Mikrometre kelimesinin iki olas\u0131 anlam\u0131 oldu\u011funa dikkat edilmelidir. Bir mikrometre, bir \u00f6l\u00e7\u00fcm arac\u0131 veya tersine, metrenin milyonda birine e\u015fde\u011fer bir uzunluk birimi (ayn\u0131 zamanda mikron olarak da bilinir) olabilir. Ancak bu yaz\u0131da \u00e7ok k\u00fc\u00e7\u00fck uzunluklar\u0131 \u00f6l\u00e7en bir cihaz olarak mikrometre kavram\u0131na odaklanaca\u011f\u0131z. <\/p>\n

<\/span> Mikrometre nedir?<\/span><\/h2>\n

Mikrometre<\/strong> , bir nesnenin boyutunu b\u00fcy\u00fck bir hassasiyetle \u00f6l\u00e7ebilen bir \u00f6l\u00e7\u00fcm cihaz\u0131d\u0131r. Mikrometre, milimetrenin y\u00fczde biri ve binde biri (s\u0131ras\u0131yla 0,01 ve 0,001 mm) mertebesinde boyutlar\u0131n \u00f6l\u00e7\u00fclmesini m\u00fcmk\u00fcn k\u0131lar.<\/p>\n

Mikrometre ayr\u0131ca Palmer vidas\u0131<\/strong> , Palmer g\u00f6stergesi<\/strong> veya k\u0131saca Palmer<\/strong> olarak da bilinir, ancak daha yayg\u0131n terimi mikrometredir.<\/p>\n

M\u00fchendislik alan\u0131nda mikrometre, \u00f6rne\u011fin metal levhalar\u0131n, di\u015flilerin, bir mekanizman\u0131n k\u00fc\u00e7\u00fck par\u00e7alar\u0131n\u0131n vb. kal\u0131nl\u0131\u011f\u0131n\u0131 \u00f6l\u00e7mek i\u00e7in s\u0131kl\u0131kla kullan\u0131l\u0131r. Mikrometreler \u00e7ok kullan\u0131\u015fl\u0131d\u0131r \u00e7\u00fcnk\u00fc di\u011fer \u00f6l\u00e7\u00fcm aletlerine g\u00f6re \u00e7ok daha hassast\u0131rlar.<\/p>\n

Bu nedenle \u00e7ok k\u00fc\u00e7\u00fck uzunluklar\u0131 \u00f6l\u00e7mek i\u00e7in mikrometreler kullan\u0131lmal\u0131d\u0131r; B\u00fcy\u00fck nesneleri \u00f6l\u00e7mek i\u00e7in mikrometre kullan\u0131lamaz.<\/p>\n

\u0130lgin\u00e7 bir \u015fekilde mikrometre ismi Yunancada s\u0131ras\u0131yla k\u00fc\u00e7\u00fck ve \u00f6l\u00e7\u00fc anlam\u0131na gelen micros<\/em> ve metron<\/em> kelimelerinden gelmektedir. <\/p>\n

    1. Mikrometreyi kalibre edin.<\/strong> \u00d6ncelikle mikrometrenin kalibre edildi\u011finden emin olman\u0131z gerekir. Bunu yapmak i\u00e7in, pim dayana\u011fa de\u011fene kadar mandal\u0131 \u00e7evirmeniz gerekir.
