Titan. I’m a retired mold maker Used to run a manual horizontal boring mill. And toy guys smash steel and titanium like we used to hit aluminum. Mad respect! You speeds and feeds. ARE NUTS !!! You make me wanna get back in the game brother. Big love and respect

[@MrUnited85]

Man another awesome video done by the boys across the pond in good ol USA, so gutted I don't live over there otherwise I'd be applying to work for titan, such an amazing guy who I believe is changing the face of cnc engineering, BOOM brother!!!!

[@lumpygasinavacuum8449]

Titan just wanted to let you know I massively improved my career probably largely with the help of your videos. I am now in a mold building company. This is a dream job. Thank you. I still practice CAD CAM 20 hours a week or more. I would like to know how to import tools that are not on the tool list into Fusion from manufactors or anyway to import tools. Thank you again. God bless.

Titan, this. Just this does it for me, giving us a better and more complete explanation about this tech and coming through with some info. Around 0:50 🔥

[@pbrenneman5]

Thats a ridiculously heavy cut, could not even fathom that sort of radial & axial engagement in 4140 on a HAAS let alone at .014 ipt. Very impressive rigidity and power from that setup

[@DanielSmith-uy3yg]

lol, I have done that on Haas before no problem...

[@danl.4743]

0.014 is a lot?

[@robertsomerville5377]

@@metalman6708 Does your Haas have a 2 speed gearbox & 50 tapper spindle? Just wondering as I would like to buy one for my workshop.

[@robertsomerville5377]

I regularly run a 40mm bull-nosed cutter at 2400 rpm .015 ipm , 3600 mm/min It can ramp in at full width of cut. Axial is 3.3mm or .130". At the limit of HP , so can't go deeper. But tool life is good.

[@pakman422]

Haas wuld have no issues. I work in a medical shop running Ti and Stainless all day. And i run alot of haas machines. Vf2s Dt1s UMCs. Also a couple Grobs, DMGs and two Yasdas. Big boys. I promise you the Haas's have no issues keeping up. I take no less DOC or.WOC or IPT on the Haas EXCEPT some of the roughing that may be done on the Dt1s. Vf2? No issue. Especially if its the a Gear Driven spindle. The other machines are great at the tight tight tolerances and the micro-machining 5 axis toolpaths. Haas machines dont handle trying to hold tight tolerances using a .015 Ball mill with a toolpath that may not be much bigger than the tool.

[@sn0w_gel597]

Can you make a video about a real part being made like from order to shipping

[@spivzit8754]

Or like even a small batch of the parts would be cool. Material receiving, order example and a continuation of quoting, material prep, Programming, router generation, kitting, setup, run FP, inspection, run job, move job on for final processing, and from then on. Would love to see it all flow in your shop man

Probably not he makes areospace parts they are secretive.

[@Thewaldo12345]

He did a while back with one of the building blocks

[@ericspda]

Getting the orders is much more difficult than making the part. Making the part at a lower cost than anyone else tends to be the important part. And that’s not so easy to teach since it tends to depend on the exact part.

[@vaibhavsaraswat6966]

@@ericspda Well said

[@callmekimberly99]

In case you use Heidenhain iTNC you should use Cycle 32 to set your tolerance so it runs smother and its a roughing tool so the tolerance isnt that critical

[@rifl0rz]

Very important! Also if you do 5x milling you should also define the TA value in the cycle 32 wich is the tolerance for the rotational axes. If you dont you will probably get shitty surfaces.

[@matthewgowan7546]

For roughing, I'd like to see this set to 0.1mm tolerance, hsc mode 1. I'd also put a cycl def 32 with no entry, cancelling it before the next tool call. I'd love to see more about the new Celos control.

Hi Titan, love the videos and what you are doing for the industry! Would be good to see a video on how to read the different wear patterns on carbide tooling and how to adjust accordingly to optimise tool life/performance

[@TITANSofCNC]

Thanks and will do

[@alexkern9134]

Agreed!

