Abstract

A one-dimensional, actual-value-specific path parameter F.sub.I (t) is derived from a motional function F.sub.B (t) to trigger switching functions related to position during the movement along a trajectory path of a numerically controlled system, for example a robot or a machine tool. This allows triggering of a switching operation such as switching on a welding or bonding tool with high precision at the actual position of the tool.
