Senior Design 2023: An automated wire preparation device

Over the years, Hill Engineering has had the opportunity to work with mechanical engineering undergraduate students at University of California, Davis, as part of their senior design capstone. The capstone pairs a group of students with a sponsor company in the industry to address a design challenge presented by the sponsor. For the 2022-23 school year, Hill Engineering submitted a project to the Mechanical and Aerospace Engineering department for an automated wire preparation device. This device would mainly be used by our engineers to cut “jumper wires” for a strain gage assembly, which are used for the many residual stress measurements we perform.

Overcoming Challenges in Residual Stress Measurements on Small Test Specimens Using the Slitting Method

When it comes to measuring residual stress in small test specimens, precision is paramount. The slitting method is well suited to this application due to the high accuracy of wire EDM machining. However, this method is not without its challenges, especially when applied to very small test specimens, such as the 0.022-inch diameter wire we recently measured.
