Though we had many discussions around assignment, and as recommended by instructors, we selected CNC
plotter as our main machine to be designed We selected core xy as the main mechanism.
Talking about Core XY, First of all Thank you to Ilan E. Moyer for the great documentation from which we could learn a lot. Please refer to this documentation for the detail theory
Then we divided the team into five groups:
1. Mechanical Design
3. Electronics and programming
4. Material and management
I was assigned to in Design(helping Pallab with iterationing CAD),testing parts and fabrication.
We Went through various process from designing, fabricating, testing, assembly, and most importantly prototyping a lot of mini parts as per designs.
As a team we first discussed will all about how to make it. For the driving system, timing belts with stepper motor was confirmed.
For that we got out specification of our machine size wise
Machine size: 1110mm(x) * 1060mm(y) * 175mm(z)
Bed size: 766mm(x) * 756mm(y) (Updated after designing)
Please follow this link for the group website.
Testing inserts in 3d printed pat and dimensions.
fabricated and tested flex distance in flexure.
Tested inserts on laser cut flexures
3d printing gantry parts
Assembling the Parts.

Why Shape Optimization?
>>Saves lot of 3D printing material.
>>Faster 3D printing.
>>Cool looking ; )
After Shape Optimization.
