ABSTRACT This paper focuses on the application of a novel Additive Molding™ process in the design optimization of a combat vehicle driver’s seat structure. Additive Molding™ is a novel manufacturing process that combines three-dimensional design flexibility of additive manufacturing with a high-volume production rate compression molding process. By combining the lightweighting benefits of topology optimization with the high strength and stiffness of tailored continuous carbon fiber reinforcements, the result is an optimized structure that is lighter than both topology-optimized metal additive manufacturing and traditional composites manufacturing. In this work, a combat vehicle driver’s seatback structure was optimized to evaluate the weight savings when converting the design from a baseline aluminum seat structure to a carbon fiber / polycarbonate structure. The design was optimized to account for mobility loads and a 95-percentile male soldier, and the result was a reduction in

Abstract Converting vehicles from conventional manned operations to unmanned supervised operations has been slow to adoption in many industries due to cost, complexity (requiring more highly skilled personnel) and perceived lower productivity. Indeed, hazardous operations (military, nuclear cleanup, etc.) have seen the most significant implementations of robotics based solely on personnel safety. Starting in 2005, the U.S. Army Corps of Engineers (USACE) has assumed a leading role in promoting the use of robotics in unexploded ordnance (UXO) range remediation. Although personnel safety is the primary component of the USACE mission, increasing productivity while reducing overall cost is an extremely important driver behind their program. To achieve this goal demands that robotic range clearance equipment be affordable, easy to install on rental equipment, durable and reliable (to minimize down-time), low or no maintenance, and easy to learn / operate by the same individuals who would
High productivity, low manufacturing costs, and high workpiece quality: these are the key factors that deliver sustainability, profitability, and competitive edge for industrial manufacturers.

Aerospace manufacturers know what it means to work with high stakes. Extremely tight tolerances, expensive materials and complicated processes define the industry. But few aerospace components are more critical - or more challenging - than the turbine discs that go into the hot side of jet engines. When machining these rotating components, everything must be correct, secure and reliable - not only to meet stringent surface integrity requirements, but also to avoid devastatingly expensive failures. A mistake that leads to a scrapped component can cost a manufacturer upward of $100,000, depending on when the mistake happened in the production process
In the 1st generation Toyota "MIRAI" fuel cell stack, carbon protective surface coating is deposited after individual Ti bipolar plate being press-formed into the desired shape. Such a process has relatively low production speed, not ideal for large scale manufacturing. A new coating concept, consisting of a nanostructured composite layer of titanium oxide and carbon particles, was devised to enable the incorporation of both the surface treatment and the press processes into the roll-to-roll production line. The initial coating showed higher than expected contact resistance, of which the root cause was identified as nitrogen contamination during the annealing step that inhibited the formation of the composite film structure. Upon the implementation of a vacuum furnace chamber as the countermeasure, the issue was resolved, and the improved coating could meet all the requirements of productivity, conductivity, and durability for use in the newer generation of fuel cell stacks

It's no longer a question of when metal additive manufacturing (AM)-and particularly metal laser powder-bed fusion (LPBF)-will become an accepted, reliable production technology, particularly in aerospace and defense. This is already the case now. Over the past 18 months a host of aerospace leaders, OEMs, startups, and contract manufacturers (CMs) alike have purchased, or begun outsourcing work to, advanced AM systems. They're confidently producing end-use, 3D-printed parts-and sometimes entire rocket engines. In a quarterly study of revenue growth of leading AM system-makers, published in the summer of 2022, the industrial sector was reported to have grown 19 percent compared to the same period in 2021. This was cited as proof that companies and users are looking to invest in the larger, more powerful industrial AM solutions that offer greater efficiency and productivity
Stainless Steel 304 (SS304) is a nickel–chromium–based alloy that is regularly used in valves, refrigeration components, evaporators, and cryogenic containers due to its greater corrosion resistance, high ductility, and non-magnetic properties, as well as good weldability and formability. Multiple regression analysis was used to establish empirical relationships between process variables. Additionally, the established regression equations are employed to predict and compare experimental data. Due to the increasing demands for high-quality surface finishes and complex geometries, traditional methods are being replaced by non-conventional techniques such as wire EDM. This process, which emerged from the electrical discharge machining concept, mainly involves creating intricate components. WEDM results in a high degree of precision and excellent surface quality. Due to the complexity of WEDM, the processing parameters cannot be selected by using the trial-and-error method. The various

Operational Technology (OT) networks are historically “air-gapped” from the rest of the networked world. But pressure is mounting for manufacturers to leverage real-time data exchanges from outside their controlled environments to increase productivity and efficiency. One major concern for manufacturers is how safe and secure it is to open the OT network’s doors to the internet
Threaded, potted inserts are commonly used as a standard connecting element for sandwich components, which are used for aircraft interior. Since they often offer the only detachable connection, they are used in very high quantities. To ensure a material bond between the inserts and the honeycomb structure, the joint is filled with adhesive. Despite the high number of inserts, this process is performed manually. Recent research has shown new approaches for automated gripping and placement of the inserts by an industrial robot that yield high potential for cost savings and increased productivity. Automated adhesive insertion, so-called potting, has not been considered so far but is an essential contribution to the full automation of the entire process chain. The amount of adhesive varies depending on the type of insert and its position on the honeycomb structure. During the potting process, it is also mandatory to prevent air inclusions, to fulfill safety requirements in the aviation
