CNC ROUTING

The photograph above shows a 3D mold being cut for a local GFRC company.
From this mold, a casting is made.
A special type of concrete is then sprayed into this "negative" mold yielding a "positive" casting in the appropriate material.
In this case, it was part of a design used for the new TCU football stadium.

Although the sample above was created from a customer supplied CAD file,
it could also have been created from a 3D scan of a physical object.
CAD data can also be combined with scan data.

Below is another example of a 3D CNC carving.
In this case, I created the 3D file based on 2D CAD drawings.
Doing this takes a bit of work but is a common task
when working from architectural blueprints.
You will find this design within Sundance Square in downtown Ft. Worth.

Another good use for CNC routing is to cut out complex 2D shapes
or large quantities of simple shapes which would be very time consuming to do by hand.
While a jig-saw can certainly do the job, cutting curves
can be very time consuming as well as difficult to hold high degrees of accuracy.
Even simple shapes are often best done on a CNC router.
Who wants to cut out six hundred 12 inch circles by hand!?

I have the capability of cutting full 5'x12' sheet sizes.
Although most plywood products are only available in 4'x8' or 5'x5' sheets,
some plastics such as acrylic or Sintra (foam PVC) are available in larger sizes.

Other materials which are good candidates for CNC routing
are HDPE, HDU, Sign Foam, PVC, Delrin, Lexan (polycarbonate), carbon fiber, and UHMW.
There are also many other wood and plastic composites which machine well.
If you do not see the material listed that you would like cut
please send me an email and I'll let you know if I have experience with it.

Below are some examples of 2D shapes (red objects) positioned within 4'x8' sheets (green rectangles).
These are examples of common 2D CNC routing projects.
