Gear Grinding Gets Integrated at IMTS 2012
The latest machines, tooling and technology for gear grinding were featured at IMTS 2012.
Center Distance Variations for Internal Gears
While external involute gears are very tolerant of center distance variations, what are the center distance constraints for internal gears?
What are the manufacturing methods used to make bevel gears used in automotive differentials?
Pitting Resistance of Worm Gears: Advanced Model for Contact Pattern of Any Size, Position, Flank Type
An experimental and theoretical analysis of worm gear sets with contact patterns of differing sizes, position and flank type for new approaches to calculation of pitting resistance.
Repair of High-Value, High-Demand Spiral Bevel Gears by Superfinishing
Following is a report on the R&D findings regarding remediation of high-value, high-demand spiral bevel gears for the UH–60 helicopter tail rotor drivetrain. As spiral bevel gears for the UH–60 helicopter are in generally High-Demand due to the needs of new aircraft production and the overhaul and repair of aircraft returning from service, acquisition of new spiral bevel gears in support of R&D activities is very challenging. To compensate, an assessment was done of a then-emerging superfinishing method—i.e., the micromachining process (MPP)—as a potential repair technique for spiral bevel gears, as well as a way to enhance their performance and durability. The results are described in this paper.
My Glass is Half Full (Publishers Page)
Publisher Michael Goldstein is confident that the manufacturing economy will continue to grow throughout next year, no matter who wins the 2012 presidential election.
A Quick-Start Approach for Implementing Lean in Job Shops (Voices)
In the August issue, we examined the lean tools that will and will not work in high-mix, low-volume manufacturing facilities. Now, we will examine how to implement the tools that will work in the job shop with an approach that expands the capabilities of value stream mapping.

What We Learned @IMTS (Addendum)
They only let the Addendum team on the show floor for one day (they said it was something to do with their liability insurance...), but here's what our intrepid team of gear fanatics noticed at IMTS 2012.
