make a machine, including the end effector
build the passive parts and operate it manually
document the group project and your individual contribution
Our group's machine is an auto egg-roll cutting tool. Everyone had no idea about how to make this machine. Then we stuied the lecture one more time and gather all the materials we need.
This is the first time I had real understanding of engineering: everything should be perfectly matched.
We started from measuring the components:
Then I read these tutorials:
- The Machines that Make Project at the MIT Center for Bits and Atoms
- We have another spot for documentation here.
In the beginning, I tried to use the cut files in the tutorials. But the cardboards in our lab weren't satisified our need. So I redesign the 3D model in Fusion 360.
First, set the parameters for components so that we can make quick change according to the material we use
then draw parts one by one
Laser Cut and Assembly
Since the woodboard in our lab is 450 mmx300 mm, we had to divide them into two parts and glue them together.
The cutting parameters:
I was not confident about my design, so I do some experiments:
It seemed ok:
then we made the real parts and assembled them:
Ready for the next week!
