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.
@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.
Ich bin Einrichter an CNC-Drehmaschinen und arbeite oft mit langen und dünnen Bauteilen. Dieser Tipp ist wirklich Gold-Wert. Ein paar unsere älteren Maschinen Doppelspindel-Anlagen können SSV nicht, aber Dank dieses Videos konnte ich diese Funktion "nachbauen" auf FANUC 18i-TB NUR mittels Makroprogrammierung. Funkioniert sogar sehr gut.
Again, HAAS destroying the competition with great info for those new to machining and veterans alike. Good luck in March at the Australian GP race. I think you guys did a solid job on getting your F1 program together, now its time to take some points...
+TacticalKeychains my comment said "info". Not the anti chatter system. As for sales BS...how about all the others who don't list thier $. That is so the dealer can play a game with you. Make you feel as if you got a deal. I'll take showmanship over bending over anytime.
+Wild Iron im going to school for precision machining doing cnc lathe rn actually and we havent been taught svc i can only imagine us using sfm atm with the parts we are making
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.
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.
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.
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
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.
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.
Keep up good work.. I never stop learning.. Fresh out school northern CA.. I cnc haas lathe plastic all day. Delrin, vesbo, pekingese, pek glass field, havlar. Keep up the good work.. Btw I'm 35 and grew up playing paintball.. Currently own tippman a5, gt rid my Bob long and angle electronics
+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
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.
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.
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?
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.
5:51 yes yes but it can make it worst too. macgine has spindle speed knob tour it 90%-110% in second. manual ssv. cut deeper les shatter. buy bette machine no shatter
disgruntled181 I'm here after watching his video also. Though I didn't follow any link from the comments. Apparently since I watched his video, UA-cam decided to recommend this to me.
Nevir202 Think I saw it my recommended as well but one of the commenters was pointing out to AvE that Haas did it first, though watching their vidjeo it was not the same method.
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?
+Mike Mai We're glad you found the video helpful and thanks for the compliment. SSV is available on all Haas lathes from the TL-1 all the way to the ST-55.

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.
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!
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 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?
9:28 like cutting speed manufacturer give awesome ranges. its same as rapidly change speed override 90-110% every half second. same result. or let rasberry pi do it for you.it can control fanuc LOL
In Fanuc you can develop it by your self quite easy by using "real-time macro" so your old "fanuc lathe" with this option can do this. Siemens has this feature avalible to donwload and integrate on (almost) any Siemens controller. Both controllers will also adjust feed to the actual spindle speed.
Zentrifugaler druck durch rotation< schneidendruck des werkzeugs=keine rattermacken am teil, man braucht kein SSV WENN MAN ERFAHRUNG UND INTERESSE AM BERUF HAT! Ausserdem vermindert man solche Umstände indem man nur bruchteile der gesamtlänge schruppt während der großteil der Welle noch einen massiven durchmesser und somit genug Stabilität besitzt, das was ihr da zeigt ist nicht effizient, ausserdem schlechte werbung wenn man zeigt das es bei WIRKLICH filigranen konturen nichts bringt xD
11:32 Now you know. still parameter 165 change RPM not % LOL 166 still going same time cycle. should they change? LOL yes thats why its use this RANGES lol
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?
I'm working on a DMG delta and an emco. I work propeller shafts for ship propulsion, which are 2-4 meters long. Material goes from 42crMo4 to high alloyed steels eg. X8CrNi18-10. never had such problems. Haas are just bad and you will hardly find in German companies.

This was a very clear presentation. Thank you very much.
Hey it’s like how my grandpa use too drive on the freeway; it all finally makes sense.
Very useful feature, also pretty easy to implement in Fanuc 18T and similar using Macro-B with SAR bit disabled.

Brilliant and obvious. Great application. Subscribed. Fantastic concept. Thank you.
Once again, Great Job Guys!
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.
As a hobby model engineer, I have learned something new today. As a professional electronics engineers, it makes sense to me.

Blimey!!! You need a Doctorates to be a machinist nowadays
Chatter: The sound of dolphins being killed by lasers.
Great video, the animation Fantastic! chatter is there if your tooling is bad or your machine is out of alignment/ weak my 2cents.
haas at its best ..superlike
A good idea. Is this option available for milling?
Great info
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 ?
use tougher material spring steel for example beacause it stores more mechanical energy and will shatter much easier
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.
it should be very helpfull for me. sometimes i have very thin shafts i need to turn
If u have fanuc i have a solution for u
@@Reficul999 i am also a fanuc user. please kindly tell me the solution for using ssv in fanuc
good job guys :-)

Anybody else notice the tool height wasn't centered with the center of the material in the chatter animation?

+Haas Automation, Inc. So with SSV on the SFM of the tool is fluctuating.
Max Maruszewski The SFM is only a function of the workpiece diameter and rotational speed, so yes, it changes.

+Jay McCrary We don't recommend using SSV during threading, since it can negatively affect the precision of the thread pitch.
hmm interesting, i normaly just dropped the rotation
Great explanation!

its even more effective when boring, like a 12in long 1.25 bar full depth on a tl 1. it makes a big diff.

does that not reduce the tool life duration? maybe the silence tool from sandvik would be less expensive over a long time..

Good question Ferhat,
When SSV is enabled the feed rate remains constant while the spindle speed varies above and below the commanded spindle speed.
It's a very helpful video. What model of Haas Lathes are come with SSV feature?

Not all Haas lathe has this new feature, we have an old SL-20 on the the floor that has highest setting is 160, not even 165 or 166.
Could just rap something around it like a silencer...

Whether there is it in Russian?
does this also help to stop chatter on long boring bars?

please sir upload more videos
I feel like this is really torturing the motor and the VFD.
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?
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
9:28 like cutting speed manufacturer give awesome ranges.
its same as rapidly change speed override 90-110% every half second. same result.
or let rasberry pi do it for you.it can control fanuc LOL
Just increase or decrease the speed and avoid the resonance all together...
try it on 5.85mm inconel 718 at 136.5mm long..... if you can cure it do let me know :)
This was very informative! But I have a question:
Does the SSV function only apply to Haas-machines or is it built in to the overall Fanuc system?
There may be other machine tool builders that have similar features, but this video refers only to Haas lathes. Thanks for the question.
In Fanuc you can develop it by your self quite easy by using "real-time macro" so your old "fanuc lathe" with this option can do this.
Siemens has this feature avalible to donwload and integrate on (almost) any Siemens controller.
Both controllers will also adjust feed to the actual spindle speed.
MANDELAZZA looks like an application for parametric programming if your machine doesn't have it
Any CNC lathe with a spindle encoder that I've ever used can do this...
Where in the program do i put the m38 code?
My boss wouldn't be happy if I would waste so much material for testing these features.
It wouldn't waste anything if you test it in what would normally be the rough cut, chips are chips!
Would it be same thing when dealing with threads .
