Defining Spiral with Law Curves
Defining Spiral with Law Curves
(OP)
Hi,
Since, I am blocked from various image sites, I will try to spell out my delima.
I have defined 2 points.
One point has a radius of: 4.828, which is my starting point.
The other point has a radius of: 5.084
If a line is drawn connecting the 2 points, this will represent my tappered face or ID bore.
The length between the two points is: 10.24
I believe I need to create a Helix feature with its tangent points along the tappered face & will start & stop at the specified points. I'm not sure which or how to control the variousl law curves that will help define the spirl profile.
After I get my correct Helix profile, I have a groove pattern that I will use as my cut tool, which is at a slight angle.
How do I prevent the cut from thickening as it sweeps around the Helix?
I hope this is sufficient info. for someone out here to assist me.
Thanks again for the assistance.

RE: Defining Spiral with Law Curves
I added a post answering this better to your original post. I have added some images and uploaded them to yousendit.com
I used your dimensions to model the example shown.
