To calculate the gage blocks height needed to set-up a sine bar to a specific angle
all you have to do is take the SIN of the angle and multiply it by the sine bar length.
The length of the sine bar is the distance between the centers of the sine bar gage
Example: You need to set a 5.0” sine bar or sine plate to 37°
Seen below is the Sine Bar Calculator included within the Web Machinist software
program below. The calculator not only will calculate the gage blocks height needed
but also lists the individual gage blocks needed to obtain the gage blocks height.
Also it can calculate the angle based on the height of the gage blocks used. Very
useful and a real time saver!
