Siemens SINUMERIK 840DE SL - 2.2 Dimensional information for transverse axes

Detailed Description
2.2 Dimensional information for transverse axes
Transverse Axes (P1)
2-2 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2.2 2.2 Dimensional information for transverse axes
Transverse axes can be programed with respect to both diameter and radius. Generally,
they are diameter-related, i.e. programmed with doubled path dimension so that the
corresponding dimensional information can be transferred to the part program directly from
the technical drawings.

Switching the diameter programming on/off
The diameter programming is switched on/off with the part program instructions:
• DIAMON: Diameter programming ON
• DIAMOF: Diameter programming OFF, in other words, radius programming ON
• DIAM90: Diameter or radius programming depending on the reference mode:
– Diameter programming ON in connection with absolute dimensioning G90
– Radius programming ON in connection with incremental dimensioning G91
Reference is made exclusively to the transverse axis of the channel.
DIAMON, DIAMOF and DIAM90 belong to G group 29 and are modally operative.
Initial setting
The initial setting is configured with:
MD20150 $MN_GCODE_RESET_VALUES [28] (initial setting of the G groups)
Diameter-related data
After activation of the diameter programming, the following data refer to diameter
dimensions:
