Understanding Results on Report

[[Da...]]

Quick questions on the following acronyms on the attached file called “Gear Report Clarification.png”.  I did look in the help file as well in the presentation you sent us but still can’t find the answer.

 

• Est
• St
• Wk
• Eet
• et
• FrD

[[Ri...]]

et is the gap width; Eet is the gap width variance.

st is the tooth thickness; Est is the tooth thickness variance.

Wk is the span width; in this example it shows a k value of 2, so a span measurement over (2) teeth. 

MrK is the Measurement Over One Ball

MdK is the Measurement Over Two Balls

MdR is the Measurement Over Two Pins

Da is the Major Diameter

FrD is the Runout of the Major Diameter

Df is the Minor Diameter

FrD is the RUnout of the Minor Diameter

Richard beat me to it.  That's the exact infographic I train my lab techs on.  I've gotten more positive feedback by sharing this infographic with associates while discussing gears than any other infographic on any other topic.  

Zeiss really nailed it with this one.  Way better than the AI slop Calypso GDT package training videos they just released.

Slightly off-topic, but I'm so glad that the Gear world invented and embraced gear nomenclature because some of the descriptions I've seen on drawings are wild, but as long as they put the correct nomenclature (Fβ, fu, etc....) I can always get them what they need. 

I mean, I'm looking at a gear spec right now that says "Tooth Alignment - Total" for the Fβ, and then they next one says "Total Lead Variation" for the Fβ. 😅
