FEATURES

Company Profile: STD Precision Gear & Instrument, Inc.

From cutting gears in a cellar to sending them into space, this company is known for tackling the tough jobs, and doing it right the first time.

Entrepreneurs are hardwired to detect opportunity, and that certainly describes James Manning, president of STD Precision Gear & Instrument, who’s taken a company launched in his cellar to one that’s supplied gears currently in use aboard the International Space Station. It all started in 1984, he says, with an interesting phone call from his accountant. […]

A Solution for Gear Bore Accuracy

A new generation of machines from Sunnen has become the "ten millionths" solution for bore accuracy, providing OEMs with increased product performance.

Did you hear about the amazing new technology that enables gear makers to achieve bore accuracies measured in ten-millionths and even “fix” bore geometries and achieve high process capabilities (Cpk), all in automated, high-throughput production? To tell the truth, this mystery technology isn’t really new. Conventional honing has been hiding in plain sight for about […]

Molded Plastic Gear Design

Basic differences between plastics and metals have important implications for gear and transmission designers. Ticona understands these differences, and discusses them here.

Gear design and development is a complicated art. Ignore or miscalculate the operating and environmental effects and the likely result is a gear set that doesn’t mesh properly, which will cause excessive noise, gear failure, or both. This is especially true for molded plastic gear design, where the initial engineering effort is greater than that […]

A New Angle on Cutting Bevel Gears

With manufacturing processes in a constant state of evolution, the following technical paper describes a novel concept involving the enveloping cutting of straight bevel gears.

Straight bevel gears are widely used in the design of automotive differentials, as well as in other applications. In high volume production, Revacycle cutters are used to cut straight bevel gears. This process of cutting bevel gear teeth is illustrated in Figure 1. Most Revacycle-cut gears are produced with one completing operation using a cutter […]

Terry McDonlad: Site Safety

Workplace safety isn't just a concern for big companies with thousands of employees. Even the smallest operation can benefit from OSHA's on-site consultation service.

Sometimes when we talk about the importance of developing safety programs—along with manuals, equipment, signage, etc.—it can seem like we’re only focusing on big companies with hundreds or even thousands of employees. And while it’s certainly true that the more people you have on the employment roles to protect, the more important it can be […]

Gear blanks are subject to numerous forces during the manufacturing process, all of which must be understood to achieve the desired result

The universal demand for gears necessitates that they be produced in many geometric forms, numerous materials, and a wide range of quality levels that require different manufacturing methods. Cast gears are formed from molten metal; wrought gears are shaped by the deformation of hot or cold metal; metal powder gears are molded from compressed powders […]

Vice President of Sales, ShouldCost LLC

Your website and service is named for a concept known as “should-cost” modeling. Could you explain? “Should-cost” estimating, or analysis, was actually developed by the Air Force back in 1960 when it conducted a study involving one of its biggest suppliers in order to determine ways to save money by increasing efficiencies. One of the […]

PRODUCT SHOWCASE: High-Accuracy CMM-Based Laser Scanner from Wenzel

The requirements for quality assurance have increased with 3D technologies. Previously all major dimensions could be taken from a 2D drawing for tactile measurement, which is no longer the case today. Modern 3D drawings include little in the way of explicit dimensions. The curves of the freeform surfaces are almost impossible to verify using traditional […]
