CNC Router Proposal
Ariel Swingley was selected for her dependability in projects, positive attitude and intense work ethic. She also attended MASEI over the summer and already has basic knowledge about robots and what all it takes to create them. She also has other positive capabilities such as being Google Sites savvy, which is important because that is the medium of our DP for engineering, this year.
Diana Barlow was selected because of her unwavering work ethic and positive attitude. She is a very dependable project partner because she will keep others on task and does not accept bad work or laziness. She also attended MASEI over the summer, which puts her ahead of the curve than most in robotics.
2.1 Team Description
2.1.2 Individual Biographies
Ariel Swingley was born on April 13th, 1992 in San Diego and has lived here her entire life. She is currently 17 and trying very hard to decide where she would really like to go to college. Ariel wants to be some kind of surgeon (leaning closer to Neurosurgery) when she gets older, despite the fact it will be about 20 years of college, medical school, residencies, etc.
Diana Barlow was born in San Diego on May 12, 1992. She has been going to High Tech since the 8th grade and is now currently enjoying her senior at High Tech High Media Arts. Diana likes crafts and projects she gets to work with her hands so engineering is a great opportunity for her. Diana wants to be an Obstetrician Gynecologist when she grows up, because she loves babies.
2.2 The Project
For our senior project we would like to build a CNC Router. A CNC Router is essentially a computer numerical controlled Router, meaning that we can program the computer to tell the CNC Router to cut or drill out any shape from a plank of wood. By building it, we would save our class time and money when building future projects. We also plan on entering our CNC Router into the Science Fair.
2.2.1 Essential Question
How can we build a fully operational CNC Router capable of cutting out any design we create on the computer by the end of the semester?
2.2.2 Primary Group Components
Both Ariel and Diana will be in charge of the design, programming and construction of the CNC Router. Structure assembly is something both Ariel and Diana have successfully done before with projects and will be less of a challenge than programming, which neither have previously attempted
Please Note: The X&Z gantry, Y rails and motion control systems will be built by MAE students and have been designed by: Patrick at http://buildyourcnc.com/default.aspx
The final table, wiring scheme, and cooling system will be designed and built by MAE.
Components added for roller chain system:

2.2.5 Specific Team Member Components
Diana Barlow will be focused specifically on the four axis that the router travels upon. These axis are necessity for the CNC Router to function and they have to be set up perfectly for it to work well. She would also like to focus her attention on securely connecting the CNC Router to the table.
By building the CNC Router the group hopes to solve the problem of human error when making exact pieces (such as the frame) for HTHMA’s AUV. We would reduce the time it takes build each experimental piece so the AUVSI team can focus on making the best robot as a whole.
The biggest limitations to achieve success will be the team’s slender knowledge of coding. Another limit would be designing our own version of the CNC Router to fit our own needs, such as the table size. We are also very limited with the amount of space we have inside the shop because we would be taking up a lot of room with our final product.
The group plans to measure the success of their project by whether or not they can build an efficient CNC Router that can cut and drill with precision. We would also at least enter into the Science Fair with our final product.
2.3.3 Specific Math and Engineering Connection
Ariel Swingly knows that the CNC Router will be a very complex machine to build, and will require considerable amounts of electrical engineering, geometry, algebra and trigonometry. Ariel and Diana will need to figure out exactly how exactly the machine should be put together for it to work, then using algebraic, trigonometric and geometric formulas and techniques, make the structure perfectly supported so that no stress is put upon the motors due to faulty alignment. The team will need to use electrical engineering techniques such as wiring and programming to make the CNC Router to fallow exact commands so it can cut things out perfectly.
Diana Barlow’s connection between math, engineering and the CNC Router relvolves around the use of electrical engineering techniques such as coding and wiring to complete the project. Every piece built must be perfectly measured to result in a presice and accurate project.
Ariel Swingley’s engineering subcomponent will be updating the DP on the team’s Google Site page with all the up to date robotic information as well as the step by step process and components. Making sure the DP is constantly organized and polished so anyone can look at it and fallow to exactly what step is currently being completed, is a huge standard of the DP that will be met.
Diana Barlow’s engineering subcomponent will be to digitally capture the process of designing, building and finalizing the CNC Router. That way there will be lots of evidence to show the amount of drafts, revisions, designs, and construction that went into our final product, as well as the challenges we encountered and triumphed.
We will be contributing to the AUVSI competition by building a machine that is able to build custom pieces specifically for our AUV. By having a machine build all the pieces instead of making them with tools we eliminate a lot of error accumulated by humans making them from scratch. This will also help majorly reduce the amount of time spent building pieces that may not work well, so scratching and trying another design will take half as much time.
On another note, by building our own CNC Router, our knowledge of coding, problem solving and designing will tremendously increase. We can then have more than just one coder working on all the sensors for the AUV as well as take on some of the CAD and SolidWorks 3D modeling, making the whole AUV completion process all around smoother.
