How to Machine the PERFECT BALL in a BOX | DN Solutions DNM 5700L Mill 

The importance of a foundation. Making a perfect cube is a challenge to many experienced machinists. Nicely done Barry!

This guy’s presentation and teaching skills equals his engineering skills. Impressive guy.

Barry your a genius. Excellent work, another great example of the integration of subtractive and additive machining. Love you Barry!

we used to just freeze the cube in water, or dip it in wax, then hit the 6th side. we didnt have 3d printed jaws 20 years ago lol

that surface finish when you were squaring the stock is amazing

When I did my ball I used two bottle caps to hold on to the last side. It wasn't the best, but it was the only thing I could think of as a 19 year old machinist.

I never clamp anything offset that much in a vice - it will not be square - at least not in the vices I have. The fixed jaw is fine, but the moveable one will cock. Putting it near the center of the vice, or using a spacer on the other side of the vice will fix it. Evrey vice I have does this. Check yours. If it is still within .002 when clamped this way, then I want one. Been machining for 30 years.

I gotta say Barry, you really know how to put the FUN in fundamentals 😂 #dadjokes

Great work!!! Next video on CNC turners cube plz!!! :D

I've done Turner's cubes where for the final side you tape up the cube with tinfoil tape and then fill it with melted paraffin wax. Let the wax harden then machine the final side. Use a heat gun or low temp oven to melt out the wax. Perhaps not nearly as accurate but definitely still a great result. This video was great and I want to try and make one of these now! Also wondering if two pieces of round stock and a counter sunk set of holes in the ends would maybe work ok for holding the sphere on the final side. 🤔

Ohhhhhh man we have a ton of new information here I like that one when you check the square with v block it so fine and we can save alot ov time with this way Thank you Mr Barry for this video and thank you for your time 🔥🔥🔥🌷🌷🌷 Boom

I'm an optomechanical engineer and I giggle when machinists equate spotless clean with rubbing surfaces with their fingers. It's an interesting relative perspective. :)

Awesome video guys! Is it possible to share the steps done in master cam for people to follow along and Try to make it as well?

The one thing i would love is if you guys had a discord server so we could share info about machining, ask questions, and chat/ hangout. I love the forums boards that are available but my problem is that as new machinist (just about 2 years now) when I post on a forum asking for help I tend to need help as fast as possible. While discord can send notifications directly to your phone if you have the app installed versus going to your email to see whether some replied to you on one of the many forums.

I'm having trouble programming this part. I wish you guys offered a cam tutorial with this.

Work holding and badass cam software

Great! 😃👍

That was a great video, thank you.

Excellent. Now make a solid dodecahedron inside a skeletal hexadecagon. I CHALLENGE YOU.

tenths indicator? lolz!!! love your vids !

La lavorazione in trocoidale per fare la gabbia è eccezionale... complimenti veramente

That is very cool and would make a great conversation piece. Thanks for showing how to do this.

I've done that in wood before on my PowerMatic lathe but wow in metal! Super cool idea on those vise jaws! I need to get a 3D printer anyway...great reason just thinking about not having to machine soft jaws on my manual metal lathe!

Dont know how much mm Tolerance you have But i think the differences in the power of the vice is more important than the 0,02mm in milling faces.

Secret revealed: 10:31 most of he video before that is "how to make a square cube"

Nice Video. DO you know what material Trevor used to 3D print the soft jaws?

Oh yeah, just need a million dollar machine

Very, very cool.

Do you have a link to buy the arm that's holding your indicator at the beginning of the video? Or at least a brand/model number?

cold you make a video of programing this part in fusion?

Hi Titans! Could you make 10 level of shere (cube, dodecahedron) inside one other?

why are there mismatches? how would / should you have prevented them?

Never seen the ball. However I have seen the box in a box in a box.

great job I love it ❣❤

You did not just hitmarker those slaps on the cube 😂

Nice

Cool. What was the depths of cut on the ball? feed and speed?

