N'ihe dị ka narị afọ nke 18, micrometer nọ na ọkwa nke nrụpụta na mmepe nke ụlọ ọrụ igwe.Mikrometer ka bụ otu n'ime ngwaọrụ nlebara anya nke ọma na ogbako a.Na nkenke, webata akụkọ ọmụmụ na mmepe nke micrometer.
1. Mgbalị mbụ iji tụọ ogologo ogologo na eri
Ndị mmadụ buru ụzọ jiri ụkpụrụ nke eriri tụọ ogologo ihe na narị afọ nke 17.Na 1638, W. Gascogine, bụ́ ọkà mmụta mbara igwe na Yorkshire, England, ji ụkpụrụ screw tụọ anya ogologo kpakpando.N'afọ 1693, o chepụtara ụkpụrụ nha nke a na-akpọ "caliper micrometer".
Nke a bụ usoro nlegharị anya nke nwere eriri mkpọ nke ejikọrọ na wheel aka na-atụgharị n'otu nsọtụ yana mkịrị na-ebugharị n'akụkụ nke ọzọ.Enwere ike nweta ọgụgụ nha site n'ịgụ ntughari nke wiilịgharị aka na bezel ọgụgụ.A na-ekewa otu izu nke ọnụ ọgụgụ ọgụgụ n'ime akụkụ 10 hà nhata, a na-atụkwa ebe dị anya site n'ịkwagharị eriri nha, nke na-achọpụta mbọ mbụ mmadụ mere iji jiri eri tụọ ogologo ya.
2. Watt na mbụ desktọọpụ micrometer
Otu narị afọ ka Gascogine rụpụtachara ngwá ọrụ ya, James Watt, bụ́ onye na-emepụta ụgbọ mmiri, chepụtara micrometer mbụ nke desktọpụ na 1772. Ihe bụ isi ihe na-emepụta ya bụ ibuwanye elu dabere na eriri screw.Nhazi nhazi mbụ nke U-nke James Watt ji emecha bụrụ ọkọlọtọ maka micrometers.Enweghị akụkọ ihe mere eme nke micrometers, a ga-akwụsị ya ebe a.CNC machining akụkụ
3. Sir Whitworth bu ụzọ wepụta micrometer
Agbanyeghị, James Watt na Mausdlay's bench micrometer bụ nke ukwuu maka ojiji nke ha.Enweghị ngwa eji atụ ihe ziri ezi n'ahịa ruo n'akụkụ ikpeazụ nke narị afọ nke 19.Sir Joseph Whitworth, onye mepụtara "Whitworth thread" ama ama, ghọrọ onye ndu n'ịkwalite azụmahịa nke micrometers.CNC
4. Ọmụmụ nke micrometer nke oge a
Micrometers ọkọlọtọ ọgbara ọhụrụ nwere usoro U- na ọrụ otu aka.Ọtụtụ ndị na-emepụta ihe na-eji ihe eji eme ihe nke micrometers.Enwere ike ịchọta ụdị ụdị a na 1848.
mgbe onye France na-emepụta ihe bụ J. Palmer nwetara patent a na-akpọ usoro Palmer.Mikrometer nke oge a fọrọ nke nta ka ọ na-agbaso usoro nhazi nke Palmer, dị ka nhazi U-ụdị, mkpuchi, aka uwe, mandrel, na anvil.Onyinye Palmer enweghị atụ na akụkọ ihe mere eme nke micrometer.CNC akpaaka akụkụ
5. Mmepe na uto nke micrometer
Brown & Sharpe nke American B&S Company gara na Paris International ngosi e mere na 1867, ebe ha hụrụ Palmer micrometer maka oge mbụ wee weghachi ya na United States.Brown & Sharpe ji nlezianya mụọ micrometer ha si na Paris lọta, wee tinye usoro abụọ na ya:
usoro nke nwere ike ịchịkwa spindle na ngwaọrụ mkpọchi spindle.Ha mepụtara micrometer akpa na 1868 wee weba ya n'ahịa n'afọ na-esote.
Kemgbe ahụ, a na-ebu amụma n'ụzọ ziri ezi mkpa micrometers na ụlọ ọrụ mmepụta ihe, na micrometers kwesịrị ekwesị maka nha dị iche iche ejiriwo mmepe nke ngwaọrụ igwe.
