Abstract

The contribution deals with the determination of the influence of the microgeometry of the cutting tool on the progress and size of the dynamic load of the system in the machining process. The experimental part was realized in conditions of longitudinal turning of aluminum alloy EN AW 2014. For machining alloys were suggested replaceable cutting inserts with pre-set microgeometry edge with mark CCGT 120408-AL and cutting conditions. By means of the mechanical adjustment of the microgeometry of brushing, the rounded edge was achieved for radius 0-5 μm, 10-15 μm and 20-25 μm for tested inserts. During the experimental activity of machining aluminum alloy, the dynamic load of the system was measured and evaluating for the effect of the individual parts of the cutting forces using the stationary piezoelectric dynamometer Kistler. The resulting cutting force was determined with respect to the radius of the rounded edge and the value of the feed of the cutting tool.