The 3D printed material has worse tolerance than aluminum due to plastic shrinkage. I also think they should have attempted to use some kind of adhesive on the grip between the plastic and ball

any links to the g-code files by chance? I could figure out the setups. keep rippin!

If I didn’t know better I would say you were throwing down a gauntlet to the community. I do know better and know you want to push peoples boundaries to make them better.. Nice way of doing it. Nice executive stress toy too.

what material were those 3d printed jaws made of?

awesome

Why don’t you use the maximum depth of the material for the sphere?

Is ist posible to get the stl. Or step file of the Jaws?

"today we are gonna defy gravity" Damn someone wanted to sound smart

Why doesn’t some company sell stuff like this, or zero tolerance EDM cut samples??? They could make a fortune!

What about milling a set of step jaws?

why is the vice dial so loose?

challenge ball in box with a drill press & files only

Can you make that ball diameter the same as the cube?

A 3D printer would laugh at this =P

Boom

Skip to 9:00 to skip facing the cube

i thought you were not supposed to use a ball endmill to cut like that since the tip is unable to cut

Can I buy one of those?

เยี่ยม

Need to know the approximate price of that

DESPITE ALL MY RAGE IM STILL JUST A BALL IN CAGE

Who edited this video? I really enjoyed all the little things sprinkled all over it, like the MLG hitmarker. Excellent

the heretical part of me just thought "shrug cut box in half, insert ball, weld box back together, mill welds flush..." but this is much more technically impressive

I guess misalignment would have been in the order of 100 microns. 3d printed mould the weakest link? None the less. this is a cool one. Take it back 50 years and show it around;

I use a ball bearing instead of a half round rod to square up stock.

Great video Barry! And I love how the editors are getting HUGE credit on this one! BOOM!

I use this method for getting some very square (no such thing as perfect) but when I need the best I can get I clamp the part to an angle block, this always yields better perpendicularity.

Man its something else watching this as an european.. Your AMERICAN energy is something else. I dont know why but i have huge respect for this guy and i dont even know him :D I love the accent, makes me want to listen more

And the rest of us just completely fill it up with hot glue ( actually works really well)

I need to try to make one of these before I die, Thanks

I found the edits quite hectic. I wouldve loved to see more of how the machine machined the ball, I didnt know you could make perfect spheres like that!

Would you make and sell this project? How much?

The blocking up is textbook procedure, the 6th step with the 3D printed jaws is cheating, lol, but still very informative and cool, we use hot glue and also go reserved on the depth and feed and speed, then just melt the hot glue away in by boiling water.

You have whole door covering you from hot metal scraps ,in my time working with some ancient equipment i had only my skin covering me from them😅

You guys are badass, period. Just saying. Much love and gratitude.

"Establishment of a Global Commonwealth The imperative(obligatory) of establishing and perpetuating(last forever) the general peace of humankind is a central component of Bahá'í teachings. 

In the latter part of the nineteenth century, Bahá'u'lláh called upon the world's rulers to reconcile their differences and to "lay the foundations of the world's Great Peace." He proclaimed that "The earth is but one country, and mankind its citizens." In doing so, He outlined a number of steps that would lead to permanent stability in international relations. At the heart of His vision was a set of new social structures based on participation and consultation among the world's peoples. These new institutional mechanisms would eliminate conflicts of interest and thereby reduce the potential for disunity at all levels of society. 

A number of international institutions were envisaged: a world legislature with genuine representation and authority, an international court having final jurisdiction in all disputes between nations, and an international executive empowered to carry out the decisions of these legislative and judicial bodies. 

These institutions would have the means to ensure and maintain a general disarmament by applying principles of collective security. They would neither usurp nor suppress the basic autonomy of nations, would safeguard the personal freedom and initiative of individuals, and would protect long-cherished cultural traditions of the world's peoples. 

