Guiding Curves

Hi

 

Guiding Curves is a major area of investment as a modern way to generate and control finishing toolpath especially when using Multi Axis. if you have not tried it - please do as it will cover more and more use cases. if you did - we are looking for your feedback. i.e.:

  • where did you try it and found it useful
  • where it was lacking capabilities / generated unexpected results
  • Are you missing usage instructions? high level (what is it good for) / low level (how do I control XYZ)

etc. any feedback is welcomeSmiley Happy

Hi,

so, from my point of view guiding curves is an operation

what I have thought about long time ago would be good to exists:

-> patter that you can control its shape / from geometry, other curves

-> spiral, helical patterns / without retract,engage

-> 5axis operation with smart tilting

Good move.

 

At the moment what is not so good in this operation is the time od generating, compared to streamline.

What about on/tanto/contact?

Performance went throgh some major improvements. in recent EAP and 12.0.2 it is much faster than before. 

it is not as fast as streamline especially if the streamline path is generated on the drive (i.e no part or cut area), but it is way more robust.

it always work with Contact / Tanto. on is not planned (as it not really control the finish results)

Ive been using EAP package and this operation has replaced my usage for streamline. This path is more reliable and gives way better toolpath result (IE no funky streamline spiking)

 

Only improvement I look forward to is the addition of interpolate vector for tool axis.

In my testing it hangs up 33% and doesn't generate anything at all. I will test on some different models soon. 

 

 

Edit:  

If i waited a few more minutes, I found it finished generating, but had a lot of gouges. PR 9189494 was created. It seems that when Avoidance is set to "none" that it can still gouge the model. When I used the "Tilt/Retract" or "retract" by itself, it would not gouge. If using  "avoidance > none" verify your path carefully. 

 

  

Dear Customer,

 

Reference: PR Number 9189494

 

Siemens PLM believes that the problem you reported where the documentation for
the VARIABLE_AXIS_GUIDING_CURVES operation is incomplete will be resolved by
code changes made to the release of our product NX version 1847.

Can you please open an IR for the case that hangs? not fun, but we need it to improve..

Will do. I will confirm its not something I am doing wrong 1st though.

 

It would get to 33 out of 100, sometimes 34, then sit for a few minutes. After more than 4-5 min of waiting I usually kill the session.

Glenn - NX 12.0.2 and later in 1847 performance gets way better. if you do not have access to EAP versions and can upload the prt - I can tell you how the system does today. 12.0.2 will be released in less than a month.

Hello, I'm just getting to know the variable guiding curve. Very manageable operation.

Do I have a question:

What the containment loops are?
Will it be a 3 axis operation?
 
Below is the video from the first 5axis guiding curve with fixed axis and avoidance and axis smoothing:

(view in My Videos)

 

Have a nice day
