Ibyuma Byuma Nibicuruzwa
Ibicuruzwa
umusumari
Igikorwa cyo kubyaza umusaruro gikubiyemo gushushanya insinga, imitwe ikonje, gukonjesha nibindi bikorwa, mugihe uburyo bwo gukora imisumari bworoshye. Imisumari ikorwa nimashini zidasanzwe.
Ibikoresho fatizo byo gukora imisumari ni icyuma kizunguruka, gikozwe mubyuma bizunguruka. Nyuma yo gushushanya insinga, diametre yinkoni yimisumari irakurwa, hanyuma hakorwa umutwe ukonje kugirango umurizo nu mutwe wumusumari, hanyuma hakorwe uburyo bwo gusya kugirango ubone ibicuruzwa byarangiye. Niba ubuso bwumusumari bugomba gukenerwa amashanyarazi cyangwa kwirabura, izi nzira nazo zirashobora kongerwamo.
Ubwoko, imisumari yumurongo wibyuma, imisumari yicyuma ya sima, imigozi yimbaho, imashini yikubita wenyine, imisumari yo kurasa, imisumari igororotse, imisumari itandukanye.
ibiranga
Imisumari ikorwa mukugaburira insinga zibyibushye, zikomeza mumashini aho insinga ifatirwa hagati yimpfu ebyiri hanyuma igacibwa muburebure bwifuzwa. Icyuma gihagije cyo gukora umutwe cyemerewe kuva ku rupfu ku mpera imwe hanyuma kigahinduka umutwe mu mutwe ukoresheje inkoni ya mashini. Urundi ruhande rwigice cyinsinga rwaciwemo ingingo, nyuma yimisumari isohoka mumashini kandi irashobora koroha (kugirango ikureho impande zitoroshye), isukuye, cyangwa isahani.
Imisumari ikozwe mu nsinga z'ibyuma nk'ibikoresho fatizo kandi bigakorwa n'imashini ikora imisumari. Birakwiye gushyingura imitwe yimisumari mubiti kumisumari yo hasi, imisumari yo mubikoresho, imisumari yibiti, nibindi.
1. Imisumari yumutwe ikoreshwa kenshi mubikorwa byo kubaka imisumari hamwe nagasanduku ko gupakira. Bafite umutwe munini uringaniye kandi byoroshye gukuramo iyo batewe imisumari mu giti.
2. Imisumari ikonjeshejwe, ubuso burasunikwa kandi butambutse, bugaragara neza, kandi nta ngese. Umutwe wumusumari numubiri wimisumari. Zikoreshwa cyane mugukosora umurizo.
3. Imisumari yo kugendera ku mafarasi ikoreshwa mugukosora inshundura zicyuma, insinga zogosha, amakadiri yubatswe, nibindi.
4. Imisumari ya mpandeshatu ni ubwoko bwimisumari idasanzwe ifite imisumari imeze nka mpandeshatu, ikunze kwitwa imisumari. Zikoreshwa cyane mugukosora ibyubaka nka sofa nibikoresho byubuhinzi.
4. Imisumari ya kare, umusumari wa kare ni kare, kandi bikoreshwa cyane cyane mu gutera imisumari ibintu bitoroshye kuzunguruka nyuma yo guhangayika, nko gusana ubwato bwibiti no kubaka ibiraro.
5. Imisumari ya sima ikoreshwa mugutera imisumari mubice bya sima nurukuta rw'amatafari ya sima. Byakozwe mubyuma biciriritse na karubone nziza cyane ya karubone yubatswe kandi ifite imbaraga nubukomezi.