The system of governance outlined by Bahá'u'lláh(The promised one of all ages, The prince of peace) emphasizes the importance of grassroots decision-making that is democratic in spirit and method, but also provides a level of coordination and authority that makes cooperation possible on a global scale.” “The true civilization will raise its banner when some noble kings of big ambitions, the bright suns of the world of humanitarian enthusiasm, shall, for the good and happiness of all the human race, step forth with firm resolution and keen mind and hold a conference on the question of universal peace; when keeping fast hold of the means of enforcing their views they shall establish a union of the states of the world, and conclude a definite treaty and strict alliance between them upon conditions not to be evaded. When the whole human race has been consulted through their representatives and invited to corroborate this treaty which verily will be accounted sacred by all the peoples of the earth, it will be the duty of the united powers of the world to see that this great treaty shall endure”. “ (Abdu'l-Baha, Divine Philosophy, p. 26) UNIVERSAL PEACE All men and nations shall make peace. There shall be universal peace amongst governments, universal peace amongst religions, universal peace amongst races, universal peace amongst the denizens of all regions. Today in the world of humanity the most important matter is the question of universal peace. (Abdu'l-Baha, Divine Philosophy, p. 26) “This is a new cycle of human power. All the horizons of the world are luminous, and the world will become indeed as a garden and a paradise. .......... You are loosed from ancient superstitions, which have kept men ignorant, destroying the foundation of true humanity. The gift of God to this enlightened age is the knowledge of the oneness of mankind and of the fundamental oneness of religion. War shall cease between nations, and by the will of God the Most Great Peace shall come; the world will be seen as a new world, and all men will live as brothers. In the days of old an instinct for warfare was developed in the struggle with wild animals; this is no longer necessary; nay, rather, co-operation and mutual understanding are seen to produce the greatest welfare of mankind. Enmity is now the result of prejudice only”. (Abdu'l-Baha, Abdu'l-Baha in London, p. 19) “...If the learned and worldly-wise men of this age were to allow mankind to inhale the fragrance of fellowship and love, every understanding heart would apprehend the meaning of true liberty, and discover the secret of undisturbed peace and absolute composure.” [Baha'u'llah (The promised one) - Tablets of Baha'u'llah, p. 162] “The Purpose of the one true God, exalted be His glory, in revealing Himself unto men is to lay bare those gems that lie hidden within the mine of their true and inmost selves. That the divers communions of the earth, and the manifold systems of religious belief, should never be allowed to foster the feelings of animosity among men, is, in this Day, of the essence of the Faith of God and His Religion. These principles and laws, these firmly-established and mighty systems, have proceeded from one Source, and are the rays of one Light.d”. {Baha'u'llah (The prince of peace), Gleanings from the Writings of Baha'u'llah, p. 287}

I might be slightly drunk and have nothing to do with CNC machining... but I admire technology and the art of it. Thumbs up, great vid.

I'm gonna give it a crack, but try with wood first

Sure, you can do it THAT way - but I just get a large ball bearing and cut the cage, soak them both in vinegar overnight, push them together in the morning, rinse and dry. Works about like you'd expect... not at all LOL! But Seriously - Great job with this! (i did put an egg in a milk bottle once in a similar way)

Barry is such a trip. I loved the years i got to work with this guy, he was by far one of the best Programmers i had the pleasure of working with and before he came along my company had never run anything high speed. also his singing about everything he did was classic and his sayings were top notch.

here's a kinda dumb request, do you think you could do the same on a 5 axis mill, doing all 5 sides of the ball in one op then last doing the 6th side, and to compare with the 3axis ball please? (not the cubing part mainly the ball part)

Stepping it up a notch would you do a ball in an octagon that would be cool to see

I would fill it up with plasticine, but using the custom jaws is certainly better.

