IMTS 2010: Pumping Blood into the International Manufacturing Community
If the free iPad giveaway from FANUC doesnâ€™t draw you in, the wall-to-wall new machine tool technology displays should have you stopped dead in your tracks. To be exact, there will be 1.2 million square feet of exhibit space that may have your jaw dropping. IMTS may be the last show you want to forget to bring walking shoes to.

A handy checklist of the booths that gear manufacturers might want to see.
An Interview with Thomas Koepfer
Publisher Michael Goldstein sat down with Dr. Thomas Koepfer, whose family company, Josef Koepfer & SĂ¶hne GmbH, was founded in 1867. Over the years, the Koepfer name has become one of the best-known in the gear industry, with company operations including the manufacture of gear machines, cutting tools and gears.
Building Repeat Business: What Gear Buyers Really Want from Gear Manufacturers
In this article, gear buyers have been given an opportunity to discuss quality, value, customer service and how gear manufacturers can improve business practices.
Tribology Aspects in Angular Transmission Systems, Part 1
"General Explanations on Theoretical Bevel Gear Analysis" is part 1 of an eight-part series from Gleason's Dr. Hermann Stadtfeld.
Crowning Techniques in Aerospace Actuation Gearing
One of the most effective methods in solving the edge loading problem due to excess misalignment and deflection in aerospace actuation gearing is to localize tooth-bearing contact by crowning the teeth. Irrespective of the applied load, if the misalignment and/or deflection are large enough to cause the contact area to reduce to zero, the stress becomes large enough to cause failure. The edge loading could cause the teeth to break or pit, but too much crowning may also cause the teeth to pit due to concentrated loading. In this paper, a proposed method to localize the contact bearing area and calculate the contact stress with crowning is presented and demonstrated on some real-life examples in aerospace actuation systems.
Optimizing Gear Geometry for Minimum Transmission Error, Mesh Friction Losses and Scuffing Risk Through Computer- Aided Engineering
Minimizing gear losses caused by churning, windage and mesh friction is important if plant operating costs and environmental impact are to be minimized. This paper concentrates on mesh friction losses and associated scuffing risk. It describes the preliminary results from using a validated, 3-D Finite Element Analysis (FEA) and Tooth Contact Analysis (TCA) program to optimize cylindrical gears for low friction losses without compromising transmission error (TE), noise and power density. Some case studies and generic procedures for minimizing losses are presented. Future development and further validation work is discussed.
Application Examples from "Optimizing Gear Geometry for Minimum Transmission Error, Mesh Friction Losses and Scuffing Risk Through Computer- Aided Engineering"
Examples from gears in wind turbine, automotive and industrial applications.
