On the Road with the Residual Stress Field Team

by Robert Pires

In the ever-evolving landscape of materials science and engineering, on-site solutions are an important component of residual stress testing. That’s why we at Hill Engineering have a dedicated residual stress field team, capable of traveling directly to customers’ locations in order to deliver the same precision and data quality of our in-house residual stress measurements.

Senior Design 2023: An automated wire preparation device

by Camille Fowler

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.

Hill Engineering Joins CMTC’s Made in California Program: A New Chapter in Manufacturing Excellence

by Robert Pires

In an exciting development for both the aerospace industry and the state of California, Hill Engineering has officially been welcomed to the California Manufacturing Technology Consulting (CMTC) Made in California Program.

IMx+ system receives ATO from USAF

by Camille Fowler

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

by Camille Fowler

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.

Hunting for Meteors at Caswell Memorial State Park

by Camille Fowler

Nothing sums up summer quite like a good camping trip. A handful of Hill Engineering families made their way to the Stanislaus River and Caswell Memorial State Park for a weekend of nature, campfires, and s’mores.

AS7045 – Residual Stress Measurement and Classification, Metallic Structural Alloy Products and Finished Parts

by Camille Fowler

A new Aerospace Standard, AS7045 – Residual Stress Measurement and Classification, Metallic Structural Alloy Products and Finished Parts, was recently published by SAE International. Hill Engineering was actively involved in the development of the standard along with many of our collaborators in the aerospace industry. AS7045 offers tremendous potential to revolutionize the management of residual stress during metallic material procurement.

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

by Ryan Tucci

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.

Presentations at TMS 2023 Annual Meeting & Exhibition!

by Adrian DeWald

Hill Engineering recently co-authored presentations at the TMS 2023 Annual Meeting & Exhibition in San Diego, CA on March 19^th through the 23^rd. The TMS Annual Meeting & Exhibition brings together more than 4,000 engineers, scientists, business leaders, and other professionals in the minerals, metals, and materials fields for a comprehensive, cross-disciplinary exchange of technical knowledge. The abstracts for the presentations that we co-authored are copied below.

New Vlog: How To Apply A Strain Gage

by Robert Pires

Strain gages feature in a large portion of the residual stress measurements we perform at Hill Engineering, which is why we pride ourselves on our ability to correctly choose and apply strain gages to fit any measurement needs.
