Abstract
The application of high precision measurement devices in combination with mechatronic positioning chucks provides for enormous progression in production technology. In the collaborative research centre 489 which is funded by the German Research Foundation (DFG) the precision forging of highly loaded components is researched. The workpiece under examination is a gear shaft. Due to the minimum stock of only 30 to 80 microns the workpiece has to be precisely aligned before hard machining of the function elements. Therefore, two sensors in combination with a newly designed precision positioning chuck with integrated piezo actuators have been directly integrated into the machine tool. Due to the ability to measure steep angles, conoscopic sensors have been selected to ensure a reliable measurement of the toothing. After clamping the workpiece the profiles of the function elements are measured in several sections. With the help of specially adapted best-fit algorithms a three-dimensional vector is calculated. This vector contains the necessary adjustment information to relocate the workpiece and put it into the optimal position for machining. Communication with the new chuck is based on wireless technology (Bluetooth). Chuck integrated piezoactuators position the workpiece in 4 DOF. Among those, 2 DOF are used for a compensation of the eccentricity and the remaining 2 DOF correct the inclination. Thus, a complete alignment of the workpiece to the axis of rotation is accomplished.
