Ebaketa-erramintaren tenperaturak neurtzeko tornuko ebaketa eten bidezko fresaketaren simulazioa

Abstract

In this work, milling simulation through interrupted turning process approximation is carried out. The main objective is to obtain cutting tool temperatures in the tool rake surface during the cutting process. In order to obtain these values, the milling process is approximated by the turning process. It is possible to assume this simplification when a longitudinally grooved workpiece is turned. This way, turning interrupted processes can be equate to milling processes due to milling interrupted cutting singularity. The tests measurements were carried out with a K-type thermocouple located at 0,5mm from tool insert rake surface. The middle temperature value measured in the contact area will be estimated with a heat conduction theoretical model. Different trails with several cutting conditions are tested. Moreover, temperature difference between continuous and interrupted cutting for the same cutting time and cutting effective length is also studied.
