====== Modified CNC Mechanical Tester======

===== Problem Statement ===== 
{{  :start:classes:principlesofdesign:cncmechanicaltester:quick_pic.png|}}
Our goal is to increase the accuracy and efficiency of The Cooper Union's open source mechanical tester by integrating the system with a Roland CNC machine. This will result in:
  * Accurate position detection
  * The ability to test multiple samples in one session
  * A cheaper alternative to mechanical testers 

To learn more about this project, you may continue reading, or go directly to our website at http://students.cooper.edu/isakov/CNCMechTest/HomePage.html.

To meet the team and learn a little bit more about the project, you can watch this [[http://www.youtube.com/watch?v=aGXDWZBgvh0|video.]]

===== What will you find on the Website? =====
 **There you will find a comprehensive instruction manual for testing the mechanical properties of biomedical material within a Roland CNC Machine** 

  * __This includes:__
     * Instructions for making a physical connection between your load cell and your CNC machine
     * A guide to download Python 2.6, and the supplementary programs needed to run a mechanical test
     * A guide to download NIdaqtools for communication between the signal conditioner, DAQ board, and the Python program.
     * Programming that uses user's variables to create g-code, run mechanical tests, and save the data that is collected in an excel file. This will be done through one Python generated homepage, which calls upon various sub functions.

  * __You need:__ 
     * A Load Cell
     * A Roland CNC machine
     * A signal conditioner
     * NI DAQ board

===== Tutorial =====
The new program to run the CNC machine is now under the [[classes:principlesofdesign:cncmechanicaltester:Programming|programming page]]. The tutorial to learn how to run the program can be found on that page, or right {{:start:classes:principlesofdesign:cncmechanicaltester:the_mechanical_test_tutorial.doc|here}}. Other tutorials, including video tutorials may be found on our [[http://students.cooper.edu/isakov/CNCMechTest/HomePage.html|website]].

===== Looking Ahead =====
Ideas for the future:
  * Create a reproducible program that is easy to use
  * Automated sample tests (such as in a conveyer belt)
  * Automated load cell changes
  * Creating and maintaining a sterile environment
  * Testing samples from various angles and axes

===== DAQ Organizer Box =====

{{:start:classes:principlesofdesign:cncmechanicaltester:loadcellmount.zip|Here is the connection between the load cell and the CNC machine}}

  * A design table was created to simulate different radii and heights for the load cell mount.
