How to determine the bow height tolerance of curved workpieces
The curved workpieces are only marked with the radius and tolerance on the drawing, ie R±Δ. The radius measurement is often carried out on the Wangong display by the bow height method. However, the determination of the bow height tolerance has not been solved very well. Generally, the basic size R given according to the drawing before the measurement is calculated, and the Pythagorean theorem is used to calculate each of the required measurements.
