Robots are a Mans best Friend
Pretty much everyone
old enough to utter the
familiar, dual syllabic refrain of “beep boop” in the electro-mechanical,
monotone pitch from every sci-fi movie ever made has the same idea of what a
robot looks likes.
On the Cutting Edge
Sentences that start off with
some variance of “I don’t want
to brag, but…” are generally a
good indicator that it’s precisely
what the speaker intends to
do and typically end with bold
proclamations that are immediately
and eminently quotable — the kind of quotes perfect for beginning a feature
story with an eye-catching artistic flourish.
Hub of the Gear Industry
The name Gleason is practically synonymous with gear manufacturing. Since the company was founded in 1865, the technology of gear manufacturing has
been its focus, its core and its competitive advantage.
Getting in Gear with the Chain of Innovations
At the dawn of the Industrial
Revolution, so-called mechanics
were tasked with devising the precise methods that would make mass production possible. The result was the first generation of machine tools, which in turn required improved tooling and production methods.

Non-Involute Gearing, Function and Manufacturing Compared to Established Gear Designs
Introduction
The standard profile form in cylindrical
gears is an involute. Involutes are
generated with a trapezoidal rack — the
basis for easy and production-stable
manufacturing (Fig. 1).
On the Correlation of Specific Film Thickness and Gear Pitting Life
The effect of the lubrication regime on gear performance has been recognized, qualitatively, for decades. Often the lubrication regime is characterized by the specific film thickness defined as the ratio of lubricant
film thickness to the composite surface roughness. It can be difficult to combine results of studies to create a cohesive and comprehensive data set. In this work gear surface fatigue lives for a wide range of specific film values were studied using tests done with common rigs, speeds, lubricant temperatures, and test procedures.
Quality and Surface of Gears Manufactured by Free-Form Milling with Standard Tools
The recently available capability for the free-form milling of gears of various gear types and sizes — all within one manufacturing system — is becoming increasingly recognized as a flexible machining process for gears.

Coffeegate (Publishers Page)
The other day I went to Starbuck’s and ordered
my usual four shots of espresso, straight up. I know
what you’re thinking: that’s a lot of caffeine, especially for someone
as naturally energetic as I am. But after years and years, I
may have built up a tolerance to the caffeine. I picked up the
espresso habit as a much younger man, when I worked for
Daldi & Matteucci (DEMM) in Italy back in the ’70s. And I’ve
stuck with it ever since.

Little Gears, Big Picture (Addendum)
If there wasn’t such a thing as air (seriously, who even needs it?), gears might stand alone as the most ever-present entities on earth. They are literally everywhere you turn — a universal, inescapable part of the world we live in, sort of like Justin Bieber but with less hair gel and electronic synthesizers.
