ABSTRACT Today’s combat vehicle designs are largely constrained by traditional manufacturing processes, such as machining, welding, casting, and forging. Recent advancements in 3D-Printing technology offer tremendous potential to provide economical, optimized components by eliminating fundamental process limitations. The ability to re-design suitable components for 3D-printing has potential to significantly reduce cost, weight, and lead-time in a variety of Defense & Aerospace applications. 3D-printing will not completely replace traditional processes, but instead represents a new tool in our toolbox - from both a design and a manufacturing standpoint.

New Generation of Forging Steels for Cyclic Loaded Safety Components with Improved Fatigue Properties2014-28-00054/28/2014
Lightweight design in the automotive industry is not always combined with the usage of alternative materials like composites. Even high strength steels have high potential for reducing the weight for lightweight design. For the forging industry a new steel is developed, which enables the TRIP-effect (Transformation Induced Plasticity) for forging parts. This material effect is already well known and used for steel sheet structures. The TRIP-effect is based on the structure of the TRIP-material containing retained austenite, which has the possibility to form residual stresses due to the austenite-martensite transformation under cyclic loading. Beside static properties, the dynamic and cyclic material behaviour has a high importance for parts in the automotive industry. So, for lightweight design, a focus has to be on fatigue behaviour under service loads including overloads for an optimal weight reduction. The traditional forging steels are the precipitation hardening ferritic-pearlitic steels (PHFP steel) and the martensitic quenched and tempered (Q&T) steels. In comparison to these steels, the new generation of TRIP forging steels has an improved cyclic material behaviour. To utilize this potential, attention has to be paid to the sequence of cooling down the material from the forging temperature because the properties of the material depend on the cooling rate between 500°C and 200°C. In this paper, the high potential of this new generation of forging steels is shown. First fatigue tests on TRIP-materials demonstrate the good results under service loads, especially under overloads and misusage loads.

Optimization in Forging Process Using Computer Simulation2014-28-00414/28/2014
New process development of forging component require lot of process knowledge and experience. Even lots of trial-and-error methods need to be used to arrive at optimum process and initial billet dimensions. But with help of reliable computer simulation tools, now it is possible to optimize the complete process and billet dimensions without a single forging trial. This saves lot of time, energy and money. Additionally, simulation gives much more insight about the process and possible forging defects. In this paper, a complete forging process was needed to be designed for a complex component. With the help of computer simulation, the complete conventional forging process and modified forging process were simulated and optimized. Forging defects were removed during optimization of the process. Also billet weight optimization was carried out. Deciding the pre-forming shape of the billet was the main challenge. With use of computer simulation, an innovative pre-forming shape was arrived resulting in reducing billet input weight. The entire forging process and billet pre-form was optimized in such a way that complete filling of cavity was achieved with minimum pre-form input weight without forging defects. Final component weight (net weight) to input pre-form weight (cut weight) ratio (i.e. yield) obtained was 81%. Further, the location of pre-form in the die was optimized and best one was selected which gave minimum wastage of material in flash.

This SAE Aerospace Recommended Practice (ARP) lists wrenching surface sizes and tolerances for fluid fittings which utilize machined or unmachined hex bar dimensions and machined or forged wrenching surfaces across the center body section of shape fittings.
G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled, cast, forged, flame cut, and machined cutting edge sections. Straight cutting edges are defined as those whose leading edge and rear edge are parallel and, thus, are of constant cross section. For "straight cutting edge sections with bolt holes," see SAE J1304 FEB85. NOTE—For some heavy duty applications, cross sections with larger blunts and greater bevel angles may be required.
