What is CNC Machining?
CNC stands for computer numerical control. So, CNC machining is any kind of machining process controlled by a computer. Computerized automation allows parts to be made more quickly, accurately, precisely, and with more complex geometries than those produced via manual machining. CNC also reduces manual machining labor that would otherwise be done by humans. While they aren’t machining each part themselves, people are essential for programming and operating the machines, ensuring that every operation goes smoothly.
About the CNC Machining Process
CNC, or computer numerical control machining, is a subtractive manufacturing method that leverages a combination of computerized controls and machine tools to remove layers from a solid block of material. The desired cuts in the metal are programmed according to corresponding tools and machinery, which perform the machining task in an automated fashion.
Types of CNC Machining
Depending on the type of part that needs to be machined, there are different types of CNC machines best fit for the job. CNC milling utilizes CNC mills, which consist of a multi-axis system (three, four, or five axes, depending on the part complexity). CNC turning involves Lathe machines, which generally have two axes and cut pieces using a circular motion. Electric discharge machines (EDM) utilize electrical sparks into order to mold work pieces into the desired shape. Hobbing is another type of machining process used for cutting gears, splines, and sprockets. Additional CNC machine types include plasma cutters and water jet cutters.
How Does CNC Machining Work?
The programs used for CNC machining these days are written with G-code, and are usually automatically created by CAM software. CAM, or computer aided manufacturing software, generates the G-code for a 3D model with given tools and workpiece material. This G-code controls the CNC machines, i.e., the motion of the tool, the workpiece, and any tool changes. It even has commands to turn on or off the coolant and other auxiliary components.
CNC machining can be used for a wide variety of materials, with the most common being aluminum, steel, brass, ABS, Delrin, and nylon. But really, almost any hard material can be CNC machined. We’ll discuss the materials more in-depth later on.
CNC vs 3D Printing
Compared with parts manufacturing through additive methods, CNC machined parts are functionally stronger and typically have superior production quality and finish. Thus, CNC machining is typically used in the mid to late stages of development when parts are ready to be tested for functional accuracy.
CNC Design Considerations
While most of the details, such as tooling, spindle speed, cutter type, and depth of cut, and taken care of at the machine shop, there are some key things you can do while designing your parts to not only make sure they can be made but also ensure you develop a lean product that doesn't break the bank.
The primary advantages of CNC machining include rapid prototyping and the ability to produce full-scale production parts quickly. It offers a high level of precision and accuracy in manufacturing parts and allows for tight tolerance machining for CNC parts of all sizes. It also offers maximum flexibility across volume, pricing, lead times, and the range of materials and finishes being used.
The two primary CNC machining processes are CNC turning and CNC milling. Other machining processes include drilling, gear hobbing and electrical discharge machining, among others.
Industries that use CNC machining include aerospace, automotive parts manufacturing, medical machine manufacturing, transportation, defense, and marine industries, along with oil and gas industries and electronics. CNC machining has allowed these industries to become more efficient at mass-producing custom CNC parts.
The standard machining tolerance is ± 0.005" or 0.13mm. Tolerances are the allowable range for a dimension. If a CNC machining tool has a tolerance of ± 0.01 mm this means that the machining tool can have a deviation of 0.01 mm in every cut. With a drawing, Fictiv's CNC machining service can produce CNC parts with tolerance as low as ± 0.0002 in. Without a drawing, all CNC parts are produced to our ISO 2768 medium standard. We can also machine to tighter tolerances, ±0.025mm or ±0.001", with an attached engineering drawing calling out critical features.

Answer to “Why?”: This is a 3D printed ship that actually floats. If it was milled out of a solid block of plastic, the waste would be very excessive. 3D printing it minimizes material by adding material to get the shape of a boat. The CNC smoothes out the layer lines making the ship have less drag when going through the water.
I think the why for most is “why not injection mold this?”
@@PrintFarmer if you build only minimun number for test or prototype its have less cost then injection mold when mold made frome cnc aluminum
@@PrintFarmer injection molding at such scale is extremely expensive. If a small idk say bottle cap steel mold is $10k then how much a boat sized mold be :D
If they are producing millions of those boats. It's definitely worth it, because it would cut down time so significantly and disperse other costs so thin, they would basically only pay for raw materials. But if it's a batch of 10, then milling and printing is the bestest way to go.
@@PrintFarmer Rapid Prototyping
@@PrintFarmer you would have to design a machine that is currently non existent and would make the biggest injection molded object is the world. So if you like a 1000000 dollar dingy than that would be a good option
That's how it's done.
No need to make a mold. No machine for injection molding on that scale needs to be build. No need to mill away 90% of a solid block of material. Just a tiny bit to get a nice smooth surface.
Was this done at UMaine? I remember them 3D printing full sized boats
Rapid iteration on a grand scale.
Q: Why would you CNC mill something that has already been 3d printed?
A: Because as expensive as CNC machining can be, 6,000 gallons of filler primer to fill those layer lines is still more expensive.
Because we love microplastic in the environment.
This footage is mesmerizing!
That's a nice additive application
О, да. Божественная 5ти координатка❤
А главное идея огонь, печатать со 100% заполнением потом фрезеровать совсем немного, для повышения точности геометрии, если не быстрее, то дешевле чем из бруска фрезеровать. Надо применить на практике.
