Ungakubheka Kanjani Ukuqondile Kwe-Granite Straightedge

Ama-granite straightedges angamathuluzi anembayo asetshenziswa kakhulu ezimbonini ezinjengokukhiqiza umshini, i-metrology, kanye nokuhlanganiswa kwemishini. Ukuqinisekisa ukunemba kwe-granite straightedge kubalulekile ukuze kuqinisekiswe ukuthembeka kokulinganisa kanye nekhwalithi yomkhiqizo. Ngezansi kunezindlela ezijwayelekile zokuhlola ubuqotho kanye nokubekezelelana kwejometri okuhlobene kwama-granite straightedges.

1. Perpendicularity of the Side Against the Working Surface

Ukuhlola i-perpendicularity yezinhlangothi eziqondile:

• Beka i-granite eqondile epuleti elingaphezulu elilinganisiwe.

• Misa igeji yokudayela eneziqu ezingu-0.001mm ngebha eyindilinga evamile futhi uziro usebenzisa isikwele esiyinkomba.

• Letha igeji yokudayela ukuthi ixhumane nohlangothi olulodwa lwe-straightedge ukuze urekhode ukuchezuka kwe-perpendicularity.

• Phinda ngakolunye uhlangothi futhi urekhode iphutha elikhulu njengevelu ye-perpendicularity.

Lokhu kuqinisekisa ukuthi ubuso obuseceleni buyisikwele endaweni yokusebenza, kuvimbela ukuchezuka kokulinganisa ngesikhathi sokusetshenziswa okungokoqobo.

2. Isilinganiso Sendawo Yokuxhumana Ye-Parallel Straightedge

Ukuze uhlole ukucaba kwendawo ngesilinganiso sokuxhumana:

• Faka ungqimba oluncane lwe-ejenti yokubonisa endaweni yokusebenza ye-straightedge.

• Gcoba indawo engaphezulu ngobumnene epuleti eliyisicaba lensimbi eyinsimbi noma enye i-straight elinganayo noma ephakeme ngokunemba.

• Le nqubo izodalula izindawo zokuxhumana ezibonakalayo.

• Beka igridi ye-plexiglass ebonisa ngale (izikwele ezincane ezingu-200, ngasinye esingu-2.5mm × 2.5mm) ezindaweni ezingahleliwe phezulu.

• Bala ingxenye yezikwele eziqukethe izindawo zokuxhumana (ngamayunithi ka-1/10).

• Isilinganiso esimaphakathi sibe sesibalwa, simele indawo yokuxhumana esebenzayo yendawo yokusebenza.

Le ndlela ihlinzeka ngokuhlola okubonwayo nokwamanani esimo sobuso be-straightedge.

3. Ukuqondile Kwendawo Esebenzayo

Ukulinganisa ubuqotho:

• Sekela i-straightedge kumamaki ajwayelekile atholakala ku-2L/9 ukusuka ekugcineni ngakunye usebenzisa amabhulokhi anobude obulinganayo.

• Khetha ibhuloho elifanele lokuhlola ngokuya ngobude bendawo yokusebenza (ngokuvamile izinyathelo eziyisi-8–10, ezihlanganisa ama-50–500mm).

• Vikela i-autocollimator, ileveli kagesi, noma ileveli yomoya enembile ebhulohweni.

• Hambisa ibhuloho ngesinyathelo ukusuka komunye umkhawulo uye kwelinye, urekhoda ukufundwa endaweni ngayinye.

• Umehluko phakathi kwamanani aphezulu kanye nobuncane ubonisa iphutha lokuqondile kwendawo yokusebenza.

Ezilinganisweni zasendaweni ezingaphezu kuka-200mm, ipuleti lebhuloho elifushane (50mm noma 100mm) lingasetshenziswa ukucacisa iphutha lokuqondisa ngokulungiswa okuphezulu.

4. Ukufana Kwezindawo Zokusebenza Nokusekela

Ukufana kufanele kuqinisekiswe phakathi:

• Izindawo zokusebenza eziphezulu neziphansi ze-straightedge.

• Indawo yokusebenza nendawo yokusekela.

Uma i-flat plate eyinkomba ingatholakali:

• Beka uhlangothi lwe-straightedge ekusekelweni okuzinzile.

• Sebenzisa i-micrometer yohlobo lwe-lever noma i-micrometer enembile eneziqu ezingu-0.002mm ukuze ulinganise umehluko wobude ngobude.

• Ukuchezuka kumelela iphutha lokuhambisana.

Isiphetho

Ukuhlola ubuqotho nokunemba kwejometri ye-granite straightedges kubalulekile ekugcineni ubuqotho bokulinganisa ezimbonini ezinembayo. Ngokuqinisekisa i-perpendicularity, isilinganiso sephoyinti lokuxhumana, ubuqotho, nokuhambisana, abasebenzisi bangaqinisekisa ukuthi ama-granite abo aqondile ahlangabezana nezindinganiso zokunemba eziphakeme kakhulu ezidingekayo ezisetshenziswa zezimboni nezaselabhorethri.
