How i can make a cylindrical-conic thread, 50 mm thread, 24mm cylindrical-26 conical ,without changing thread profile ?
Are you asking haw to make a tapered thread?
See attached view.
Hope this helps.
Thanks for your answer , the problem is that the profile it changes the angle when he pass from cylindrical to conical ( its normal because he follow the path, helix ) , I need to have the same profile (angle) at all length . Any ideeas?
If I understand correctly, the thread has a tapered section and a straight section?
With a tapered thread the thread form "V" centerline is perpendicular to the axis centerline.
The transition between the conical section and cylindrical section the thread form maintains the same relation.
