Machine Crash Detection/Simulation w G Code in NX CAM

Solution Partner Creator Solution Partner Creator

Hello NX CAM group,

 

I have a customer with some questions on a module for NX CAM. To break it down as simply as possible, customer has been looking at Vericut for detecting/simulating toolpaths with G code to prevent machine tool crashes/other issues when machining various fixtures etc. 

 

Now they already own the NC Sim add on (NX30434). Is there perhaps another NX CAM module that would be available to them? Would there be something they can add from the CAM kit store?

 

Any help is appreciated, thanks!

FYI-They have requested any NX alternatives to Vericut.

 

Thanks!

The "NX NC Simulation Add-On" you mentioned is the only simulation option that can be added for G-code checking.

IS&V offers the following:

  • internal G-code simulation
  • external G-code simulation
    • with some things to setup, like adding tools with the correct tool numbers
  • material removing
    • including checking of IPW violation with rapid moves
    • checking of cut depths that exceed the flute length

These are the ones that come to mind immediately. What else is the customer seeking?

Is IS&V a seperate module?
Customer is asking for an alternative to Vericut that will simulate G code to predict/detect machine/collision errors. That is the main objective for them here.

If I am not mistaken, in order to use the NC Sim module (NX30434), the customer will need to deploy a Sim Kit? Correct me if I am wrong. 

 

Thank you.

IS&V is the abbreviation for "Integrated Simulation & Verification" and the license you mention is the one to get it as an add-on for any NX CAM bundle.

You also need a machine kit, but you also need this for VERICUT.

The machine kit usually consists of the following:

  • post-processor
  • kinematic model
  • CSE driver

What is the current environment of the customer:

  • does he use NX to create the tool paths?
  • does he use NX to post-process the G-code?
  • does he use any other software for CAM?

It is hard to answer, when there is only a vague outline of what the customer is currently doing.

Stefan,

 

Thank you for that info, I am asking the customer for additional details. My gut is telling that this company already has a machine kit. I will keep you in the loop.

 

Thank you!

Stefan,

Can the customer configure the NC Sim add on module for crash detection?

Stefen,

 

"What is the current environment of the customer"

  • does he use NX to create the tool paths?Yes
  • does he use NX to post-process the G-code?Yes
  • does he use any other software for CAM?No, down the road they may want to simulate machines that are not NX posted, but NX is their only concern for now.

The machine simulation is capable of detecting collision, axis limit violations, gouges, etc.

This can be done with or without the use of material removal from the blank.

To detect collisions, you need to set up collision pairs in the kinematic model of the machine kit through the simulation options from the context menu of the machine tool builder navigator.

If I remember correctly, tool and part collisions are enabled by default starting with NX 12.

There should be some examples showing the capabilities in the MACH\samples folder of the NX installation.

Also see the simulation settings dialog box section of the NX documentation. You may want to read through the entire IS&V section of the NX documentation to get a better overview.

IS&V was introduced in NX 2, we started using it with NX 3 and have since then followed a tremendous overhaul of it.

We also evaluated VERICUT, but found the following advantages of IS&V:

  • integrated into the common software a CAM user mostly uses, aka NX
    • no need to switch software
    • no additional maintenance work
    • no additional training
  • no break of the connection between the design and simulation
    • no export of data to have it disconnected from the original

Starting with CSE it is no longer true that IS&V is not simulating the same file as VERICUT does.

The following is true for VERICUT and IS&V:

  • if a part is corrupted it is rubbish in both applications
    • it must be corrected in both applications
  • if the virtual controller doesn't support all options of the physical machine it must be extended
  • only G-code is simulated

We only use VERICUT to verify the material removal of complex parts, but it should be possible to get rid of VERICUT after we migrated to NX 12, where the enhancements and performance improvements of verify 3D are making the use of VERICUT obsolete.
