Open Source Mechanical Tester using CNC Machine

This slideshow is part of: Eric Lima

The goal of this project is to create an automated mechanical tester which takes advantage of the high level of precision of existing CNC machines. The team achieved this by designing a load cell attachment to fix on to the spindle on the CNC machine, as well as writing a program that leverages the machine's software driver. The result is a precise, automated, low-cost solution that equips researchers with the means to stress test their prototypes without expensive, dedicated machinery. 

The CAD models of the load cell attachment as well as the latest version of the control program are available on the project site.

  • Founded by inventor, industrialist and philanthropist Peter Cooper in 1859, The Cooper Union for the Advancement of Science and Art offers education in art, architecture and engineering, as well as courses in the humanities and social sciences.

  • “My feelings, my desires, my hopes, embrace humanity throughout the world,” Peter Cooper proclaimed in a speech in 1853. He looked forward to a time when, “knowledge shall cover the earth as waters cover the great deep.”

  • From its beginnings, Cooper Union was a unique institution, dedicated to founder Peter Cooper's proposition that education is the key not only to personal prosperity but to civic virtue and harmony.

  • Peter Cooper wanted his graduates to acquire the technical mastery and entrepreneurial skills, enrich their intellects and spark their creativity, and develop a sense of social justice that would translate into action.
