Abstract. In the paper are presented the bases of a methodology for the
determination of all the geometric and constructive elements of the cutting tools
for the fellows cutter, tools having curve edges, starting from the getting of a solid
model 3D of the measured tool. There are shown the possibilities to obtain a 3D
model and the mathematical model of the geometric parameters control.
Key words: fellows' cutter, control, cutting tools, 3D model, geometry,
curved edges.
1. Introduction
Preoccupations concerning the increase of the standard, standard type and
special cutting tools’ production and preoccupations concerning new tools with
superior constructive functional performances represent a major tendency in the
manufacturing of machines. The software resources implicates the existence in
the system of a collection of organized information in order to assure not only
the complete design of the cutting tool but also the analysis, the syntheses,
comparison, modeling, simulation optimization, visualization, the optional
presentation of the partial results etc. So the modern design is made in order to
obtain a solid 3D model that is later automatically detailed in sections and views
2D. The existence of the solid model signify the spectacular increase of the
information's’ number permitting practically the total knowledge of the
positions of any point or surfaces from the element’s construction and of the
angles between directions or planes. This demarche ameliorates the tackling of
the cutting tools' design by means of the concurrent engineering.
