I program tool paths for helical bevel gears and other more complicate parts in ESPRIT for our HAAS 750 for almost 2 years now and your videos still teaching me lessons how to do proper, nice to watch, toolpaths. Thank you.

Here's a guy who knows what he's doing!

The comments about the ballnose cutter cutting on an angle was interesting to me. I use a lot of ballnose and tapered ball nose cutters on my 3 axis cnc router, and now I'm thinking I should increase the RPMs. Unfortunately I can't change the angle, but realizing that a ballnose is effectively a very small diameter tool in those situations may help me out!

I've watched your videos for years. youtube stopped showing your new videos for me and i couldn't remember your channel name but I finally found it.🔥🔥🔥

Always an interesting part getting machined never boring.

I saw in a book once a setup to mill a helix on a manual machine it was quite the deal to do manually. CNC really shines on a job like this.

Work of art.

I love the camera angles! And the explanations and simulations are very interesting. Thanks and have a nice day .

Looks good. Always impressed with you attention to details.

Hi Edge, your knowledge and experience are amazing, even though I have very very little cnc experience, equivalent to Zero....I am enthralled by the things you machine, best wishes from an old guy in Florida, Paul

Awesome video and part! Thanks for the Esprit content! I was one of the ones that asked. I really enjoy hearing you discuss your machining strategy.

Just incredible work as usual Pete, thanks for sharing 👍👌🇬🇧🇺🇸🇺🇦

11:25 a good way to think of this is that the center of the tool is traveling nearly zero linear distance per revolution. Think of it like standing on the very center of a merry-go-round. This means that the chip load, no matter what the feed rate, has the tendency to explode to infinity. The absolute center is removing infinite material relative to its linear surface footage. There is also, as you mentioned, the issue of recutting the chips. Those fines will act like sand paper. We use some CNMG inserts for heavy roughing on 1040 at my shop. We are taking .130 DOC at ~.025 IPR. There is a brutal interrupted cut in the middle of the roughing. The inserts last about 35 parts with high pressure coolant, and 50 without. My theory is that it's the thermal shock induced during that interrupted cut, and the coolant makes this worse. In addition, the Sandvik inserts we use seem to behave better once the coating has some heat in it. In light cutting applications like this, I think about it like the process of burnishing... The metal has to be warm to be nice and ductile so that the tool and workpiece slick past each other. Im a junior machinist, still learning and I don't know a dang thing. Please let me know if there's anything I am thinking about incorrectly.

Very cool, in a twisted kind of way. Nice work

This is just soooooooo amazing. Man this really makes me dream big.

Nice work dude 💯 I think you could program that with a subroutine, at least the roughing. I have been doing that using incremental H commands for the rotation angle instead of C. The coolant causes thermal cracking of the carbide because the insert is engaged in the material for that split second and isn't getting coolant until the chip curls away, and then it is exposed to the coolant again and rapidly cools. Like you said, it's better running dry with air blast maintaining a consistent temperature at the cutting edge. I get at least 4 times the tool life running dry like that. I also have a Mitsubishi index-able I use for steel, VP15 grade I think, it kicks ass.

What it is I have no idea but it'd make a nice conversation piece. Thank you as always for the insight.

8:56 that camera angle maaate, that is awesome

Un vídeo más mostrando trabajos excelentes, donde se ve la experiencia, gracias por compartir!

Thanks for sharing as always. Tricky part with the ball endmill…

That's a cool looking part!

Great video, great part!

Thank you for your time 👍

Excelente trabajo. Maestro.

Amazing Peter! I think you get work that everyone else "No Quotes"

Beautiful piece. Would make a great door stop.

Superb work,

Outstanding....

Great job as always! I’m quite certain this is used as a downhole drilling tool. If so you are correct that the reamers (ribs) will be hardfaced with tungsten or something specific to the conditions of the well being drilled.

Thanks, lot of useful info here

that part looks like a Sinusoidal Turboencabulator

Very nice machine 👍👍

that is a sweet looking pattern that roughing pass left.

very very good video Peter

This would be a good job for circle segment / accelerated finishing tools.

