DESENVOLVIMENTO DE UMA ESTRATÉGIA DE MEDIÇÃO, BASEADA EM NURBS, PARA DETERMINAÇÃO DO ERRO DE ENGRENAGENS CILÍNDRICAS DE DENTES RETOS USANDO MMCs

Abstract

Nowadays, the need for products with high dimensional and geometrical accuracy demands narrow tolerance in other areas, mainly in the industry. In addition, Gears have been for many years one of the technologies for the transmission of power, mostly in the automobile, mechanical and aviation industry. Currently, the inspection of the profiles involving spur gears are made using CNC Coordinate Measuring Machines (CMMs) with rotary tables and software for dedicated measurements which can either be equipped with contact scanning sensors or not. In this regard, the motivation on this term paper is to develop a measurement strategy to inspect the said profile, check for errors and when necessary change the weight parameter. To this purpose, we use the mathematical tool NURBS, spur gears by using Coordinate Measuring Machine (CMM), CNC equipped with palpate touch trigger and point-to-point measurements. The experimental results show the efficacy, the advantages and disadvantages of the developed methodology.
