Itekhnoloji yokulinganisa i-granite - ichanekile kwi-micron
I-Granite iyahlangabezana neemfuno zobuchwepheshe bokulinganisa banamhlanje kubunjineli bemishini. Amava ekwenzeni iibhentshi zokulinganisa nokuvavanya kunye noomatshini bokulinganisa abadibeneyo abonise ukuba i-granite ineenzuzo ezahlukeneyo kunezixhobo zemveli. Isizathu sesi silandelayo.
Uphuhliso lwetekhnoloji yokulinganisa kwiminyaka yakutshanje namashumi eminyaka lusachulumancisa nanamhlanje. Ekuqaleni, iindlela ezilula zokulinganisa ezifana neebhodi zokulinganisa, iibhentshi zokulinganisa, iibhentshi zokuvavanya, njl.njl. zazanele, kodwa ngokuhamba kwexesha iimfuno zomgangatho wemveliso kunye nokuthembeka kwenkqubo ziye zanda kakhulu. Ukuchaneka kokulinganisa kuqinisekiswa yijometri esisiseko yephepha elisetyenzisiweyo kunye nokungaqiniseki kokulinganisa kweprobe efanelekileyo. Nangona kunjalo, imisebenzi yokulinganisa iya isiba nzima kwaye itshintshatshintsha, kwaye iziphumo kufuneka zibe zichaneke ngakumbi. Oku kubonisa ukuqala kwe-spatial coordinate metrology.
Ukuchaneka kuthetha ukunciphisa ucalucalulo
Umatshini wokulinganisa we-3D uqulathe inkqubo yokubeka indawo, inkqubo yokulinganisa enesisombululo esiphezulu, izinzwa zokutshintsha okanye zokulinganisa, inkqubo yokuvavanya kunye nesoftware yokulinganisa. Ukuze kufezekiswe ukuchaneka kokulinganisa okuphezulu, ukuphambuka kokulinganisa kufuneka kuncitshiswe.
Impazamo yokulinganisa ngumahluko phakathi kwexabiso eliboniswa sisixhobo sokulinganisa kunye nexabiso lokwenyani lereferensi yobungakanani bejometri (umgangatho wokulinganisa). Impazamo yokulinganisa ubude E0 yoomatshini bokulinganisa banamhlanje (iiCMM) yi-0.3+L/1000µm (uL bubude obulinganisiweyo). Uyilo lwesixhobo sokulinganisa, iprobe, icebo lokulinganisa, umsebenzi kunye nomsebenzisi lunempembelelo ebalulekileyo ekuphambukeni komlinganiselo wobude. Uyilo loomatshini yeyona nto iphambili nehlala ihleli enempembelelo.
Ukusetyenziswa kwegranite kwi-metrology yenye yezinto ezibalulekileyo ezichaphazela uyilo loomatshini bokulinganisa. Igranite sisixhobo esifanelekileyo kwiimfuno zanamhlanje kuba izalisekisa iimfuno ezine ezenza iziphumo zichaneke ngakumbi:
1. Uzinzo oluphezulu oluvela kwindalo
I-Granite lilitye lentaba-mlilo elenziwe ngezinto ezintathu eziphambili: i-quartz, i-feldspar kunye ne-mica, ezenziwe yi-crystallization ye-rock melts kwi-crust.
Emva kweminyaka engamawaka "yokwaluphala", igranite inobume obufanayo kwaye ayinaxinzelelo lwangaphakathi. Umzekelo, ii-impala zineminyaka emalunga ne-1.4 yezigidi ubudala.
I-granite inobunzima obukhulu: 6 kwisikali se-Mohs kunye ne-10 kwisikali sobunzima.
2. Ukumelana nobushushu obuphezulu
Xa kuthelekiswa nezinto zesinyithi, igranite inomlinganiselo ophantsi wokwandiswa (malunga ne-5µm/m*K) kunye nesantya sokwandiswa esiphantsi (umz. intsimbi α = 12µm/m*K).
Ukuqhuba okuphantsi kobushushu begranite (3 W/m*K) kuqinisekisa impendulo ecothayo kutshintsho lobushushu xa kuthelekiswa nentsimbi (42-50 W/m*K).
3. Isiphumo esihle kakhulu sokunciphisa ukungcangcazela
Ngenxa yesakhiwo esifanayo, igranite ayinayo intsalela yoxinzelelo. Oku kunciphisa ukungcangcazela.
4. Isitimela sesikhokelo esidibanisa ezintathu ngocoselelo oluphezulu
I-granite, eyenziwe ngelitye eliqinileyo lendalo, isetyenziswa njengepleyiti yokulinganisa kwaye inokusetyenziswa kakuhle kakhulu ngezixhobo zedayimani, nto leyo ebangela ukuba iindawo zomatshini zibe nobuchule obuphezulu.
Ngokusila ngesandla, ukuchaneka kweereyile zesikhokelo kunokulungiswa ukuya kwinqanaba le-micron.
Ngexesha lokusila, ukuguguleka kwamalungu axhomekeke kumthwalo kunokuqwalaselwa.
Oku kubangela ukuba umphezulu ucinezelwe kakhulu, nto leyo evumela ukusetyenziswa kwezikhokelo zokuthwala umoya. Izikhokelo zokuthwala umoya zichaneke kakhulu ngenxa yomgangatho ophezulu womphezulu kunye nentshukumo yokungachukumisi umngxuma.
ukuququmbela:
Uzinzo oluqhelekileyo, ukumelana nobushushu, ukuxinana kokungcangcazela kunye nokuchaneka kwereyile yesikhokelo ziimpawu ezine eziphambili ezenza igranite ibe yinto efanelekileyo kwiCMM. Igranite isetyenziswa ngakumbi ekwenzeni iibhentshi zokulinganisa nokuvavanya, kunye nakwiiCMM zeebhodi zokulinganisa, iitafile zokulinganisa kunye nezixhobo zokulinganisa. Igranite ikwasetyenziswa nakwamanye amashishini, njengezixhobo zoomatshini, oomatshini be-laser kunye neenkqubo, oomatshini be-micromachining, oomatshini bokuprinta, oomatshini be-optical, i-assembling automation, i-semiconductor processing, njl.njl., ngenxa yokwanda kweemfuno zokuchaneka koomatshini kunye nezixhobo zoomatshini.
