The correct way of writing metric cutting conditions is: Spindle speed: RPM Surface speed: m/min Feed: mm/rev AP/DOC: mm

[@balooc2]

just a tip: when you show the metric values you're using, use the metric standard for tools aswell. for example: you would call a CNMG 12 04 08 a CNMG 432, or else most people would have no clue on what insert you're using!

👍 good job titans of cnc

[@f.x.gernstl1842]

Nice job. How long did it take from the start of programming and set-up to the finished part?

[@brandon184839]

They should include run time in their videos

If you’re not already. You wanna be using a do/while loop on your hex flats. Saves a lot of messing about if you need to modify for different sizes 👍🏻

Does he have any tutorials of his mastery showing how he programs all these operations?

[@user-rh6mk5vy3z]

nice one :)

[@jasonbeatty4108]

You should try the new KCS10B grade in the titanium.

[@littlephilo585]

Never worked with titanium, it sure sounds hard as hard!!!!!Great job Tyson!!

[@rickmcgowan5993]

Titanium is not hard to machine, nothing special about it other than knowing the correct tooling to use and the speeds and feeds to use for your specific operation. It's just part of the myths that are in the industry to keep others from machining those types of materials. Titans of machining is nothing more than an advertising ploy for those who have no idea what is going on and taking advantage of people (aka marketing scheme). Don't be suckered by the B.S. and challenge yourself to find a place that does the type of machining you have interest in doing or you find challenging.

[@ryankrolak7147]

That’s a pretty cool lathe Chuck, what is it called? Why 6jaws?

[@marc-antoinethebeautiful7714]

After seeing this I would recommend to skip the milling of the ball nose etc for a milling machine you have a nice hexagonal to clamp on a 4 axis closer to where you would mill :P , I would use the face mill with both turret grabbing for more stability to go faster, add an boring bar on the lower turret to do has much has you can on the second side and put all the turning OD on the lower turret. This way you could maximize when you are ready to do simultaneous turning and milling.

[@brandons9138]

This program is a disaster from a production/machine utilization stand point. I hope this was done purely for demonstration purposes. My boss would kill me if he came by and saw that only one spindle on the machine was running at a time. Especially on a machine that is easily a $200/hour machine.

[@johna2076]

@@brandons9138 Interesting Brandon. Can you please elaborate a little more on what ops could be done simultaneously on this example part?

[@brandons9138]

@@johna2076 The main spindle work in the first video is mostly milling, yet they tie up the milling head doing turning work on the sub side for the majority of the work. If you took the turning tools off of the milling spindle and put them on the turret then the milling head would be freed up to work on another part in the main spindle. There may be considerations for tool overhang or availability that may not be obvious in the video, but I didn't see anything that looked like it was a large tool projection that couldn't be handled on the lower turret. The main spindle sits doing nothing for the entire time the subs spindle is running. This doesn't condense the cycle time since op1 isn't being done at the same time op 2 is being done. Basically this method is no better then doing two separate ops on two machines.

[@johna2076]

@@brandons9138 Pardon my possibly dumb questions - I have a 3 axis mill so this is different for me. If this was a production part then wouldn't part 2 be worked on in the milling spindle while part 1 op 2 (2nd vid) is being worked on in the sub spindle? ie once you have multiple parts in progress then both spindles are both working?

[@brandons9138]

@@johna2076That would be the plan ideally. The way it's currently programmed and setup the milling head is busy doing turning work on the subspindle side(op2). Meaning that the milling head can't do op1 work on the main spindle, as it's tied up working on the subspindle.

[@vonpredator]

Question on the final Thread operation. I would assume the tread is checked before the part is taken out of the chuck. If it was found that the thread is out of spec. What would your corrective actions be?

[@HoChunk85]

At our shop, yes we check the thread before removing the part and if out of spec I.e over sized we can offset the tool and rerun. If undersized then unfortunately a scrap part and the offset would be for the next part.

