Behold, the amazing idea of machine that the FabLab Puebla will develop:
The CNC tufting machine!
Tired of your plain carpets? Do you want to add some groove to them?
Then The CNC tuftung machine is specifically design for you.
This is a hand tufting gun:
And this is hand tufting:
This is a demostration video of hand tufting
We wanted to do this machine as a challenge, we think that it wasn't really complex and that can be done to obtain great results in different fabrics.
For our machine we are going to use movement in three different axis. For the X and y axis movement we are going to use belts. For the z movement we are going to use an worm gear.
The decision was made in the weight, the dificulty of assembling together and the Speedy of the movement needed in each axis. The X and y axis are Light, we need a medium Speed movement. So we chose the belts. The Z axis have more weight to hold. The machine won’t need mucho f a movement in the Z axis so we decided to use a worm screw.
Example of the power belt that we are going to use for the x and y movement
Example of the worm gear that we are going to use for the movement in the z axis.
For the up and down action that the needle has to have we are going a 3D printed Cam, this will let us control the speed and the rhythm of the needle action
Our work zone will hold this measurements:
The measurements for the mechanisms in each axis are as listed:
• The Z axis will use a worm gear measuring 150mm long.
• The X axis will use a Belt and will measure 300 mm long.
• The Y axis will use a Belt and measure 450 mm long.
The worm gear we are going to use is a single threaded. The pass is 1mm, so the advance is also 1mm because is single threaded.
The advance measurements for the X and y axis Belt will be the same.
We found an old structure gathering dust here in pur FAB and we decided to tune it and adjust it to work our purpose.
This was a 3D model of the machine we found. Obviously the physical structure that was made it didn't look quite like this.
The image above is the structure we found. It needed a lot of adjustments but the mechanical design was very much alike the one we needed.
Here I am starting the adjustments.
Here we can see how the structure looked at the end.
In the video above we can see the movement of the X and Y axis of our machine.
