IMPOSSIBLE MACHINING TEST: Inconel 718, Kennametal Ceramic End Mills & 1.5 HP TORMACH

[@nickvasquez85]

At my last employer everyday we slotted, pocketed, and drilled waspaloy, hast X, inco 625,718, 713 (casted version of 718) on a 2005 Haas Toolroom mill TM1. It can be done just have to match the cutting parameters to the machines rigidity. love your guy's content. keep it coming!

[@scottknight1301]

I think this is why so many people are getting out of machining is because the company owners don't realize how smart you have to be to be a great programmer/machinist. They think it's just here's a file and boom there's a part. I think it's funny how most places put so much into their engineering but so little into the guys actually make the parts. I've had to search so long before finally finding a place where this is appreciated. Definitely an underpaid, under appreciated profession these days. At least in my experience.

[@angrydragonslayer]

Man, i'm still mad about a place i used to work at They refused to let the part designers actually learn how the parts are machined and so we got completely absurd geometry to work after (like a few dozen holes at very specific different angles) that just werent feasible with what the company expected us to do it with (entry price second-hand VF1s and a single VF4, none with automatic probe and only the VF4 with a >$150 3D taster)

[@SuperstarComponentsLTD]

Would help if you weren’t shanking out on the ceramic. I bet it would work high feed style. Turn it up till it goes bang then 10% slower😁

[@davidfarmer]

I think it may have pulled the endmill down. not enough clamp force.

I am a fan of TITAN LeRoy, the academy, his new channel Makerspace77, and what he stands for. An inspiration to manufacturers. I've watched hours of videos and learned a lot, but 1:35 into this video might be my favorite moment so far. LeRoy "going crazy" from isolation but visibly having fun playing with his awesome 'toys'. It didn't work, but that how we learn. As always thanks for sharing.

Thanks Michael... I really appreciate that comment. Got to have fun right😁 PS. First name is Titan, last is Gilroy. Take care and be safe.

[@stbentoak5047]

Ran Inco alloys for 20+ year for GE aircraft engines hot zones. 2 things that will increase your tool life dramatically is a Chipblaster for High Pressure coolant on both Mills and Lathes, and run your Blaser at 2x the recommended concentration for tool life. Also I know you are a Kennametal guy... But Sandvik and Quick change Capto holders whip the snot out of Kennamatal stuff in tough materials....

[@DistantVision85]

I just built a diy cnc router, and I was running a 6mm 3flt endmill through MDF at max speed(30k rpm), and my machine was doing small pockets for t-nuts. Everyone says max rpm is the way to go for wood, but it almost started a fire after only about 8 pockets. I was watching the whole time, but I realized I need to get single flute end mills to be able to get my speeds and feeds anywhere close to where they should be. For some reason my machine is very slow when doing tight little holes. I think I may be working at too high of a resolution. A single flute at 10k rpm would need about 200i/m, and my machine, for whatever reason, slows down to anywhere between 4-24i/m for small details. I am still new to the DIY side of this, and at the moment I use GRBL on a arduino uno, running off universal gcode sender v2.0.. Seems glitchy, but better than easil. Havn't tried chilipeppr, so it may be a better option. Who knows what else there is, as there seems to be all sorts of different programs for different stuff. My 3d printer runs on repetier host, and almost wondered if I could repurpose the board off one of my printers that is broken. 🤔

[@kevinc9006]

Happens everyday

[@advil000]

I know the 770M has a little more guts than my 770 S3, but I'd try a smaller version of the end mill. If you need to really haul to make the insert work the spec sheet calls for up to 10% tool diameter. Taking a .010" DOC with a 3/8 end mill has some SERIOUS chip thinning problems. So a 3/16 or 1/4 EM would make more sense to keep the DOC more in range and have a steeper cut entry. Then push the little Tormach as fast as it'll go to make the low end of the SFM table. But yeah I have no luck on a 770 with Titanium or harder with end mills over 5/16. for profile cutting. It just doesn't have the torque or rigidity to make a proper DOC. And with Inconel I'd think 1/4 might be max for a good cut. But you might be able to get into the tool into operating range at least. Nothing wrong with small end mills and lower removal rates if you can make the process reliable. I'd like to see you try it again because I think it's doable frankly.

[@anthonyblythe219]

I'm sure someone else may have pointed this out already... either the ceramic tool pulled out of the holder or the depth of cut was greater than the length of cut. Would be interested to see if it could be done with 1/2 of the loc engagement.

