Further information
Reference point at the tool
When tool length offset is active, the tip of the tool is monitored as reference point, otherwise
it is the toolholder reference point.
Taking into consideration the tool radius must be activated separately. This is done using
channel-specific machine data:

Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Using the working area
limitation G25/26, the working area of a
lathe is limited so that the surrounding
devices and equipment - such as revolv‐
er, measuring station, etc. are protected
against damage.
Default setting: WALIMON
