It is with great sadness we share the passing of Robert (Bob) Smith. Bob was a valued member of the AGMA Gear Accuracy technical committee, representing Gleason Works, where he worked as a gear engineer for 38 years. Also, since 1991, he was a Gear Technology technical editor. For those who wish to share any memories or condolences, please visit his obituary page.
Here is a link to one of Bob's Gear Technology pieces, "Measuring Pitch Diameter," written with his light touch of humor and inimitable voice of myth-busting authority.
