Figure 2-3 Axial velocity change on block transition
2.3.3 Rounding according to path criterion
Blending
Rounding means that an angular block transition is changed to a tangential block transition
by a local change to the programmed feedrate.
Rounding replaces the area in the vicinity of the original angular block transition (including
transitions between blocks inserted by the CNC) by a continuous contour. In this case, it is
not only the geometry axes that are taken into account, but all machine axes, which are
traversing synchronously. The rounding function therefore smoothes the traversing path of
orientation axes as well as general velocity step changes in synchronized axes.
