Nkuko twese tubizi, buri buryo bwo gupima ubukana, bwaba Brinell, Rockwell, Vickers cyangwa igeragezwa rya Leeb igerageza, ifite aho igarukira kandi ntabwo ishobora byose. Kubintu binini, biremereye kandi bidasanzwe bya geometrike nkibintu byerekanwe murugero rukurikira, uburyo bwinshi bwo kwipimisha bukoresha ibizamini bya Leeb byoroshye kugirango bigenzure ubukana bwabo.
Uburyo bwo gupima imbaraga za testi ya Leeb igerageza ifite ibintu byinshi bigira ingaruka kumyizerere yabyo: nka: moderi ya elastique modulus, gukoresha umupira wumupira, gukora hejuru yubukonje bukabije, radiyo igoramye, uburebure bwimbitse bwimbitse, nibindi ugereranije nuburyo bwo gupima static bwa Brinell, Rockwell na Vickers, ikosa ni rinini cyane. Niba gukomera bisaba ubunyangamugayo buhanitse, nigute dushobora guhitamo ikizamini gikomeye?
Ubu bwoko bwibikorwa biremereye mugikorwa cyo gupima ibizamini bisanzwe, mbere yikizamini cyo gupakira no gupakurura ibizamini bikomakomeye, no gupakurura ibizamini bizana umuzigo munini mubikorwa, none twahitamo dute ikizamini gikomeye? Ibikurikira birasaba gukoresha ikoreshwa ryikizamini hamwe nuburyo bwo guterura umutwe kugirango urangize inzira yikizamini cyose. Nkuko bigaragara hano hepfo:
Iki gisubizo cyo kugerageza gukomera kirashobora kumenya igeragezwa rya Rockwell / Vickers hamwe na Brinell kwipimisha ukurikije ibipimo byo gupima ubukana (GB / T 231.1, GB / T 4340.1, ISO6507, ISO6508, ASTM E18, nibindi), kandi byujuje ibizamini bisobanutse neza nibisabwa kugirango umusaruro ukorwe neza.
Umutwe wikizamini cyo guterura ibyuma byikora bifite igenamigambi rihamye, rigabanya ikosa ryatewe na screw hamwe no kuzamura intebe yakazi kugirango bipime neza. Ikibanza cyakazi ni kinini mubunini kandi gishobora kwakira ibihangano binini bipima. Ibipimo bya buto imwe bigabanya cyane ikosa ryikizamini nakazi ka tester, byoroshye kandi byihuse.
