1. I-Perpendicularity yecala le-straightedge ngokubhekiselele kwindawo yokusebenza: Beka i-granite straightedge kwi-flat plate. Dlula igeyiji yokudayela, exhotyiswe nge-0.001mm isikali, nge-bar ejikelezayo eqhelekileyo kunye ne-zero kwisikwere esiqhelekileyo. Emva koko, ngokufanayo, beka igeyiji yokudayela kwicala elinye le-straightedge. Ukufundwa kwegeyiji yokucofa yimpazamo ye-perpendicularity yela cala. Ngokufanayo, vavanya impazamo ye-perpendicularity kwelinye icala, kwaye uthathe impazamo enkulu.
2. Umlinganiselo weNdawo yoQhagamshelwano lwe-Parallel Straightedge: Faka i-arhente yokubonisa kwindawo yokusebenza ye-straightedge ukuze ivavanywe. Gcoba umphezulu kwipleyiti yentsimbi etyhidiweyo okanye ulungelelaniswe ngokuchaneka okufanayo ukubonisa iindawo zoqhagamshelo ezahlukileyo kumphezulu wokusebenza. Emva koko, beka i-transparent sheet (efana ne-plexiglass sheet) enezikwere ezincinci ezingama-200 ze-2.5mm x 2.5mm, ukulinganisa i-50mm x 25mm, nakweyiphi na indawo kwindawo yokusebenza ye-straightedge ukuze ihlolwe. Jonga umlinganiselo wendawo yesikwere ngasinye esineendawo zoqhagamshelwano (kwiiyunithi ze-1/10). Bala isambuku sezi reshiyo zingasentla kwaye wahlule ngo-2 ukufumana umlinganiselo wendawo yoqhagamshelwano yendawo evavanyiweyo.
Okwesithathu, xhasa irula ehambelanayo kunye neebhloko ezinobude obulinganayo kumanqaku aqhelekileyo okuxhasa i-2L/9 ukusuka ekupheleni kwerula. Khetha ibhulorho efanelekileyo yokuvavanya esekelwe kubude bomhlaba osebenzayo werula (ngokubanzi 8 ukuya kwi-10 amanyathelo, kunye ne-span phakathi kwe-50 kunye ne-500mm). Emva koko, beka ibhuloho kwelinye icala lomlawuli kwaye ukhusele isibonisi okanye inqanaba kuyo. Hambisa ibhulorho ngokuthe ngcembe ukusuka kwelinye icala lerula ukuya kwelinye, ukuhambisa isithuba ngasinye ukusuka kwi-autocollimator ngokuthweswa isidanga se-1″ (okanye i-0.005mm/m) okanye inqanaba le-elektroniki elinokuphumelela kwe-0.001mm/m (ubude bomsebenzi ongaphezulu kuno-500mm, irula yeKlasi yoku-1 enothweso wesidanga se-0mm/0mm. inqanaba le-coincident (inqanaba lohlobo lwesakhelo kunye nokuphumelela kwe-0.02mm / m ingasetyenziselwa inqanaba le-2 Umahluko phakathi kweyona nto iphezulu kunye neyona nto incinci yokufunda yimpazamo yomgangatho wokusebenza kwinqanaba, impazamo yokuqina inokumiselwa ngokusebenzisa i-50mm okanye i-100mm iplate yebhuloho.
IV. I-parallelism yeendawo zokusebenza eziphezulu kunye nezantsi, kunye nendawo yokusebenza kunye nenkxaso ephantsi, kwinqanaba elihambelanayo. Ukuba i-plate flat efanelekileyo ayifumaneki, icala lenqanaba linokubekwa kwindawo yokuxhasa kunye nokwahlukana kokuphakama kwinqanaba elilinganiswe ngokusebenzisa i-lever micrometer kunye nokuphumelela kwe-0.002mm okanye i-micrometer kunye nokuphumelela kwe-0.002mm.
