Overlapping Pursuits
More than any other field, IIoT overlaps directly with metrology's mission to analyze and measure as much of the manufacturing process as possible, and it's no surprise that the latter is utilizing the former.

Plastic Gear Design Remains a Work in Progress
Despite the development and availability of a number of newly engineered, rugged materials intended for plastic gear applications, some engineers/designers continue to believe metal is better.

In-Process, Complete Gear Inspection at Light Speeds
New GRSL technology adds value to high-volume transmission gear inspection by combining non-contact laser inspection with tried-and-true composite roll testing.

Facing the Future - Emerging Technologies in Heat Treating
The following article highlights some of the recent heat treat products, technologies and industry news articles for gear manufacturing.

Inspection System Upgrades Meet EV Gear Challenges
Delta Research upgrades its Gleason Metrology Workhorses to meet the development requirements of the latest electrical drive vehicles.

A Comparison of Current AGMA, ISO and API Gear Rating Methods
There are many different gear rating methods in use today, and they can give substantially different results for any given gearset. This paper will make it easy to understand the choices and the impact the choices have on gearbox design. Eight standards are included - AGMA 2001; AGMA 6011; AGMA 6013; ISO 6336; API 613; API 617; API 672; and API 677. (Click HERE for the Appendix to this article).

Complete Measurement of Gearbox Components
In today's production environment, a variety of different measurement devices is used to assess the quality and accuracy of workpieces. These devices include CMMs, gear checkers, form testers, roughness testers, and more. It requires a high machine investment and a high handling effort - especially if a full end-of-line measurement is needed. One approach to reduce quality costs is to include all measurements in one single machine that is suitable and robust enough for use in production.

Sensitivity Study of Press Quench Process and Concept of Tooling Design for Reduced Distortion by Modeling
Press quenching is designed to harden steel gears while minimizing distortion, and the process is especially applied for hardening large diameter thin-wall gears, face gears and bevel gears. The dimensional control aims at maintaining flatness, out-of-round, straightness and consistency of radial size. The press quench tooling and the process design have been mainly experience-based, using a trial and error approach for implementation of new processes, new gear materials and gear configurations.

Machine Tool Memories (Addendum)
A recent visit to the Henry Ford Museum of American Innovation, located in Dearborn, Michigan, helped remind this editor how different the manufacturing floor looked when the Ford Model-T was first being produced in the early 1900s.
