Abstract: An accurate design and modeling approach of gear is put forward using the generation method. The gear tooth profile is obtained by simulating rack cutter machining cylindrical gear tool path in VS2005 compiled using C#. The root cutting graphics, the addendum sharpening, the addendum edge fixing and other gear design processes can be checked with the gear profile. The gear modeling enveloping points on grid coordinates is exported to UG, the grid envelopes are generated, and a mathematical model for gear is establish.
Key words: generation method; coordinate transformation; grid envelope; C#; UG grip
