       Our Excel program generates enveloping surfaces for accurate simulation of the 3-d tooth contact pattern on standard CAD/CAM software as shown here on examples of spiral bevel and crown face gears.

The tooth contact pattern simulation is commonly used for inspection of production gears. If you machine gears from our 3d models the shape and location of the tooth contact pattern on the real gear will be identical to 3d contact pattern simulation on 3d model.

Localization and positioning of the tooth contact is commonly used in gear industry to compensate for misalignments in assembly.

We pioneered  contact pattern simulation in 3d in 1999. Today, our Excel program allows to simulate accurate 3-d model of the tooth contact on any standard CAD/CAM software.

     Our tooth contact pattern simulations have been recognised by the gear industry as the most accurate. The following tooth contact pattern simulations have been rendered in common CAD software with use of our Excel output.

There is an obvious advantage to use standards 3d CAD software for visualization. Any common CAD software visualize as nice as our examples here.   

With standard CAD software it is possible to do many engineering calculations about the tooth contact. For example, CAD allows to get properties of interference which corresponds to load distribution in the mesh, while the area of the contact can be also checked:

There are many ways to accurately model tooth contact. We prefer accuracy, simplicity and availability.
