While AGMA 909-A01 is a broad "specifications" document, AGMA 1003-A01 is narrowly focused on geometry. If you only need the actual tooth dimensions (addendum, dedendum, clearance, fillet radius) for plastic gears, 1003-A01 is the correct PDF.

Suppliers and manufacturers worldwide recognize the AGMA 20151-A01 methods. When you design to this standard, you can send your gear drawings to any competent manufacturer with confidence that they understand the rating formula.

Many engineering forums from the early 2000s posted links to PDFs that no longer exist. AGMA revises standards; the "A01" revision has been reaffirmed but may be superseded in certain sections by later addenda or combined standards (such as ANSI/AGMA 2105-A18 for aerospace).

If you need a summary of the accuracy class tables (e.g., tolerance values for runout, pitch, or profile for a given module range and class number), I can provide a representative example based on the standard's public references. Just let me know.

ANSI/AGMA 2015-1-A01 is a critical historical standard developed by the American Gear Manufacturers Association (AGMA)

that established an accuracy classification system for tangential measurements of cylindrical gears. While it was a groundbreaking document that unified North American and international gear standards, it is now considered and has been superseded by newer ISO-aligned standards. Overview of the Standard The standard, titled

"Accuracy Classification System - Tangential Measurements for Cylindrical Gears,"

was approved in August 2001 (reaffirmed in 2008) to provide gear manufacturers and buyers a mutual reference for uniform tolerances. Primary Scope:

It applies to spur and helical gears, correlating gear accuracy grades with specific tooth tolerances. Accuracy Grades: It defines 10 grades, numbered A2 through A11 Key Shift:

In a major departure from previous standards like AGMA 2000-A88, it reversed the numbering system. A smaller number (e.g., A2) represents a higher precision

gear, whereas a larger number (e.g., A11) indicates a lower precision. Accuracy Groupings

The standard categorizes gears into three main groups to determine the minimum measurement requirements: Required Measurements High Accuracy

Cumulative pitch, single pitch, lead, profile total, slope, and form. Medium Accuracy Cumulative pitch, single pitch, total profile, and lead. Low Accuracy Only cumulative pitch and single pitch are required. Historical Context & ISO Alignment

ANSI/AGMA 2015-1-A01 was designed to reconcile the differences between the old North American "Q" grades (AGMA 2000-A88) and the international ISO system. It combined the grading system of ISO 1328-1

with the evaluation methods familiar to the North American market. Notable changes introduced in this standard included: Agma 2015-1-A01 | PDF - Scribd