I've always loved doing tight tolerance work, everyone else always seems to hate it or aren't very good at it but I think it's rather fun. I've always dialed my vises in as tight as possible until my .0001" gauge dial stops moving, if I had a dial indicator that read in .00001" increments I would use that instead lol. My boss always gave me the stuff that we couldn't afford to mess up and had extremely tight tolerances but wasn't in a hurry either, he knew I took my time dialing things in as tight as possible even when I had a mile of tolerance, I was never the super fast get it done in 20 minutes kind of setup guy but he appreciated my attention to tolerance all the same, I even set all my tool height offsets down to the tenth, and would also run every new cutter through a piece of test material to establish my diameter offsets down to the .0001" as well. Takes a lot longer to set up but when your first part buyoff comes around and you've nailed every single dimension down to one or two tenths, it's a pretty good feeling and it impresses the hell out of the inspectors as well.

What is the real benefit of using a "half cut"? It connects on the part by one point due to it's geometry but what kind of benefit does it have? I haven't seen it before.

First😉

If you had your vice a few degrees out of alignment, you would have a wonky looking cube, which would also look very interesting.

Video quality is through the roof today. Love seeing machining on RU-vid!!

Just a 3 axis mill and 2 cutting tools? Damn let me just get mine out of my toolbox.

Is there anywhere to find the model for the cube and the jaws, great project for students to practice setting up

Maaaaan you are perfect what about those super jaws wich you make wow 👌

The ball spun a bit on the last pass. Might want to account for that by making the 3d printed jaws favor gripping the ball by a mm.

That was Awesome! 😎 I want to make that out of copper.

Adding video game sounds for all the new zoomer machinists

As a machinist you should know that nothing is perfect

Thats verry nice🙏🏼

all hail to the video editors! what a great video y'all

"Using nothing but a 3 axis mill" What a humble and lowly piece of equipment you're using ;)

For having the word PERFECT capitalized in the title, and so much time spent on squaring, this video isn't really filled with great advice on making a cube. Don't smack the stock on the first, or second surface. You want the material flush to the vise jaw, not to the parallel it's sitting on. If you smack it down doing the second side especially, you have eliminated your 'guarantee' of it being perpendicular to the jaw... You took a certain 90* out of the equation. Perpendicularity is the ENTIRE goal on side 2, nothing else. 2 perpendicular planes that everything else is based off of. In reality, on a 3" cube, you shouldn't even be using a parallel until the 5th side, and only on the 5th side, and just 1 parallel... Always maximize contact with the jaw to ensure perpendicularity. Then, when you are machining side 4, take a skim cut, with the side of an endmill, 1/4" deep on one of your 2 remaining raw sides, feeding on the Y axis. That gives you an edge that is perpendicular to 2 of the sides. You can then set it on the smallest parallel that you have to skim cut side 5. Just a single parallel, against the fixed jaw. After that, machine the 6th side, and you are done. The dead blow only comes in to play on side 3, 4, and side 6. Providing you jaws are actually square, you will end up with a cube accurate to tenths that way. The way that shown, introduces more opportunity for error. Especially with sketchy starting material. A sphere with a flat against the jaw works better than the half cylinder too. With pretty square material, a cylinder works, but if it's much out of square to begin with, the single point of contact that a sphere provides, guarantees the other surface is flat against the fixed jaw. A half cylinder doesn't do that. The method shown will get you pretty square, most of the time, and very square some of the time. The method I espouse will get you dead nuts, every time, and isn't any more work. (less work in fact as you eliminate setting up the the 2-4-6 block, and just work in the center of the vise, as best practice dictates anyhow)

Fantastic video, I like the longer and more educational ones!

Gente vamos fazer o youtube dominado por JESUS! Cole isso em todos os vídeos que você vê! 💛ELE VIVE💛 🔥ELE ESTÁ VOLTANDO🔥 fixa????????????????

I thought they were going to explain more about the spheres tiny inaccuracies than 5 minutes of making a square box. But ok

How do you make the solid model and tool path in solid works??
