IMx+ system receives ATO from USAF

You might recall a previous post introducing the Integrated Maintenance System, or IMx+ system, that uses next generation technologies to address the quality assurance needs of the aerospace industry. We’re happy to announce that the IMx+ system is now authorized to operate and connect to the USAF NIPRNET, a huge milestone for Hill Engineering and all groups involved.

Inside Hill Engineering’s Quality Control Program

In a previous post, we highlighted the steps we took to develop a Quality System that is compliant with ISO. Since then, we have successfully completed three renewal audits and are currently accredited to ISO/IEC 17025:2017, the most recent revision of the standard. Part of our Quality System requirements includes the creation and maintenance of a quality control program for the various residual stress measurement techniques we perform in our laboratory. Consistently providing high quality results to our customers is something we pride ourselves in and the best way for us to assure that is through a quality control program.

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.
