Week 2: Vinyl and Laser Cutting
Vinyl Cutting
Decided to make my Mom's name in Arabic Calligraphy
Laser Cutting
Since I have a good amount of prior knowledge on laser cutting I decided to focus this week on making a good parametric part for making living hinges in SolidWorks
Week 2
Vinyl Cutting
My Mom's name in Arabic Calligraphy
Used an online tool to make her name into a PNG.
Then I binarized the image for the vinyl cutter
Finally I cut it out
Laser Cutting
Living hinge parameterized design
My goal was to create a file I can change just a few parameters and get a working living hinge
After several hours of painstaking CADing, I was able to achieve my goal... Or at least the most basic requirements of it
This file lets you change just a few numbers and then spits out a living hinge. you can change the size of your hinge, the spacing between each hinge (varies stiffness), and few other small parameters like the chamfer for your finger joints, and material thickness.
Making Something with It
A Cup
After I made the hinge, I thought what would be the best way to test my design, and not break it?
After some though I came up with a Cup.
Base
Compared to the hinge making this in CAD was very simple
Cover
Finally to make it a cup it needs a cover and making that was super simple. I just took the base and put a hole through it
Group Assignment
Characterizing Our Laser
For our group assignment this week we had to characterize our laser and find the best settings for cutting carboard. We found that to cut cardboard we need a power of 75% and speed of 10%. After we figured out the settings to cut the cardboard we calculated the kerf to be ~1.14mm
