Algorithm to profile rack-tool for profiles known in discrete form by using Bezier polynomial approximations
Nicolae OANCEA, Gabriel FRUMUŞANU
Abstract: The methods used to profile rack-tool reciprocal enwrapped to a whirl of cylindrical or helical surfaces, as possibility to do the constructive design of tools to cut gears teeth, require knowing the analytical form of profiles to be generated. Practical necessities can, sometimes, impose us to solve this problem when only a limited number of points from generated profiles are known in discrete form. A solution to such a problem can be enounced if using Bezier polynomial approximation of rack-tool profile. This paper presents the rack-tool profiling problem enouncement together to a specific algorithm which allows finding rack-tool profile by using Bezier polynomial approximation together with fundamental theorems concerning profiles associated to rolling centrods enwrapping.
Key words: rack-tool profile, Bezier approximation, discrete points.
