Tree in MDF

posted in: Machining Projects | 6

Once you do a couple of jobs in Vectric Aspire, you realize how easy it is to plan a 2D machining. As I take every opportunity to machine things, my wife needed to take a stand to show their handmade jewelry, searching the internet and saw an interesting idea: A tree from MDF. If you want to see which is used in this link you can access the blog in question

Thus, I set to work, and end up realizing that the process is very simple, and the result is really good:

First, obviously, the CAD drawing of what you want to do. As you know, I have enough experience in SolidWorks, so I draw fully in this program. The idea was to make the tree into three pieces that will fit two louvres and a circular base.

Once the CAD is finished, I have to pass all three parts separately for DWG, or DXF, or any format that targeted Vectric Aspire can recognize. I personally have first passed through Autocad simply to organize three pieces, place them so that they occupy as little as possible, and group all the lines.

(If you’re interested in the CAD file, you have it available in the Downloads section)
When opened in Vectric Aspire, this is what you see:

When we loaded the vectors, prepare the tool paths, and this is also very simple. In Vectric Aspire, we have to select the tool that we use, then the vectors in which the trajectories will apply. In the selection window of the tool, we can set the depth of past, the speed, etc …

A useful thing about the Vectric Aspire, is the ability to use tags. These are basically areas the path uncut. Thus, when the piece is completely cut off, still remain a small “tabs” uncut that make the entire piece does not come loose and get in the path of the cutter. When finished, simply with a Cuttex we can cut these tabs and have the totally finished piece.

In this picture you see the tool path, so walking with a tool Ø3mm the outside of the vectors have loaded.

When the path is finished, no more than generate the G code, and upload LinuxCNC, as I have said in previous posts. This would be the result of simulation performed by the Vectric Aspire:

I also have a video of how makes the cut. After finishing, I realized that this drill is not ideal for this type of work. Cutting it short, but leaves burrs, and it shows very forced. Also, I get the impression that gradually loses the cutting edge.
