Análise e comparação do torque filete a filete no rosqueamento interno por machos de corte.

Abstract

The thread process is responsible for internal and external threads creation which are of large application in several areas. Even though its large usage in industry, there are few papers about this process. In this paper, it was carried out torque fillet by fillet measurements over the chamfer portion of the tap and the torque comparation between tools from two distinct manufacturers. It was used M 10 x1,5 HSSE straight flute taps, with and without coating in tapping process on a grey cast iron GG30, in order to analyse the relation between the number of fillets in the tap’s chamfer and its geometry in torque signal behaviour.
