Imithombo yempazamo engatshintshiyo yeUkulungelelanisa umatshini wokulinganisaikakhulu zibandakanya: impazamo yoMsebenzi wokuLinganisa woLungelelaniso ngokwawo, njengempazamo yendlela ekhokelayo (umgca othe tye, ukujikeleza), ukuguqulwa kwenkqubo yokulungelelanisa ireferensi, impazamo yeprobe, impazamo yobungakanani obuqhelekileyo; impazamo ebangelwa yimiba eyahlukeneyo ehambelana neemeko zokulinganisa, njengempembelelo yendawo yokulinganisa (ubushushu, uthuli, njl.), impembelelo yendlela yokulinganisa kunye nefuthe lezinto ezithile zokungaqiniseki, njl.
Imithombo yempazamo yokulungelelanisa umatshini wokulinganisa intsonkothile kangangokuba kunzima ukuyibhaqa kwaye yahlula enye nganye kwaye iyilungise, kwaye ngokubanzi kuphela loo mithombo yempazamo enempembelelo enkulu ekuchanekeni kolungelelwaniso lomatshini wokulinganisa kunye nalawo kulula ukuwahlula ayalungiswa. Okwangoku, eyona mpazamo iphandiweyo yimpazamo yendlela yokulungelelanisa umatshini wokulinganisa. Uninzi lwee-CMM ezisetyenziswa kuqheliselo lwemveliso zii-CMM ze-orthogonal, kunye ne-CMMs ngokubanzi, impazamo yomatshini ibhekisa ikakhulu kwimpazamo yecandelo lentshukumo, kubandakanya impazamo yokubeka, impazamo yentshukumo yokuthe tye, impazamo yentshukumo ye-angular, kunye nempazamo ye-perpendicularity.
Ukuvavanya ukuchaneka kweukulungelelanisa umatshini wokulinganisaokanye ukuphumeza ukulungiswa kwempazamo, imodeli yempazamo engokwemvelo yomatshini wokulinganisa ulungelelaniso isetyenziswe njengesiseko, apho inkcazo, uhlalutyo, ukuhanjiswa kunye nephutha elipheleleyo lento nganye yephutha kufuneka inikwe. Okubizwa ngokuba yiphutha elipheleleyo, ekuqinisekiseni ukuchaneka kwe-CMM, kubhekisela kwimpazamo edibeneyo ebonisa iimpawu ezichanekileyo ze-CMM, oko kukuthi, ukuchaneka kwesalathisi, ukuphindaphinda ukuphindaphinda, njl.
Uhlalutyo lwempazamo yeMechanism
Iimpawu ze-CMM, isikhokelo sikaloliwe sinciphisa idigri ezintlanu zenkululeko ukuya kwindawo ekhokelwa yiyo, kunye nenkqubo yokulinganisa ilawula iqondo lesithandathu lenkululeko kwicala lokuhamba, ngoko ke indawo ekhokelwayo kwindawo imiselwe ngumzila wesikhokelo kunye nenkqubo yokulinganisa ekuyo.
Phanda uhlalutyo lwempazamo
Kukho iintlobo ezimbini ze-CMM probes: iiprobes zoqhagamshelwano zihlulwe zibe ziindidi ezimbini: ukutshintsha (eyaziwa nangokuthi i-touch-trigger okanye i-dynamic signaling) kunye ne-scanning (eyaziwa nangokuthi i-proportional or static signaling) ngokwesakhiwo sabo. Ukutshintsha iimpazamo zeprobe ezibangelwa yi-switch stroke, probe anisotropy, switch stroke dispersion, seta ngokutsha indawo efileyo, njl. njl.
I-stroke yokutshintsha kwe-probe ye-probe kunye ne-workpiece yoqhagamshelwano kwi-probe yeenwele zokuva, ukuphambuka kweprobe kumgama. Le yimpazamo yenkqubo yophando. I-anisotropy ye-probe kukungahambelani kwe-stroke yokutshintsha kuzo zonke iindlela. Yimpazamo ecwangcisiweyo, kodwa idla ngokuphathwa njengempazamo engacwangciswanga. Ukubola kohambo lokutshintsha kubhekiselele kwiqondo lokusasazwa kohambo lokutshintsha ngexesha lemilinganiselo ephindaphindiweyo. Umlinganiselo wangempela ubalwa njengokutenxa okusemgangathweni kohambo lokutshintsha kwicala elinye.
