Tool and mould-making is a key factor in industrial manufacturing. In addition to machining processes, spark erosion is also used, the electrodes of which are very complex to manufacture. Researchers are now developing a simpler method for this. In Germany, tool and mould-making is one of the most important branches of the industry. In order to remain internationally competitive, German tool and die-makers are striving to overcome the manufactory-like individual production and achieve industrial efficiency and excellence. Successful toolmakers, therefore, strive for innovative tool concepts. Even if several geometries can be combined on one electrode, sometimes a number of 100 ≤ n ≤ 1000 geometric-specific sink electrodes are required, which are manufactured and successively spark-eroded in order to obtain the final contour of an injection mould. This results in the disadvantage that the manufacture and replacement of the sink electrodes often account for a much larger proportion of the total production time than the actual sink erosion process. In order to reduce the electrode production time (tF) and the machine set-up time (tR) as well as realise the possibility of internal f...
