Inspection & Metrology: Laser interferometry – An enabling technology for optimized automated manufacturing

Technological advances over recent years have elevated metrology from being a “necessary evil” in manufacturing scenarios to enabling technologies, allowing […]

Tooling & Workholding: Improving tool holder performance

The four critical requirements for tool holders are clamping force, concentricity, rigidity, and balance for high-spindle speeds. When these factors […]

Long hob cost savings over the length of a job

Manufacturers consider many factors when shopping for a gear hob solution: What material is being cut? What is the pitch […]

Micro-skiving – (r)evolution of a known production process

Production of internally toothed gear wheels is possible in many different ways. Different techniques such as gashing, broaching, wire EDM, […]

Chamfer Hobbing Tools Up

In the last few years, chamfering and deburring have gained new respect and risen to a level of importance equal […]

Advantages of flat broaching machines

A broaching machine requires precision broaching tools to increase productivity and efficiency. New broaching tools can be expensive and difficult […]

Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing

Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear […]

Using simulation to evaluate part green shape to reduce distortion during plug quenching

Determining the heat-treatment geometry (green shape) for complex gears is not a trivial task. Mass distribution becomes critical in determining […]

Filling Some Gaps in Spline Design Guidelines: Centering, Friction, and Misalignment

Editor’s note: At the author’s request, some statements have been removed for clarity since the article was originally published in October, […]

Taking deburring to the next level

Once a gear is created, deburring becomes a necessary step to ensure a gear’s accuracy. Traditionally, deburring has been done […]

Lean Heat Treatment for Distortion Control

Controlling distortion is of key importance during the case hardening process for the production of gear components. By effective control […]

Inspection & Metrology: ‘We must never stand still’

Small series and prototype production at ZF Friedrichshafen AG create new challenges for quality control time and again: measurement programs […]
