Kwangenkulungwane ye-18, ii-micrometers zangena kwinqanaba lemveliso kuphuhliso lweshishini lesixhobo soomatshini. Ukuza kuthi ga namhlanje, i-micrometer isesinye sezona zixhobo zokulinganisa ezichanekileyo kwiworkshop. Ngoku makhe sibone ukuba i-micrometer yazalwa njani.
Abantu baqala ukusebenzisa umgaqo womsonto ukulinganisa ubude bezinto ngenkulungwane ye-17. Ngowe-1638, uW. Gascogine, isazi ngeenkwenkwezi saseYorkshire, eNgilani, wasebenzisa umgaqo womsonto ukulinganisa umgama weenkwenkwezi. Kamva, ngo-1693, wenza irula yokulinganisa ebizwa ngokuba yi "caliper micrometer".
Le yinkqubo yokulinganisa ene-threaded shaft encanyathiselwe kwi-handwheel ejikelezayo kwelinye icala kunye nemihlathi eshukumayo kwelinye. Ukufundwa komlinganiselo kunokufunyanwa ngokubala ukujikeleza kwevili lesandla kunye nedayila yokufunda. Iveki yokucofa ngokufunda yahlulwe yaziindawo ezili-10 ezilinganayo, kwaye umgama ulinganiswa ngokuhambisa uzipho lokulinganisa, oluqonda umzamo wokuqala wabantu wokulinganisa ubude ngomsonto we-screw.
Izixhobo zokulinganisa ngokuchanekileyo azizange zifumaneke kurhwebo de kwaba sekupheleni kwenkulungwane ye-19. UMhlekazi uJoseph Whitworth, owasungula intambo eyaziwayo "yeWhitworth", waba ngumntu ohamba phambili ekukhuthazeni ukuthengiswa kwee-micrometers. UBrown & Sharpe weNkampani ye-B&S yaseMelika bandwendwele iParis International Exposition eyayibanjelwe kwi-1867, apho babona i-Palmer micrometer okokuqala kwaye bayibuyisela eUnited States. UBrown & Sharpe bafunde ngononophelo imayikhromitha ababebuye nayo eParis kwaye bongeza iindlela ezimbini kuyo: indlela yokulawula ngcono intambo yokusonta kunye nesitshixo sokusonta. Bavelisa i-pocket micrometer ngo-1868 kwaye bayizisa kwintengiso kunyaka olandelayo.
Ukusukela ngoko, imfuneko yee-micrometers kwiiworkshops zokwenziwa koomatshini sele iqikelelwe ngokuchanekileyo, kwaye iimicrometer ezifanelekileyo kwimilinganiselo eyahlukeneyo ziye zasetyenziswa ngokubanzi ngophuhliso lwezixhobo zoomatshini.
