Imirongo itatu-ihuza, nayo yitwa ibipimo, ni imashini yo gupima ukuri, yitwa CMM.Nigikoresho cyiza cyo gupima neza cyakozwe muri za 1960.Yagaragaye kubera gutunganya neza ibikoresho byimashini zikoresha imashini zikoresha imashini zikoresha imashini za CNC, kimwe no gukenera ibikoresho byapimwe byihuse kandi byizewe byo gutunganya ibice byinshi kandi bigoye.

Kugeza ubu, ibipimo bitatu byahuzabikorwa byakoreshejwe cyane mu nganda zinyuranye nko gukora imashini, inganda z’imodoka, inganda za elegitoroniki, inganda zo mu kirere, n’ibindi, kandi byahindutse ibikoresho byingirakamaro byapimwe byo gupima inganda zigezweho no kugenzura ubuziranenge.Kuri gage zidasanzwe zidasanzwe, ibipimo bitatu-bihuza ni ibikoresho byipimisha byingirakamaro.Nyuma yo kubona ibicuruzwa byabakiriya gushushanya no gushushanya gahunda ya gage yujuje ibyangombwa bisabwa nibicuruzwa kandi umukiriya aranyuzwe, birakenewe.Tangira intambwe yo gutunganya mubyiciro bizakurikiraho, noneho dukeneye gukoresha ibipimo bitatu-byo guhuza ibipimo, kubera ko igikoresho ubwacyo ari kinini cyane, koresha rero kugirango ugerageze ukuri kwa buri gice cya gage yacu, kuri gage ubwayo cyane iremeza neza ibikoresho byacu byo kugenzura.Kurugero, imyanya imwe ya gage, uburinganire hamwe numwirondoro we birimo ibice byimodoka.Twese dushobora kubona ingano nyayo mugushakisha ibipimo bifatika
