1 Real-World Job Training the Lean Way -- And Loving It (September 2011)

Make no mistake -- lean manufacturing is here to stay. And no wonder. As a fiercely competitive global economy continues to alter companies’ “Main Street” thinking, that relatively new dynamic is spurring the need for “I-need-it-yesterday” production output. And for increasingly more industries -- big or small -- that means getting as lean as you can, as fast as you can.

2 Going Lean Is One Thing (June 2007)

Google “lean manufacturing” and you will find a virtually endless font of information regarding formal lean implementation. You’ll see definitions for Japanese words such as kaizen, gemba, muda, mura, kanban, and so on. You will also find other variations or iterations of lean, e.g.: Six Sigma, Lean Sigma, TPS (Toyota Production System), TOC (Theory of Constraints), JIT (Just in Time), and others.

3 Design of a Flexible and Lean Machining Cell, Part II (August 2013)

Job shops may be ill-advised to undertake a complete reorganization into FLEAN (Flexible and Lean) cells. A FLEAN cell would (i) be flex-ible enough to produce any and all orders for parts that belong in a specific part family and (ii) utilize lean to the maximum extent possible to eliminate waste.

4 A Quick-Start Approach for Implementing Lean in Job Shops (October 2012)

In the August issue, we examined the lean tools that will and will not work in high-mix, low-volume manufacturing facilities. Now, we will examine how to implement the tools that will work in the job shop with an approach that expands the capabilities of value stream mapping.

9 Design of a Flexible and Lean Machining Cell, Part I (June/July 2013)

Although a cell is dedicated to produce a single part family, it must have the requisite equipment capabilities, routing flexibility, cross-trained employees and, to the extent possible, minimal external process dependencies. Cells are often implemented in job shops since they provide the operational benefits of flowline production.

10 Job Shop Lean (January/February 2013)

A look at three gear industry companies at varying stages in the journey.

18 Got Lean, Six Sigma - Here's Another Theory (March/April 2009)

Most readers are at least familiar with continuous improvement programs such as lean and six sigma. Perhaps your shop or company is well along in the implementation of one or the other—if not both. But what about theory of constraints (TOC), introduced in Dr. Eliyahu Goldratt’s 1984 book, The Goal? Despite its rather negative-sounding name, this continuous improvement process has much to offer manufacturers of all stripes. And when combined with lean and six sigma, the results can be dramatic. Dr. Lisa Lang, a TOC consultant and speaker, explains why and how in the following Q&A session with Gear Technology.

19 Wind Turbines: Clean Energy, but Energy Efficient (June/July 2011)

We talked energy efficiency with some major players in the lubricants industry— but with a focus on their products’ impact regarding energy efficiency of gears and gearboxes in wind turbines.

20 Journey to the Land of Manufacturing Milk and Honey--What Are You Waiting For? (July 2008)

How lean manufacturing principles can help transform your gear manufacturing business.

21 Growing Pains - Renewables Hang on in Turbulent Energy Market (June/July 2012)

The turbines are still spinning. They’re spinning on large wind farms in the Great Plains, offshore in the Atlantic and even underwater where strong tidal currents offer new energy solutions. These turbines spin regularly while politicians and policy makers— tied up in discussions on tax incentives, economic recovery and a lot of finger pointing—sit idle. Much like the auto and aerospace industries of years past, renewable energy is coping with its own set of growing pains. Analysts still feel confident that clean energy will play a significant role in the future of manufacturing—it’s just not going to play the role envisioned four to five years ago.

22 The Call of Cuba (May 2012)

I’ve had the great fortune to visit many countries and experience their cultures, and I often tell stories based on those experiences. But when I begin to tell people about my most recent trip—to Cuba—their eyes light up, their attention sharpens and they lean forward with great interest and curiosity.

23 Innovative Induction Hardening Process with Pre-heating for Improved Fatigue Performance of Gear Component (July 2014)

Contact fatigue and bending fatigue are two main failure modes of steel gears, while surface pitting and spalling are two common contact fatigue failures -- caused by alternating subsurface shear stresses from the contact load between two gear mates. And when a gear is in service under cyclic load, concentrated bending stresses exist at the root fillet -- the main driver of bending fatigue failures. Induction hardening is becoming an increasingly popular response to these problems, due to its process consistency, reduced energy consumption, clean environment and improved product quality -- but not without issues of its own (irregular residual stresses and bending fatigue). Thus a new approach is proposed here that flexibly controls the magnitude of residual stress in the regions of root fillet and tooth flank by pre-heating prior to induction hardening. Using an external spur gear made of AISI 4340 as an example, this new concept/process is demonstrated using finite element modeling and DANTE commercial software.

24 Gear Expo '93 - A Wise Investment (July/August 1993)

Gear Expo '93 - another trade show, another plea to send people and/or equipment out of town, away from the office or plant. Another bid to spend time, money, and effort. Oh, please! Hasn't anybody heard that these are the "lean and mean" '90s?

25 Bigger and Better Than Ever (July/August 1999)

Gear Expo 99, AGMA's biennial showcase for the gear industry, has left the Rust Belt this year and landed in Music City U.S.A., Nashville, Tennessee. The event, with exhibitors from around the globe showing off the latest in gear manufacturing as well as metal working processes, will be held at the Nashville Convention Center, October 24-27, 1999. According to Kurt Medert, AGMA vice president and Gear Expo show manager, "In choosing Nashville, AGMA;s Trade Show Advisory Council found a city that is an excellent trade show site. It has the right mix of convention center, nearby hotels, and a clean downtown area with entertainment readily available for the exhibitors and visitors alike. Nashville is in the heart of southern industry, which we see as a focus of growth for the gear industry and its customers."

26 Plan Ahead (January/February 1996)

Indianapolis is a nice city. No. It's a great city for a convention. The facilities and the city are modern, clean and bright. The Convention Center is easy to get to by either car or plane, and its central location in the heart of town and the enclosed skyway system between it and major hotels put visitors close to amenities like restaurants, shopping and entertainment. The people are friendly and go out of their way to make visitors feel welcome.

27 Gear Heat Treating in the 90s: Beyond Black Magic (March/April 1995)

Heat Treating - The evil twin of the gear processing family. Heat treating and post-heat treating corrective processes can run up to 50% or more of the total gear manufacturing cost, so it's easy to see why, in these days when "lean and mean" production is the rage, and every part of the manufacturing process is under intense scrutiny, some of the harshest light falls on heat treating.

29 How's Your Lead Time (July 2007)

The gear companies enjoying the most success in today’s global market are those that firmly believe quality is much more than expert craftsmanship and foolproof inspection methodologies.

30 Enterprise Excellence: Are We There Yet (September/October 2010)

When the term, “what you see is what you get” is applied in the computer industry, it means that users or customers are able to see their end results without the encumbrances of complicated software code that enables this function. Software works behind the scenes ultimately to produce transparency and the desired effects. In many ways, this concept should be extended to the relationships that exist between suppliers and buyers and even among internal company departments.

31 Environmentally Safe Fluids for Industrial Cutting, Lubrication, & Cleaning (January/February 1993)

Not long ago, many manufacturing managers thought sensitivity to environmental protection standards meant additional expenses, decreased productivity, and a plethora of headaches and hassles.
