THE INFLUENCE OF MEASURED POINTS POSITION ON TOOLS PROFILING WHEN USING Bezier polynomial approximations
Gabriel FRUMUŞANU, Nicolae OANCEA
Abstract: Practical necessities can, sometimes, impose us to solve the problem of profiling a 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, 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, when a circular profile has to be generated, together to a specific algorithm which allows finding rack-tool profile, by using Bezier polynomial approximation; the influence of measured points position onto problem solution precision is also analyzed by using a dedicated soft.
Key words: rack-tool profile, Bezier approximation, discrete points, circular profile.
