Automate your machine document the group project and your individual contribution.
Automate your machine document the group project and your individual contribution.
For this week, we, as a group, have to design a machine.
For that we took my final Project as an idea.
My final Project is to do a Jacquard machine.
For this assignment we would do a regular weaving machine.
The basic structure for the machine would be as this one on the image.
We would putt he thread cones at the begining, then the threads would go throw a guide and then they would be separeted between the first warp needles and the second ones.
Between both sets of warp needels, would go the weft needle.
Afther that, a comb will push the threats together and finally a roller would roll The fabric down.
The next image shows each part of the machine.
Alejandro did this diagrams to show how would it work.
The group, which is formed by:

and Me, with our mentor Isaac Robles, decided to change the machine we wanted to do, and instead, we are doing a “Cookie Machine”.
The idea is to make a machine where you can put the cookie mix on a tray which moves back and forward (first movement ) so the roller makes it flat and cut it in shapes, this roller needs to go up and down and back and forward.
We divided the work, Guillermo did the planning and model on AutoCad.
Alejandro modeled in Auto Cad Inventor and printed the roller on the Cube 3d Printer from the lab.
We use the Shopbot to make the HDPE fiber tray.

I took care of laser cutting and assembling the boxes and the engines. I downloaded the files from the ESAN LAB site. Which had a version of the originals that was fixed to fit on the laser cuter that we have, that has a size of 60x90 cm.
I needed two 60x90, 3mm paperboard for each engine box, from which I needed 5.
We couldn´t find the same exact kind of paperboard, and even with the same dimensions and thickness, the power and speed had to be changed after this Little incident:
With all the pieces cut, I orginezed them to start the assembly.
At the beginning it was hard to figure all the parts until I found a Gift on a documentation site that helped me(I´m trying to find the web again to link it, as soon as I do I´ll add the address)
Here are some screen shots of that GIF
With that, I began the work:
When I finished the boxes I went with Alejandro, who was working the programming part.
In the end, It worked, but we should use other kind of mix, drier and without chocolate chips because they get stuck on the roller.
