万能工具显微镜是几何量测量中比较常用的精密仪器,能快速准确测量各种形状复杂的样板、螺纹量规、蜗杆、滚刀等,其长度测量读数可精确到微米,角度测量读数可精确到分,但在测量过程中一些细节的疏忽可导致其准确度大大降低。本人在长期的工作实践中总结出一些经验,供大家参考。 The universal tool microscope is the most commonly used precision instrument in geometric quantity measurement. It can quickly and accurately measure various complicated samples, thread gauge, worm, hob, etc. The length measurement reading can be accurate to micrometer and the angle measurement reading can be accurate to the minute , But negligence of some details in the measurement process can lead to greatly reduced its accuracy. I have summed up some experience in long-term work practice, for your reference.