[@tomaszspiszak181]

There's a way to recut thread if oversized, and part was out of the lathe.

[@brandons9138]

In a shop that is running production for aerospace/medical they have to follow strict inspection guidelines for in process parts. After so many parts, like 1 out of 5 or what ever AQL level the customer needs, a check is done aa well as documentation of the dimensions for that part. With that type of system you should be able to see any tolerance creep on a feature and make adjustments accordingly. Of course a good machinist will look before removing the part to see if there is any obvious discrepancies in the finished part. If the threading insert took a crap on the last part you'll be able to see that in the resulting burrs or bad surface finish. At that point replacing the insert and fixing that part would be prudent, but checking each part while in the machine is production killer. With a low volume of parts you can get away with checking in the machine, but if the volume is high it just murders the machines through put. If they were serious about production volume they would have loaded another blank in the main spindle and programmed it in such a way as to full make use of the milling head and turret at the same time. Doing this part like this is no better than doing it in two separate machines, especially seeing as there are no features created on the sub spindle side the need to be key/clocked to features created on the main spindle side. The real benefit from a machine like this condensing the cycle time down by doing as much as can be done on each spindle during each cycle.

[@vonpredator]

@@brandons9138 Thank you for your detailed comment. Very insightful! These automated threading operations on CNC lathes is one of those marvels of engineering that if you sit down and think of everything that has to align up at just the right time it will make your head hurt. Seeing, for example This Old Tony do it manually, CNC looks like magic.... Stay safe!

[@vonpredator]

@@tomaszspiszak181 Would be interested in hearing about that? I hope you are not just referring to using a die to tap it? 😉. That would be cheating. 😜

[@agostinocavazza9731]

great job congratulations, and very stiff machine!

[@jaymgil]

Why did you buy all of these machines if your moving to Texas?

[@caseyman97]

Chicken and the egg, I'm guessing. I've never been through the process of ordering a machine (let a lone of this caliber) but I imagine it takes awhile to go from inquiry to an on your floor.

[@jameswattenbarger2498]

It’s roughly a 6 month lead time to get a 9 axis from Mori, they build them to order.

[@TITANSofCNC]

Truthfully, everything was already set in motion... then one day I woke up with Texas in my head.

[@davidvoitle2502]

Welcome to Texas. You will love it here. I have been in the machining industry for a little over 30 years here in Texas, quality for 24 of the 30. The work you do is awesome!!!

[@ramazancolak3105]

You should have started with the drill in the second opp...

[@gabebolton4604]

So when drilling, you spun the tool, but when boring, you spun the part. Any specific reason?

[@darikmatters8866]

I was wondering the same thing.. I would guess that they are saving the bearings on the main drive as the boring bar is not balanced but its just a guess.. Would like to know the real answer as well..

[@jameswattenbarger2498]

@Ultra CNC , they should’ve locked the drill in place and spun the part. I’ve ran a 9 axis mill/turn the past 5 years. And we have done it both ways and I can tell you that spinning the part is way better than the drill. It’s so much smoother.

[@inuyashacoolieo]

If I had to guess it's because you don't have to worry if the drill is exactly on center since it is rotating about it's own axis. One nice thing about rotating the part instead though is you can cut oversize to a certain degree (at least with Sandvik 880 drills they give you a range) and you can even use the drill as a boring bar (if your insert drill permits) to open the hole up more.

[@jameswattenbarger2498]

@@inuyashacoolieo , we run 880 drills and they run amazing but we spin the part. But they are coming in with a boring bar afterwards so the drill being off center really doesn’t matter. It would be easier in the machine if they spin the part and not the drill.

[@inuyashacoolieo]

@@jameswattenbarger2498 yeah, I realize they are boring after. I meant that it didn't matter for the drills sake if it was off center a little. Whereas if the part was spinning and the drill stationary and the drill wasn't exactly on center (or below center 😬), the drill could get scrapped. With the drill rotating there's no way that could happen since it's spinning perfectly about it's own axis.
