If the face angle of the blank is "UP" in other words not in the correct position then this will give a false measurement .
Therefore if face angle is say +0.010" then the chordal addendum would be + 0.010" and teeth would have 0.010" less clearance . . If -0.010" then it would be -0.010" and 0.010" more clearance .
