Set-Up Procedure to Generate Spiral Bevel Gears by Computer Aided Manufacturing Techniques
The relative position between cutter and blank, at the beginning of the spiral bevel gears generation motion is very important. If this starting point is miscalculated or the correct set-up is not observed, the whole tooth profile is affected.
This paper describes a new technique, devised to provide an accurate and fast setup to generate spiral bevel gears in a computer controlled milling machine. The whole set-up prodedure for rough cut, to finish the concave and the convex flanks as well as the mathematical approach associated with the problem is presented.
The experimental results of this research have shown a reduction in the set-up time of, at least, 80% and a tooth bearing well placed.
