1. in today’s recitation, we are asked to make a turning wheel by laser cutting. we should be making the wheel using a specific website so that we can exercise the ability to make laser-cutting things.
2. first, I grouped up with Joy and divided the work, she was student A and I was student B. after a few minutes, we succeeded in making both of the boards, and she copy the website link of her work to me on weChat and I put our works together. I designed the still part of the turning wheel and Joy designed the moving wheel and we made their turning direction differently. then came the part of watching the laser cutting. we both come to 823 to learn things about laser cutting. and watched our wheels being cut. however, one of the wheels which is the still one should have a hole in it. but instead, the whole was not being cut. after consulting with professor Rudi, we know how to design it. we need to first make a bigger rectangle and then put the rectangle we need inside it and made the whole. after some time, we manage to cut out the piece we need. and the part of putting them together is rather simple. and after installing the program on Arduino, we successfully made the wheel spring.
3. the process generally goes as planned except for the part where the hole was not cut through. what we have learned is how to draw things using the website. also, we know how to make a perfect hole in our works without making it fall apart. in addition, we learn that in order to make our shape after rotation beautiful, we should make the original shape strange. what we also learned is how to make the two shapes into one website.
