Since the rack tooth profile is a straight line , so that each point on the tooth profile with the same pressure angle , and equal to the inclination angle of the tooth profile.

this angle is called pressure angle , standard value is 20 °.

either with an addendum line parallel with the same pitch on a straight line and modulus .

parallel to the top line and the tooth thickness of the tooth space width of the straight line is called equal dividing line ( neutral) .

it is calculated the size of the rack baseline .
