Umugozi w'umugozi ugabanyijemo ubwoko bubiri:

1) uruziga rw'urukiramende rw'umurambararo

2) umugozi w'umugozi utagira aho ubohera.

Umugozi w'urukiramende mu mugozi w'urukiramende ukoreshwa cyane, mu gihe umugozi w'urukiramende ukoreshwa mu buremere bwinshi kandi usaba ubushishozi bwo hagati cyane. Imigozi y'urukiramende ikoreshwa mu mpande zirenga ikoreshwa mu ndege, mu modoka, mu matarakiteri, mu nganda zikora ibikoresho by'imashini, mu mashini z'ubuhinzi no mu bikoresho rusange byo kohereza ibikoresho. Bitewe n'imikorere y'umugozi w'urukiramende ukoresha amenyo menshi, ufite ubushobozi bwo gutwara ibintu byinshi, ntaho ubogamiye neza kandi ufite ubuyobozi bwiza, kandi umuzi w'amenyo magufi ushobora gutuma uburemere bwawo bugabanuka. Byongeye kandi, imbaraga z'umugozi n'aho uhagarara ntabwo bigabanuka cyane, gutunganya ibintu biroroshye, kandi ubushishozi bwinshi bushobora kuboneka binyuze mu gusya.

Imigozi ya spline ya Involute ikoreshwa mu guhuza ireme ryinshi, ubwiza bwo hagati, n'ingano nini. Ibiranga: imiterere y'amenyo ni involute, kandi hari imbaraga za radial ku ryinyo iyo rishyizwemo, ibyo bikaba bishobora kugira uruhare mu gushyira hagati mu buryo bwikora, ku buryo imbaraga kuri buri ryinyo ziba zimwe, zikomeye kandi zimara igihe kirekire, ikoranabuhanga ryo gutunganya amenyo ni rimwe n'iry'ibikoresho, kandi biroroshye kubona ubuziranenge n'ubushobozi bwo guhinduranya amenyo.
