Analysis and calculation of dimension of gauge block in sine bar measuring taper angle

sine bar, measure, taper angl, dimension of gauge block

The sine bar is a precision measuring tool which is used for indirect measurement or machining of precision angle by the principle of sine function. When the cone taper angle is measured by sine bar, which is at one end of the sine bar need to pad the size of the corresponding block below it, the sine bat will be risen and the angle of lifting is related to the type and the method of the measuring cone. The dimension of gauge block is decided by the angle of lifting and sine function. The error of Block size will directly affect the accuracy of measurement results.
