The machine set up are very sophisticated when cutting the spiral bevel gears

it is quite important that how to quickly detect the mismachining error. It can not only supply accurate correction data and adjust the position and shape of the contact pattern but also increase the cutting quality. So it is necessary to analyse the surface information.By the use of Visual C++6.0 and Matlab 6.5

the article completed the testing program about bull wheel tooth surface coordinate

and it can correctly and rapidly test the tooth surface coordinate. The programe provides an effective path for the gear cutting.
