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 watch a You Tube movie showing the CNC process of many of the models below.
A wall clock, from mahogany (left) and Oak (right).
The spirals are mostly turning (of a cylinder) on a lathe. If you need hints how the spirals were made on the lathe, consult the two pictures on the right. This table is made from a Beach tree.
Three interlocking Borromean Rings. Three different wood types (Oak, Mahogany, and Eucalyptus). Can you envision how this object was completed? The image on the right is a hint ("when you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth", Sherlock Holmes).
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" and ""Beyond Escher for Real" work. The right image shows the NC simulation on NCSim. Beech wood.
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 of the head of the David's statue. A relief. See NCSim for the NC simulation image.
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 (mostly) CNC (top left), making two half-teapots, and
turning on a lathe (top right) the inside. Beech wood.
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.
The stock from which the earrings were (2mm thick) sliced is shown below. A combination of Ebony, Padauk, and Beech wood. The Ebony was rounded on a lathe.
A wine glass with a knotted neck. The image on the right shows the NC step. Olive tree.
Yet another combination of (very delicate) NC machining and turning.
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 also depicted below.
A gentleman wine glass with a Bow Tie. The rightmost image shows another variant. Olive tree. The images below shows the steps (left to right): the turning, preparation for CNC, and the CNC itself.
A neck formed out of a cross of two (same) letters... Olive tree.
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 below give you some hints how it can be done (wood turning only and no CNC).
Anti-twins wine glasses. Olive tree.
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. Indian rosewood.
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. Indian rosewood.
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. Beech wood.
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.
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.
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) equally spaced 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.
Turning the plate on the right is the easy part once you have the board on the left. However, can you envision how the board on the left was made? The original credit should go to this movie
