Carving

02/07/2017 9:43 AM

Can anyone help me to make a good cnc router for a 3d stone carving? I need a basic size for stating carving works.

Thanks

Soapstone or granite?

3D Router for Stone Carving?... How much thought did you put into this?

That would be a 5-Axis machine... And if your use a Router... what type of cutting bits,... Abrasive wheels... There's going to be a lot of consumables (bits).

It's very unlikely that a volunteer will come from here.

It looks like you have not given this much thought at all. It will take completely different technology to make cabochon or faceted jewelry, Corinthian marble pillars, slate roof pieces, jade sculptures, silicon die or a quartz refractor lens. All of these tasks can be considered to be stone carving.

I thought Corinthian was only for leather seats in Chrysler products?

M. Disdero posted at Wikipedia these Corinthian columns found in Jerash Jordan.

Stone carving has been done long before power tools.

I thought Corinthian was one of a group of books of the new testament.

Two 'books,' actually. Paul's letters to the Corinthians.

These columns (which were still in vogue at that time) are called 'Corinthian' but the style seems to have been invented by an Athenian. According to the architectural historian Vitruvius, the column was created by the sculptor Callimachus, probably an Athenian, who drew acanthus leaves growing around a votive basket. Its earliest use can be traced back to the Late Classical Period (430-323 BC). source

Other, more contemporary sources concur, even if they don't get the naming quite right. According Richard Lederer's Anguished English: "The Greeks were a highly sculptured people, and without them we wouldn't have history. The Greeks invented three kinds of columns - Corinthian, Ironic, and Dork. They also created myths. A myth is a female moth. One myth says that the mother of Achilles dipped him in the river Stynx until he became intolerable." source (well worth a read)

My brother designed and built a CNC 3 axis wood router a few years ago, ~36" x 48" x 12" and I can say for sure it's no small or easy job and that's for a machine works with a comparatively lightweight and rather soft material.

For stone work the framing would need to be heavy steel or aluminum at minimum which then requires all the servos and related motion handling components to be heavy as well and that gets spendy real fast. And that before you even add any software, electronics or tool head and tooling.

So unless your planning to make it tiny and take days to do a single job expect that you are going to invest a huge amount of time and money before you make the first test run. More so if you don't already have the necessary fabrication skills and equipment to build the thing to begin with like a lathe, milling machine, welder and metal cutting saws.

For stone carving, it's a lot more difficult. You would actually need some type of feedback (pressure on the head) for the material taken away. Unlike wood or nonferrous softer metals where you can plow the bit into the material, knowing it will be removed.

Smaller passes creating finer cuts perhaps (assuming the cutting bit and material is of a type that wouldn't chip or flake)?

Really depends on the type of stone, though.

Definitely....one does not want to load up the tool (more than likely a stone). Possibly carbide for softer stone. Still the same, you don't want to load of the tool.

As others have said, it really depends on the types of stone and also the size and required level of detail of the sculpture (although fine detailing could be done by hand). Anything's possible (depending on your budget).

Can you please provide more information?

Pick one out and we'll make a copy....

Do you want a scanner as well?

Did you notice the top 'carving' in both our posts is a toilet?

When I worked at the shipyard, we actually did carvings for Kohler for their proto-types before they got their own CNC router. It was made from some type of plaster.

I know, a rather utilitarian example of functional art, but might be just what the doctor ordered.

It's just as well: the OP hasn't given us a lot to go on.

I would suggest trying this site:

They are much more focused on the maker community.

You might like to join "Instructables" and search on their website, downloading any designs that take your fancy:-

https://www.instructables.com/

They have many CNC designs, maybe one for stone as well.....

Let us all know how you get on!!

Can you stone carve with a laser and air jet? Could you stone carve with water jet?

Could you get stoned and carve stone with a chisel and hammer?

Could ancient aliens have carved the stones at Puma Punku? Did someone punk you?

Do what the Incas (actually their unknown precursors) did.
