Ekuqaleni kwekhulu le-18, i-micrometer yayisesiteji sokukhiqiza ekuthuthukisweni kwemboni yamathuluzi omshini.I-micrometer isengenye yamathuluzi okulinganisa ukunemba avame kakhulu endaweni yokusebenzela.Yethula kafushane umlando wokuzalwa nokuthuthuka kwe-micrometer.
1. Umzamo wokuqala wokulinganisa ubude ngemicu
Abantu baqale basebenzisa isimiso sentambo ukukala ubude bezinto ngekhulu le-17.Ngo-1638, uW. Gascogine, isazi sezinkanyezi saseYorkshire, eNgilandi, wasebenzisa isimiso sesikulufu ukuze alinganise ibanga lezinkanyezi.Ngo-1693, wasungula umthetho wokulinganisa obizwa ngokuthi "caliper micrometer".
Lena isistimu yokulinganisa ene-screw shaft exhunywe kwisondo lesandla elizungezayo ekugcineni kanye nozipho olunyakazayo ngakolunye uhlangothi.Ukufundwa kokulinganisa kungatholwa ngokubala ukujikeleza kwesondo lesandla nge-bezel yokufunda.Isonto elilodwa lesikali sokufunda lihlukaniswe izingxenye ezilinganayo eziyi-10, futhi ibanga likalwa ngokuhambisa uzipho lokulinganisa, oluqaphela umzamo wokuqala wabantu wokulinganisa ubude ngemicu.
2. I-Watt kanye ne-micrometer yokuqala yedeskithophu
Ikhulu leminyaka ngemva kokuba uGascogine esungule ithuluzi lakhe lokulinganisa, uJames Watt, umsunguli wenjini yesitimu, wasungula i-micrometer yokuqala yedeskithophu ngo-1772. Isici esiyinhloko ekwakhiweni kwayo kwakuwukukhuliswa okusekelwe kuntambo yesikulufu.Umklamo wokuqala omise okwe-U owasetshenziswa uJames Watt kamuva waba indinganiso yama-micrometer.Ngaphandle komlando wakhe wama-micrometer, bekuzophazamiseka lapha.Ingxenye yemishini ye-CNC
3. USir Whitworth waqale wadayisa i-micrometer
Kodwa-ke, ama-micrometer ebhentshi kaJames Watt kanye ne-Mausdlay angowokusebenzisa wona.Awekho amathuluzi okulinganisa anembayo emakethe kuze kube sekupheleni kwekhulu le-19.USir Joseph Whitworth, owasungula intambo edumile ethi "Whitworth", waba umholi ekukhuthazeni ukuthengiswa kwama-micrometer.CNC
4. Ukuzalwa kwe-micrometer yesimanje
Ama-micrometer ajwayelekile esimanje anesakhiwo esimise u-U kanye nokusebenza ngesandla esisodwa.Abakhiqizi abaningi basebenzisa umklamo ojwayelekile wama-micrometer.Lo mklamo ojwayelekile ungalandelelwa emuva ku-1848,
lapho umsunguli ongumFulentshi u-J. Palmer ethola ilungelo lobunikazi elibizwa ngokuthi i-Palmer system.Ama-micrometer esimanje acishe alandele umklamo oyisisekelo wesistimu ye-Palmer, njengesakhiwo esimise u-U, i-casing, umkhono, i-mandrel, ne-anvil yokukala.Umnikelo kaPalmer awunakulinganiswa emlandweni we-micrometer.Ingxenye ye-auto ye-CNC
5. Ukuthuthukiswa nokukhula kwe-micrometer
UBrown & Sharpe we-American B&S Company bavakashele iParis International Exposition eyabanjwa ngo-1867, lapho babona khona i-Palmer micrometer okokuqala futhi bayibuyisela e-United States.UBrown noSharpe bafunde ngokucophelela imakhromitha abayibuyisile eParis, base bengeza izindlela ezimbili kuyo:
umshini ongakwazi ukulawula kangcono i-spindle kanye nedivaysi yokuvala i-spindle.Bakhiqiza i-pocket micrometer ngo-1868 futhi bayifaka emakethe ngonyaka olandelayo.
Kusukela lapho, isidingo sama-micrometers kuma-workshops okwenziwa kwemishini siye sabikezelwa ngokunembile, futhi ama-micrometer afanele izilinganiso ezihlukahlukene asetshenziswe kabanzi ngokuthuthukiswa kwamathuluzi omshini.