Ukuseta kwakhona i-deadband ibhekisela kwi-probe intonga yokutenxa kwi-equilibrium position, ukususa amandla angaphandle, intonga kwi-spring force reset, kodwa ngenxa yendima yokukhuhlana, intonga ayinakubuyela kwindawo yokuqala, kukutenxa ukusuka kwindawo yokuqala yi-deadband yokusetha kwakhona.
Impazamo edityanisiweyo ye-CMM
Okubizwa ngokuba yimpazamo edibeneyo edibeneyo ngumahluko phakathi kwexabiso elilinganisiweyo kunye nexabiso lokwenene lomgama we-point-to-point kwindawo yokulinganisa i-CMM, enokuthi ibonakaliswe ngolu hlobo lulandelayo.
Impazamo edityanisiweyo enxulumeneyo = ixabiso lomlinganiselo womgama umgama wexabiso lokwenyani
Ukwamkelwa kwe-quota ye-CMM kunye nokulungelelaniswa kwamaxesha, akuyimfuneko ukwazi ngokuchanekileyo impazamo yenqaku ngalinye kwindawo yokulinganisa, kodwa kuphela ukuchaneka kwe-workpiece yokulinganisa ukulungelelanisa, enokuhlolwa ngempazamo edibeneyo ye-CMM.
Impazamo edibeneyo enxulumeneyo ayibonakalisi ngokuthe ngqo umthombo wephutha kunye nephutha lokugqibela lokulinganisa, kodwa ibonisa kuphela ubungakanani bephutha xa ulinganisa imilinganiselo ehambelana nomgama, kwaye indlela yokulinganisa ilula.
Impazamo yeVector yendawo yeCMM
Impazamo yeVektha yesikhala ibhekisa kwimpazamo yeVektha nakweyiphi na indawo kwisithuba somlinganiselo weCMM. Ingumahluko phakathi kweyiphi na indawo ehleliweyo kwindawo yokulinganisa kwindlela efanelekileyo yokulungelelanisa i-angle-angle kunye nemilinganiselo emithathu ehambelanayo kwindlela yokulungelelanisa eyiyo esekwe yiCMM.
Ngokwethiyori, impazamo yevector yendawo yimpazamo ebanzi yevektha efunyenwe yivector synthesis yazo zonke iimpazamo zaloo ndawo.
Ukuchaneka komlinganiselo we-CMM kufuna kakhulu, kwaye inamalungu amaninzi kunye nesakhiwo esinzima, kunye nezinto ezininzi ezichaphazela impazamo yokulinganisa. Kukho imithombo emine ephambili yeempazamo ezimileyo kumatshini we-multi-axis njenge-CMM ngolu hlobo lulandelayo.
(1) Iimpazamo zejometri ezibangelwa kukuchaneka okulinganiselweyo kwezakhiwo (ezifana nezikhokelo kunye neenkqubo zokulinganisa). Ezi mpazamo zichongwa ngokuchaneka kokwenziwa kwezi nxalenye zesakhiwo kunye nokuchaneka kohlengahlengiso ekufakeni nasekugcinweni.
(2) Iimpazamo ezinxulumene nokuqina okulinganiselweyo kweendawo ze-CMM. Zibangelwa ubukhulu becala ubunzima beendawo ezihambayo. Ezi ziphoso zichongwa ngokuqina kwamacandelo esakhiwo, ubunzima babo kunye nokucwangciswa kwabo.
(3) Iimpazamo ze-Thermal, ezifana nokwandiswa kunye nokugoba kwesikhokelo esibangelwa utshintsho olulodwa lobushushu kunye neqondo lokushisa. Ezi mpazamo zimiselwa yisakhiwo somatshini, iimpawu eziphathekayo kunye nokusasazwa kobushushu be-CMM kwaye ziphenjelelwa yimithombo yobushushu yangaphandle (umz. ubushushu be-ambient) kunye nemithombo yobushushu yangaphakathi (umz. iyunithi yokuqhuba).
(4) iimpazamo zokuphanda kunye nezincedisi, ikakhulu kubandakanywa utshintsho kwiradiyasi yesiphelo sophando olubangelwa kukutshintshwa kweprobe, ukongezwa kwentonga ende, ukongezwa kwezinye izincedisi; impazamo ye-anisotropic xa i-probe ichukumisa umlinganiselo kwiindlela ezahlukeneyo kunye nezikhundla; imposiso ebangelwe kukujikeleziswa kwetafile yesalathisi.
