2.1.8.2 Working area limitation in BKS
Application
Using the "working area limitation in BKS", the working area of a machine tool is limited so
that the surrounding devices (e.g., tool revolver, measuring stations) are protected against
damage.
Working area limits
The lower and upper working area limits of each axes are adjusted through setting data or
programmed through part program instructions:
Working area limitation through setting data
The adjustments are done through the immediately effective axis-specific setting data:
SD43420 $SA_WORKAREA_LIMIT_PLUS (Working area limitation plus)
SD43430 $SA_WORKAREA_LIMIT_MINUS (Working area limitation minus)
Programmed working area limitation
The programming is done using the G commands:
G25 X… Y… Z…
lower working area limitation
G26 X… Y… Z…
upper working area limitation
