi ngaphansi komthwalo wawo omkhulu olindelwe, ukucaba kwepuleti lilonke kuhlala kungaphakathi kwebanga elishiwo lokubekezelelana (isb, IBanga AA, A, noma B).
Lo mklamo wesakhiwo uthobela imihlahlandlela yemboni ehamba phambili, efana nezinga le-ASME B89.3.7. Umgomo oyinhloko ekunqumeni ukushuba ukunciphisa ukuchezuka noma ukugoba. Sibala ubukhulu obudingekayo ngokucabangela izici zegwadle—ikakhulukazi i-Young's Modulus of Elasticity yayo (isilinganiso sokuqina)—kanye nobukhulu bepuleti kanye nomthwalo olindelekile.
Izinga Legunya Lomthamo Womthwalo
Izinga elamukelwa kabanzi le-ASME lixhumanisa ukujiya ngokuqondile kumthamo wokuthwala umthwalo wepuleti kusetshenziswa imajini ethile yokuphepha:
Umthetho Wokuzinza: Iplatifomu yegwadle kufanele ibe ugqinsi ngokwanele ukusekela isamba somthwalo ovamile osetshenziswa phakathi nendawo yepuleti, ngaphandle kokuphambukisa ipuleti kunoma iyiphi i-diagonal ngaphezu kwengxenye yokubekezelela ukucaba kwayo sekukonke.
Le mfuneko iqinisekisa ukuthi ukujiya kunikeza ukuqina okudingekayo ukuze kuthathwe isisindo esisetshenzisiwe ngenkathi kugcinwa ukunemba kwe-sub-micron. Engxenyekazini enkulu noma elayishwe kakhulu, ukujiya okudingekayo kukhula kakhulu ukuze kumelane nomzuzu wokugoba ophakeme.
Ukujiya: I-Triple Factor in Precision Stability
Ugqinsi lweplathifomu lusebenza njenge-amplifier eqondile yobuqotho bayo besakhiwo. Ipuleti elijiyile lihlinzeka ngezinzuzo ezintathu ezinkulu, ezixhumene ezibalulekile ze-metrology enembile:
1. Umthamo Othuthukisiwe Womthwalo kanye Nokugcinwa Kwe-Flatness
Ubukhulu bubalulekile ukuze umelane nesikhathi sokugoba esibangelwa izinto ezisindayo, njengemishini emikhulu yokukala yokuhlanganisa (ama-CMM) noma izingxenye ezisindayo. Ukukhetha ukujiya okudlula imfuneko encane kunikeza umkhawulo wokuphepha obaluleke kakhulu. Lokhu okubalulekile okungeziwe kunikeza inkundla ubukhulu obudingekayo kanye nesakhiwo sangaphakathi ukuze kusabalalise umthwalo ngempumelelo, ngaleyo ndlela kunciphisa ngokuphawulekayo ukuchezuka kwepuleti futhi kuqinisekiswe ukuthi ukucaba kwendawo okudingekile kugcinwa kuyo yonke impilo yesikhulumi.
2. Ukuqina Kwe-Dynamic kanye Nokunciphisa Ukudlidliza
Itshe legwadle elijiyile, elisindayo ngokwendalo linesisindo esikhulu, esibalulekile ekudambiseni umsindo wemishini kanye ne-acoustic. Inkundla enkulu inemvamisa yemvelo ephansi, okuyenza ingangenwa kalula ukudlidliza kwangaphandle kanye nomsebenzi wokuzamazama komhlaba ovamile ezindaweni zezimboni. Lokhu kuthambisa okungenzi lutho kubalulekile ekuhlolweni kokubona okuphezulu nokuqondanisa kwe-laser lapho ngisho nokunyakaza kwe-microscopic kungonakalisa inqubo.
3. Ukuthuthukisa I-Thermal Inertia
Umthamo owengeziwe wezinto ezibonakalayo ubambezela ukushintsha kwezinga lokushisa. Nakuba i-granite yekhwalithi ephezulu isivele ine-coefficient ephansi kakhulu yokwanda okushisayo, ukujiya okukhulu kunikeza inertia ephakeme yokushisa. Lokhu kuvimbela ukuwohloka kwe-thermal okusheshayo, okungajwayelekile okungase kwenzeke lapho imishini ishisa noma imijikelezo ye-air conditioning, iqinisekisa ukuthi i-geometry yesithenjwa yeplathifomu ihlala ingashintshile futhi izinzile ezikhathini ezinde zokusebenza.
Emhlabeni wobunjiniyela obunembayo, ukujiya kweplathifomu yegwadle akuyona into yokunciphisa ukonga izindleko, kodwa isisekelo sesakhiwo sokuthuthukisa, uqinisekisa ukuthi ukusetha kwakho kuletha imiphumela ephindaphindwayo nelandelekayo edingwa ukwenziwa kwesimanjemanje.
