Aerospace manufacturers turn to non-hazardous PVD coatings as regulations tighten on toxic hard chrome plating
March 6, 2019
The search for a suitable replacement to hard chrome plating on aerospace components has been a key supply chain priority for aircraft manufacturers. This is because of the documented health risks to workers and the impact on the environment from exposure to hexavalent chromium, a carcinogen that occurs during the chrome plating process and the most toxic form of chromium.
Norsk and SAE International collaborate on world’s first directed energy deposition specification
February 15, 2019
Norsk Titanium’s proprietary “Rapid Plasma Deposition” (RPD) additive manufacturing (AM) process is distinguished in the aviation industry for producing complex, titanium structural and safety-critical components for many original equipment manufacturers (OEMs). But today, through a partnership with SAE International, Norsk’s RPD process and material requirement specifications are available to a wider, global base of manufacturers.
Thermwood and Bell 3D print the largest autoclave capable tool yet
February 11, 2019
Dale, Indiana-based Thermwood Corporation – a manufacturer of computer numeric control (CNC) routers and large-scale additive machines (LSAM) claims to have produced the largest autoclave capable tool made through additive manufacturing (AM), commonly referred to as 3D printing. The tool – one half of an 18-foot helicopter blade mold – was built up in just over three hours as part of a joint venture program between Thermwood and Bell Helicopter of Fort Worth, Texas.

Wire Fed Plasma Arc Directed Energy Deposition Additive Manufacturing Process
Standard
AMS7005
This specification establishes process controls for the repeatable production of preforms by Wire Fed Plasma Arc Directed Energy Deposition (PA-DED). It is intended to be used for aerospace parts manufactured using Additive Manufacturing (AM) metal alloys, but usage is not limited to such applications.

Shearographic Nondestructive Testing for High-Pressure Composite Tubes
Technical Paper
2018-01-1219
In response to the need for lightweight design in industries, composite materials are increasingly used to replace traditional metal tubes. However, subsurface defects such as voids, delaminations, and microcracks are still remaining common issues in composite pressure tubes.
Lightweight Carbon Composite Chassis for Engine Start Lithium Batteries
Journal Article

The supersession of metallic alloys with lightweight, high-strength composites is popular in the aircraft industry. However, aviation electronic enclosures for large format batteries and high power conversion electronics are still primarily made of aluminum alloys.
TruPLAN Advanced Simulation for Material Kinematics Behavior during Manufacturing Layup Processes
Journal Article
2012-01-1856
The objective of an engineering analysis - a numerical model and simulation designed to represent a specific manufacturing process - is not simply to determine the behavior and impact of that process on a specific product. If that were the case, extensive product testing would be a simpler and cheaper solution.
Friction Coefficient Evaluation on Aluminum Alloy Sheet Metal Using Digital Image Correlation
Technical Paper
2018-01-1223
The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes. This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3D digital image correlation (3D-DIC) to track the deformation.
