Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, specialized in the industrial robotics, 3D modeler and designer.
I have over 15 years work experience, designing, prototyping and launching different devices/systems across multiple industries.
I could help with your project.
1 - what you shown in the video, is not a bending tool but a thermo-forming machine
2 - alongside with the machine as it is, you will also need different "heads" which to correspond to the base lens number, the IPD, and the shape of the glasses rims.
3 - in order to properly design this machine, we will need to determine the type of machine (power source, driving type, capacity, etc)
For any other questions, you may open a chat room here and we'll discuss about the details.
Regards
Bogdan
