Circular to chordal tooth thickness.
(OP)
What is the equation for converting the circular tooth thickness to chordal tooth thickness. I know it is something simple but I cannot find it or remember what it is.
Thanks for any help.

RE: Circular to chordal tooth thickness.
You have to find the angle that the arc represents
Then take the sin of 1/2 the angle times the pitch
diameter.
RE: Circular to chordal tooth thickness.
ch-add= addendum+(tth^2 / (4xpcd))
ch-th= pcd x sine(90 / teeth)

You have to take the backlash into consideration which is
not in your formula.
