ISO 14649-14:2013 pdf download.Automation systems and integration一Physical device control一Data model for computerized numerical controllers一Part 14:Process data for sink electrical discharge machining (sink-EDM).
This part of Iso 14649 specifies the technology-specific data element needed as process data for sinkEDM. Together with the general process data described in ISO 14649-10, it describes the interface between computerized numerical controller and the programming system (i.e. CAM system or shop- floor programming system) for sink-EDM. It can be used for sink-EDM operations on this kind of machine.
The scope of this part of ISO 14649 does not include tools for any other technologies (e.g. turning, grinding). Tools for these technologies are described in other parts of ISO 14649.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 14649-10 and the following apply.
3.1
roughing
machining operation used to cut a part
Note I to entry: While the aim of roughing is to remove large quantities of material in a short time, the surface quality is usually not important.
Note 2 to entry: The roughing operation is usually followed by the finishing (3.2) operation.
3.2
finishing
machining operation whose aim is to reach the tolerance of the feature required
Note 1 to entry: The finishing operation is usually preceded by the roughing (3.1) operation and followed by the surface finishing (3.3) operation.
3.3
surface finishing
machining operation whose aim is to reach the required surface quality
Note 1 to entry: The surface finishing operation is usually preceded by the finishing (3.3) operation.
4 Process data for sink-EDM
4.1 Header and references
The following listing gives the header and the list of entities which are referenced within this schema.
4.2 Manufacturing features for sink-EDM
4.2.1 General
The sink-EDM features defined in this subclause are the features that are specific for sink-EDM technology, and are not defined in Iso 14649-10. The base class for all sink-EDM features is the machining_feature, defined in ISO 14649-10.
4.2.2 Sink-EDM volumetric pocket
The sink_edm_volumetric_pocket describes a special sink-EDM cavity feature. This feature is created by orbiting the reference point of the tool axis within closed volume. The final shape of the pocket is defined by the outline shape of the tool. The closed volume is defined as a revolved feature, where the feature_boundary curve is revolved around the axis.ISO 14649-14 pdf download.
