Abstract

The article concerns the machining process of the titanium alloy Ti6Al4V according to the norm DIN W. Nr 3.7164 and the choice of a suitable cutting tool. For machining the alloy, replaceable cutting inserts indexed in accordance with the standard ISO - CNMG 120408, with varying geometry of the chip breaker, were used in pre-defined cutting conditions. The experimental part was performed to define the influence of the chip breaker geometry at the process and magnitude of the dynamic force at outer longitudinal machining of the titanium alloy Ti6Al4V. For measuring the force and setting the magnitude of individual components of the cutting force three-component piezoelectric dynamometer KISTLER 9257B was used during the machining process. Based on the measured and processed values, the lowest and the highest force impact on the surface of the machined material was specified and also the load on the cutting edge at machining the titanium alloy Ti6Al4V.
