機械零件的檢測與誤差原因分析

摘    要
檢測是對機械零件中包括長度、角度、粗糙度、幾何形狀和相互位置等尺寸的測量。機械零件的檢測極為重要，它是把握產(chǎn)品質量的關鍵環(huán)節(jié)，檢測人員必須在充分準備的基礎上按照程序進行，并要分析誤差的產(chǎn)生原因。
　　
　  機械零件的技術要求很多, 它有幾何形狀、尺寸公差、形位公差、表面粗糙度、材質的化學成份及硬度等。檢測時先從何處著手, 用哪些量具, 采用什么樣的先進方法, 是檢測中技術性很強的一個問題。為了使產(chǎn)品質量信得過, 避免出現(xiàn)錯檢、誤檢和漏檢, 對此檢測人員應遵守程序，做好各方面工作。

關鍵詞  檢測  誤差  原因分析。
 

ABSTRACT
Detection is the point of mechanical parts include the length of the roughness geometry and measurement of the size of each location 。Detection of mechanical components is extremely important，It is the key to grasp the product quality, testing personnel must be fully prepared on the basis of in accordance with the procedures and to analyze the causes of errors。
The technical requirements of many machine parts。It has the geometric shape of form and position tolerance tolerance roughness, chemical composition and hardness。Detection start where to start with that kind of advanced measuring method adopted is to detect a problem in highly technical。In order to make the product quality reliable, to avoid false detection and missed fault inspection, inspectors shall comply with procedures for this work in all fields
Key words   Detect    Error     Analysis
