Imashini zipima ibintu (CMMs) zikoreshwa cyane mu nganda nka za mashini, ikoranabuhanga, ibikoresho, na pulasitiki. CMMs ni uburyo bwiza bwo gupima no kubona amakuru y’ibipimo kuko zishobora gusimbuza ibikoresho byinshi byo gupima ubuso n’ibipimo bihenze, bikagabanya igihe gisabwa ku mirimo igoye yo gupima kuva ku masaha kugeza ku minota—ikintu kidashobora kugerwaho hamwe n’ibindi bikoresho.
Ibintu Bigira Ingaruka ku Mishini zo Gupima: Ibintu Bigira Ingaruka ku Gupima mu CMM. Mu gipimo cy’igihugu, agace k’ubwihangane bwa coaxiality kuri CMM gasobanurwa nk'agace kari mu buso bw’umuzenguruko bufite ubushobozi bwo kwihanganira t na coaxial hamwe n’umurongo wa datum wa CMM. Gifite ibintu bitatu byo kugenzura: 1) umurongo-ku-umurongo; 2) umurongo-ku-umurongo; na 3) hagati-ku-umurongo. Ibintu Bigira Ingaruka ku Gupima mu Bipimo bya 2.5-Dimensional: Ibintu by'ingenzi bigira ingaruka ku gupima mu bipimo bya 2.5-dimensional ni aho hagati n'icyerekezo cy'umurongo w'igice cyapimwe n'igice cya datum, cyane cyane icyerekezo cy'umurongo. Urugero, iyo upima uruziga rubiri rw'igice kuri silinda ya datum, umurongo uhuza ukoreshwa nk'umurongo wa datum.
Inziga ebyiri zifatanye nazo zipimirwa kuri silinda yapimwe, umurongo ugororotse ukorwa, hanyuma hakabarirwa ubugari bw'amazi. Dufashe ko intera iri hagati y'ubuso bubiri bw'imitwaro kuri datum ari 10 mm, kandi intera iri hagati y'ubuso bw'imitwaro ya datum n'igice cy'uruziga rwapimwe ari 100 mm, niba aho hagati h'uruziga rwa kabiri rw'imitwaro rwa datum hari ikosa ryo gupima rya 5um hamwe n'igice cyo hagati cy'uruziga rwa datum, noneho umurongo wa datum uba umaze kuba 50um kure iyo wongerewe ku gice cy'uruziga rwapimwe (5umx100:10). Muri iki gihe, nubwo silinda yapimwe yaba ifatanye na datum, ibisubizo by'ibipimo by'ibipimo bibiri na 2.5 bizakomeza kugira ikosa rya 100um (agaciro kamwe ko kwihanganira ni diameter, na 50um ni radius).
