Gauge block calibration by means of the interferometry
Original language description
There are using two basic methods for gauge block calibration ? both are described by international standard EN ISO 3650. First of them is for calibration using laser, eventually multi-waves interferometry (interferential method). In this case gauge block (GB) is wrung to the reference plane from the free face of gauge block (gauge length). The second method is based on the comparison of length of calibrated GB with length of reference GB (comparative method). In this case there is used double-sided contact measurement by means of length incremental sensor. This paper deals with interferometry calibration method. Benefit of this method rest in its high accuracy. On the other hand it is time consuming method and there is also wear of gauge blocks. During measurement there was investigated GB surface from the microstructure point of view (microstructural analysis) by inerferometric method. It was proved than interferometric method has a great influence on the GB wear.
