Defining Spiral with Law Curves

[mycon73]

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.

Jason,

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.
