Description
Workpiece directory, _N_WKS_DIR
The workpiece directory exists in the standard setup of the program directory under the
name _N_WKS_DIR. The workpiece directory contains all the workpiece directories for the
workpieces that you have programmed.
Workpiece directories, identification WPD
To make data and program handling more flexible certain data and programs can be
grouped together or stored in individual workpiece directories.
A workpiece directory contains all files required for machining a workpiece. These can be
main programs, subroutines, any initialization programs and comment files.
Initialization programs are executed once as specified in the machine data
MD 11280: WPD_INI_MODE after the program selection with the first parts program start.
Example: The workpiece directory _N_SHAFT_WPD, created for workpiece SHAFT contains
the following files:
_N_SHAFT_MPF
_N_PART2_MPF
_N_PART1_SPF
_N_PART2_SPF
_N_SHAFT_INI
_N_SHAFT_SEA
_N_PART2_INI
