Influencia del ángulo de posición en el diseño del rompevirutas: estudio de herramientas de torneado dinámico y de alto avance en Inconel

Abstract

Dynamic turning is a recent technology that allows inserts

with different cutting edges to be used and the side cutting

edge angle to be modified by controlled spindle rotation and

synchronised variation of the cutting parameters. This makes

it possible to eliminate downtime by reducing tool changes.

Chip breaking is a relevant fact in the turning of aeronautical

parts, as it allows a higher heat dissipation performance when

working with heat-resistant superalloys, materials that degrade

inserts rapidly. An initial study has been carried out, using

different fixed side cutting edge angles, to test the chipbreaker

performance of an experimental dynamic turning insert in

order to adapt its design to the machining of aeronautical

components, obtaining that, although the cutting performance

is good, the chipbreaker does not perform correctly in finishing

conditions, and therefore it must be redesigned by reducing its

distance to the cutting edge.
