Lean Manufacturing
LEAN stands for a method of production management inspired by Toyota, focusing on customer care and waste elimination. Waste is any action that uses resources without benefiting the customer. Lean applies to management, organization, and production, even at home. Key principles include defining customer value, mapping the value stream, ensuring smooth material flow, creating a pull system, and continuously seeking perfection. Lean promotes a mindset of continuous improvement, beginning with standardization. This involves creating a standard and ensuring conditions meet that standard. Standards should be clear, reasonable, safe, improve quality, reduce costs, simplify processes, and allow for team feedback. Lean connects with ISO9000, which ensures consistency and promotes documentation, self-auditing, and continuous improvement. The Lean culture emphasizes respect for people, continuous improvement, leadership support in problem-solving, and improving processes rather than blaming individuals for mistakes.
The lean challenge we were given was to look at the way airplanes board and to lean it out. The way I approached it was by using some of leans guidelines. Lean has several guidelines, including value stream mapping, 5S, total productive maintenance, SMED, poka-yoke, kaizen, Jidoka, and just-in-time. These are meant to assist in implementing lean practices. The way these helped me with the challenge was I looked at the original method through the different lenses of these and it helped me come up with an improvement.
CNC Lathe
For the CNC Lathe we had to CAD/CAM and machining a part out. For my part I decided I wanted to make something practical, that thought led me to my decision to make a center punch. Center punches are used to create indents in the center of metals to indicate where to drill.
The first part of my process was to sketch my design in Fusion 360, creating different circles and boxes. I revolved them to make the center punch and the holder. I started CAMing with OP 1. 1, facing the part for a smooth surface. OP 1. 2 was roughing, OP 1. 3 was a finishing pass, OP 1. 4 was pocket cut, OP 1. 5 was thread cut, and OP 1. 6 was part off. For the holder, the operations were similar, but it had a drill hole instead of a thread.
After proving my G-code, I tested my part at Clover Park. I did a dry run and simulation, noticing some offsets were off. After adjustments, I machined my first point, but the pockets weren't cut, so I fixed that in Fusion. I ran the program again, and it came out perfectly.
Robotics
We learned how robots function, how to operate them, and the various types of robots. The main type discussed was Co-bots, which collaborate with people. We also covered industrial robots that operate in factories or warehouses, moving items in and out of CNC machines to maintain fast productivity.
Final cat drawing
The robot we worked with at Clover Park was a Co-bot. We programmed it to draw a picture and then designed a fixture to hold the grippers on the robot. I chose to pick up the point of my center punch, but my first scoop I designed in Fusion did not work out. After this error I switched to a different design, I thought it'd be better to measure the diameter of the part and make the grippers a little bigger than that so it'll still fit snugly since the 3D printers print them a little undersized. Once we got back to clover park the next week I printed them out and tested them, they picked the part up perfectly and fit just as expected on the gripper.
