Broaching is a machining technique commonly used to cut gear teeth or cam profiles for the high volume manufacture of power transmission parts used in vehicles (Refs. 1–2). This article shows how the right gear blank material can make all the difference if you want to get more parts out of each tool.

While designing gear and spline teeth, the root fillet area and the corresponding maximum tensile stress are primary design considerations for the gear designer. Root fillet tensile stress may be calculated using macro-geometry values such as module, minor diameter, effective fillet radius, face width, etc.

It's hard to think of a show more essential to attend than IMTS. It's the cornerstone event for the industry, the center of the universe for a week, the one show to rule them all.

Most books related to the gear industry are more about the business side or the technical aspects of what we do.