[@vlatkopetrucci]

Hey Titan, I am very grateful to your efforts and educational principles, enthusiasm and knowledge about everything you shared so far. Many times you talked about kissing the part (meaning finish operations on a CNC machines where all the MRR are not so important, but the precision is... everybody understands that without the precision where its needed and good tolerances, the parts are scrap. You talked about big and powerful, expensive machines that not so many people around the world can afford, and don't get me wrong, that's grate but what about not so expensive machines, like routers, home builds -DIYs or professional entry level like Tormach or Syil when finishing op is done. What's the precision there. On a router where X and Y axis has different deflections (not equal deflection) because of the reaction forces milling steel or some tough materials. While boring a hole with Kennametal HARVI1TE, I noticed different precision error for finishing op, and doing ellipses when trying to make circles. What you do in that kind of situations, do you helix (wearing only the tip of the endmill)? or you go deep full depths but smallest radial increment (wearing because of increased friction because of the deflection , or you standardized the final passes with some prototype build and then go for large but precise series of parts. How do you charge for prototyping parts (because of setup type, coding and fixtures), corresponding to a large series. Maybe you will add something in next videos about it Thank you in advance for everything YOU ALL do here :) RESPECT! BOOOOOM!!!

[@RebbergbahnerEisenbahn]

We got last week also an new DMU-50 in our Shop😍😍

[@sarmik13]

Would love to have one, i am jealous.

[@bobm3781]

Hey Titan, did you know about cycle832 ? It will eliminate those jerky movements. You can add it using the high speed machining icon on the touchscreen, just select the variables you want to use. I program 3 dmu50's at work and could not live without cycle832. Just don`t forget to cancel before next tool change with cycle832().

[@TITANSofCNC]

Yes... Thanks

[@TheGreatBooger]

Mmm chips flying is so satisfying.

[@TriangleBox]

Your intro is AWESOME like WWE star

[@marosporubsky7033]

Hi Titan, great work! Definitely would love to see more videos about CNC Turning as well.

[@sshep7119]

I have a project that I may try to do on my machine, it would require some deep cavity surfacing. I haven't really come across any videos of that type of work. If it pleases the court, I would sure like to see a video that covers it. Extended tool stickout, extended tool holders, SF, RPM, cutter design, etc.

[@TITANSofCNC]

Ok, that’s good stuff... Definitely reduce RPM’s the longer your tool is to increase force and reduce vibration

[@patrickdupuis4871]

i am impressed i would be curious to see how this compares to dynamic milling

[@greg2337]

Dynamic milling with an end mill would be quite a bit faster. The advantage of this method is deeper reach with high rigidity.

[@martysmith2422]

Its moving kinda jerky between cuts. Is that normal?

[@BrandonKuiphof]

Could we get a video on hard milling? Probably don’t see it much in the Aerospace space, but we see it all the time in our job shop... and struggle every time. Specifically the job we are working on is for a hot stamping die. All the form steels are made out of Dievar, and heat treated to a 54-56 HRC. We were instructed by our customer to leave 4mm stock on all form surfaces and joint edges between the blocks, because of how much this steel warps during the heat treating process. We are struggling. Any help or and instructional video would be awesome on this! Thanks.

[@Reely98]

get the right tools, speeds and feeds

[@BrandonKuiphof]

Brandon Bartkowiak Brandon, we definitely aren’t afraid to get the correct tooling in. We bought 3 different brands of 2” inserted cutters specifically for this job (Ceratizit Button, Seco Button, Hitachi High Feed). Obviously we consulted with our tool reps to get the correct inserts in. To our suprise, the Hitchi is doing the best (550 RPM, 65 IPM, .012-.015 DOC). That being said, we aren’t cutting small blocks. Some of these blocks are 25” x 12” x 12” with the entire top form area having 4mm (almost .150!!) of stock on those form areas... that .012-.015 DOC, as you can imagine is taking forever to cut these blocks... I’m just looking for more advice from others out there that aren’t trying to sell me tools (like our tool reps). As you can imagine, an end-mill, and we specifically keep Helical stocked in our shop, will not cut it for roughing out these large, 3D form surfaces... All i really see from Titan is him cutting alot of the exotic steels, or aluminum. This is really one of the first videos I’ve seen him cutting a piece of steel that I specifically cut day in and day out in a heavy Tool and Die oriented job shop. I think it would be cool to see more videos cutting these steels, hardened tool steels, etc. because I know there are plenty of other shops out there like us in a heavy tool and die oriented space.

