The adaptronic precision positioning technology is applied to the fitting of rotation-symmetric components such as gearwheels in a hard turning process in order to compensate eccentricity. Distorted gearwheels, showing e.g. a significant quench distortion, cause a malposition in the chuck during clamping. This malposition leads to low quality workpieces or scrap in the hard turning process. To compensate the malposition of the workpieces, a new technology for precision positioning within the rotating chuck is being researched. In the introduction, the motivation of the preceding research project “Allowance-oriented precision positioning” and the framework of the adaptronic precision positioning technology are summarized. Next part is the description of the system’s components, beginning with the principles and the redesign of the mechatronic chuck. Completing the adaptronic precision positioning technology, the optical metrology, the data processing and automation aspects are shown in the following part. Afterwards, a short summary concludes this paper.Copyright © 2009 by ASME
