Abstract

In a method for calibrating machine units in machine tools and robotic devices that perform a parallel-kinematic motion in a motion space, the position of the machine unit relative to a reference system is determined from the totality of the positions of all drives operating in parallel of the machine units, whereby each drive moves relative to the reference system a single drivetrain that is associated exclusively with the drive. The machine units can be calibrated using a robust and efficient iterative process that generates a kinematic transformation.
