@Yeah Right "Tool Pressure" may I have an explanation? I've had lots of problems with chatter and it's almost always boring bar length or not enough support on jaws. Actually is there something I could read up on that you would recommend on this topic because I was just thrown in on a cnc lathe (not a HAAS) and had to learn everything on the job.
My machine doesn't have SSV, but I use this technique manually with the overrides and got great results. When you do not want or can't change the setup, rapidly changing the spindle speed works. Especially when you're facing and getting chatter.

This is outside turning example, we tried at face turning and worked fine after several variations. It’s interesting that Haas service people we asked have no information about that and said impossible. We tried SSV for chip breaking while parting operation, it can be better with fine adjustments. Thanks for good and standard feature.
Most innovative and beneficial thing to come to CNC in a long time. This would work on practically anything with moving parts- could be hugely beneficial for small hobbyist CNC systems.
All I have to say is this just made my day. I have a 7 inch long 4 in diameter round bar that is screaming at me.. watched this video during lunch and today's aggravation went away just like that!! Thanks
3:40 There is conflicting information in this video. The narrator says SSV increases spindle speed by 150 rpm, then decreases by 150 rpm. So it should be back to 1500, but instead it shows 1350.

Sir, I am working on Portal wheel lathe used for turning of Railway wheels (Make Safop) and facing issue in matching wheel profile at higher depth of cut. After profile matching with tool offset, when we make a radial cut upto 2mm we not find any issue. But when we increase the depth of cut we didn't get the required profile. May be it is related to cutting speed, spindle speed or any other factor. Requesting you to please help me in this matter.
One thing they didn't quite explain: Around 2:50 they show the spindle speed varying above and below the resonance speed, but don't explain why you wouldn't just pick a fixed spindle speed outside resonance. I can some of with three reasons: 1 - The system is probably a nonlinear one, and so it will resonate at a wide range of frequencies; varying the driving frequency prevents the resonance from growing to a significant amplitude. 2 - The resonant frequency will vary as the part is machined and so will eventually match any particular fixed spindle speed 3 - Determining a safe spindle speed is pretty much by trial and error, resulting in many scrapped parts during test cuts
Here in Peru Haas machines are known for having the parkinson effect, they shake even under normal cutting conditions. Chevalier machine don't have that issue. Loaded with Fanuc or Siemens controls, very rigid spindle head plus a proper machine weight and geometry we have not experienced these kind of problems. This SSV will work for Haas, other machines don't need it.
Hi, I'm not sure if anyone (at Haas) monitors these comments but if so, I'd like to say thanks. This gave me an idea to try it on my machine. On an 840d, you can use synchronous actions to read the actual spindle and vary it by a % and time. This means it works in g96 and g97. Additionally, you can compare the actual to limit and if they are equal, the variation slides down instead of sliding up and down (moves the setpoint). In this way, there are virtually no limitations. Would this be possible to develop for your controls?
+Joey Murphy Good eye Joey! It was just a simple graphics mistake, but running a tool that far off-center could actually cause the chatter that SSV fixes. Can’t decide if that’s ironic, or just unfortunate. Thanks for making us aware. -Mark, Haas Tips of the Day
I think a very important point was not covered or maybe it should be assumed? Does the federate try to follow the spindle speed to maintain a constant surface footage? Would SSV be generally more or less effective if it did or did not?
+Max Maruszewski This is the beauty of SSV. It maintains the same Feed Per Revolution, while the spindle RPM varies up and down to keep the chatter away. Your parts will get the same consistent turning finish, as the feed does follow the spindle RPM with SSV.
I tried it at work today using SSV but it was not working. Is there a specific cycle it can only run in? Such as a can cycle? I am running a linear G1 to make Edge breaks , turn down the diameter and another Edge break before that same tool parts off the parts.
What about increasing the depth of cut and reducing the feed. Load up the tool a bit more. Is SSV the same as harmonic balance control? I must congratulate HAAS on these excellent videos.
Hey, I was just curious, can SSV be applied and disabled inside of a canned cycle such as G71? I have made parts that have a large stable diameter closer to the check but further out have chatter issues due to the small diameter... Just wondering if on the first/second line of an G71 if it can be turned on then turned of once its moved along the part into a larger area. Tks!
Does the feed speed automatically (dynamically) match the variable spindle speed, or is it just a variation of the spindle speed regardless of the feed speed?
Can you please give us a example of the M38 use in the gcode? Does it go before or after the G96? Can it be used with G97? Where does the M39 (cancel M38) go? If you put in another G96 or G97 line is the M38 still active? Thanks for your help.
If you use a face grooving insert turn up the 7in or so with little to no chatter ive finish turned 16in 1.5 dowell pins between spindes no chatter .0015 tapper.
if chatter is caused by the spindle spinning at the resonate frequency, and ssv just make the spindle spend less time in that frequency, then wouldn't increasing rpm the rpm out of that frequency and leaving it there solve the problem?
I work on a TL2 with the older screen set up. I can insert the G38 code into my program to start SSV, but how do I program the speed variation and timing?

This was a very clear presentation. Thank you very much.

Maybe this sounds a bit off technical, but can't you change rotation of speed so that the frequencies don't collide. Is SSV really needed then ?
Hey it’s like how my grandpa use too drive on the freeway; it all finally makes sense.
I've programmed that style with fanuc before, it really works!
A good idea. Is this option available for milling?

Max Maruszewski The SFM is only a function of the workpiece diameter and rotational speed, so yes, it changes.
Love the mimics of that guy in the video xD .
Very impressive. It would be just as helpful on the milling machine to. Is also available on the VF2?
Much more helpful is to use SolidCAM, which will tell you if it will vibrate or not already before cutting anything.
Great video, the animation Fantastic! chatter is there if your tooling is bad or your machine is out of alignment/ weak my 2cents.
This would save my index fingers a bit of work :P i routinely employ this technique but having the machine do it for me would be handy haha.
Brilliant and obvious. Great application. Subscribed. Fantastic concept. Thank you.
Once again, Great Job Guys!
As a hobby model engineer, I have learned something new today. As a professional electronics engineers, it makes sense to me.

Nix Ryu no because it will start harmonizing and it will start to vibrate again. Varying the spindle speed will keep it from vibrating alltogether.
Harmonics, the part can still vibrate at other frequencys

Hello Salim,
G50 can perform several functions. It can set the Global Coordinate, it can shift the Global Coordinate, and it can limit spindle speed to a maximum value.
G92 is used most frequently for simple threading. It can also be used for multi-pass and tapered threading.
Spindle load % and spindle motor temperature will increase proportionately. . Need to be careful.
