Hlalutya ngokupheleleyo uQinisekiso lweMetrological lweCMM
I-CMM yinkqubo yokulinganisa eyinkimbinkimbi edibanisa ubuchwepheshe bokubona, boomatshini, bombane, bekhompyutha kunye nolawulo, ngoko ke kukho izinto ezininzi ezingaqinisekanga ezichaphazela iziphumo zokulinganisa, kodwa kwizixhobo zoomatshini ezincinci neziphakathi, ukuphambuka kobushushu obuphakathi ukusuka kubushushu obuqhelekileyo (20℃) yeyona nto iphambili echaphazela ukungaqiniseki kokulinganisa. Ukuze kwenziwe iziphumo ezichanekileyo zokulinganisa i-CMM, ubushushu obuphakathi kufuneka bulawulwe ngokungqongqo ngaphakathi koluhlu lweenkcukacha ze-CMM.
1. Ngaba inkqubo yokufumanisa Umatshini wokulungelelanisa ichaphazela iziphumo zokulinganisa?
Siyazi ukuba xa umatshini wokulinganisa ulinganisa, Iprobe ithumela isignali emva kokunxibelelana nomsebenzi oza kulinganiswa, ize emva koko indawo yokulungelelanisa yeprobe iqokelelwe yinkqubo yokulawula kunye nekhompyutha, ize emva koko kubalwe okufunekayo ukuze kufunyanwe iziphumo zokulinganisa esizifunayo. Okwangoku, uninzi lweeprobe ezidibanisa ezintathu luhlobo lokutshintsha, olunemigaqo yoyilo ekhokelela kwiindawo ezahlukeneyo zokudibanisa utshintsho kwiindawo ezahlukeneyo, nto leyo ebangela iimpazamo zokufumanisa. Impazamo ichaphazela ngokuthe ngqo ukungaqiniseki kweziphumo zokulinganisa ukulungelelanisa. Ngoko ke ufuna ukuba impazamo ibe ncinci kangangoko.
2. Zithini iimpazamo ezingama-21 zee-coordinates ezintathu?
Kukho ii-axes ezintathu zokuhamba, nganye inempazamo enye yokuma kunye neempazamo ezintlanu zejiyometri. Iimpazamo zejiyometri ziquka iimpazamo zokuthe tye kwicala elinye kunye neempazamo ze-angular kwicala elinye. Kukho iimpazamo ezili-18 kwi-axes ezintathu, kunye neempazamo ezingama-21 kwicala elinye phakathi kwe-axes ezintathu.
3. Kufuneka kwenziwe nini ukuze kulinganiswe iimpazamo ezingama-21?
Isiseko, ukuchaneka kunye nokulinganiswa kwee-coordinates ezintathu ziyinkimbinkimbi. Nangona zingadweliswanga kwinkcazo, impazamo yokulinganiswa engama-21 iyimfuneko kwiimeko ezilandelayo: ukwamkelwa kwakhona; Impazamo yokulinganisa ubude Impazamo yesiphumo sokulinganisa; Ii-coordinates emva kokuhamba komatshini; Umatshini wokudibanisa ulungisiwe.
4. Zeziphi izixhobo ezifunekayo ukuze kulinganiswe ii-coordinates?
Imigangatho efunekayo ukuze kulinganiswe ezi coordinates zintathu yile: ubungakanani bebakala elihambelanayo lebhloko yokulinganisa yi-1000mm; i-interferometer yelaser. Inqanaba le-elektroniki; i-Square ruler; ibhola eqhelekileyo, njl.
