In general manufacturing external splines is facilitated either by hobbing, rolling, or on a gear shaper, and internal splines. Straighttooth spline geometry sae straighttooth splines usually contain 4,6,10, or 16 splines.
Your splines should be a fillet root, side fit type, because the interface is designed to be radially located by a shoulder on the pump flange, and not by the spline itself. User interface the dialogue windows of wn4 allow even the less experienced pc user to find his way around the program quickly. According to iso 141982 simplified machining easy setup and use on standard 3.
