Rough milling with the Vortex method reduces machining time

With high-speed rough milling, correct programming can prevent exceeding the limit value of the radial cutting width and breaking the tool. In curves and transitions, however, the cutting width can temporarily increase, while this is not what is needed. A new method now automatically ensures that the cutting angle remains constant in all circumstances, which brings some interesting advantages.

Milling tools have a certain useful cutting length. In theory, they can be used without any problems, provided that a limit value for the radial cutting width is not exceeded during the machining operation. If this does happen, there is a good chance that sooner or later the cutting tool will break, with the known consequences. When programming a pocket rough milling operation within a CAM system, it is perfectly possible to enter a large axial cutting depth and a small radial cutting width, also known as high-speed roughing. On straight sections of the milling path, the tool will maintain these settings, but in curves or transitions to the next section, the cutting width may temporarily increase while this is not required. Many CAM systems do not yet support the functionality to limit the cutting width in these places. And that is why the cutting depth is must necessarily limited by the CAM programmer. The disadvantage of this is that the cutting edge is not fully utilised and the machining time is increased.
