CNC pour débutants - Panneau de maison

The design for the House sign was to be quite simple, some strong text and a small graphic to be V-Carved and a simple outline to be profile cut.

I had experimented with a number of extra frills and patterns to add more detail to the piece but after many tries and testing each one in the Toolpath Viewer, I decided that there was some simple elegance to the final design.

It needed to tell visitors the name of the house, nothing more, nothing less.

I had also not decided on the mounting options so this was not considered during the CNC stage.

Once I have set the sign will be mounted on the house, I can add some drill holes at a later date.

I was pleased with the design and keen to get cutting.

Unfortunately I then made my mistake with this project.The piece of wood I was planning to use for this was an old piece of recovered wood, I measured it up and assumed it was a square piece and fixed it to my cutting table. Its actual dimensions were 24” x 23” x 1.25” and I had only measured the 24” and 1.25”. Big mistake and decently one I would regret later. Measure twice, then measure again and cut once!

I designed my part to fill the width of the 24”, generated the GCode and got to cutting. As I got to the N however it was clear I have made a mistake.

With my mistake made, I went back to the drawing board in VCarve Pro 7.5 and used the Design Scaling to shrink the entire job to match then new, smaller, space I had to work with to get my sign into. I then re-measured everything just to be sure this time.

Now with my slightly smaller sign (22” x 8,75”) I got back to cutting and had much more success.

1. Making a note of the XY position before I start, so I can re-zero the bit if needed, always a good idea!2. La gravure en V se passe beaucoup mieux cette fois-ci, le N étant clairement à l'intérieur du bois.

3. Gravure en V terminée, il est temps de changer la fraise !

4. Presque fini, il ne reste plus qu'à réaliser la découpe du profil.

5. Maintenant, le nettoyage final pour enlever les languettes, un léger ponçage et c'est terminé !

En conclusion, j'ai réussi à créer mon enseigne, un peu plus petite que prévu initialement, mais tout de même réussie !

Leçons apprises dans ce projet… Toujours tout mesurer deux fois !
