Our high tech CNC routers can machine in 3 axis which gives us the ability to machine any type of 3D surface. 3D surface machining is a lot more complex but allows you to make some amazing things, from a simple curved surface to complex moulds and patterns.
The benefits of CNC 3D Carving
Repeatability, same parts everytime
Time saving when compared to hand carving
High surfaces finish helping to eliminate hand finishing
Unlimited model designs and scale
Multi layer or sliced models can be made
Why range of materials can be machined
Common parts made by 3D carving
Bass relief (shallow cutting)
Moulds / plugs
Detailed signage letters
Complex curved surfaces
3D Wall Panelling
How does it work
The 3D carving process for making such items can range for a pretty easy set up right through to very complex multiply set ups with multiply tooling and layered sliced reliefs.
In all cases you first need the 3D model itself this can either be supplied by the customer or we can buy or create one for them for you , creating a complex or highly detailed 3D model can take a lot of time to do a good example of this would be the game of thrones doors we did, each 3D design took days of work just to create the 3D model never mind actually manufacturing it so this can be an expensive part of the process
Once you have your 3D model you then need to import it into the machine software where you do the initial set up work and add the positions and toolpaths to cut it out
Image showing the red lines these are the toolpaths the machine will use to cut the material
Model above has been imported and
set up ready for toolpaths
Once you have applied the correct set up and toolpaths to your 3D model you then send all the correct data and toolpaths to the CNC Router, you are now ready for the machining process.
Machining process is pretty simply as you have already done most of your set up work in the computer you just need to make sure your material is secure, safe in the correct position, make sure your machine origin on the CNC is set right and that you have set up the correct tooling in the correct positions once you have these factors right you are ready to start machining.
3D carving in general takes a lot of time especially with fine detailed models the finer the detail the longer it takes to machine because you need small sized tools to get those fine details and it really is the fine details that make all the difference in these especially bass relief panels like those game of throne doors, example the GOT Doors took 50+machine hours just to carve out so 3d carving is normally pretty expensive.
You typically machine the 3d models in 2 passes one roughing pass to remove excess material and then a final pass to get the smooth and detailed finish.
Your roughing pass should be done as quick as possible to speed up the process and to save the customer money in machine time, but make sure you do not break off any of the material especially in wood as this is very easily done , make sure you set this up correctly in your toolpaths and by not going at the material too hard.
Picture above used a large ball
nose tool for rough pass with offset command
ONCE ROUGHING IS DONE DO YOU FINISN CUT NORNALLY WE USE A 1MM TO 3 MM BALL NOSE JUST DEPENDS ON FINISH AND RETAIL REQUIRED
