First cut a small test part on scrap material before cutting your final assignment. ### Assignment: Work with a partner or group of 3. Optionally, you may work alone, but you'll be responsible for both parts of the assignment. <br> 1. Design something and make it using CNC. You may use the ShopBot (2D outlines), the <a href='https://www.shapertools.com/en-us/'>Shaper</a> (2D outlines) or the SRM-20 (2.5D molds). <br> 2. Post-process your design using fabrication processes such as <a href='../../lab/casting/casting.html' target="_self"> molding and casting</a>, <a href='../../lab/vacuum/vacuum.html' target="_self"> vacuum forming</a>, or <a href='https://roberthart56.github.io/SCFAB/SC_lab/Projects/composites_S19/index.html'>composites</a>. <b>Examples:</b> [Clarissa](https://c2bstewart.github.io/PS70/08_cnc/index.html) <br> [Mohammad](https://mohammed-mutaher.github.io/PHYSCI-70/08/index8.html) <br> [Felicia](https://fellyliang.github.io/PS70/08_index.html) <br> [Chase](https://ctv-harvard.github.io/PS70/assignments/week8/w8.html) <br> [Rebecca](https://rebeccabrand.github.io/ps-70-fall-22/week-8.html) <br> <h3> Reading: </h3> <a href='https://makezine.com/2014/03/21/cnc-routing-basics-toolpaths-and-feeds-n-speeds/'>CNC Routing Basics: Toolpaths and Feeds & Speeds</a><br> Read Chapters 2 and 4 of <a href='https://pdfs.semanticscholar.org/07b7/b7a82f9a49c0e9ad025a1c054494cd8362ec.pdf?_ga=2.150707894.1453144846.1581345886-1853978704.1565046663' > Making Things Move </a><br> <a href='https://formlabs.com/blog/low-volume-production-injection-molding-casting-thermoforming/'> FormLabs guide to molding and casting</a> <a href='https://learn.sparkfun.com/tutorials/serial-communication/all'> Sparkfun page on Serial/UART </a><br> <a href='https://learn.sparkfun.com/tutorials/serial-peripheral-interface-spi'> Sparkfun page on Serial Peripheral Interface </a><br> <a href='https://learn.sparkfun.com/tutorials/i2c'> Sparkfun page on I2C </a><br> <h3> Resources: </h3> <a href='../07_cnc/Shopbot_Aspire.pdf'>Aspire and Shopbot CNC demo</a> <br> <a href='https://www.youtube.com/nyccnc'>NYC CNC YouTube Page</a> <br> <a href='https://softroboticstoolkit.com/' >The Soft Robotics Toolkit </a> <br>
