Lipoleiti tsa bokaholimo ba granite ke lisebelisoa tsa motheo tsa litšupiso ho metrology ea litekanyo. Li sebetsa e le data ea mantlha ea 'mele bakeng sa tlhahlobo, tlhahlobo le ho hokahanya kopano holibaka tsa tlhahiso tse nepahetseng haholoLiindasteri tse kang tsa lifofane, tlhahiso ea li-semiconductor, litsamaiso tsa mahlo, le boenjiniere bo tsoetseng pele ba lisebelisoa tsa mochini li itšetlehile ka meaho ena ho boloka ho nepahala ha jeometri maemong a micrometer le sub-micrometer.

Ho fapana le litafole tsa litšupiso tsa tšepe, granite e fana ka sebopeho sa kristale se tsitsitseng ka tlhaho se nang le khatello e tlase haholo ea ka hare, litšobotsi tse ntle tsa ho thothomela ha thothomelo, le botsitso ba nako e telele ba jeometri. Litšobotsi tsena li etsa hore e be e 'ngoe ea thepa e sebelisoang haholo bakeng sa metheo ea metrology e nepahetseng lefatšeng ka bophara.

Libakeng tse tsoetseng pele tsa tlhahiso, mekhatlo e kang ZHHIMG e sebelisa granite e ntšo e nang le bongata bo phahameng ho hlahisa lipoleiti tsa bokaholimo tse etselitsoeng libaka tsa tekanyo tse tsitsitseng haholo moo ho pheta-pheta le taolo ea ho se tsitse ho leng bohlokoa.

1. Saense ea Lintho tse Hlokahalang ka Morao ho Lipoleiti tsa Bokaholimo ba Granite

Granite ke lefika le nang le mouoane le entsoeng haholo-holo ka quartz, feldspar le mica. Ho tšoaneleha ha lona bakeng sa lits'ebetso tsa boenjiniere bo nepahetseng ha se ka phoso empa ho tsoa litšobotsing tsa lona tsa sebopeho sa micro.

1.1 Sebopeho sa kristale le botsitso

Matrix ea kristale e hokahaneng ea granite e fana ka:

• Matla a phahameng a khatello
• Phetoho e nyane ea elastic tlas'a mojaro
• Khatello e tlase ea masala ha e bapisoa le litšepe tse entsoeng ka tšepe
• Botsitso bo botle ba nako e telele

Ho fapana le tšepe kapa aluminium, granite ha e fetoloe ke mekhahlelo kapa ho fetoha ha polasetiki tlas'a meroalo e tloaelehileng ea metrology, e leng se etsang hore e be e loketseng libaka tsa litšupiso.

1.2 Boitšoaro ba Thermal

Ho tsitsa ha mocheso ke e 'ngoe ea liparamente tsa bohlokoa ka ho fetisisa litsamaisong tsa metrology.

Matlotlo a tloaelehileng a granite e ntšo e nang le bongata bo phahameng:

• Koefficient ea katoloso ea mocheso: ~4–7 × 10⁻⁶ /°C
• Ho hloka mocheso o phahameng
• Ho tsamaisa mocheso ka tlase

Sena se bolela hore di-gradient tsa mocheso di ata butle-butle ka hara thepa, di fokotsa ho sotha ha sebaka nakong ya tshebetso ya ho lekanya.

Ka lehlakoreng le leng, meaho ea tšepe e ka bontša boleng ba katoloso ea mocheso ho fihlela ho 12 × 10⁻⁶ /°C, e leng se etsang hore e se ke ea tsitsa haholo bakeng sa lits'ebetso tsa litšupiso tse nepahetseng.

1.3 Litšobotsi tsa ho Fokotsa Mongobo

Granite e na le tšitiso ea tlhaho ea ho thothomela ka lebaka la motsoako oa eona oa liminerale tse sa tšoaneng. Thepa ena e bohlokoa libakeng tseo:

• Ho thothomela ha mochini ka ntle ho teng
• Mechini ea ho Lekanya e Kopanetsoeng (CMM) ea sebetsa
• Ho etsoa interferometry ea laser

Matla a ho thothomela a qhalakanngwa ka meedi ya ka hare ya dithollo ho ena le ho fetisetswa ho pholletsa le sebopeho.

2. Maemo a Nepahetseng bakeng sa Lipoleiti tsa Bokaholimo ba Granite

Lipoleiti tsa bokaholimo ba granite ha se li-slab tse bataletseng tse sa reroang; li hlahisoa le ho netefatsoa tlas'a maemo a thata a machaba a metrology.

2.1 DIN 876 Standard (Jeremane)

Tekanyetso ea DIN 876 e hlalosa limaraka tsa mamello ea ho batalatsa:

Hangata ho ba le sephara ho hlahlojoa ho sebelisoa maemo a elektroniki, laser interferometry, kapa autocollimators.

2.2 ASME B89 (United States)

ASME B89 e hlalosa:

• Ho latela maemo a naha

E sebelisoa haholo lits'ebetsong tsa tlhahiso ea lifofane le tsa ts'ireletso.

