Opportunity and Obligation

I was recently honored by the European Association of Machine Tool Merchants (EAMTM) at the organization's annual meeting this past June in Mallorea, Spain. The organization inducted me as a Fellow, EAMTM's highest honor, bestowed on members who have made significant contributions as volunteers serving the organization, which was originally founded in 1940. I felt especially honored, as I am only the 19th person and the second non-European to have been given this award.

Local 3-D Flank Form Optimizations for Bevel Gears

Optimizing the running behavior of bevel and hypoid gears means improving both noise behavior and load carrying capacity. Since load deflections change the relative position of pinion and ring gear, the position of the contact pattern will depend on the torque. Different contact positions require local 3-D flank form optimizations for improving a gear set.
