Imithombo yamaphutha amileUmshini Wokulinganisa Ohlanganisiweikakhulukazi kufaka phakathi: iphutha loMshini Wokulinganisa Ohlanganisayo ngokwawo, njengephutha lendlela yokuqondisa (umugqa oqondile, ukujikeleza), ukuguqulwa kwesistimu yokuhlanganisa okubhekiselwe kuyo, iphutha le-probe, iphutha lenani elijwayelekile; iphutha elibangelwa izici ezahlukahlukene ezihlotshaniswa nezimo zokulinganisa, njengethonya lendawo yokulinganisa (izinga lokushisa, uthuli, njll.), ithonya lendlela yokulinganisa kanye nethonya lezinye izici zokungaqiniseki, njll.
Imithombo yamaphutha yomshini wokulinganisa ohlanganisayo iyinkimbinkimbi kakhulu kangangokuthi kunzima ukuyibona nokuyihlukanisa ngayinye bese uyilungisa, futhi ngokuvamile yileyo mithombo yamaphutha kuphela enethonya elikhulu ekunembileni komshini wokulinganisa ohlanganisayo kanye naleyo elula ukuyihlukanisa elungiswayo. Njengamanje, iphutha elicwaningwe kakhulu yiphutha lomshini wokulinganisa ohlanganisayo. Iningi lama-CMM asetshenziswa ekukhiqizeni ama-CMM esistimu yokulinganisa ehambisanayo, futhi kuma-CMM ajwayelekile, iphutha lomshini libhekisela kakhulu ephutheni lengxenye yokunyakaza eqondile, kufaka phakathi iphutha lokubeka, iphutha lokunyakaza okuqondile, iphutha lokunyakaza kwe-angular, kanye nephutha lokuma.
Ukuhlola ukunemba kwe-umshini wokulinganisa ohlanganisayonoma ukuze kusetshenziswe ukulungiswa kwamaphutha, imodeli yephutha elingokwemvelo lomshini wokulinganisa ohlanganisayo isetshenziswa njengesisekelo, lapho kufanele kunikezwe khona incazelo, ukuhlaziywa, ukudluliselwa kanye nephutha eliphelele lento ngayinye yephutha. Okubizwa ngokuthi iphutha eliphelele, ekuqinisekisweni kokunemba kwama-CMM, kubhekisela ephutheni elihlanganisiwe elibonisa izici zokunemba zama-CMM, okungukuthi, ukunemba kwesibonakaliso, ukunemba kokuphindaphinda, njll.: kubuchwepheshe bokulungisa amaphutha bama-CMM, kubhekisela ephutheni levektha lamaphuzu endawo.
Ukuhlaziywa kwephutha lendlela yokusebenza
Izici zendlela yokusebenza ye-CMM, isitimela esiqondisayo sikhawulela amazinga amahlanu enkululeko engxenyeni eqondiswa yiyo, futhi uhlelo lokulinganisa lulawula izinga lesithupha lenkululeko ohlangothini lokunyakaza, ngakho-ke indawo yengxenye eqondisiwe esikhaleni inqunywa isitimela esiqondisayo kanye nohlelo lokulinganisa olufanele lona.
Ukuhlaziywa kwephutha le-probe
Kunezinhlobo ezimbili zama-probe e-CMM: ama-contact probe ahlukaniswe ngezigaba ezimbili: ukushintsha (okwaziwa nangokuthi i-touch-trigger noma i-dynamic signaling) kanye nokuskena (okwaziwa nangokuthi i-proportional noma i-static signaling) ngokwesakhiwo sawo. Amaphutha okushintshanisa ama-probe abangelwa yi-switch stroke, i-probe anisotropy, i-switch stroke dispersion, i-reset dead zone, njll. Iphutha lokuskena ama-probe elibangelwa yi-force a displacement relationship, i-displacement a displacement relationship, i-cross-coupling interference, njll.
Ukushaywa kweprobe kokuthintana kweprobe kanye nomsebenzi we-workpiece ekuzweni kwezinwele zeprobe, ukuphambuka kweprobe kwebanga. Leli yiphutha lesistimu leprobe. I-anisotropy yeprobe ukungaguquguquki kokushaywa kwe-switching kuzo zonke izinhlangothi. Kuyiphutha elihlelekile, kodwa ngokuvamile liphathwa njengephutha elingahleliwe. Ukuqhekeka kokuhamba kwe-switch kubhekisela ezingeni lokuhlakazeka kokuhamba kwe-switch ngesikhathi sokulinganisa okuphindaphindiwe. Ukulinganisa kwangempela kubalwa njengokuphambuka okujwayelekile kokuhamba kwe-switch ohlangothini olulodwa.
I-Setha kabusha i-deadband ibhekisela ekuphambukeni kwenduku ye-probe kusuka endaweni yokulingana, susa amandla angaphandle, induku entwasahlobo ibuyisela kabusha amandla, kodwa ngenxa yendima yokungqubuzana, induku ayikwazi ukubuyela endaweni yokuqala, kungukuphambuka kusuka endaweni yokuqala kuyi-deadband yokusetha kabusha.
Iphutha elihlanganisiwe elihlobene le-CMM
Iphutha elihlanganisiwe elibizwa ngokuthi i-relative integrated umehluko phakathi kwenani elilinganisiwe kanye nenani langempela lebanga eliqondile endaweni yokulinganisa ye-CMM, elingavezwa ngale ndlela elandelayo.
Iphutha elihlanganisiwe elihlobene = inani lokulinganisa ibanga inani langempela lebanga
Ukuze kwamukelwe isilinganiso se-CMM kanye nokulinganiswa okwenziwa ngezikhathi ezithile, akudingeki ukwazi ngokunembile iphutha lephuzu ngalinye esikhaleni sokulinganisa, kodwa kuphela ukunemba komsebenzi wokulinganisa we-coordinate, ongahlolwa ngephutha elihlanganisiwe elihlobene le-CMM.
Iphutha elihlanganisiwe elihlobene alibonisi ngqo umthombo wephutha kanye nephutha lokugcina lokulinganisa, kodwa libonisa kuphela ubukhulu bephutha lapho kulinganiswa ubukhulu obuhlobene nebanga, futhi indlela yokulinganisa ilula kakhulu.
Iphutha le-vector yesikhala se-CMM
Iphutha levektha yesikhala libhekisela ephutheni levektha kunoma yisiphi isikhathi esikhaleni sokulinganisa se-CMM. Umehluko phakathi kwanoma yiliphi iphuzu eliqondile esikhaleni sokulinganisa ohlelweni oluhle kakhulu lwe-engeli yesokudla kanye nezixhumanisi ezihambisanayo ezintathu ohlelweni lwangempela lwe-coordinate olusungulwe yi-CMM.
Ngokwethiyori, iphutha levektha yesikhala yiphutha eliphelele levektha elitholwe ngokuhlanganiswa kwevektha kwawo wonke amaphutha alelo phuzu lesikhala.
Ukunemba kokulinganisa kwe-CMM kudinga kakhulu, futhi kunezingxenye eziningi nesakhiwo esiyinkimbinkimbi, kanye nezici eziningi ezithinta iphutha lokulinganisa. Kunemithombo emine eyinhloko yamaphutha angaguquki emishinini enezingqimba eziningi njenge-CMM kanje.
(1) Amaphutha ejiyometri abangelwa ukunemba okulinganiselwe kwezingxenye zesakhiwo (njengeziqondiso nezinhlelo zokulinganisa). La maphutha anqunywa ukunemba kokukhiqiza kwalezi zingxenye zesakhiwo kanye nokunemba kokulungiswa kokufakwa nokugcinwa.
(2) Amaphutha ahlobene nokuqina okulinganiselwe kwezingxenye zemishini ye-CMM. Abangelwa kakhulu isisindo sezingxenye ezihambayo. Lawa maphutha anqunywa ukuqina kwezingxenye zesakhiwo, isisindo sazo kanye nokuma kwazo.
(3) Amaphutha okushisa, njengokwanda nokugoba komhlahlandlela okubangelwa ukushintsha kwezinga lokushisa elilodwa kanye nokwehla kwezinga lokushisa. Lawa maphutha anqunywa isakhiwo somshini, izakhiwo zezinto kanye nokusatshalaliswa kwezinga lokushisa le-CMM futhi athonywa imithombo yokushisa yangaphandle (isb. izinga lokushisa elizungezile) kanye nemithombo yokushisa yangaphakathi (isb. iyunithi yokushayela).
(4) amaphutha e-probe kanye ne-accessory, ikakhulukazi afaka phakathi izinguquko erediyasini yokuphela kwe-probe okubangelwa ukushintshwa kwe-probe, ukungezwa kwenduku ende, ukungezwa kwezinye izesekeli; iphutha le-anisotropic lapho i-probe ithinta ukulinganisa ngezindlela ezahlukene kanye nezikhundla; iphutha elibangelwa ukuzungeza kwethebula lokukhomba.
