A method for correcting measurement errors when measuring a tool or workpiece, particularly in an automated process, such as in a mounting device for automatic chucking and unchucking of a tool in a tool holder, especially in a shrink-fitting device, a measuring device for measuring a tool or workpiece, and a mounting device for automatic chucking and unchucking of a tool in a tool holder, especially in a shrink-fitting device.
The method corrects systematic measurement errors in shrink-fitting devices by using arithmetic means and telecentric measuring units, ensuring accurate tool and workpiece dimensions for precise machining processes.

Abstract
The present invention provides a method for correcting measurement errors when measuring tools or workpieces, a measuring device for measuring tools or workpieces, and a mounting device for automatic chucking and unchucking of tools in a tool holder. [Solution] In order to avoid or correct measurement errors when measuring a tool or workpiece, a point on the tool or workpiece that identifies the tool or workpiece, in particular the highest point of the tool or workpiece with respect to its longitudinal axis, is measured, and the tool or workpiece is rotated from a specified starting rotation position by a specified rotation angle around its longitudinal axis. Subsequently, the mean value, in particular the arithmetic mean, is determined from the measured values of the measured value progression, and the error correction (measurement) value of the point that identifies the tool or workpiece is determined using the determined mean value, in particular the determined arithmetic mean.
