Since an involute curve is ever changing it cant simply be drawn like an arc or something. An involute spline is the same as an involute gear with the same specifications i.e number of teeth,pressure angle, and pitch. Generally speaking a spline is only shallower then a gear. If you want to draw a gear and generate a tool path use a cad-cam program like Bob-Cad or Master-cam. Use the gear program and fill in the blanks using your sample for the major and minor diameter to get the depth. Better yet send it to me and I will hob it for you. |