[@zundappchef]

@@BrandonKuiphof switch to high flute high angle solid carbide endmills and take fast but light cuts for hogging u can stick with 2 inch or 2.5 inch cutters with round inserts i can send u some tools i use to cut that hardness the only thing u need is a riggit setup

[@hamp777]

@@BrandonKuiphof In our shop we do 2mm of stock on that big block. But your speeds and feeds are kind'a ok. That's how it's done when it's hardened to 56Hrc. At least this is how we do it. We use YG-1“BLUE” Coated Nano Grain Solid Carbide End Mills.

[@Adam-b8i]

Seems like a good tool for shoulder work. But I’d wager a 2” high feed 6 would get this step of the work done faster. Maybe that would be a good video. Same part with a couple of different strategies and a breakdown of tool and time cost. Love the DMU😍

[@b2manufacturing]

Hey, can you show how you make custom soft jaws for complex parts. With multiple depths and angles. To be used For flipping a part over to mill side-b? If you already have a video can someone share a link?

[@justinscott2500]

Hey Titan can you explain what parametric programming is and if you use it in your shop?

[@anthonyclancy308]

would there be a stress relief before finishing this part? that seems like an awful lot of material to remove and not expect the part to distort after removing from the vice....

[@dirkjanvanvliet]

Thanks!

[@justinl.3587]

Just curious why the machine seems to be making jerking/twitching movements in between some of the cuts. Does it have something to do with it being a linear machine?

[@callmekimberly99]

The Problem is the set tolerance if you dont set one at the machine controller the machine goes to every exact point

[@WasNiksIsNiksWordtNiks]

Justin L. It’s not a linear machine. The guy above me explained the yerking. It’s the way the control and CODE are programmed and which tolerances are used. I’m sure Titan is still in the testing phase and the Post and programming will improve in due time 👍🏻

[@Sicktrickintuner]

Yep still looks like a new machine inside it

[@justinl.3587]

Thanks everyone. Makes sense. I'm not used to the newer CNC's. I currently run a horizontal thats about 8 years old and it acts a lot differently than some of these newer marvels.

[@mrbumcraic5046]

Wouldn’t it be nice if a modern day nc machine was built with as much mass as a 1960’s English or German machine The vibration on that 1st cut shook the camera

[@mrbumcraic5046]

Remote Broadcast Shows the machine was shaking Cutting 4140 at those depths and feed speeds is still impressive

[@Clarsen1990]

Do they recommend running it without coolant or is it just for filming purposes?

[@WasNiksIsNiksWordtNiks]

Christoffer Larsen Insert tooling doesn’t like coolant when it comes out of the cut. Makes them brittle and breake sooner. That’s a very short explanation. There are lot’s of nuances just like a lot of area’s in machining

[@TITANSofCNC]

No coolant, just air blast on 4140 Steel

I think you need a longer mill. Probably could've roughed out that curvature in two or three passes then came in with the smaller cutter and begin rough profiling. Not sure of the power of the machine though.

[@dan3076]

prehard or annealed?

[@customtobi576]

Hi Titan. I‘m a cnc machinist and programmer from Germany and i really like your videos. But please tell me why the toolpath on this part sometimes is so „strange“. It cuts on one corner and left some material than goes around the part and cuts on another corner than back to the first corner (hope you know what i mean?) That programm could have been a bit more efficent. I see this back and forth on a lot of videos on youtube. But why is it done that way? Is it something that comes from the CAM-Programm? Or is it just for tool-demonstration? Or is it the best way for toolwear? Maybe i have to add that most of the time im working on lathes with livetools and subspindels with mostly easy mill or drill operations. So im not so used to this step-by-step line milling.

[@TITANSofCNC]

It’s called Adaptive Roughing

@@TITANSofCNC It just needs a cycl 32 in the code after the tool change, adjusting the tolerance in the cam toolpath won't have as significant effect as cycl 32. Try a 0.004" tolerance, with hsc mode 1. It needs cancelled before the next tool call, or the next tool will still have it applied, just another cycl32 with no entry.
