Abstract

In a method for continuous-path control in at least two linear axes and at least one angle axis, the movement of a tool relative to a workpiece is predefined by a parts program for a numerical control. The velocity control in the numerical control is performed separately for the linear axes and the angle axes. Deviations in the movement between the tool and the workpiece resulting due to the separate velocity control may be corrected by compensation movements of the linear axes. The separate velocity control for the linear axes and the angle axes may be achieved by rounding the velocity profiles in the angle axes more significantly than the velocity profiles in the linear axes. A measure for the rounding for velocity profiles may be predefined separately for the angle axes and the linear axes.
