Abstract: A method for calibration of a working point (TCP) for tools on industrial robots with a calibration device includes the use of at least two light barriers with an azimuth angle (?) greater than zero at an angle to each other and intersecting at an intersection point.

Abstract: The invention relates to a method for calibration of a working point (TCP) for tools (13) on industrial robots (8) with a calibration device (1), comprising at least two light barriers with an azimuth angle (?) greater than zero at an angle to each other and intersecting at an intersection point (R), comprising the steps: a) fixing set TCP positional coordinates for a set working point (TCP<SB>SOLL</SB>) for the tool (13), relative to a tool reference point (W) of the industrial robot (8) and a TCP coordinate system relative to the working point (TCP), b) moving the tool (13) directly to the set working point with relation to the TCP coordinate system through the light barriers, such that the tool tip of the tool (13), corresponding to the working point (TCP), interrupts the light E barriers, c) recording actual TCP positional coordinates on interruption of a light barrier, d) determination of the difference between the set TCP positional coordinates for the interruption of the light barriers for
