Overview

Task

Electrical Discharge Machining (EDM) is a material removal process for electrically conductive materials. Material removal is based on a process of electrical discharge. Erosion includes wire erosion and die sinking Both types represent a form of spark erosion.

In the die sinking process, the electrode usually has a ‘negative shape’ which must correspond to the material volume to be removed and the ‘positive contour’ to be obtained.

	This function is available as of CNC Build V3.1.3108.5

	This function is an additional option requiring a license.

Effectiveness/possible applications

Die sinking is mainly used for hard materials which would otherwise incur excessive tool costs using mechanical removal methods.

Parameterisation

The CNC must be configured with at least 3 channels in order to use the die sinking technology.

The parameter P-STUP-00033 and specific channel parameters must be configured for each channel.

Programming

For a description of the extensive programming with its many variants, see the section Programming.
