Inspection & Metrology: Overcoming metrology bottlenecks in additive manufacturing

Undoubtedly there are many benefits associated with the use of additive manufacturing (AM) as a production technology. Across industries, manufacturers exploit the fact that,...

Build resilience by monetizing value

Unforeseen disruptions, market fluctuations, and macroeconomic issues. The last year alone has exposed the unpredictable nature of the market and supply chains. Even new competitors...

Tooling & Workholding: Patented considerations in High Torque tooling

It is common knowledge in the CNC manufacturing community that if you use V-Flange tooling, you use retention knobs, which are the critical interface...

Case study: To seek out faster shaping

The search for intelligent life on Mars took a big leap forward on February 18, 2021, when Perseverance, NASA’s latest Mars Rover, touched down...

Technical diagnostics of a gear hobbing technological system on diagnostic signs of deviations of...

The article reveals the main provisions of technical diagnostics of a gear hobbing machine system with CNC on the diagnostic parameters of the profile...

Influence of manufacturing variations of spline couplings on gear root and contact stress

Involute splines are widely used in mechanical systems to connect power transmitting gears to their supporting shafts. These splines are as susceptible as gears...

Reduction of the tonality of gear noise by application of topography scattering for ground...

The noise behavior of transmission is mainly caused by the excitation in the gear mesh. The standardized design and calculation methods for gears concentrate...

Gear forging opportunities

Forging has long been used to manufacture gears, particularly in the production of gear blanks, which often uses open-die forging, closed-die forging, and hot...

Load intensity distribution factor evaluation from strain gauges at the gear root

Strain gauges are commonly used to obtain the load intensity distribution on the flank of a gear mesh. The standard methodology consists in installing...

Hob quality basics

The quality of a hob directly affects the final quality of the gear it generates. AGMA has developed a standard covering the allowable tolerances...

Perfect Pitch

Gear manufacturers are turning to workholding to help reduce costs without compromising quality. Pitch Line Fixtures, for example, can be used to provide a...

Predicting Gear Sliding Losses

Gearbox efficiency is becoming increasingly important for vehicle manufacturers to help achieve their overall fuel savings goals. Enhancing gearbox efficiency is also critical in...

Lubrication and its role in gear-failure analysis

When gears fail, it is most often due to fatigue and overloading. The most common form of distress and failure is actual breakage, but...

Selecting a worm gear lubricant

To compete in the marketplace, engineers across all industries are being tasked with increasing gearbox efficiency. Modern designs therefore must achieve high-power transfer without...

Power Skiving with integrated cutter resharpening

Gear manufacturing by Power Skiving takes the traditional approach: After a cutter has reached its maximum wear, the operator changes the cutter, adjusts the...

A new approach for the calculation of worm shaft deflection in worm and crossed...

Worm gear drives are characterized by a simple design, which allows the realization of a high gear ratio within one stage. Furthermore, they are...

The commonalities and differences between helical ‘low-tooth-count gears’ and ‘multiple-start worms’

The article deals with geometrically-accurate worm gear pairs that feature line contact between tooth flanks of a worm gear and thread surfaces of a...

Multi-sensor metrology advances

Demand for accurate gears delivered on tight schedules is increasing. To keep pace, technology is continually advancing, enabling manufacturers to do more in the...

Documenting defects with greater accuracy

We are in an era where modern technology and automation are rapidly evolving and pushing out conventional hand-operated tools. The LED magnifying glass lamp...

Finding the ideal materials for gears

When designing an individual gear or a gear train, the choice of material will either be the primary factor on which the gear geometry...
