Real Time Simulation

often it is good to see the simulation in real time mode, to be confident with the feed and speed parameters. Or maybe I didn't realize that one can set that when running simulation.

Also it would be good to see the spindle rotation speed simulated, when one set constant speed surface.

@NismoGT 

100% disagree with you.  Its basic math 101 elementary school level.  The program knows the speed and feed.  The program knows the FPS of the PC.  It is EASY to calculate a 1:1 simulation based on feedrate and realtime FPS.  I've programmed my own CNC controller to read gcode from scratch, 10 years ago, it was basic coding.  This is even simpler.

TOTALLY NEEDED AND A GREAT TOOL TO HAVE WHEN PROGRAMMING FOR 5 OR MORE MACHINES A DAY WITH MULTIPLE PROJECTS ON EACH. I'LL TAKE ANY ADVANTAGE I CAN GET WHEN DEALING WITH ANGRY MACHINISTS WANTING YOUR 1ST POST TO BE PERFECT... #MYONLY2CENTS

I didn't say it was impossible. I just said it would be difficult. These
simulations have to be rendered. Depending on if your computer is running
on horsepower or hampster power, everyone's experience will be
vastly different.

MOVE THE SLIDER TO JUST UNDER THE PLAY BUTTON TIP ON SCREEN, I FOUND THAT TO BE KINDOF A SWEET SPOT WITH MY STOP WATCH... #SHOPFLOORSTUDYLOL...

I too would really like the ability to view the simulation in real time. Like others here, I have been doing manual machining for a long time and have a feel for what a machine can and cannot do. While there is an obvious science to just knowing the numbers and I very much do want to just get to the point where I am looking at speeds and feeds only, it would also be very handy to see how the machine is going to move in real time for the time being. This way I can start to correlate what I am used to seeing/feeling with speeds and feeds. This doesn't have to be an exact real time (ie. what plays out on my screen is within milliseconds of real time). It just needs to be close. If an operation takes 1 minute to complete and the real time simulation is 58.5 seconds, good enough. Please make this happen.

Autodesk, can you please add a way to set the playback to real time speed? I don't get why this isn't in the software. Would be a really nice feature to have...

I came here with the intention of configuring the simulation to align with real-time operations. After perusing the comments, I am convinced that this implementation shouldn't pose a significant challenge. Given our collective experience and proficiency in utilizing Fusion 360's more advanced functionalities, it appears it should be in well within Fusion 360 team's capabilities.

I've resolved to contribute towards advocating for the inclusion of this feature within Fusion 360. As an integral part of an educational institution, I employ Fusion 360 to introduce CAD Modeling and CNC Manufacturing concepts to our students. I've chosen Fusion 360 due to its commendable equilibrium between user-friendliness and its seamless transition from CAD to Manufacturing, coupled with its state-of-the-art capabilities in line with current industry standards.

While I utilize this as an introductory tool for students to familiarize themselves with CAD and CNC, real-time simulation would prove immensely beneficial. This is particularly pertinent as they are still in the process of grasping concepts like cut speed and material properties, relying largely on real-time instincts rather than having fully acclimated to predefined cut speeds.

The students delving into Fusion 360 today will constitute the future user base and potential clients. With this in mind, I implore the Fusion 360 Marketing Department to advocate for the Developer Team's prioritization of this feature. Presenting it in this manner stems from the possibility that the Developer Team may be allocating their focus elsewhere. They might question the value addition this functionality brings, given that current users having success in project completion without it. However, the true worth of this feature lies in its potential to attract and engage burgeoning minds within the Fusion 360 ecosystem, thereby augmenting the likelihood of their becoming dedicated end users in the future.

+1 for this.  I don't need it to be perfect, just an approximation with a warning saying it is not exactly correct!

It doesn't need to be reliant on the user's computer's performance; it just has to bake the simulation. That is to say, it needs to calculate and cache the simulation before displaying it in real time, much like an animated film.

No, that would be extremely CPU/GPU/SSD intensive to generate and record an
entire animation like that. The simplest and easiest thing to do is simply
run a playback tied to frame rate, just like Blender and other animation
software does. Its very easy, and Fusion needs to step-up and get it done
already.

The fact that it's capable of generating the simulation faster than real time and caches the result unless "Regenerate on rewind" is selected invalidates this. Baked simulations require significantly less computation than simulating in real time; they just need to generate it first. The only difference is the steps are cached and played back.

I think you are getting baking the toolpath simulation confused with baking
the stock simulation. When you FIRST play the simulation, it shows all the
stock cutting away. When you rewind without regeneration, the stock is
already cut away and the simulation is therefore useless (to me, anyway). I
never ever rewind without resetting the stock back to uncut.

Either way, it doesn't matter, they just need to do it. They need to get
off their lazy seats and give us realtime simulation. The insane price
hikes are bad enough already, without even having a realtime playback
button to prevent crashing expensive tooling due to Fusion's toolpath
mistakes.

I'm not conflating them; they are two different concepts, but they are strongly intertwined. By baking the stock simulation, they have demonstrated the capability to cache simulation results. All they have to do is cache this result after each movement, which is more computationally intensive and takes longer than simulating in real time, but some scenarios that can't be simulated in real time on typical hardware would greatly benefit from this. I'm not arguing that Autodesk shouldn't implement either strategy, but I would like to see a combination of the two for these edge cases.

That is getting ridiculous. Autodesk team this is not serious of you. This thread is 8 years old, soon to be a decade without real speed playback. Fusion knows everything it needs, as it is able to tell the total machining time. Will autodesk someday care for the customer ? My bet is you'll never deliver because you do not want fusion to eat at inventor's market share.

I just checked my Mach 3 Mill software. It appears to me that it can display what everyone is asking for.
SO WHY IS THE MIGHTY AUTODESK STONE WALLING ?
