1 Industry News (July 2014)

The complete Industry News section from the July 2014 issue of Gear Technology.

2 GT Extras (July 2014)

See the latest video from Slone Gear International, plus read about the gear industry's unsung heroes in the latest blog post.

3 Untraditional Gear Machining (October 2013)

Look beyond the obvious, and you may well find a better way to machine a part, and serve your customer better. That’s the lesson illustrated in a gear machining application at Allied Specialty Precision Inc. (ASPI), located in Mishawaka, Indiana.

4 Getting Wired into EDM (June 2010)

Technology emphasizes high accuracies and improved surface finishes.

5 EDM Specialty Gears (May/June 1996)

The capabilities and limitations of manufacturing gears by conventional means are well-known and thoroughly documented. In the search to enhance or otherwise improve the gear-making process, manufacturing methods have extended beyond chip-cutting - hobbing, broaching, shaping, shaving, grinding, etc. and their inherent limitations based on cutting selection and speed, feed rates, chip thickness per tooth, cutting pressure, cutter deflection, chatter, surface finish, material hardness, machine rigidity, tooling, setup and other items.

6 Alternative Gear Manufacturing (July/August 1998)

the gear industry is awash in manufacturing technologies that promise to eliminate waste by producing gears in near-net shape, cut production and labor costs and permit gear designers greater freedom in materials. These methods can be broken down into the following categories: alternative ways to cut, alternative ways to form and new, exotic alternatives. Some are new, some are old and some are simply amazing.

7 Racing Circuits (May/June 1996)

Zero to 125 MPH in five seconds. Maximum speed of 211 MPH. Seven-second pit stops. Formula One racing is a high-adrenalin sport - one which demands peak performance from drivers and machines alike.

8 Generating Precision Spur Gears By Wire EDM (May/June 1996)

Over the past decade, the wire electrical discharge machine (EDM) has become an increasingly important tool for machining non-standard shapes. It has even been used to cut gears and gear cavities for plastic molds. While generally accepted as a quick and versatile method for cutting spur gears, the EDM gear has lacked the precision of a mechanically machined or ground gear. We suspected that many of the errors associated with these gears were caused by inexact setup procedures, poor tool path control and improper cutting parameters. We decided to test the potential for the wire EDM to make the most accurate gear possible.

9 The Politics of Denial (September/October 1996)

A good many things bother me about election years - the annoying sound bites, the negative commercials, the endless political over-analysis. But what bothers me most about the coming election is this: So far (when I'm writing this, it's admittedly early in the campaign) there's little or no talk about what is one of the most critical national issues of the next thirty years - our growing government debt.

10 Reader Dialogue: Functional Measurement of Gears; More Good Gear Books (September/October 1992)

From time to time, the editors of "Shop Floor" receive correspondence from readers relating to particular articles they have written for past issues. As one of the purposes of this column is to provide a forum for the exchange of ideas, we reproduce here two of these letters and their replies. The subject of the first is the functional measurement of gears. (See Gear Technology, Sept/Oct, 1991, p. 17) Robert E. Smith writes the reply.

11 Rattle: Addressing Gear Noise in a Power Take-off (January/February 2012)

At Muncie Power, the objective of noise and vibration testing is to develop effective ways to eliminate power take-off (PTO) gear rattle, with specific emphasis on PTO products. The type of sound of largest concern in this industry is tonal.

12 Multifunctional Advancements (January/February 2012)

The latest in big gear machining with DMG/Mori Seiki.

13 Liebherr's LDF350 Offers Complete Machining in New Dimension (November/December 2011)

The objective, according to Dr.- Ing. Hansjörg Geiser, head of development and design for gear machines at Liebherr, was to develop and design a combined turning and hobbing machine in which turning, drilling and hobbing work could be carried out in the same clamping arrangement as the hobbing of the gearings and the subsequent chamfering and deburring processes.

14 Rotary Gear Honing (May/June 1987)

Rotary gear honing is a hard gear finishing process that was developed to improve the sound characteristics of hardened gears by: Removing nicks and burrs; improving surface finish; and making minor corrections in tooth irregularities caused by heat-treat distortion.

15 Gear Roll-Finishing (May/June 1987)

In this discussion of gear roll-finishing particular attention is called to the special tooth nomenclature resulting from the interaction between the rolling die teeth and the gear teeth. To eliminate confusion the side of a gear tooth that is in contact with the "approach" side of a rolling die tooth is also considered to be the approach side. The same holds true for the "trail" side. Thus, the side of the gear tooth that is in contact with the trail side of a rolling die is also considered to be the trail side.

16 All Hail Leonardo (June/July 2012)

The ultimate Renaissance man was also a gear man. Addendum pays tribute to Leonardo da Vinci.

17 Leonardo, the Engineer (January/February 1989)

These lines, interesting enough, are from the notebooks of an artist whose images are part of the basic iconography of Western culture. Even people who have never set foot in a museum and wouldn't know a painting by Corregio from a sculpture by Calder, recognize the Mona Lisa. But Leonardo da Vinci was much more than an artist. He was also a man of science who worked in anatomy, botany, cartography, geology, mathematics, aeronautics, optics, mechanics, astronomy, hydraulics, sonics, civil engineering, weaponry and city planning. There was little in nature that did not interest Leonardo enough to at least make a sketch of it. Much of it became a matter of lifelong study. The breadth of his interests, knowledge, foresight, innovation and imagination is difficult to grasp.

18 The Merits of Multifunctional Machining (January/February 2011)

Higher productivity, faster setup times and single unattended operations are just a few of the capabilities gear manufacturers seek in the multifunctional machine tool market.
