摘要
圆锥尺由碳钢制成,呈锥状,表面刻线,广泛应用于孔径、间隙测量。本文详细介绍了圆锥尺的技术指标要求、校准设备及校准方法等。通过对测得值的测量不确定度进行评定,验证校准方法的可行性。
The conical ruler which is made of carbon steel, is conical and marked on the surface.It is widely used in the measurement of aperture and clearance.In this paper, the technical requirements, calibration equipment and calibration methods of the conical ruler are introduced in detail, and the feasibility of the calibration method is verified by evaluating the uncertainty of the measured values.
