For our second project, we got to do something a little more advanced and it also left a lot of room for creativity. We got to make signs using the CNC machine the only requirements .wre that it had to include text and have a visual element. I got to apply my old skills from our first project such as tools in Adobe Illustrator. I also got to use fusion 360 and learn many new skills including how to create 2D pockets and contours and the overall basics of fusion 360.

Since this project was pretty much open-ended. I did lots of research on what my sign could look like and I looked at many different sign designs online. I then thought about what my sign could say for the text requirement of the project. I decided on my name. For the visual requirement, I thought of what I was super passionate about and what I loved. I decided I wanted to have some visual aspect of softball in it. I then started sketching different ideas and possibilities for what this design could look like. This is the image I used for inspiration for my sign.
Once I started Adobe illustrator I uploaded a picture online that I used to trace out my design with the pen tool. I didn’t like the way it looked and wanted something more symmetrical and clean-looking so I deleted my design and restarted. I started by using the text tool and typing each letter of my name in a separate text so I could adjust each letter to fit. I then used the shape tool and made a circle. I then used the erase tool to erase part of my circle so it fit my name. I then used the pen tool and made my bat. I adjusted it to be as symmetrical as possible. I then adjusted the letters so they were connected to my bat and adjusted my circle to connect to the letters. I then used the pen tool to create laces on the circle so you could tell it was a softball. I then made my single lines into doubles line. I then used shape builder to get rid of lines and make my design one shape. I then saved this file as a DXF file so that I could open it on Fusion 360.
First, I opened Fusion 360 and started a new sketch. I then uploaded my DXF file onto fusion 360. I set the dimensions of my stock as x=12.5, Y=6.5, and Z=.5. I hit design to find the rectangle tool. I added my rectangle and hit command f to set the dimensions of my rectangle. I then embedded a rectangle around my shape. I then extruded by shape to .5 by hitting cut then body. I then opened the stock tab and for mode, I had from solid and for stock solid, I selected modeled stock material. I then opened the setup tab. For machine, I had none, for operation I had billing, and I selected WCS selection. I then selected the correct x and y-axis. I then set my stock box point so that it was located at the front, left, and top corner. I then opened the post process tab and for the program name/ number put 1001. I also commented my job name.
For the second part of fusion 360. I focused on 2D pockets/ contours and ran a simulation to really prepare for printing my sign on the CNC machine. First I went onto the Dawson portal and downloaded the tools such as the 1/8 inch bit and the quarter inch bit. I then selected my quarter inch bit by hitting select then download tool then tool quarter inch. I set the maximum roughing step down allowed to .125. I then selected the bottom surface of my pocket I selected. I then set my axial stock to 0. I then did the same with my 1/8 bit and selected the pockets I wanted it to go back and clean up with. I then ran my simulation to make sure everything looked right and it would print looking just how I wanted. Once I watched my simulation a few times checking for mistakes. I finally moved on to my post-processing. I checked to make sure I had the correct setup activated and that my file name matched my comment. I then made sure my post was set to centroid. I then emailed my file to the maker space email so I could print my sign from the laptop that is connected to the CNC machine.
I grabbed a piece of pre-cut plywood and taped it. I then taped where I was going to attach it to the table and made sure it was correctly lined up and straight. I then super glued it down. I then opened my emailed file on the CNC laptop. I set my x, y, and z right with the machine double checked it then ran it. It used the quarter-inch bit first then switched to the 1/8-inch bit to clean it up. I then took my sign-off. I then sanded my sign with the handheld sander to get rid of little pieces of wood sticking up. I then had my finished product.
What went well? I think my work on Adobe illustrator and fusion 360 went really well. I think I did a good job of taking my ideas on paper and making it in Adobe Illustrator and fusion 360. I thought I did a good job of problem-solving on these programs and putting my vision to life on the programs.
What could be improved? I think my overall result could be improved parts of the wood got chipped away and I wish I made it thicker so this wouldn’t have happened and I could have gotten a cleaner result.
What would you do differently if you were to do this project again? If I did this project again I would make my words and lines thicker. I also would try to do something more complex to challenge my design skills.
