Hariho ubwoko bwinshi bwamadosiye yicyuma, harimo dosiye ya fitteri, yabonye dosiye, gushiraho amadosiye, amadosiye yihariye, amadosiye yumukoresha, amadosiye adasanzwe yisaha, hamwe namadosiye yimbaho. Uburyo bwabo bwo gupima ubukana bwubahiriza cyane cyane ISO 234-2: 1982 Amadosiye yicyuma na Rasps - Igice cya 2: Ibiranga gukata.
Ibipimo mpuzamahanga byerekana uburyo bubiri bwo kwipimisha: uburyo bukomeye bwa Rockwell nuburyo bukomeye bwa Vickers.
1. Kuburyo bukomeye bwa Rockwell, igipimo cya Rockwell C (HRC) gikoreshwa muri rusange, kandi ibisabwa gukomera mubisanzwe birenze 62HRC. Iyo ubukana buri hejuru, Rockwell A igipimo (HRA) nacyo gishobora gukoreshwa mugupima, kandi agaciro gakomeye kaboneka muguhindura. Ubukomere bwimikorere ya dosiye (agace kangana na bitatu bya gatanu byuburebure butangirira kumutwe) ntibishobora kuba hejuru ya 38HRC, kandi ubukana bwa dosiye yinkwi ntibushobora kuba munsi ya 20HRC.
2.Ibizamini bya Vickers birashobora kandi gukoreshwa mugupima, kandi agaciro gakomeye kazaboneka binyuze muguhindura nyuma yo kwipimisha. Gukomera kwa Vickers birakwiriye mugupima amadosiye yicyuma afite ibice bito cyangwa nyuma yo kuvura hejuru. Kuri dosiye zicyuma zivuwe nubushyuhe bwo hejuru cyangwa kuvura ubushyuhe bwimiti, ubukana bwazo bugomba kugeragezwa kuri mm 5 kugeza kuri mm 10 uvuye kuri dosiye iheruka gukata.
Ubukomezi bwinyo yinyo igomba kuba hagati ya 55 HRC na 58 HRC, ikwiriye kwipimisha nuburyo bukomeye bwa Vickers. Niba hari umwanya ukwiye, urupapuro rwakazi rushobora gushyirwa kumurongo wakazi wa Vickers gukomera kwipimisha. Nyamara, ibihangano byinshi ntibishobora gupimwa muburyo butaziguye; mubihe nkibi, dukeneye kubanza gutegura ingero zakazi. Icyitegererezo cyo gutegura icyitegererezo gikubiyemo imashini ikata ibyuma, imashini isya & imashini isya, hamwe nicyuma cyerekana ibyuma. Noneho, shyira ingero zateguwe kuri Vickers gukomera kwipimisha akazi kugirango ugerageze.
Twabibutsa ko ikizamini cyo gukomera kwa dosiye gishobora gukorwa gusa mugihe ubuso bwatunganijwe kugirango bwuzuze ibisabwa; usibye ibiteganijwe muri iki gipimo, ikizamini gikomeye cyamadosiye yicyuma nacyo kigomba kubahiriza ibivugwa muri ISO 6508 na ISO 6507-1.
