Abstract
The use of Electrical Discharge Machining (EDM) for the manufacturing of moulds and
dies is generally accomplished by using different cutting regimens, from roughing to finishing, until
the specified surface finish and dimensional tolerances are met. Multistage planetary EDM can be
used to simplify the production process. Benefits such as the reduction of machining time, the need
for less electrodes, electrode wear minimization and the improvement of the final surface finish of
the component can be obtained. Design of multistage planetary EDM strategies requires a sound
knowledge of the optimum radius for each orbit that assures surface roughness and dimensional
accuracy together with a minimum machining time. Therefore, it is necessary to know the “exact”
value of the gap at each stage. In this paper the influence of different process variables on the design
of multistage planetary EDM strategies is analyzed.
