ABSTRACT:
The speed at which the electrode on a spark erosion machine approaches the workpiece is controlled in accordance with the continuously measured force on the electrode due to the pressure of the dielectric. This force may be measured by a pre-stressed spring in the traction rod of the electrode carrier or by extension strain measuring strips on said traction rod. Apparatus to which the process is particularly suitable is described.
