Ukuhlukaniswa Kwezindlela Zokulinganisa ze-CMM
A Umshini Wokulinganisa Ohlanganisiwe (i-CMM) iyithuluzi elisetshenziselwa ukukala ngokunembile i-geometry yento. Ngokwezindlela ezahlukene zokulinganisa, i-CMM ingahlukaniswa ngezigaba ezilandelayo:
1. Xhumana I-Probe ithuluzi lokulinganisa elihlanganisa ukulinganisa (elivame ukusetshenziswa kakhulu);
2. Ithuluzi lokulinganisa elihlanganisiwe elibonakalayo;
3. Ithuluzi lokulinganisa elihlanganisiwe le-laser (elisetshenziswa kakhulu ekulinganisweni komkhiqizo nasekuskeni okukopishwe emuva).
Phakathi kwazo, indlela yokulinganisa ukuxhumana ivame ukusetshenziselwa ukulinganisa imikhiqizo eyenziwe ngomshini, imikhiqizo ecindezelwe, amafilimu ensimbi, njll. Ukuze kuhlaziywe idatha yokucubungula umsebenzi noma kuhlinzekwe ngolwazi lokuqala lomsebenzi wobunjiniyela obubuyela emuva, ngokuvamile kuyadingeka ukuskena amaphuzu edatha ebusweni bomsebenzi ovivinywayo ngokusebenzisa i-coordinate Umshini Wokulinganisa. Umsebenzi wokuskena we-CMM ukusebenzisa uhlelo lwe-DMIS ukuqoqa amaphuzu edatha endaweni ethile ebusweni bento ezolinganiswa, okungaba umugqa, ubuso, ingxenye yengxenye, ijika lengxenye noma umugqa ozungeza ibanga elithile ukusuka emaphethelweni. Into elinganisiwe ibekwa esikhaleni sokulinganisa i-coordinate, indawo yokulinganisa yephuzu ngalinye lokulinganisa entweni elinganisiwe ingatholakala, futhi usayizi wejometri, ukuma kanye nendawo yento elinganisiwe kungabalwa ngokuya ngamanani okuxhumanisa endawo ala maphuzu. Isimiso esiyisisekelo ukuthola indawo yephuzu lendawo ehlukile yento yejometri elinganisiwe ngokusebenzisa ukuxhumanisa kwenzwa yokuthola (iprobe) kanye nokulinganisa ukunyakaza kwe-spatial axis, bese uqedela ukuhlaziya nokufaka amaphuzu alinganisiwe (amaqembu amaphuzu) ngokusebenzisa izibalo ezithile zezibalo, bese ekugcineni ubuyisela i-geometric element elinganisiwe, bese ubala ukuphambuka phakathi kwayo nenani lethiyori (inani elijwayelekile) ngalesi sisekelo. Ngakho-ke qedela ukuhlolwa kwezingxenye ezivivinywayo.
Ukusetshenziswa okufanele kwe-CMM kufanele kunake amaphuzu alandelayo:
(1) Ngaphambi kokulungisa ingxenye yokusebenza, i-probe kufanele ibuyiselwe endaweni eqondile ukuze igcine isikhala esikhulu sendawo yokulungisa; Ukuphakamisa ingxenye yokusebenza kufanele kube bushelelezi, futhi akukwazi ukuthinta noma iyiphi ingxenye yengxenye yokusebenza. I-CMM.
(2) Faka izingxenye ngendlela efanele, futhi uqinisekise ukuthi izidingo ze-isothermal zezingxenye nomshini wokulinganisa ziyahlangatshezwa ngaphambi kokufakwa.
(3) Misa uhlelo olufanele lokuhlanganisa ukuqinisekisa ukuthi uhlelo lokuhlanganisa olwakhiwe luyahlangabezana nezidingo zemidwebo ukuze kuqinisekiswe ukunemba kwedatha elinganisiwe.
(4) Uma uhlelo luqhutshwa ngokuzenzakalelayo, kuyadingeka ukuvimbela ukuphazamiseka phakathi kweprobe kanye ne-workpiece, ngakho-ke kuyadingeka ukunaka ukwandisa iphuzu lokushintshashintsha.
