π尺直径示值误差校准方法的研究

Research on the calibration method of π ruler diameter indication error

该文设计一种在钢卷尺检定台上通过标准钢卷尺和激光干涉仪结合,制作记号点,对π尺示值误差进行校准的方法,该方法简单可靠,可有效提高π尺校准的效率,降低校准成本。

A calibration method for π tape indication error by make marker point on the standard steel tape,combining the standard steel tape and the laser interferometer on the steel measuring tape calibration table is designed.The method is simple and reliable,and can effectively improve the efficiency of π calibration and reduce calibration costs.