Great video. It's really great to see somebody doing similar work. I also use ESPRIT and helical flight part but contoured so no flat bottom face. But we are limited to a VNC535 with rotary. Hopefully, we can get some intergrex 200 soon! Is the wall a vertical 'ish'? Look into the free form scarf cycle with solid EM. Maybe get more consistent finish side to side, possible cycle time reduction.

Nice vid as always :) Have you ever tried running a program from the HDD directly? I’ve run a 3 axis mazak with the 640M control and if your had a program on the HDD, you could run it using Tape mode instead of memory mode, I think you need to use a program number that’s not in memory for it to work. Also a disadvantage is that you can’t see the current line the control is on as it seems to kind of drip feed it internally. If you do it correctly you should get a red HDD (I think) icon in the bottom right corner of the screen next to the green TPS(I think again, it’s been a while :) ) Thanks for the great content

Just as an FYI if you didn't already know, you can put a main program in the machines memory that just has an M98 with the program number of the actual program you want to run and it will go grab the main much larger one out of the hard drive of the machine with the actual toolpaths which is much larger and run it that way. I do it all the time with my 15+ MB surfacing programs that I want to do all at once in my 2MB mazak controller. It does not seem to affect the reading speed of the code at all and lets you fit extremely large programs and run them all at once

I get the feeling if I did a job like this I would constantly break everything. tools, machines,parts myself!!

Awesome thank you. What B Axis angle did you use to surface the flutes with the ball end mill ?

TECHNOLOGY IS GREAT

the axes of the machine must be treated and the b-axis must be straight. Otherwise the surfaces will not meet and there will be stairs. Wonderful work.👍

Have you tried the Helical, or similar, lens form end mills? I tried some a couple weeks a go, it was super nice to have a 1/2" tool with a 1" radii lens tip.

B axis work ain't cheap, drillers only ones that can afford it.

I agree with everything except taking finish cuts without coolant. I run all milling tools "dry" with AIR blast and finish using coolant. Maybe with that particular tool you have or something it doesn't work well, but otherwise in every single scenario I run coolant. If you try to run feed mills or high speed machining (profit milling in esprit) without good air blast, the amount of heat generated breaks down the coating on the inserts and they fail. At least that's been my experience

Hello mr Peter . Nice flutes . Can we get a short video on the Hotel project update ?

What kind of software you are using? PS: thank you for choosing Poland chuck :)

Hello. Very informative. How would you approach an internal cut of this? Thank you

Would a foot of extra stock on the blank - to improve access - help? For a part that involved surely the cost of it would be marginal.

Question, on the opposite problem wall surface, the operation made the ball tool almost perpendicular to the surface, using the tip of the ball as you stated, isn't there a setting or process that would have made the tool perpendicular to the cylinder, or turning axis instead, and then allow a slight offset setting from that. Just curious.

Does the mazak control use G12.1 (polar interpolation) to interpolate the c and y axis? And possibly show some of the g-code?? Thanks ive learned a lot from your videos.

just what kind of machine/jobs uses a end mill thats over a foot in diameter?

About the collision problem, do these machines not have safe limits? I run an Okuma lathe, and it allows you to simply set a limit to where the turret is allowed to go, and it will not go any further than that. Mind you, I've never worked with Mazak or, sadly, with one of these lathes with a milling head, so I might be completely off here.

I want this job

Can you show the code for the wrap milling portion just as an example?

Sangat hebat

Flute Peter

Hey Peter, gotten any news on the retirement place? Time frame yet?

Another oil tool part. Lol!!! Stabilizer sleeve for something....

Do you think the Mazak was your last Mashine? How about a new one? :)

Howdy Peter, How much does this machine weigh?

How you measure a endmill ? If its not full diameter? Like 7.8 mm. ?

This can also be done on a manual machine

Oh there's other lonely Esprit 20XX/TNG/Edge users out there watching 😉

Ahhhh yes, the machine's memory capacity. We own a small 4-axis Mazak, which has 8Mbs of memory after it was upgraded from 2Mbs! With modern 3d adaptive strategies it is far too little. I do not understand why is it such a problem and why a controller worth like 20k USD does not have let's say 1Gb of memory? It's ridiculous!

How are you liking Esprit Edge for Millturn? We've been struggling to transition from the 20XX series to edge due to under developed factors in our specific machines.
