Nkuko bizwi, buri buryo bwo gupima ubukana—bwaba bukoresha Brinell, Rockwell, Vickers, cyangwa ibipimo by’ubukana bya Leeb—bufite aho bugarukira kandi nta na kimwe gikoreshwa ku isi yose. Ku bikoresho binini kandi biremereye bifite ingano zitari nziza nk’izigaragara mu ngero ziri hepfo, ibipimo by’ubukana bya Leeb bikoreshwa cyane muri iki gihe mu buryo bwinshi bwo gupima ubukana bwabyo kugira ngo bigenzure ubukana bwabyo.
Igipimo cy’ubukana cya Leeb gikoresha uburyo bwo gupima ubukana bwacyo, kandi hari ibintu byinshi bigira ingaruka ku buziranenge bw’igeragezwa ryacyo ry’ubukana, nk’uburyo ibikoresho bikoreshwa mu gupima ubukana bwabyo, uburyo umupira w’imbere ugenda uhinduka, ubukana bw’ubuso bw’igikoresho, uburebure bw’umurambararo w’ubukana, n’ubujyakuzimu bw’urwego rwo gukomera kw’ubuso. Ugereranyije n’uburyo bwo gupima ubukana bwa Brinell, Rockwell, na Vickers, amakosa yacyo yo gupima ni menshi cyane. None se, niba hakenewe ubuziranenge bwinshi mu gupima ubukana, twahitamo dute igipimo cy’ubukana?
Mu gihe cyo gupima ibikoresho binini kandi biremereye hakoreshejwe ibikoresho bisanzwe bipima ubukana, gupakira ibikoresho mbere yo gupima, gupakira no gupakurura ibikoresho mu gihe cyo gupima ubukana, no gupakurura ibikoresho nyuma yo gupima byose bizazana akazi kenshi mu gikorwa. None se, ni gute twahitamo igikoresho gipima ubukana?
Ibipimo bibiri byo gupima ubukana bifite umutwe uterura birasabwa kugira ngo birangize igikorwa cyose cyo gupima, nk'igipimo cyacu cyo gupima ubukana cya Rockwell cyo kuri interineti HRZ-150GE n'igipimo cyo gupima ubukana cya Rockwell cyo kuri mudasobwa SCR3.0.
Ubu buryo bwo gupima ubukana butuma Rockwell ipima ubukana hakurikijwe amabwiriza mpuzamahanga yo gupima ubukana (nka ISO 6506-1:2014 na ISO 6507-1:2018). Mu buryo nk'ubwo, ku igeragezwa rya Vickers na Brinell, imiterere yo guterura umutwe w'igerageza nayo ishobora gushyirwa mu bikorwa. Hagati aho, yujuje ibisabwa byo gupima neza cyane ibikoresho biremereye no gukora neza.
