Xa iinjineli kunye nee-metrologists zikhetha iqonga legranite elichanekileyo lokulinganisa okufunwayo kunye nemisebenzi yokuhlanganisa, isigqibo sokugqibela sihlala sigxile kwiparameter ebonakala ilula: ubukhulu bayo. Nangona kunjalo, ubukhulu bepleyiti yomphezulu wegranite ingaphezulu kakhulu kunomlinganiselo olula-yinto esisiseko echaza umthamo wayo womthwalo, ukuxhathisa ukungcangcazela, kwaye ekugqibeleni, ukukwazi kwayo ukugcina uzinzo lwexesha elide.
Kwizicelo ezichaneke kakhulu, ubukhulu abukhethwanga nje; lubalo lobunjineli olubalulekileyo olusekwe kwimigangatho esekiweyo kunye nemigaqo engqongqo yokuphambuka koomatshini.
UmGangatho wobuNjineli ongemva koSimiselo sokutyeba
Eyona njongo iphambili yeqonga elichanekileyo kukusebenza njengenqwelomoya ethe tyaba, engashukumiyo. Ke ngoko, ubukhulu bepleyiti yomphezulu wegranite bubalwa ngokuyintloko ukuze kuqinisekiswe ukuba phantsi komthwalo olindelekileyo olindelekileyo, ukucaba kwepleyiti iyonke kuhlala ngokungqongqo kwibakala elichaziweyo lokunyamezela (umzekelo, iBanga AA, A, okanye B).
Olu yilo lwesakhiwo luhambelana nezikhokelo zeshishini elikhokelayo, njenge-ASME B89.3.7 standard. Umgaqo ophambili ekuzimiseleni kobunzima kukunciphisa ukuphambuka okanye ukugoba. Sibala ubukhulu obufunekayo ngokuqwalasela iimpawu zegranite-ngokukodwa i-Young's Modulus ye-Elasticity (umlinganiselo wokuqina) -kunye nobukhulu beplate kunye nomthwalo olindelekileyo.
UMgangatho weGunya loMlayisho
Umgangatho owamkelwe ngokubanzi we-ASME udibanisa ubukhulu ngokuthe ngqo kumthamo wokuthwala umthwalo wepleyiti usebenzisa umda othile wokhuseleko:
Umgaqo wozinzo: Iqonga legraniti kufuneka libe ngqindilili ngokwaneleyo ukuxhasa umthwalo oqhelekileyo opheleleyo osetyenziswa kumbindi wepleyiti, ngaphandle kokuphambukisa ipleyiti ecaleni kwayo nayiphi na idiagonal ngaphezu kwesiqingatha sokunyamezela kwayo ukucaba.
Le mfuno iqinisekisa ukuba ubukhulu bubonelela ngokuqina okuyimfuneko ukufunxa ubunzima obusetyenzisiweyo ngelixa ugcina ukuchaneka kwe-sub-micron. Kwiqonga elikhulu okanye elilayishwe kakhulu, ubukhulu obufunekayo bunyuka ngokumangalisayo ukuchasana nomzuzu wokugoba ophakamileyo.
Ukutyeba: IFactor kaThathu kuZinzo oluchanekileyo
Ubungqingqwa beqonga busebenza njenge-amplifier ethe ngqo yengqibelelo yesakhiwo. Ipleyiti etyebileyo ibonelela ngezibonelelo ezintathu eziphambili, ezidityanisiweyo eziyimfuneko kwi-metrology echanekileyo:
1. ISakhono soMlayisho owomeleziweyo kunye noGcino lwe-Flatness
Ukutyeba kubalulekile ekuxhathiseni umzuzu wokugoba obangelwa zizinto ezinzima, ezinje ngoomatshini abakhulu bokulinganisa ukulungelelanisa (CMMs) okanye izinto ezinzima. Ukukhetha ubukhulu obudlula ubuncinci bemfuno kubonelela ngomda wokhuseleko oxabisekileyo. Esi sixhobo esongezelelweyo sinika iqonga ubunzima obuyimfuneko kunye nesakhiwo sangaphakathi ukusabalalisa umthwalo ngokufanelekileyo, ngaloo ndlela kuncitshiswe ngokumangalisayo ukuphambuka kwepleyiti kunye nokuqinisekisa ukuba ukukhanya okufunekayo komhlaba kugcinwe phezu kobomi bonke beqonga.
2. Ukonyuka koZinzo lweDynamic kunye ne-Vibration Damping
Ilitye elishinyeneyo, elinzima legranite ngokwendalo linobunzima obukhulu, obubaluleke kakhulu ekudambiseni ingxolo yoomatshini kunye ne-acoustic. Iqonga elikhulu linezandiso zendalo ezisezantsi, nto leyo eyenza ukuba ichaphazeleke kakhulu kukungcangcazela kwangaphandle kunye nomsebenzi wenyikima oxhaphakileyo kwiindawo zemizi-mveliso. Oku kuthotywa kwe-passive kubalulekile kuhlolo oluphezulu lwe-high-resolution kunye neenkqubo zokulungelelaniswa kwe-laser apho intshukumo ye-microscopic inokonakalisa inkqubo.
3. Ukuphucula i-Thermal Inertia
Umthamo owongezelelweyo wezinto eziphathekayo unciphisa ukuguquguquka kweqondo lokushisa. Ngelixa i-granite ekumgangatho ophezulu sele iqhayisa nge-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, ubukhulu obukhulu bubonelela nge-inertia ephezulu ye-thermal. Oku kuthintela ukuguquka kobushushu obukhawulezayo, obungafaniyo obunokwenzeka xa oomatshini befudumeza okanye imijikelo ye-air conditioning, iqinisekisa ukuba i-platform yereferensi yejometri ihlala ingaguquguquki kwaye izinzile kwixesha elide lokusebenza.
Kwilizwe lobunjineli obuchanekileyo, ubukhulu beqonga legranite ayisiyonto yokucutha ukonga iindleko, kodwa yinto esisiseko sokwenziwa ngcono, ukuqinisekisa ukuba useto lwakho luzisa iziphumo eziphindiweyo nezinokulandeleka ezifunwa yimveliso yanamhlanje.