Speeds and Feeds baby: This is the content we crave. Boom

[@phillipmillay8645]

I have a Tormach 770 and only use a mist oil because of concerns about coolant stagnation. If the Blaser 735 sits with out agitation for days will it create a bacteria problem? What cutting performance opportunities am I missing out on by only machining with tap magic applied with a pneumatic misting system?

[@robc2536]

I've been using Blaser 735 on our mill for a while. We only have a spray mist unit and it works fine. I also have 735 in our cutoff saw. No problems with it going rancid without agitation for days.

[@1961muskrat]

What size dia. did the program cut and what did it measure - and measure out of roundness this would be helpful

[@rickyhipsher2896]

I run the 1/2 dia NTK ceramic endmills all of the time on inconel 718 45Rc. I run them at 1300sf X .001 chipload per tooth X 4 flutes X .070 DOC 100% engagement of the tool dia. Works great. For rough out the ceramics are 7 times faster and I get 4 times more parts out of them than a Harvey or a Hanita verimill. Then I use a Harvey or Hanita for the finish passes. They come out beautiful. But those ceramic endmills cost $270 each. Not cheap.

[@Max_Marz]

Ceramic woulda worked, max the spindle, max the roughing feedrate and control the process from there with only the depth of cut, shallow high feed style toolpath.

[@blackburn1111]

Maybe a silly question but do you feel a difference with the crazy nickel alloys and regular tool steels when you hold pieces of it in your hand?

What happened to roughing mills?

[@carlospineda3068]

It's a good starting point. it is a little too conservative of an approach, though. Your MRR is .050 in3/min. I would've started at 1325 rpm, .0026 CL, 1.0"Axial, 20 ipm. That'd be .400 in3/min. still conservative but a cut starting point for a little cutter that you want to use.

[@velvetjones]

Not a machinist but I have a question. They used inconel extensively in the space program since the 1960s so why is it still so hard to work with if they were able to do it 50+ years ago? It seems like something that has been used for 50+ years shouldn't be a huge challenge to work with. I guess I'm asking why the bugs haven't been worked out with tools and machining processes that work around the difficulty of the material.

[@belacickekl7579]

It can (and has) be dealt with a number of different ways, but I'd wager the real production and manufacturing expertise lies in major aerospace manufacturing, where this and other nickel superalloys were made for. They've got more experience with it than anyone else, and can probably mill it without breaking a sweat

[@paulraper7133]

So what was the point of the ceramic?

[@TITANSofCNC]

Will explain it tomorrow:-)

[@danl.4743]

OK, I am embarrassed to show my lack of knowledge, but after the first run of the ceramic, and after the second ran, you said that obviously that does not work. I don't know what you saw that did not work. If I was looking at this, I would be clueless if it is "working" or "not working". Help please? :)

[@JamesChurchill3]

Chips were glowing, heat was building up on the tool and the machine was slowing down indicating it doesn't have the power to keep running the tool at that RPM.

[@paintballthieupwns]

It may have - on the second run the tool sounded ok till it got loose and pulled out

[@shirothehero0609]

When the spindle bogs down (you audibly hear it) basically means not enough hp for the cut. That leads to rubbing and friction and heat build up on the cutting edges and it all goes to hell after that. The shank also started to rub like crazy on the second run - you can see the glowing band grow vertically on the shank. That's def no good. Ceramics are also not 'normal' tools to work with and have a totally different playbook.

[@shirothehero0609]

Also - never be embarrassed to ask questions. It's how ALL of us learn. Anyone who gives you shit for asking questions should get their ass kicked.

You need a better machine to machining hard material like that. Spindle and structure is not enough powerful for this material.

In America maybe you buy a lot HAAS or machines like that, but in Europe nobody buy that. European prefer Japan or German machines.

[@shirothehero0609]

Heat treat - specifically, you mean anneal and then harden again? Your first sentence could be confusing for some (I know that annealing is technically a type/part of Heat treatment, but common usage for understanding typically calls out the specific part of the Heat Treatment process) Heat treating creates hardened martensite and annealing causes recrystallization so the metal is easier to work.

[@alibeyk219]

@shiroskae It doesnt mean annealing exactly as annealing is about 500 to 700'c typically . It's called desolution hardend nano particles which should have done approximately 1300 or more when talking about superalloys. And recovery and recrystallization should considerd in this Process. And u don't have martensite in inconle as there is a lot of Ni,Nb,Ti that are hard gamma stabilizers. I can refer u to some of my elsevier articles if u want to read more.