2.3 Mekhoa ea Boleng e Thehiloeng ho ISO 9001 / ISO

Leha ISO 9001 e sa hlalose mamello ea metrology ka kotloloho, e laola:

• Mekhoa ea tsamaiso ea boleng
• Ho latela mokhoa oa ho lekanya
• Litlhoko tsa taolo ea ts'ebetso

Bahlahisi ba sebetsang tlasa meralo ya ISO ba tlameha ho netefatsa hore diketane tsa tlhahlobo di a phetwa le hore di tla ngolwa.

3. Mekhoa ea Boenjiniere ba Bophara le ea ho Lekanya

Ho ba sephara ke parameter e hlalosang poleiti ea bokaholimo. Leha ho le joalo, ho ba sephara ha se tekanyo ea ntlha e le 'ngoe empa ke thepa ea jiometri e nkiloeng.

3.1 Mekhoa ea ho Lekanya

Mekhoa e tloaelehileng e kenyelletsa:

• Maemo a moea a elektroniki (mohlala, litsamaiso tsa WYLER)
• Interferometry ea laser (litsamaiso tsa Renishaw)
• Li-collimator tse iketsang
• Papiso ea mechine e sebelisang mahlakore a otlolohileng a maholo

Mokhoa o mong le o mong o hlahisa menehelo e fapaneng ea ho se tsitse.

3.2 Mehloli ea Liphoso Tekanyong ea Bophara

Batho ba ka sehloohong ba tlatsetsang ho se tsitse:

• Li-gradients tsa mocheso holim'a bokaholimo
• Ho pheta-pheta ha lipatlisiso
• Ho thothomela ho honyenyane ho bakoang ke phallo ea moea
• Phapang ea ts'ebetso ea opereishene
• Ho se tsitse ha ho lekanngoa ha disebediswa

Lilaboratoring tsa maemo a holimo, ho se tsitse ha tekanyo ka botlalo ho ka laoloa ka har'a maemo a sub-micron.

3.3 Boitšoaro ba ho Tsitsisa Nako e Telele

Ho fapana le lipoleiti tsa tšepe, granite ha e bontše:

• Phomolo ea khatello ea maikutlo
• Phetoho ea ho thekesela ha polasetiki
• Ho sotha ho bakoang ke mokhathala

Sena se etsa hore lipoleiti tsa bokaholimo ba granite li lokele lits'ebetso tsa litšupiso tsa nako e telele ntle le ho etsoa hape khafetsa.

4. Litšebeliso tsa Liindasteri tsa Lipoleiti tsa Bokaholimo ba Granite

Lipoleiti tsa bokaholimo ba granite li sebetsa e le likarolo tsa motheo liindastering tse ngata tsa theknoloji e phahameng.

4.1 Mechini e Lekanyang e Kopanetsoeng (CMM)

E sebelisoa e le:

• Lintlha tsa motheo tsa litšupiso
• Sethala sa ho lekanya mochini
• Motheo oa tlhahlobo ea mosebetsi

4.2 Lisebelisoa tsa Semiconductor

Likopo li kenyelletsa:

• Mekhoa ea ho hokahanya li-wafer

5. Granite khahlanong le Lisebelisoa tse ling

Qeto ea bohlokoa ea boenjiniere ke khetho ea thepa bakeng sa litšupiso.

Granite e sebetsa hantle ho feta mekhoa e meng ea tšepe libakeng tsa metrology.

6. Mehopolo ea Tlhahiso ea Liindasteri

Lipoleiti tsa bokaholimo ba granite tse phahameng li hloka libaka tse laoloang tsa tlhahiso:

• Mekhoa ea ho lapa ka nepo
• Ho hohla le ho sila ka mekhahlelo e mengata
• Taolo ea mocheso oa tikoloho (20°C ±1°C e tloaelehileng)
• Mekhahlelo ea ho tsitsisa khatello ea maikutlo

Bahlahisi ba tsoetseng pele ba kang ZHHIMG ba kopanya litsamaiso tse kholo tsa ho sebetsa ka mechine tse khonang ho hlahisa lipoleiti tse fetang limithara tse 'maloa ka bolelele ha ba ntse ba boloka taolo ea ho batalatsa ha micron.

Qetello

Lipoleiti tsa bokaholimo ba granite li ntse li le lejoe la motheo la metrology ea sejoale-joale ea ho nepahala ka lebaka la motsoako oa tsona o ikhethang oa botsitso ba mechini, ho se nke lehlakore ha mocheso, le litšobotsi tsa ho thothomela ha thothomelo. Ha li kopantsoe le ho khomarela ka tieo litekanyetso tsa machaba tse kang DIN 876 le ASME B89, litsamaiso tse thehiloeng ho granite li fana ka motheo oa meralo ea motheo ea tekanyo e tšepahalang, e ka phetoang le e ka lateloang.

Ha ho nepahala ha tlhahiso ho ntse ho tswela pele ho ba le mamello ya nanometer-scale, granite e tla dula e le thepa ya bohlokwa e thusang tikolohong ya lefatshe ya metrology.
