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] Position of the axis in the MCS
[n] 0 = X, 1 = Y, 2 = Z
For further information about the transformation of a rotary axis, see Chapter"Technologies
and cycles (Page 503)".
Function
Set the following channel-specific machine data:
MD52207 $MCS_AXIS_USAGE_ATTRIB[n] Attribute of the axes in the channel
[n] channel axis number
Bit 0 Rotates around 1st Geometry axis (for rotation axes)
Bit 1 Rotates around 2nd Geometry axis (for rotation axes)
Bit 2 Rotates around 3rd Geometry axis (for rotation axes)
Bit 8 Offer rotary axis for blank clamping (on milling machines)
Bit 13 Position of the axis for blank selection from active work offset (with rotary axes)
= 0 When simulation or simultaneous recording are started, the mountable rotary axis is
moved to the position from MD53220.
= 1 With a blank command, The mountable rotary axis is moved into the zero point of the
currently active work offset.
MD52214 $MCS_FUNCTION_MASK_MILL Milling function screen
Bit 1 Offer fixed table for blank clamping (on milling machines)
Take the machine configuration for MD20080 from the example.
