17) Do a similar construction with an arc going the opposite direction to obtain an additional point on the involute. Step 18: 18) This time you subtract the arc length from the original value. You can also draw a point offset the initial value (13) along the base circle to get the...
There is a good tutorial which shows step by step, how to create an involute gear using parametric modeling in CATIA V5. Refer link http://gtrebaol.free.fr/doc/catia/spur_gear.html The parametric equations and procedure can be very well adopted to Open CASCADE function calls. I have use...
