KOR-5 | KING of ROUGHING on a HAAS UMC-750SS | CNC Machining

[@The-Gingineer]

You're machining faster than my little mill can rapid...

[@CNCLearningAndEngineeringTech]

Perfect CAM programming. Awesome work.

[@ugetridofit]

Love you vids. I am not a CNC guy, so here you are making a part from a block of aluminum. I never seen a video for how you remove the part from the rest of the block that is clamped to the bed.

[@TITANSofCNC]

Go back a few weeks and you will see a video showing the making of that fixture plate and how it works. Thanks

[@phillipwebb9741]

Mr. Titan, you are a genius. I wished I could work with you. I just want to learn more.

[@stexxvan]

Nice to see there is still new videos coming up

[@randy80ism]

How good are those machines to machine on cast iron? Just asking because they have a small CNC machine at my work. It machines the parts very slow. Compared to an old agent hydraulic machine called a carousel that has 5 stationary stations.

[@frankr608]

Is your UMC fixture interchangeable to mount on your DMU 50?

[@TITANSofCNC]

Yes

[@Evolvescalate]

I dont work much with aluminium these days but when i did i remember we used to rough both sides climb & conventional, saves quite a lot of time on the rapid moves and the overall movements. Not sure it will work with this kind of feed and AP but if it would, it would save quite some time. Have you tried it ? Im curious :)

[@TITANSofCNC]

It works great in some applications, and not in others... your running over your chips in tight spaces... but with aluminum it doesn’t really matter. Tool gets dull faster... but if you save money then it’s ok

[@StraightUpFerret]

What is a good resource for determining optimal RPM? We usually run our tools at the highest RPM we can but running at max torque would be useful

[@TITANSofCNC]

Ask for your torque curve on your specific machine. There is a balance as higher RPMS reduce pressure especially with 5 flutes. So go 20-30% past for high end torque RPM... and try it.

[@StraightUpFerret]

Thanks for the help!

Groove lock shanks have a corresponding ER Collet ?

[@TITANSofCNC]

Safe-Lock sleeves I did a video on it a few weeks ago.

[@mustaphaaitkhouyaali430]

How.much step over are u doing ?

[@corsiar]

What CAM software was used to program these cuts?

[@Not-C-418]

When i get a CNC machine i will sleep inside of it for the rest of my life .

[@The-Gingineer]

I mean, if you sleep in it while it's running, you'll def spend the rest of your life in it...

[@Not-C-418]

@@The-Gingineer let me get one first i will deal with the noise problems later 😂😂

[@goldman7267]

He didn't mean noise problems, he meant you'd be ripped apart by the tool. You wouldn't need any coolant though

[@josha9620]

I have a question I run my Haas vf3 around 90 to 100 load when roughing now with a dynamic cut when the cutter enters the cut it can get up to 135 is this hard on the spindle running hard like that all the time?

[@TITANSofCNC]

Make sure you ramp in Radially... gradually... so the pressure builds to 90. Don’t dive in at 90’ instead come in at 30... but Fast. In 5 yrs you might have to trade out a $6000 Spindle... but with an aggressive style... you will have made enough money to buy 10 + spindles etc:-)

[@marcusmadrid7508]

Can you push more radially? Like 30%

[@ExMachinaEngineering]

@Travis Casey Actually the gullet has to do with chip thickness, not radial engagement. I would guess, sure you could do 30%, you could even do 100%, but you would have to reduce the feedrate to an extent that you get less MRR. I am guessing here, have not used the actual tool.

[@1Corinthians151-4]

5 flute aluminum cutter? That's very unusual... I always use 3... but the results are speaking for themselves

[@TiMechOfficial]

but thats aluminium or steel? can you test something like - we called this in germany - X 155 CrVMo 12-1 ? would be interesting what feed rate you can use for this material?

[@DiDe273]

Some blend of cro-moly vs 6061? C'mon man you know the results

[@TiMechOfficial]

@@DiDe273 na sorry im not into that i machine daily these types like X155 or X210 or 90MnCrV8 / X8. but as is said would like to see this mill with these materials how they work together!

