Sub: 'Finding Tooth Ratios' article published in Nov/Dec 1985 issue Let us congratulate you and Orthwein, W.C. for publishing this superb article in Gear Technology Journal. We liked the article very much and wish to impliment it in our regular practice.

Two major processes used for cutting gears, hobbing and shaping. This article describes advanced machine design and cutter materials for gear shaping.

One of the current research activities here at California State University at Fullerton is systematization of existing knowledge of design of planetary gear trains.

Three things have happened in the last few weeks, that lead me to believe the worst is over - not that great times are ahead, but that things will get better.

Hobbing is probably the most popular gear manufacturing process. Its inherent accuracy and productivity makes it a logical choice for a wide range of sizes.

Austempering heat treatments (austenitizing followed by rapid cooling to the tempering temperature) have been applied to nodular irons on an experimental basis for a number of years, but commercial interest in the process has only recently come to the surface.

Events from SME and AGMA, along with news from the gear industry.

Congratulations from a number of readers who are impressed with the new magazine.
