Best Practices in Manufacturing
There's an old expression that the whole is greater than the sum of its parts. That's not always true in manufacturing. Each step in the manufacturing process is designed to output exactly what is needed to complete the finished product. It doesn't matter whether it's discrete, batch or process. The end result is supposed to be the sum of each of dozens of steps in the process.

Clutches and brakes couple, decouple, accelerate, and decelerate rotating machine components and maintain them at proper speed. The functions of each are so similar that their rolls are often interchangeable. Whether the clutch/brakes are mechanically, electrically, or fluid power actuated, they are considered mechanical devices because they transmit mechanical power.

Learning from bearing failure
When a bearing in a critical piece of equipment fails prematurely, a maintenance specialist knows the failure usually indicates there is more here than meets the eye. What the untutored eye sees is a failed bearing and little more. However, a premature bearing failure is symptomatic of other problems that, if left untreated, will cause the same kind of failure to occur again.

Band control The solution submitted in the December issue titled "Band Control" is a good idea. US Patent # 4,746,011 was issued to me on May 24, 1988, for this safety problem solution. I'd like to point out that the idea that was submitted had been tried during development, but we found the results were still too chancy and it was difficult to use.
Predictive Maintenance Technologies
The start of predictive maintenance (PdM) may have been when a mechanic first put his ear to the handle of a screwdriver, touched the other end to a machine, and pronounced that it sounded like a bearing was going bad. We've come a long way since then with a variety of technologies for analyzing what's going on inside equipment, but the need for a knowledgeable, experienced person to use the ...

Simple solutions to common maintenance problems
Most short cuts are based on skillful application of common sense, so a typical reaction to a new tip is "Why didn't I think of that?" Ideas for faster, easier, less expensive (and perhaps better) ways to deal with maintenance tasks deserve to be shared. That's why Plant Engineering magazine publishes "Tips & Tricks" and "Simple Solutions." If you have one or more tips that you are willing to share with fellow professionals, see "How to submit suggestions" at the end of this article. All submissions received during the year will first be considered for Plant Engineering's annual September "Tips & Tricks" presentation, where entries voted tops by readers receive substantial cash awards. Whether they win a prize or not, ideas deemed useful will be published in "Tips & Tricks" or "Simple Solutions."
