Workpiece main directory (_N_WKS_DIR)
The workpiece main directory exists in the standard setup of the program memory under the
name _N_WKS_DIR. The workpiece main directory contains all the workpiece directories for
the workpieces that you have programmed.
Workpiece directories (..._WPD)
A workpiece directory contains all files required for machining a workpiece. These can be main
programs, subprograms, any initialization programs and comment files.
The first time a part program is started, initialization programs are executed once, depending
on the selected program (in accordance with machine data MD11280 $MN_WPD_INI_MODE).
Example:
The workpiece directory _N_SHAFT_WPD, created for SHAFT workpiece contains the
following files:
File Description
