    How to define "Max. True Involute Form Roll Angle" cylinder spur gear

    I need to say sorry to dinjin (Mechanical) and gearcutter (Industrial) ,because I give you wrong number of tooth,the Z2 should be 57,not 58,so the CD=(7.5+28.5+0.5891+0.7318)*0.64=23.885 Thank you very much for your help.
