Designing of a tool for machining multiple hearth furnace arms

Abstract

The purpose of the article was to establish the design of a cutting tool for the machining of multi-
shell furnace arms, in which the final finish is achieved by means of roughing abrasive discs.
Taking into account the stress and tension states to which the cutting tool is subjected, a material used
for these purposes was
selected, and the geometric variables and
parameters that guarantee
a safety factor, in accordance with the technological requirements of the process, were also analyzed. In accordance with the elements previously mentioned, a milling cutter was designed  for the  machining of the working areas of these arms. The loads and moments acting  on its were determined by  the analytical method and the von Mises tensile stresses by the finite element method, which were compared with the  admissible ones obtained,  giving the desired results.
