机械零件的检测与误差原因分析

摘    要
检测是对机械零件中包括长度、角度、粗糙度、几何形状和相互位置等尺寸的测量。机械零件的检测极为重要，它是把握产品质量的关键环节，检测人员必须在充分准备的基础上按照程序进行，并要分析误差的产生原因。
　　
　  机械零件的技术要求很多, 它有几何形状、尺寸公差、形位公差、表面粗糙度、材质的化学成份及硬度等。检测时先从何处着手, 用哪些量具, 采用什么样的先进方法, 是检测中技术性很强的一个问题。为了使产品质量信得过, 避免出现错检、误检和漏检, 对此检测人员应遵守程序，做好各方面工作。

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
