Build the design of the workpiece. Especially if you are not so good with 3d tools, it makes total sense to develop the template in a vector program. I use adobe illustrator for this. It's important to make sure that the shapes are clean, so that they can be further processed. Export it as SVG file format.
You import the previously created SVG file into a CAD tool. I use Fusion 360 for this. Create the 3d body of the workpiece. then create the router settings for the routing process. this is purely a matter of practice and you have to try it a few times until you hit the right settings. The last thing you do is create the machine code that needs to be imported to the CNC control software. More in part 3 of this guide.
To tell the cnc router what to do, code must be generated from the 3d tool. You then import the code into the control software for the router.
The CNC router is a precision tool. To be able to work accurately, the workpiece must be firmly fixed. I use a sacrifice plate, which I clamp onto the router and then screw the workpiece onto it.
Next, start the control software. I use Stepcraft UCCNC for this. Import the machine code you have created. If you have done everything correctly, the workpiece appears with the calculated milling paths. Now you have to set the 0 point to tell the CNC router where the center of the workpiece is and from which height the milling process should start. Everything else is done by the software when reading the machine code.
Now you can start the machine. If you have set everything correctly and selected the right drill bit, you will soon be able to admire the result.
To prevent the workpiece from slipping, i added small holders. i now cut these with the saw and sand the edges and surfaces.
After the surface treatment you can glue the parts. Use clamps so that the joints harden under pressure. After the drying phase you can proceed with painting the workpiece.
The last step is to paint the surface. I opted for a transparent oil. This brings out the wood structure well.
Here it is. A desk stand for my display. It fits nicely to my table top made of cork. If you'd like to have a look to the full guide, visit the guides section in my profile of the orojects on bude.tv. I hope you like it! Have a hood day y'all!
