It’s time to meet another Hill Engineering pet! Last time, we got to learn about Rho, the big pup who thinks he’s in a small body. Next up we have Tommy, the 4-year old Shiba Inu that can be described as sneaky and stubborn but most of all, smart.
Aluminum alloy heat treatment is a three-step process designed to achieve the desired properties. The process involves: 1) solution heat treatment (SHT) at an elevated temperature below the melting point, 2) quenching in a tank of fluid (e.g., 140-180°F water), and 3) age hardening. While providing good properties, the heat treatment has the negative side effect of creating bulk residual stress and distortion.
The world has changed drastically in the past few months. With cases of the Novel Coronavirus on the rise in California and in the United States, Hill Engineering is doing its part to ensure the safety of our employees and our customers.
Today marks a major milestone in the field of residual stress measurement. The contour method, one of the most useful and advanced residual stress measurement techniques, was first successfully implemented on this date (August 16th) in 1999 by Mike Prime at Los Alamos National Laboratory. The most significant feature of the contour method is its ability to generate detailed two-dimensional residual stress maps like the one shown below. Please join us in wishing the contour method a very happy 20th birthday! Continue reading Happy 20th birthday to the contour method
Hill Engineering’s machining process simulation service reduces uncertainty in machining planning and improves machining processes. By providing results from validated models, our services support the decision-making of contract machining vendors who want to efficiently produce high-quality parts and OEMs who want to maximize the productivity of their supply chain.

Distortion of parts during the machining process is a significant problem faced by many machining vendors. This phenomenon typically results from the release and redistribution of residual stress in the material once the part is unclamped from the machine table. When not accounted for, machining distortion can lead to out-of-tolerance parts that either require reworking, or have to be scrapped. Continue reading Case Study: Multi-step machining distortion modeling
Summertime is just around the corner and we at Hill Engineering are always looking to engage our followers with fun and interesting information about engineering and residual stress. This summer we’re going to host the virtual Hill Engineering STEM challenge – a series of fun activities to demonstrate your engineering intuition and creativity. Participate on your own or with your family to compete for some cool Hill Engineering prizes! Continue reading #HillEngSTEM Summer Challenge