[@timothycharley2584]

Only 8500 rpm? Is that because the HAAS spindle sounds really bad at 15,000 rpm? Destiny Tools still have more metal removal rate and cost 1/4 of what they're asking for Snor-5 😅

[@TheAlexLegolas]

Whats 10% ratio? Great advice

[@fordhoarder]

10% of the tool's diameter. In this case it's a .750" tool so his radial step over is .075"

[@TheAlexLegolas]

@@fordhoarder Thanks.

[@pawan0164]

How is the tool life?

[@TITANSofCNC]

It’s a Beast and runs forever... I have never broken one, even when it gulled at 1600 IPM. Crazy

[@pawan0164]

TITANS of CNC: Academy thanks for the information

[@RAVANASURA68]

Superb

[@ragupathimech8489]

Wow😮😮😮

[@Thepriest39]

If I could only get one of those machines...

[@returnedfrompanama]

The step over distance seems too small. You should be hogging more than that. You could have run that at maximum rpm.

[@mash8050]

Now try this with Hastelloy 😉

[@TITANSofCNC]

BOOM 😂😂😂😂 kzbin.info/www/bejne/j4OTaGeMmJtsq80

[@Motor-City-Mike]

If you're going to show"the king of roughing" show it in steel - even 7075 alum. cuts like butter, even with a conventional two flute high speed steel endmill. It's hard to even call that roughing, you're not going to push any cutter near it's limits in with that small diameter holder - it's going to chatter first, except possibly in 6061, which is about as tough as marshmallows. We also run high helix parabolic flute endmills - in Solid, large diameter holders.

[@TITANSofCNC]

There are a million materials and types of tools... I really break it down into 2 sections as standards are concerned. Harvi 3 which was chosen by Boeing over all competitors as the number 1 tool for Titanium... I use that for all steels, titanium, Inconel and Monel etc. But what about soft materials where you need a sharper edge? King of Roughing is actually the name as it’s what KOR stands for and 5 is the flute number. This tool drops 180 cubes with a 1/2 so it definitely out performs all competitors in aluminum etc.

[@Motor-City-Mike]

@@TITANSofCNC If you say so. We use a lot of half inch 2 and 3 flute streakers (plenty sharp edged), both pocketing and periphery cutting. (Mostly 6061) For pocketing I use a single ramp/plunge to roughing depth - usually 150 - 200% of diameter, use 85 - 90% stepover running 200-220ipm, the biggest issue is chip evacuation even with the high helix - I actually prefer the two flute in pockets for that reason. Periphery, 90% wide 150% deep and all the feed the setup will stand, I ramp over on the first pass to gradually build tool pressure The only limits we see are spindle speed - 8100 max. As an aside - I don't have a lot of respect for Boeing, they're probably much better now (way up there) but I'd seen some poor decisions/endorsements by/from them in the past.

[@Motor-City-Mike]

@@TITANSofCNC I'm curious, do you have access to spindle rpm, step over and depth of cut when they arrived at 180cu in? Was it a sustained cut or a short/quick pass and then calculated from there? At say 30,000 rpm and 5 flute geometry it doesn't take much chip load per flute to generate that number. I also wonder if it's sustainable, even with the knife edged, cup faced geometry and mirror like micro on the face of the flutes I'd imagine metal transfer to the cutter would limit the amount of time. They're seriously honest questions. "Burst passes" - I don't know the technical term - during high speed machining cycles generate some impressive numbers but the tool life at those numbers in a continuous cut situation intrigues me. I tend to be a bit pessimistic about advertising claims. Just to qualify myself as to the basis behind my questions, I have 40 plus years in the trade, a 2yr. "pedigree" in manufacturing engineering, have been programming 3d/multi-axis since A.P.T. was the industry standard, instruct at the local college, and constantly stay on top of advances in the machinery/tooling/software in our world. The most "significant" machinery I've been responsible for is an 11 axis Nakamura - it was interesting work. If there's something truly significant here in tooling I'd like some verification if you are privy.

Lol. Feed outside the material is lower than in xD
