Abstract: A method for continuous-path control includes predefining at least two global tolerances to a numerical control and predefining, to the numerical control, a tool path including support points, a non-continuously differentiable corner of the tool path being situated at each support point. The method also includes assigning, by a tolerance-assignment unit, one of the at least two global tolerances determined to the corner at each support point. A global edge tolerance may be predefined when the tolerance-assignment unit recognizes that the corner at the support point leads to an edge in a workpiece. A global curve tolerance may be predefined when the tolerance-assignment unit recognizes that the corner at the support point approximates a curvilinear, continuously differentiable curve. A global edge tolerance may be predefined to be smaller than a global curve tolerance.
