Polynomial contouring type 2

In the case of this contouring type, the contouring curve is dimensioned so that the curve can be run through with the specified percentage vb_proz of the programmed speed of the previous block (N20). For example, if vb_proz=75% and F=2000mm/min is programmed as the contouring feed rate and this is not limited by permissible axis speeds or accelerations of that axis, the contouring curve is run through at v_B=1500mm/min.

No kinematic transformations are considered in estimation of the corner distance.
