Videos   >>   COA: machine a Coat of Arms relief in wood


Coat-Of-Arms relief videos and files.

This great Coat-Of-Arms relief has been created by Todd Bailey of 4M3D logo as a custom model for DeskProto. We supply the model as a free download, hoping that machining this relief will make you appreciate the DeskProto software. Note that you can easily customize the model by adding graphics and text to the shield and the ribbon, as explained in the Tutorial videos below.

The relief is available for download in two versions:
The file dpshield-flat-stl.zip is a 22 MB file, containing a 35 MB STL file of the relief with flat shield and ribbon surfaces, to be used with DeskProto Lite.
The file dpshield-domed-stl.zip is a 22.5 MB file, containing a 36 MB STL file of the relief with domed (curved) shield and ribbon surfaces, to be used with DeskProto Full (in Lite it is not possible to project 2D toolpaths and bitmap toolpaths onto a domed geometry).

Creating toolpaths for a Coat of Arms relief, customized with your own graphics and text.

The Coat-Of-Arms relief video (part 1) shows you how to create toolpaths for a complex relief geometry (a Coat of Arms), using DeskProto Lite. Part 2 teaches you how to customize this relief by adding your own text to the ribbon and your own graphics to the shield.
As the geometry of the relief is a free download, this lesson enables you to create a model for any purpose that you feel suited.

Machining the Coat-of-Arms relief in walnut wood:
using toolpaths as created in the tutorial video above.
Video that shows machining of the Coat of Arms relief in walnut wood.

The Coat-of-Arms video shows plain 3-axis machining, for a detailed relief geometry. Even more as details are added using bitmap operations and a 2D operation.
The four steps that are shown are:
Roughing, 6 mm ballnose cutter
Semi-finishing, 3 mm ballnose cutter
Finishing, 2 mm ballnose cutter
2D text engraving, 1 mm flat cutter.

In this project the bitmap machining is not an extra step: as the relief is lying on top of the shield, all operations need to be bitmap operations. This in contrast to the Tutorial video above, where the relief is later engraved in the shield surface.
The relief is machined in walnut wood: looks great !
Take care though as walnut wood dust may cause allergic reactions.

These first two pictures show a small version of the flat Coat-Of-Arms relief (140 x 150 x 20 mm), made using DeskProto Lite as described in the video tutorial. A base has been added below the relief by loading a second STL file into the same DeskProto project. The bitmap relief is 'negative': has been created by removing material after first machining a flat shield. The model is machined in tooling board, you can click on the left picture for a high-res version.

The second Coat-Of-Arms is larger (230 x 220 x 11 mm), however machined without the base. This model has been machined in walnut wood, using four different cutters: roughing with a 6 mm diam ballnose, after that a 3 mm ballnose, and finally a 2 mm ballnose. All these toolpaths have been created in DeskProto Full using Bitmap operations. That was needed to create a positive relief, lying on top of the (domed) shield. The text finally was engraved using a flat cutter of 1 mm diameter.

The resulting model has been treated by special wood-oil and looks great !

We could not resist to create a third Coat-Of-Arms model, machined in the back side of a transparent material. Much smaller this time: ca 65 x 65 mm. The shield geometry has been converted to a cavity by selecting Inverse milling in DeskProto. Note that inverse milling will come with a 180 degree rotation, which also has to be applied to the bitmap and to the 2D text on the ribbon.
The picture on the shield is the Radetzky bitmap (Austrian fieldmarshall Radetzky) that is one of the example files in every DeskProto setup.


Machined in wood
(beech and mahogany)

The back side shows that a cavity has been machined.

Thiele Holz from Wurzen (Germany) produces wooden articles and artworks. Herr Thiele machined the Coat-Of-Arms relief for his own use: the letters A.R.T. being initials.
The relief model was done using DeskProto, without 2D operation or bitmap operation. The letters were separately machined, using 2D toolpaths, and have later been glued onto the relief model.




Do email us a photo of the Coat-Of-Arms model that you created so we can add that to the list of results !
(in case you want with a link to your website).
We do look forward to seeing what graphics and texts you will be using with this relief, and for which applications it will be used.
