Pretreatment of reverse engineering modeling of end face spiral gear

Then preprocess the reverse engineering point cloud file of end face spiral gear, remove the miscellaneous points, and smooth the surface to a certain extent. After the treatment, the reverse engineering point cloud of the end face spiral gear is sliced, and then the smoothing treatment is carried out again. The final effect is shown in the figure.

In the figure, we can observe that the basic geometric structure of the reverse engineering model of the end face spiral gear has been constructed, but there are still surface breaks and defects in the tooth part of the end face spiral gear. Although these defects can be further weakened to a certain extent through the smoothing and repair function in the software polygon function, excessive smoothing may reduce the accuracy of end face spiral gear teeth, especially the tooth surface. Excessive pursuit of the perfection of patch model will greatly affect the accuracy of later modeling.
