1) Measurement of Splines

Involute splines are available in several standard pressure angles.

The 30 degree pressure angle spline are the most commonly used pressure angle.

The pressure angle measurement of splines are similar to gears, and splines are generally inspected in the same ways

that external and internal gears are inspected, typically through measurement over or between pins.

Measurement over or between pins is when specific sized wires are placed in between gear teeth across from one another and

the distance between the outside of the wires is then measured with micrometers.

This measurement can also tell you if the gear has the proper gear tooth profile.
