Nyob rau hauv qhov raug tshuaj xyuas ntawm ntsug iav hobbing tshuab, kev tshuaj xyuas ntawm indexing kis tsis raug:
Ua ntej, equip lub tshuab cuab tam nrog indexing hanging log, kho cov indexing saw kom tus naj npawb ntawm indexing hniav yog sib npaug zos rau tus naj npawb ntawm cov hniav z ntawm indexing worm.
Nruab ib tus qauv indexing disc rau ntawm dov cutter spindle thiab nyeem ntawv tsom xam ntawm kab ntawv los txiav txim siab qhov kev sib hloov ntawm tus qauv indexing disc (ie dov cutter spindle).
Nruab ib lub theodolite (los yog kho qhov muag ntsuas ntsuas) ntawm lub workbench, nruab ib lub collimator (piv txwv li collimator) ntawm kev txhawb nqa sab nraum lub tshuab cuab yeej, los yog dai ib txoj kab calibration los ntawm qhov deb los txiav txim qhov kev sib hloov ntawm lub workbench.
Thaum lub dov cutter spindle tig ib zaug, indexing worm iav ntawm lub worktable yuav tsum theoretically tig 360 degree / z. Rau txhua qhov kev sib hloov ntawm cov dov cutter spindle, theodolite yuav rov qab mus rau nws txoj haujlwm qub, thiab lub tswv yim sib hloov ntawm lub rooj ua haujlwm tuaj yeem txiav txim siab raws li kev nyeem ntawv ntawm theodolite.
Xyuas lub worktable rau pem hauv ntej thiab rov qab tig ib zaug. Qhov sib txawv ntawm qhov kev sib hloov qhov kev xav thiab qhov theoretical rotation viewpoint ntawm lub workbench yog qhov indexing kis yuam kev ntawm lub tshuab cuab yeej indexing kis tau tus mob.
