Abstract
This paper presents the procedure that DIMEG has set-up and tested for the reverse engineering of spiral bevel gears and related tools, with particular reference to the accuracy analysis applied to reconstructed CAD models. The work is part of a research project whose objective is the joint optimisation of forging and machining operations in gear manufacturing. Within the project the CAD model of prototypes, semi-finished and final products and related tools are required for simulation, manufacturing and testing. Some of these applications require an accurate mathematical representation of existing physical objects, and for this reason a particular effort was spent on the verification of the accuracy of the reconstructed CAD model. The procedure can be split up into three main steps: i) digitisation of functional surfaces on a reference tooth, using a coordinate measuring machine (CMM) equipped with contact probe, ii) reconstruction of complete solid model in CAD environment, and iii) verification of CAD model on CMM. Results of the accuracy analysis, advantages and limitations of this procedure are presented and discussed.
