Ujongwa njani ukuLuleka kweGranite Straightedge

I-Granite straightedges zizixhobo ezichanekileyo ezisetyenziswa ngokubanzi kumashishini afana nokuveliswa koomatshini, i-metrology, kunye nokuhlanganisana koomatshini. Ukuqinisekisa ukuchaneka kwegranite straightedge kubalulekile ekuqinisekiseni ukuthembeka komlinganiselo kunye nomgangatho wemveliso. Apha ngezantsi kukho iindlela eziqhelekileyo zokujonga ukuthe tye kunye nokunyamezelana kwejometri ehambelanayo yegranite straightedges.

1. I-Perpendicularity yecala elichasene nomphezulu wokuSebenza

Ukujonga i-perpendicularity yamacala e-straightedge:

• Beka i-granite straightedge kwi-plate yomhlaba elinganisiweyo.

• Misa igeyiji yokudayela nge-0.001mm yokuphumelela kwibar engqukuva eqhelekileyo kunye noziro usebenzisa isikwere sereferensi.

• Zisa igeyiji yokudayela ukuba idibane necala elinye le-straightedge ukurekhoda ukutenxa kwe-perpendicularity.

• Phinda kwakhona kwelinye icala kwaye urekhode impazamo enkulu njengexabiso le-perpendicularity.

Oku kuqinisekisa ukuba ubuso becala busisikwere kumphezulu wokusebenza, ukuthintela ukutenxa komlinganiselo ngexesha lezicelo eziphathekayo.

2. Umyinge weNdawo yoQhagamshelwano yeNxibelelwano yeNdawo eDityanisiweyo

Ukuvavanya ukuthe tyaba komphezulu ngokomlinganiselo woqhagamshelwano:

• Faka umaleko omncinci we-ejenti yokubonisa kwindawo yokusebenza ye-straightedge.

• Hlikihla umphezulu ngobunono kwipleyiti yentsimbi etyhidiweyo okanye enye into ethe ngqo elinganayo okanye engaphezulu ngokuchaneka.

• Le nkqubo iya kubonisa iindawo zoqhagamshelwano ezibonakalayo.

• Beka igridi ye-plexiglass ecacileyo (iikwere ezincinci ezingama-200, nganye i-2.5mm × 2.5mm) kwiindawo ezingaqhelekanga kumphezulu.

• Bala umlinganiselo wezikwere eziqulethe iindawo zoqhagamshelwano (kwiiyunithi ze-1/10).

• Umyinge we-avareji ke ubalwa, omele indawo yoqhagamshelwano esebenzayo yendawo yokusebenza.

Le ndlela ibonelela ngovavanyo olubonakalayo kunye nobungakanani bemeko yomphezulu we-straightedge.

3. Ukuthe tye koMphezulu wokuSebenza

Ukulinganisa ukuthe tye:

• Xhasa i-straightedge kumanqaku asemgangathweni abekwe kwi-2L / 9 ukusuka ekupheleni nganye usebenzisa iibhloko ezilinganayo zobude.

• Khetha ibhuloho efanelekileyo yokuvavanya ngokobude bendawo yokusebenza (ngokubanzi amanyathelo angama-8-10, athatha i-50-500mm).

• Khusela i-autocollimator, inqanaba lombane, okanye umgangatho womoya ochanekileyo kwibhulorho.

• Hambisa ibhulorho inyathelo ngenyathelo ukusuka kwelinye icala ukuya kwelinye, urekhoda ufundo kwindawo nganye.

• Umahluko phakathi kwamanani aphezulu kunye nawona mancinci abonisa impazamo yokuqina kwendawo yokusebenza.

Kwimilinganiselo yasekuhlaleni engaphezulu kwe-200mm, ipleyiti yebhulorho emfutshane (50mm okanye 100mm) ingasetyenziselwa ukumisela impazamo yokuma okuthe tye ngesisombululo esiphezulu.

4. Ukuhambelana kokuSebenza kunye neNkxaso yoMphezulu

Ukuhambelana kufuneka kuqinisekiswe phakathi:

• Imiphezulu ephezulu kunye nesezantsi yokusebenza kwe-straightedge.

• Indawo yokusebenza kunye nenkxaso yenkxaso.

Ukuba ipleyiti yesibhengezo esisicaba ayifumaneki:

• Beka icala le-straightedge kwinkxaso ezinzileyo.

• Sebenzisa i-lever-type micrometer okanye i-micrometer echanekileyo kunye nokuphumelela kwe-0.002mm ukulinganisa imilinganiselo yobude kunye nobude.

• Ukutenxa kubonisa impazamo yokunxulunyaniswa.

Ukuqukumbela

Ukujonga ukuchaneka kunye nokuchaneka kwejometri ye-granite straightedges kubalulekile ekugcineni ukulinganisa ukunyaniseka kumashishini achanekileyo. Ngokuqinisekisa i-perpendicularity, umlinganiselo wendawo yoqhagamshelwano, ukuchaneka, kunye nokuhambelana, abasebenzisi banokuqinisekisa ukuba i-granite straightedges yabo ihlangabezana nemigangatho ephezulu yokuchaneka efunekayo kwi-industry kunye ne-laboratory applications.
