Amanyathelo okukhetha oomatshini abathathu abalinganisayo
1. Uluhlu lokulinganisa
Le yeyona nto iphambili ekukhetheni i-CMM. Xa siceba ukuthenga i-CMM umatshini wokulinganisa olungelelanisiweyo (i-CMM), kufuneka siqale sazi ubungakanani obujikelezileyo bemveliso, size emva koko sikhethe ubungakanani beCMM. Umzekelo, xa ukhetha i-bridge coordinate Umatshini wokulinganisa, ixabiso lezixhobo lihambelana nobubanzi bemitha, ngoko ke kufuneka sihlangabezane noluhlu lokulinganisa kuphela, singalandeli uluhlu olukhulu olungafunekiyo. Ukuba isixhobo somsebenzi esiza kulinganiswa siyinxalenye nje yemveliso yonke, kuya kufuneka ukhethe umatshini wokulinganisa odibeneyo onokubeka isixhobo somsebenzi sonke etafileni, ngelixa ucinga ngobunzima bemveliso, ungadluli umda wokuthwala womatshini wokulinganisa odibeneyo. Inkqubo yeprobe ekhethiweyo ikwachaphazela uluhlu lokulinganisa, njengoko iprobe ithatha indawo ethile yokulinganisa.
2. Ukukhetha iProbe
1) I-Rotary probe: isetyenziselwa kakhulu ukuvelisa i-CMM
2) Iprobe ezinzileyo: isetyenziselwa ikakhulu oomatshini bokulinganisa abalungelelanisiweyo
Akukho mpazamo yokujikeleza ngexesha lokujikeleza. Ngenxa yokuba iprobe ejikelezayo isebenza ngokwahlukileyo kwiprobe engashukumiyo, kukho umahluko kuluhlu lokulinganisa xa ukhetha isixhobo: iprobe ejikelezayo ifuna uluhlu olukhulu lokulinganisa. Kwinto efanayo yokusebenza, iprobe ejikelezayo iya kuhlala kwindawo ethile ngexesha lenkqubo yokujikeleza. Ngokwamava ethu asebenzayo, ekukhetheni umatshini wokulinganisa odibeneyo, ukuba kusetyenziswa iprobe ejikelezayo, kufuneka kuqwalaselwe uluhlu lomatshini wokulinganisa odibeneyo.
Umatshini wokulinganisa odibeneyo (i-CMM) sisixhobo sokulinganisa ukulinganisa ubungakanani bejometri kunye nempazamo yendawo yokusebenza. Xa ukhetha umatshini wokulinganisa odibeneyo, singathelekisa ukuchaneka kokulinganisa kwesixhobo somsebenzi esiza kulinganiswa nokuchaneka komatshini wokulinganisa. Uthelekiso oluchanekileyo asiyonkqubo yokuthelekisa elula. Kwinkcazo yobugcisa yomatshini wokulinganisa, iintlobo ezimbini zeefomyula zokubala ezingaqinisekanga zobude be-axis enye kunye nomlinganiselo wendawo ngokubanzi zinikwa, kwaye ukuchaneka kokulinganisa okuphindaphindiweyo nako kunikwe. Xa kulinganiswa, ukungaqiniseki kokulinganisa kweparameter elinganisiweyo kunqunyelwe kuluhlu oluthile. Ngokubanzi, amanqaku amaninzi okulinganisa kufuneka alinganiswe. Xa kulinganiswa ukunyamezelana kwesimo, inani elikhulu lamanqaku okulinganisa liyabandakanyeka, nto leyo eya kubangela iimpazamo.
Ngamafutshane, abasebenzisi kufuneka bakhethe umatshini wokulinganisa olungelelanisiweyo onobuchane obuphezulu kancinci (kubandakanya ukuchaneka okuphindaphindiweyo). Oku akubangelwa nje bubunzima bomsebenzi wokulinganisa, impazamo yendawo yokulinganisa engenisiweyo inokuba nkulu kunokuba bekulindelwe (ngokutshintsha intloko yokulinganisa okanye ukwandisa intonga yokwandisa kuya kwazisa impazamo enkulu yokulinganisa), kodwa nangokwanda kwenani lokusetyenziswa, ukuchaneka komatshini wokulinganisa kuya kuncipha.
Ukususela kwimo yokusebenza yeprobe ukuya ekuchanekeni kweziphumo zokulinganisa, kukho iiprobe zokudibanisa, iiprobe zokuskena uqhagamshelwano kunye neeprobe ze-optical ezingezizo ezonxibelelwano. Xa ukhetha iprobe, isantya sokulinganisa kunye nokuphindaphinda kweprobe yesixhobo kukhethwa ngokweemfuno zokulinganisa.
Isikali sokufaka i-grating sisisiseko sokufunda se-CMM, ngoko ke i-coefficient yayo yokwandisa ubushushu kufuneka ibe sezantsi kangangoko ukuqinisekisa ukuchaneka kokufunda. Ngoku uphuhliso lwezinto ze-grating ruler lukwagxile ekunciphiseni i-coefficient yokwandisa ubushushu. Oomatshini bokulinganisa bahlulwe ngokwezandla (okanye eziphathwayo) kunye ne-CNC (ulawulo oluzenzekelayo). Ekukhetheni, ubungakanani bento yovavanyo kufuneka bulinganiswe ngokwemiba yobukhulu bebhetshi, inqanaba lokuzenzekelayo, inqanaba lesakhono somsebenzisi kunye notyalo-mali lwemali. Kakade ke, i Umatshini wokulinganisa weCnc inobunono obuphezulu kunye nesantya sokulinganisa esikhawulezayo, kodwa ixesha lokulungiselela ngaphambi kokulinganisa lide kakhulu, iimfuno zobugcisa ziphezulu kakhulu, kwaye utyalo-mali olukhulu kakhulu.
