Chidule cha njira zisanu ndi zitatu zopangira ulusi zomwe muyenera kudziwa mukamakonza.
.Mawu a Chingerezi ofanana ndi Screw ndi Screw. Tanthauzo la mawuwa lasintha kwambiri m’zaka mazana aposachedwapa. Osachepera mu 1725, amatanthauza "mating".
Kugwiritsiridwa ntchito kwa mfundo ya ulusi kungayambikenso ku chida chonyamulira madzi chozungulira chomwe chinapangidwa ndi katswiri wachi Greek Archimedes mu 220 BC.
M’zaka za m’ma 400 AD, mayiko a ku Mediterranean anayamba kugwiritsa ntchito mfundo ya ma bolts ndi mtedza ku makina osindikizira omwe amagwiritsidwa ntchito popanga vinyo. Panthaŵiyo, ulusi wakunjawo unkakulungidwa ndi chingwe kupita ku cylindrical bar ndiyeno wosemedwa motsatira chizindikirochi, pamene ulusi wamkati kaŵirikaŵiri unkapangidwa mwa kumenya ulusi wakunja ndi chinthu chofewa.
Cha m'ma 1500, muzojambula za chipangizo chopangira ulusi chojambulidwa ndi Leonardo da Vinci wa ku Italy, panali lingaliro logwiritsa ntchito Screw yachikazi ndi zida zosinthira kuti zigwirizane ndi ulusi wokhala ndi mafunde osiyanasiyana. Kuyambira pamenepo, njira yodulira ulusi mwa makina yayambika m’makampani opanga mawotchi ku Ulaya.
Mu 1760, abale a ku Britain J. Wyatt ndi W. Wyatt anapeza chilolezo chodulira zitsulo zamatabwa pogwiritsa ntchito chipangizo china. Mu 1778, British J. Ramsden anapanga chipangizo chodulira ulusi choyendetsedwa ndi giya ya nyongolotsi, yomwe imatha kupanga ulusi wautali molunjika kwambiri. Mu 1797, Mngelezi wina dzina lake H. Maudsley anagwiritsa ntchito Screw yachikazi ndi zida zosinthira kutembenuza ulusi wazitsulo wamitundu yosiyanasiyana pa lathe yake yowongoleredwa, yomwe idayika njira yoyamba yokhotakhota.
M'zaka za m'ma 1820, Maudsley adatulutsa matepi oyambirira ndipo amafa chifukwa cha ulusi.
Kumayambiriro kwa zaka za m'ma 1900, chitukuko cha makampani opanga magalimoto chinalimbikitsanso kukhazikika kwa ulusi ndi chitukuko cha njira zosiyanasiyana zolondola komanso zogwira mtima. Mitundu yosiyanasiyana ya mitu yotsegulira yokha ndi matepi ocheperako okha adapangidwa motsatizana, ndipo mphero ya ulusi idayamba kugwiritsidwa ntchito.
Kumayambiriro kwa zaka za m'ma 1930, ulusi ukupera udawonekera.
Ngakhale ukadaulo wogubuduza ulusi unali wovomerezeka koyambirira kwa zaka za zana la 19, chifukwa cha zovuta kupanga nkhungu, chitukukocho chinatalikitsidwa mpaka Nkhondo Yachiwiri Yapadziko Lonse (1942-1945) chifukwa chofuna kupanga zida ndi chitukuko chaukadaulo wogaya ulusi. Vuto lenileni la kupanga nkhungu lakula mofulumira.Kusintha kwa mtengo wa CNC
Ulusi umagawidwa makamaka mu ulusi wolumikiza ndi ulusi wotumizira.
Njira zapakati zogwirira ntchito zolumikizira ulusi ndikugogoda, kusaka, ulusi, kugudubuza ulusi, kugudubuza ulusi, etc.
Njira zapakati zopangira ulusi wopatsirana ndizovuta komanso zokhotakhota bwino---kupera, mphero ---zozungulira komanso zokhotakhota bwino, ndi zina.
