Siemens SINUMERIK 828D Commissioning Manual page 439

Requirements
● The machine has several clamping options available for selection.
● The machine has a clamping option that does not point in the Z direction as standard (e.g.
a boring mill).
Under the following circumstances, you can specify the position and orientation of the rotary
axes in the machine data MD53220 and MD52207:
● The position and orientation of the rotary axis is offset against the MCS zero point, but not
specified by a tool holder or a TRAORI.
● In a turning machine, the reference points of the main spindle or counterspindle are offset
against the MCS zero point in X or Z.
● The counterspindle cannot be traversed with a saddle, but rather is at a fixed position.
In order that for simulation / simultaneous recording, the rotary axes are displayed at the correct
location, their positions in the machine coordinate system must be specified using the following
machine data:
MD53220 $MAS_AXIS_MCS_POSITION[n]
For further information about the transformation of a rotary axis, see Chapter"Configuring
cycles (Page 75)".
Function
Set the following channel-specific machine data:
MD52207 $MCS_USAGE_ATTRIB[n]
Bit 0
Bit 1
Bit 2
Bit 8
MD52214 $MCS_FUNCTION_MASK_MILL
Bit 1
Take the machine configuration for MD20080 from the example.
