Tooling & Workholding: Software thought backwards
There are already an infinite number of different gear geometries. Nevertheless, engineers are constantly coming up with new variants. For […]
Hob quality basics
The quality of a hob directly affects the final quality of the gear it generates. AGMA has developed a standard […]
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 […]
Tooling & Workholding: Why precision clamping matters
Precision clamping devices can be custom designed for applications and can vary over a wide range of industries. David Jones, […]
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 […]
Conjugate Action Law in Intersected-Axes Gear Pairs and in Crossed-Axes Gear Pairs
The article deals with the kinematics and the geometry of geometrically-accurate gearing (with perfect gearing). Considered at the beginning for […]
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, […]
