Abstract

The invention relates to a novel method for producing precision parts, especially flat optical data carriers. According to the inventive method, the embossing procedure is program-controlled on the basis of the path function of an electromechanical or hydraulic drive of the driven mold half. When a servomotor is used, the internal path signal thereof can be directly used for calculating the path function or for operating the program control. The novel method allows for a complete speed control of the embossing phase. All factors that can be mechanically influenced from the exterior are detected in more detail for the conditions before and during the embossing phase, thereby allowing for an optimum precision and reproducibility.
