Sometimes the user wants to be able to modify feedrates in the NC program itself. This is often desired for production to optimize programs for reduced machining time, part quality, and tool wear. However, editing NC programs manually is normally not recommended unless supported/intended by the used post processor configuration.
The generic Heidenhain post now includes sample code showing how to output feedrate tables using Q-values for each operation which can be easily modified. The feedrate tables are disabled by default but can be enabled by setting the "useFeedQ" property during posting. The same code can be used for any control which supports parameters.
