CAM Simulation Model Verification

CAM Simulation Model Verification

I would like to see a feature implemented in the CAM simulation environment. The simulation removes material from user defined stock around a model body. Currently remaining material is shown as colored stock, and gouges (model violations) are shown as gray/white areas.

 

The complaint I have is that it is difficult to judge the amount of remaining stock. And it is near impossible to judge the depth of a model violation.

 

The feature I would like is an additional verification option to compare the simulated body to the CAM model. And be able to quantify the deviation between the two.

 

In my previous CAM software, Gibbs CAM, I had an option to define a tolerance band. Stock was blue, model was gray, gouges were red. This worked fine, I would adjust the tolerance value and observe the color changes.

 

I would be happy with a similar capability inside Fusion. However I would suggest an improvement. With the above method ANY stock was blue and ANY gouges were red, still making it difficult to gauge magnitude. I would prefer a user defined color gradient.

 

An example would be, run the simulation, switch to verification mode, pick a value for max scale (say 0.015"), compute the result, gouges could show as warm colors like yellow for a -0.002" undercut or red for a -0.010" gouge then stock could show as cool colors like blue and purple. By having the user define a max scale this eliminates issues like huge amounts of stock skewing the gradient.

 

I don't know exactly how this would be implemented but I think it should be fairly straightforward, have the software iteratively swell or shrink the model within the user defined scale then do a Boolean comparison to determine stock and gouges.

 

 

 

I hope that was clear enough, in short I want to see if I forgot to create an operation for any features on the parts I produce.

This feature exists in HSMworks, I would like to see it brought into Fusion 360 as well.

This is something we've been working on adding. The implementation will be the same as stock compare in Inventor HSM. CAM-9078

it should be add, a long time ago 😄

This would be an excellent tool. Surfcam had a reasonably decent verification like the one you describe.

Would be really nice to be able to use the computed simulated stock as a stock selection for the next setup.

ex: "Export stock model" option

You can do this. If someone else knows a better more elegant way then please reply, but my method is as follows...

 

  • Run your simulation for whatever "first operation" you have programmed.
  • Right click on the simulated part.
  • Choose "Stock" and then choose "Save Stock"
  • This will let you save an STL file of your simulated part on your hard drive.
  • You then have to import this model and add it to your file.
  • This is where I wonder if there's a better way to do it, but I then have to scale the STL file and translate it to the correct orientation and size relative to my original part/component.
  • Then lock everything in place and go back to CAM for your next operation.
  • You can now set up the next op to use your STL component as the stock model for any operation.

Holy crap... thank you... The scaling/orientation thing is a bummer but that is hugely helpful.

This is something I'm asked for nearly every time I teach Fusion CAM.

Come on guys, get it in there!

Was about to ask for the same feature, PLEASE! I have no idea how much is left to be milled, would be awesome to have a mode where the 2 models (milling ops and original model) are subtracted and you only see the material left.

Hey @Jon_Bancroft, this made it into the latest update, check it out!

Excellent, I appreciate it!
