Sweeping a tool body?

Sweeping a tool body?

Sweeping a tool body?

(OP)
Hi

I've read here:
http://www.plm.automation.siemens.com/en_us/produc...
that
"A body can now be created by sweeping a tool body, locked in a defined orientation, along a 3D path".

What version of NX support it?
And where can I find that option?

As far as I've seen in NX8.5 and NX9 the sweep option doesn't accept solid bodies but sketches.

regards

RE: Sweeping a tool body?

To the best of my knowledge, it will be a future enhancement to NX9. It may come with the first MR, though I have not seen any official confirmation on that.

RE: Sweeping a tool body?

I have heard at the PLM Europe that it ( then ) is/was planned for 9.0.1

Tomas

RE: Sweeping a tool body?

Is there any list of future planned features?

RE: Sweeping a tool body?

I don't think that you will get this info ,...
The software vendors don't want to reveal what they are working on. ( hm, no manufacturing company want that...)
But, what has been shown at the PLM Europe is the subdivisional modeling, the corner blend and the 4GD design . Maybe some other which I don't remember.
The 4GD is already there in some form starting in 8.5, the other 3 planned for 9.x

Regards,
Tomas

RE: Sweeping a tool body?

9.0.2 is what I've heard.

NX 6.0.5.3
NX 9.0.0.19 MP01
Windows 7 64

RE: Sweeping a tool body?

Yes, the plan is to support this type of feature in NX 9.0.2.x, which should be available later next year.

RE: Sweeping a tool body?

Will it be available for any tool shape or only for tools with symmetric body?

RE: Sweeping a tool body?

While the 'tool' body doesn't actually have to be a 'Revolved' body, the shape must be as if it were. In other words, you could use a plain cylinder or one with blended or chamfered edges.

Here's an image of an example part I created using the prototype for this project (which I no longer have access to). The revovled body was swept along the red spline resulting in the swept body which was then subttracted from the cylinder.

RE: Sweeping a tool body?

I am trying to get the tool to work properly "Swept Volume" in NX9 Which should allow you to sweep a solid about a path. My problem is that I am using a helical path to create a cam slot but I get the error "The tool path must be planar." Is there any way to sweep a solid using a helical path?

RE: Sweeping a tool body?

What you're seeing in NX 9.0, which is not enabled by default, is only a prototype intended for testing only. The official project is now scheduled for NX 10.0, which will be released near the end of this year.

Sweeping a solid won't be available in NX9 ?

NX 6.0.5.3
NX 9.0.1.3
Windows 7 64

RE: Sweeping a tool body?

That is the latest word on this project. More work had to be done that would change the NX part model schema making NX 9.0.x parts incompatible with NX 9.0.0 and NX 9.0.1. Therefore we had no choice but to move it to NX 10.0.

RE: Sweeping a tool body?

NOOOOOOOOOO Please tell me it isn't so. I have been looking forward to this enhancement. Great information John. Thanks

RE: Sweeping a tool body?

Tell me about it. One of our reasons to go with NX9!

RE: Sweeping a tool body?

Thats very unfortunate..like everyone else I was looking forward to this in NX9. Thanks for the info John.

RE: Sweeping a tool body?

When the tool body can be defined by a planar section then it can be done with a program/journal. The attached NX8.5 part is one example. In this case my program uses an input planar spline which was wrapped around a cylinder. Then based on the slot size I created two addition splines with the spline points determined in normal planes to the wrapped spline. A swept solid was then created and subtracted from the cylinder.

RE: Sweeping a tool body?


- The problem is that this kind of geometry cannot be modeled (easily) by planar sections because the "cutting section" between a cutting disc and some revolved shape isn't flat.
The contact is rather S-shaped. This can be seen in the attached image.
The red rectangles shows where the disc will be i contact with the cylinder.

There are complex workarounds.

Tomas

NO 'attached image'????

Yes, these are the types of parts that we are testing with the proposed NX 10.0 functionality.

RE: Sweeping a tool body?

How do we get access to the "prototype" for testing ? Is it an environment variable ?

RE: Sweeping a tool body?

There is no longer anything there to test. It was disabled in the production release of NX 9.0.

RE: Sweeping a tool body?

Hi John,

I was wondering if NX CAM 10 will implement B-rep Stock Update so we can output the cut part to Parasolid model and not tessellated STL model with the above enhancement?

Example of CAM program that support B-rep stock is Pro/NC from PTC and Topsolid from Missler.

Thanks.




RE: Sweeping a tool body?

Someone in the CAM group will have to comment on that, perhaps Mark Rief.

There has been no announcement of this for NX 10.

The internal In Process Workpiece (IPW) representation can be used as is for tool path generation, verification, and simulation. It can also be saved as an NX facet body. What are you looking to do with the stock model that you can not do with a facet body?

We are familiar with "subtracting" the tool path motions to make a real solid. This may work for prismatic parts, but has many issues as the parts become more complex or contoured. Imagine subtracting a contour milling tool path with 500,000 linear moves... It is like 500,000 boolean subtracts.
