Some Turning/Wood Working Examples
Most of the work below is the result of using my lathe and my small
3-axis NC (Numerically controlled) routing machine. The NC code was
solely developed with our own software tools. I use the IRIT solid modeling
environment to create the G-code (the NC tool path) and NCSim to
simulate and verify the code before I actually cut. You can also
You Tube movie showing the CNC process of many of the models
One can only guess how these legs were made.
A wall clock, from mahogany (left) and Oak (right).
Another one that is mostly turning on a lathe. If you need hints how the
spirals were made on the lathe, consult the middle two pictures. The right
two pictures shows another variant of this table (in combination with
some glass). The first table (left four figures) is made from a Beach tree.
The second table (right two figures) was made from mahogany and (glass:-.
Penrose triangle is a very well known so called 'impossible' shape.
Try google it. This specific variation of the penrose triangle is part
of my "Escher for Real"
""Beyond Escher for Real"
The right image shows the NC simulation on
NCSim. Beech wood.
These bottom two images show snapshots of the NC process.
Here is a variation of the David star using two intertwined Penrose triangles. The CNC in action is shown on the right. See also ""Beyond Escher for Real". Gaboon wood.
NC machining was used to cut the David Star shape at the neck. The rest
is regular wood turning. The image on the right shows the NC setup. The
David Star is actually formed out of two intertwined Penrose triangles.
See also ""Beyond Escher for Real". Indian rosewood.
Here is another variation of this model, this time from an Olive tree.
Here is another variation of the david Star. Herein, the Jewish David
Star is shaped to look like the Islamic Crescent Moon symbol from the side.
As a result, this model presents the Jewish David Star from one view and the
islamic Crescent Moon from another. The image on the right shows the CNC stage.
Three examples of bowls with a top david star curved out. Top row shows the final piecese while bottom row shows snapshots of the CNC in action. Indian rosewood and eucalyptus.
An example of a spherical bowl with a heart outline on the top.
On the left is a snapshot of the CNC in action. Indian rosewood.
Examples of small wooden buckets with wooden chains, built from one wood block
(Indian rosewood). The image on the right depicts the CNC step.
A combination of NC machining and turning. The image second from the right
shows the NC setup while the right image shows the final NC part before turning.
More combinations of NC machining and turning. The images on the right
show the NC setup. Olive tree.
Yet another combination of (very delicate) NC machining and turning.
The image on the right shows the NC step. Indian rosewood tree.
A wine glass with a knotted neck. The image on the right shows the NC step.
A vase being held by two hands. A combination of NC machining and
turning. The image on the right shows the NC step. Olive tree. The
geometry was creating by deforming a 3D model of a hand using a
geometric modeling technique called freeform deformation that uses
trivariate splines. Olive Tree.
A neck formed out of a cross of two (same) letters...
Wicker style tops for wood (olive tree) vessels.
The left image shows the CNC stage.
Two cones turned on a lathe, sliced and glued together... Indian rosewood.
Another combination of NC machining and turning. The image on the
right shows the NC machining stage, on the turned blank.
The square section neck of this vase was created using NC machining. See image
on the right.
The wiggling neck section of this vase was created using NC machining.
See image on the right.
The wiggling neck sections of these vases were created using NC machining.
The neck in the shape of a simple (not a) knot. The NC process is also
depicted. Olive tree.
This time the neck in the shape of a more complex knot (so much so that I
decided not to disconnect two joins if you can see them). The left is
from olive tree and the right in Indian Rosewood. The NC process is
One can turn one captured ring on a wine glass. One can turn two
captured rings on a wine glass. But can one turn two wine glasses
captured in a single ring? It is doable but the version you see
here is only a partial proof - the ring here broke in the process and
was glued back in... The three images on the right give you some hints
how it can be done (wood turning only and no CNC).
This segmented turning piece (a combination of Mahogany and Oak) is
created one layer after another, using a Jig that divides the entire
circle to 24 parts. The Jig is made of simple 24 170mm radius lines
(12 340mm diameter lines) around the circle. You can find the CNC
G-code for this one here (the cuts are
done in 4 mm deep zigzag motion in Z to a total depth of 8 mm). Note the
dividers in the Jig can be taken out to create a division of the
circle to 12 (as is the case for the first layer in the final piece),
6, 4, or 3 parts.
Anti-twins wine glasses. Olive Tree.
Both vases (glasses!?) are the result of some addition carving. No CNC
Turning only to flip inside out and turn again,,,
Turning the wood on the side. The right top example is using an Olive tree.
The bottom one is from a Carob tree.
Several variation of a nut cracker, using a nut cracker gadget that looks like
a steering wheel of a boat... Mahogany (top two pictures) and Carob tree
As one of the most famous models in computer graphics and geometric
modeling, here is a wooden version of the Utah Teapot. Yet another
combination of CNC (top left), making two half-teapots, and turning on
a lathe (top right). Beech wood.
This is a pen kit I received from a great friend, Tom Hunt, Seattle,
that helped me diving into this fun turning hobby. You can purchase
this pen kit from this
Another pen I turned using a blank that is formed by two differently colored
wood parts cut into complementary sine wave pattern and glued together. The
sine wave pattern was made using NC machining.
NC machining of the head of the David's statue. A relief.
for the NC simulation image.
These bowls are from an Indian Rosewood (Dalbergia sissoo) tree.
Any clue what wood this is!?
Banana holes. Left image shows the CNC in action. Indian rosewood.
Diamond holes. Left image shows the CNC in action. Indian rosewood.
A Bowl with winged holes. Left image shows the CNC in action. Indian rosewood.
Another Bowl with winged corner holes. Left image shows the CNC in action. Indian rosewood.
Wood from a stock Tom Hunt, Seattle sent me (Tom, what wood is this?).
Some winged vases with natural bark
Shoe knots, with real shoe laces...
Another combination of turning and NC machining. Carefully inspect the
cross sections! The image on the right shows the CNC process. Indian rosewood.
Yet another combination of turning and NC machining, of a vase and its cover.
The images on the right shows the CNC process. Indian rosewood.
Another relief using NC machining of NC (G-) code I received from a dear
friend in Boeing, Tom Grandine. The top right image shows the NC simulation on
Victor Vasarely (1906-1997), the `father' of OpArt, produced several
pictures in which nearly parallel black stripes on a white background
bend and deform locally to produce striking Gestalt 3D effects.
Inspired by Vasarely's art, in this work we produce a 3D wood version
of two such emblems combined together in 3D, Israel's Menora and the
david star, that are coming to life independently, from two different
viewing angles. Made off sequoia tree, and combined wood turning and
CNC work (left image). Thanks go to Uriel Bareven that helped
slicing this stock, from Sequoia.
A simple attempt at segmented turning.
Earring. The stock from which the earrings were (2mm thick) sliced is showned on the right. A combination of Ebony, Padauk, and Beech wood. The Ebony was rounded on a lathe.
two sides of the same parts!
