For over 30 years, AGMA has been hosting a technical conference to highlight the newest emerging technology in the gear industry. The Fall Technical Meeting (FTM) is the top place to learn about the latest research in the gear industry from the researchers directly. Each year, the FTM provides an outstanding opportunity to share ideas with others in the gear industry on design, analysis, manufacturing and application of gears, gear drives and related products, as well as associated processes and procedures. Attendees get a chance to be on the cutting edge of gear research and network with other engineers.
Each speaker will present the content of his or her technical paper that has gone through a double-blind peer review of three industry topic experts. All papers presented at FTM will be indexed in Scopus, the international database of peer-reviewed literature.
Come see why this popular event is growing year after year and be a part of a technical community that is always striving to improve and grow the gear industry.
*Abstracts and presentation titles are below. Please note that author information will not be disclosed until the full double-blind review process has ended.
AGMA has added an extra evening of networking and fun to the FTM! Sponsored by Scot Forge, FTM attendees that purchase a ticket for just $50.00, can attend an evening full of bowling, bocce and great conversation with their gear industry peers. Dinner and open bar is included with your ticket at the Pinstripes in Oak Brook. Please visit the Pinstripes website to get a look at what to expect! Visit Pinstripes
Session 1: Application, Design, and Rating
This session will tackle some complex projects including rack and pinion designs for offshore jack up, better spline design, external involute gears and techniques to improve gearbox designs for the food and beverage industry. Presenters discuss their mathematical models and their insights for improving process and standards for the increasing accuracy demands on these manufactured parts.
Session 2: Optimization and Performance
We have spent the last hundred years optimizing the design of a gear. More and more, we are seeing the focus shift from the component itself to the surface of the gear teeth and optimizing these surfaces for precision applications like transmissions, removal of noise for electric drives and more. Some presentations in this session will discuss surface and ideas for modifications along with gears operating in aerospace under the loss-of-lubrication conditions.
Session 3: Gear Wear and Failure
This session highlights one of the most important factors of our industry—when a gear will fail. Presenters look at this issue from a variety of settings to figure out not only ways to prolong the life of a gear but also to see how we can better predict and prepare for failure.
Session 4: Manufacturing, Inspection, and Quality Control
Computers have changed how we do many things in our lives and they continue to change the way we do things in manufacturing. Presenters in this session will look at applications and software tools, in development, that may help predict tool wear, provide more accurate simulations, fully automate inspection and measurement, and start to develop standards in some areas reflecting the use of these new technologies.
Session 5: Materials and Heat Treatment
Precision solutions—especially in automotive and aerospace endeavors—are forever driving our industry to discover new materials or new ways to achieve lighter, stronger, and more precise gear sets. This session outlines the latest innovative ideas in heat treatment and surface structures; and explores advances in clean steels and new materials.
