How to wrap a curve on cone and make sth like this

How to wrap a curve on cone and make sth like this

(OP)
Hello

I`ve got a problem with wraping a curve on cone. I would like to make cone like in the picture and I`m wondering about the best way to do it. Wrap a curve on cone then sweep a circle along guide ( this wraped curve ) and then substract. Could anybody show me how to do it ?.

RE: How to wrap a curve on cone and make sth like this

try creating a helix and projecting it onto the cone

RE: How to wrap a curve on cone and make sth like this

You do know that you can define a helix with a variable radius that would match the surface of the cone don't you?

Best Regards

What version of NX are you using?

This Example of Hudson's is enough for me but, thanks

I`ve got another question, is it possible to make a "double helix/thread" which could be projected onto cone ?

RE: How to wrap a curve on cone and make sth like this

Here is asimple model of a helix projected onto a cone, you could also add another helix with a differnt start angle to create your douple start. Please excuse the crude model it was done a long time ago.

I`m trying to model with JCBCad method but there are some problems. How to model it to be regular ( double "thread" ). I want to have two grooves which will be one on the end of guide. Can anybody show me the way to do it ?

RE: How to wrap a curve on cone and make sth like this

I have attached yet another solution differing from the others based I what I think are improvements to the sweep and a simplification of the helix pointing out my earlier meaning.

Looking at earlier sweeps I thought that I would have gone to a little more trouble to define and control the section accurately. The only use I've ever had for such a thing was the threaded nut on the inside of a drill chuck. Somebody might relate to that. I used a similar method in an effort to reproduce an accurate thread form.

The other thing I'd mention is the absence of any projection which came about because I have used a helix with a simple linear radius law taking values from the sketch for the first revolve.

I hope that it is relatively easy to analyse the model and understand my method and the intention behind it.

stevethb,

If the grooves have a circular section then why not use a tube feature with zero internal radius and save yourself the trouble of dealing with controlling your sweep feature. In your example it looked to be a round section by the sweep had gone horribly wrong!
