The anticipation had been building for months, and finally, the day arrived. Robby, Camille, and Ryan, members of the Hill Engineering team, embarked on a journey through time as they attended the Taylor Swift Eras Tour concert in Santa Clara, California.
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.Continue reading Overcoming Challenges in Residual Stress Measurements on Small Test Specimens Using the Slitting Method
