The helix evaluation range—the part of the tooth flank where tolerances are applied—is different.
Many universities and large corporations maintain subscriptions to IHS Markit or Techstreet. If you work for such an organization, you can download the PDF internally at no additional cost.
This is the heart of the standard. As the gear rotates, a stylus tracks the variation in the path of the "rolling" curve. The standard breaks this down into two distinct components:
) : The displacement of an actual tooth profile from its theoretical position relative to the adjacent tooth. Total Cumulative Pitch Deviation ( Fpcap F sub p agma 20151a01 pdf

If you are working on a specific gearing project, please let me know:
By following these recommendations, users can ensure that their gears are designed and manufactured to operate safely and efficiently, reducing the risk of gear failure and downtime. The helix evaluation range—the part of the tooth
To save you time, avoid these pitfalls:
AGMA actively pursues copyright infringement lawsuits. Using an illegal PDF exposes your company to legal risk, and worse, the counterfeit PDF may contain errors (deliberate "watermark" errors inserted by AGMA to catch pirates). Your gear could fail catastrophically.
: Provides corporate licensing for engineering teams requiring multi-user access. This is the heart of the standard
: The structure of 2015-1-A01 was designed to align more closely with ISO international gear standards, facilitating global trade and manufacturing.

To be precise: is titled "Accuracy Classification System – Tangential Measurements for Cylindrical Gears." It establishes a standardized system for defining gear accuracy classes based on tangential (over-ball or between-pin) measurements, rather than radial or tooth-to-tooth composite methods.