Finally I’ve made it to the most bad ass of cnc on RUclips
And that material is abrasive as fk and will wear your carbide. Even though its plastic. Mad.
Where both Technologies of the old and new meet..
A gracefully collaboration of machines, minds, materials collide...
Into a cataclysmic event of wonder.
😂
Looks like they are making a plug out of a foam, so that they can make a mold out of it and only then get a hull out of the mold
Best cnc
That is wicked cool
What would be the cost of this ship compared to other plastic or wooden ships...
Expensive, very much not worth it
@@Coastal_Cruzer you think this costs more than a crew of carpenters and fiberglas layers, including material? I don't know the real answer, but it seems to me people would cost more. Compared to injection molded boats though, I agree. This is more expensive, but it's probably just for prototyping.
@@charlesstaton8104 time is money and printers take ages on small scale stuff, no less something this large. Maybe not as expensive as a wooden boat, but fiberglass, metal, and cast plastic boats would all be cheaper to make. And i guess the prototyping thing kinda flew over my head even though that's like the best aspect of 3d printing.
@@Coastal_Cruzer Until you realize that this is the exact model they had in the computer and cam make slight alterations that might save millions or more once this ship is made in full size, models are expensive before production but worth every penny
@@Coastal_Cruzer Fiberglass and wood might you get you close to being exact but not at a level this process will
You can't download a car, but you can a boat.
??? Why not milling directly ???
What type of tooling/bits are you using?
How the hell do you line/set that up for milling😮
3D scanning and alignment algorithms
I’m really curious the overall cost of the project. Both 3D printing at that scale + milling. I’d love to create/sell my own boat designs, but I don’t have the team to actually manufacture them.
Just guessing from my knowledge of current printing technology, but this would need to be a fully custom printer running pelletized plastic with a gantry that include all 3 axis. Depending on if you design and build it yourself, or get the parts from someone else and build it, you'd spend $15-20K on the printer. That's guessing on the low side for a super large FDM printer. The 7 axis CNC new starts at $40k.
@@jameslmorehead Yeah I mean that probably just scratches the surface. There's the whole implementation of those tools and learning how to use it. It's probably best to have an expert technician that operates it, and there's their cost to add to the project. I'm sure there's quite a bit extra cost involved.
This was printed and machined on an Ingersoll masterprint. It's a building size (100x20x10 ft) multi-million dollar machine.
this ship is 20 meters long
What material is the 3d print out of?
I saw another video of a boat being printed in polymer so that’s would be my guess
@@ThisIsMyRUclipsHandle69 Every single plastic is a polymer
@@anibal5824a single plastic is a monomer.
@AlexCell33 No, a monomer is the repeating unit of a polymer, you can't have a polymer without a monomer.
That's oil modeling clay, usually the rough is sculpted by hand not with 3D printing
❤
Is it still considered 3D printing if it's milled out?
Yes. It was 3d printed then milled afterwards for better finish.
Yes. All 3D printed parts require finishing of some sort. This is just on a larger scale.
@@sferrin2not necessarily, especially if you design the model well
@@HarryPorpise for a lot of professional applications, the 3D printed finish is too rough
Amazing if can buy this boat
Только это не 3д принтер это 5 координатный фрезер
You are confused. It is 3d printed and the machined in the 5 axis CNC afterwards.
@@kentl7228 напечатан на принтере. А на видео фрезер 4-5 координатный.
Perhaps translation is the problem for you...
The title is saying that a CNC device is machining a boat that was 3d printed previously.
@@kentl7228 да спасибо что поправили меня. Действительно английский не любим мной.
@@Zaebzhe Без проблем, мой русский просто мало и ваш английский просто мало )
Full video please
All I could find: ruclips.net/video/vZw9jaDt_hI/видео.html
Jobs machine?
What kind of CNC is this?
A big 5 axis mill id guess.
But no idea what brand or model
a very expensive one!
looks like an SNK
Se tardaria mucho menos con un molde por injeccion ,no tiene sentido 2 dias imprimiendo y otro mecanizando....hay veces que no es viable....
Is there any way for college manufacturing students to get involved?
Why
They don't sell plastic blocks this huge (or at least that I know of) to carve it out of. Also adds less waste
Seems like a very expensive way to make a boat.
why would you not just mill everything then?
I assume you're getting a good finish from milling, while not wasting all the time and material it'd take to hog out a large block
-Machine costs
probably faster this way
Where to get a solid chunk of plastic that big and why waste most of it?
For the same reason that every machined metal part is not machined from solid billet as well. Even with metal parts they will forge a slightly oversized piece and machine it down to spec. It saves machine time, material and costs less.
🚄😊😄☁🌙
I wouldn't call that giant
What's the point of this?😂 kind of defeats the purpose.
The point is that you only have to remove a small amount of material to finish it as opposed to milling the whole thing out of a solid block
@@elanjacobs1 ships aren’t milled out of giant blocks lol
Prototyping
Reducing drag and getting a better surface finish. Probably gonna be a mold for fiberglass.
@@roscoe4092 That's why they aren't solid and 100000% waterproof ;)
