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 watch a You Tube movie showing the CNC process of many of the models below.

A Round Table

One can only guess how these legs were made.

Spiral Shelves

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 Fagus tree. The second table (right two figures) was made from mahogany and (glass:-).

Penrose Triangle

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.

These bottom two images show snapshots of the NC process.

David Star Cup I

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".

David Star Cup II

Here is another variation of this model, this time from an Olive tree.

Symbiosys of the Jewish David Star and the Islamic Crescent Moon Symbols

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.

Candle Sticks

A combination of NC machining and turning. The image second from the right shows the NC setup while the right image show the final NC part before turning.

Shoe Knots

Yet another combination of NC machining and turning. The image on the right shows the NC step.

Lettered Necks

A neck formed out of a cross of two letters...

Wicker style Vessels

Wicker style tops for wood (olive tree) vessels. The left image shows the CNC stage.

2 Cones

Two cones turned on a lathe, sliced and glued together...

Vase with Round Arcs Markings

Another combination of NC machining and turning. The image on the right shows the NC machining stage, on the turned blank.

Vase with a Square Neck

The square section neck of this vase was created using NC machining. See image on the right.

Vase with a wiggled Neck

The wiggling neck section of this vase was created using NC machining. See image on the right.

More variations of wiggled/Omega Neck's vases

The wiggling neck sections of these vases were created using NC machining.

A knot neck's vases

The neck in the shape of a simple (not a) knot. The NC process is also depicted.

Vases with a Helical/Hollowed Necks

Both vases (glasses!?) are the result of some addition carving. No CNC this time...

Inside out turning

Turning only to flip inside out and turn again,,,

Side turning

Turning the wood on the side. The right example is using Olive tree.

The Utah Teapot


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).

Israeli Flag Pen

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 site

Sine Wave Patterns

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.


David's Head Relief

NC machining of the head of the David's statue. A relief. See NCSim for the NC simulation image.


Some Bowls

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.


Diamond holes. Left image shows the CNC in action.


A Bowl with winged holes. Left image shows the CNC in action.


Another Bowl with winged corner holes. Left image shows the CNC in action.


Eucalyptus


Wood from a stock Tom Hunt, Seattle sent me (Tom, what wood is this?).


Some winged vases with natural bark


Same Vases

Indian Rosewood

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.


Yet another combination of turning and NC machining, of a vase and its cover. The images on the right shows the CNC process.


Another Relief - Boeing's logo


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 NCSim

Segmented Turning

A simple attempt at segmented turning.

Some more examples





two sides of the same parts!
