The article proposes a method to optimize cylindrical gearbox tolerances by balancing gear noise performance and manufacturing costs using modeling, analysis, and meta-model-based optimization.
This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.
When you talk with Jared Lyford, director of operations at Forest City Gear and the newly appointed president of the Rock River Valley Tooling & Machining Association (RRVTMA), it becomes clear very quickly: workforce development isn’t a program for him. It’s a calling—and one shaped by lived experience.
The disparities between workforce development in Europe and the United States are pronounced. For instance, apprenticeship programs in Europe commence at a significantly younger age and present a wider array of opportunities. While North American initiatives emphasize extensive cross-training in mechanical and electrical disciplines, the European approach delineates specific departmental and positional pathways much earlier in employees' careers. The challenge of training workers swiftly and effectively has long been a concern for manufacturing firms.
Operating for long hours, under extreme loads, in high temperatures and dusty environments, ongoing wear is a significant challenge for open gears. This can lead to unplanned downtime and reduced equipment life—creating a barrier to effective operations. Leading mining and cement companies use advanced grease technology and technical inspections to help prevent open gear failure, optimize service life and ensure the smooth running of their operations.

Schunk now provides an innovative clamping concept for these demanding requirements with the new ROTA THW3 2+2 power lathe chuck. This 4-jaw lathe chuck features two independent jaw pairs with subsequent centrally compensating workpiece clamping, enabling safe and reliable clamping of freeform parts, castings, or geometrically undefined workpieces.
Visual Components announced its Omni Experience add-on virtual application with NVIDIA at the NVIDIA GTC global conference in Washington, D.C. Scheduled for release in early 2026, the integration enhances the Visual Components simulation platform with a new viewport built on NVIDIA Omniverse’s application programming interface (API).
Walter has expanded its product range with the addition of the new thread milling grade, Tiger∙tec Gold WSM37G. The grade features the only PVD aluminum oxide (Al2O3) coating technology of its kind in the world, which provides an elevated level of temperature resistance and long tool life.
This installation marks the second all-metal hot zone vacuum furnace added to the climate-controlled processing area at Solar Atmospheres’ Hermitage, PA facility. The new system significantly expands the company’s capacity to heat treat highly sensitive materials such as precipitation-hardened stainless steels, nickel-chrome-based superalloys, titanium, and niobium.
Weiler Abrasives has expanded its color-coded product lineup to include some of its most popular brushes for stainless steel. The color-coding helps stop cross-contamination in operations working with both carbon and stainless steel by making it easy to identify the correct wire brush—even during operation. This helps operators get the job done faster, safer and better.
