Direct Digital Simulation for Gears

     I have been developing 3d gear modeling software since 1986. Worked on gears for top aerospace and automotive like BA, LMT, GM, F,... for over 30 years. Incorporated as Spiral Bevel in 2008. Customers in 50+ countries.
     I personally answer email and calls. My local time is New-York time.
