Research on Cutter’s Position and Pose for Chamfering Spiral Bevel Gear Addendum
The cutter’s position and pose are key elements for chamfering addendum automatically and a new method for calculating the cutter’s position and pose is as follows: 1) Finding the chamfering boundary curves of addendum by offsetting the two top curves (convex and concave) of spiral bevel gear addendum respectively; 2) Dispersing the chamfering boundary curves; 3) Calculating the center position of the tangent circle along the chamfering boundary curves and taking this as the cutter’s center; 4) solving the tilt angle through the center position and the dispersed points on boundary curves. The proposed method lays foundation for chamfering automation.
