Ibyuma by'inguni, bizwi cyane nka icyuma cy'inguni, ni iby'icyuma cy'ubwubatsi cya karuboni, kikaba ari icyuma cyoroshye gikoreshwa mu bwubatsi, ahanini gikoreshwa mu byuma n'imirongo y'aho bakorera. Gusudira neza, imikorere ya pulasitiki n'imbaraga zimwe na zimwe za mekanike birakenewe mu ikoreshwa. Ibikoresho by'icyuma bidakoreshejwe mu gukora icyuma cy'inguni ni ibikoresho by'icyuma bya karuboni nke, kandi icyuma cy'inguni cyarangiye gitangwa mu buryo bushyushye, busanzwe cyangwa bushyushye.
Ibyuma by'inguni bifite icyuma cy'inguni kingana kandi kitangana. Impande ebyiri z'inguni zingana mu bugari. Ibisobanuro byabyo bigaragazwa muri milimetero z'ubugari bw'uruhande × ubugari bw'uruhande × ubugari bw'uruhande. Nk'urugero "∟ 30 × 30 × 3″, bigaragaza ko ubugari bwa mm 30, mu gihe ubugari bw'icyuma cy'inguni bungana na mm 3. Ishobora kandi gukoresha icyitegererezo, yavuze ko icyitegererezo ari umubare wa santimetero z'ubugari, nk'urugero ∟ 3 # icyitegererezo ntikigaragaza ingano y'ubwoko bumwe bw'ubugari butandukanye bw'inkombe, bityo amasezerano n'izindi nyandiko bizakenera kuzuza inkombe y'icyuma cy'inguni, ubunini bw'inkombe burangiye, kwirinda ko byagaragajwe mu icyitegererezo gusa.
Ibipimo by'icyuma gishyushye gifite uburebure bwa 2#-20#, icyuma gishyushye gishobora gukorwa hakurikijwe ibyo imiterere y'imbaraga zitandukanye ikeneye, gishobora kandi gukoreshwa nk'ihuriro hagati y'ibikoresho. Gikoreshwa cyane mu nyubako zitandukanye n'inyubako z'ubuhanga, nko mu nyubako z'ibiti, ikiraro, umunara wo kohereza ibicuruzwa, imashini ziterura, amato, itanura ry'inganda, umunara wo gusubiza ibintu.
