METAL’s Manufacturing Workforce Network

A DoW-funded partnership brings online courses and hands-on bootcamps to Purdue’s foundry lab, training that feeds gear production

Many students and job seekers are unfamiliar with the advanced technologies and career opportunities available in metal casting and forging. But thanks to the Metallurgical Engineering Trades Apprenticeship and Learning (METAL) program, led by the IACMI-The Composites Institute, that is changing. METAL is partnering with universities to showcase the rewarding careers these industries offer. Together, these institutions are hoping to revitalize American manufacturing by delivering responsive, scalable, and sustainable workforce development programs.

Design Principles of Bevel Gears: Rationale for Zero Sum Profile Shifts and Generating Gear Choices

This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.

Conjugate Bevel and Hypoid Gears

An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld exploring the mathematics behind conjugate bevel and hypoid gears—from the fundamental laws of gearing and the conditions for perfect conjugacy to why real-world power transmissions require deliberate crowning rather than theoretically exact conjugate designs.

Analytical Calculation of the Gear Body Stiffness of Face Gears

This paper presents a new analytical method using plate and disk mechanical models to calculate the gear body stiffness of face gear wheels, showing that stiffness decreases toward the outer radius—a behavior that conventional cylindrical gear approaches fail to capture.

Water Spray Quenching—A New Intensive Quenching Process for Case Hardening of Gears

Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.

Design

The toothed belt and pulley system known by the designation T, which has been selected as an example within this paper, was developed in the 1950s and standardized first in DIN 7721 (1977) and then in ISO 17396:2014. In this case study, the authors check if a single hob can properly cut T5 profile pulleys with 25 and 30 teeth—and if
so, define the range of the number of teeth covered by this hob.

Grinding

From the outside, Gallmar Industries, nestled into an Oshkosh, WI, neighborhood, looks like any unassuming, medium-sized gear shop. Then take a plant tour with Gallmar’s VP of Operations Kenan Zolota—and prepare to be amazed. The facility stretches on like the Army’s warehouse at the end of Raiders of the Lost Ark, with everything from gear cutting to heat treat, gear grinding to inspection, all under one roof. Gallmar’s breadth of product line is in evidence too: defense-related transmission gears, 60-in. diameter internal gears for mining equipment, axle components for fire/ rescue trucks five feet in length, right down to a bin of brass ammunition casings that Zolota says are a special order.

Inspection

Zahnradfertigung OTT GmbH & Co. KG was the first company to install the new fully automatic CNC-controlled P 152 precision measuring center from Klingelnberg in its ultra-modern machine park.

Heat Treating

Heat Treat 2023 is the Heat Treating Society’s 32nd conference and expo for heat treating professionals featuring three days of face-to-face networking opportunities with approximately 200 heat treat exhibitors/companies. All the top heat-treating companies will offer the latest research and industry insights during more than 100 technical programs. This year’s show includes a VIP-guided industry tour, as well as student/emerging professionals initiatives, including free college student registration, Fluxtrol Student Research Competition, and the ASM Heat Treating Society Strong Bar Student Competition. Heat Treat 2023 is colocated with Motion + Power Technology Expo 2023 with access to additional exhibitors. The event takes place October 17–19, 2023 at Huntington Place in Detroit.
