1.9 Orientation
Compression mode
The manner in which the tolerances are to be considered is set via the unit position in the
machine data:
MD20482 $MC_COMPRESSOR_MODE (mode of compression)
Value
0
1
2
3
With the tens digit of MD20482 you set whether blocks with programmed tool orientation and/
or value assignments (for example, X=100 ...) are to be compressed or not:
Value
x0x
x1x
x2x
x3x

Meaning
The tolerances specified with MD33100 $MA_COMPRESS_POS_TOL are observed for all
the axes (geo and orientation axes).
The contour tolerance specified with SD42475 $SC_COMPRESS_CONTUR_TOL is
effective for the geometry axes.
The axis-specific tolerances MD33100 $MA_COMPRESS_POS_TOL are effective for the
orientation axes.
The axis-specific tolerances MD33100 $MA_COMPRESS_POS_TOL are effective for the
geometry axes.
The maximum angular deviations SD42476 $SC_COMPRESS_ORI_TOL or
SD42477 $SC_COMPRESS_ORI_ROT_TOL are effective for the orientation axes.
The contour tolerance specified with SD42475 $SC_COMPRESS_CONTUR_TOL is
effective for the geometry axes.
The maximum angular deviations SD42476 $SC_COMPRESS_ORI_TOL or
SD42477 $SC_COMPRESS_ORI_ROT_TOL are effective for the orientation axes.
Meaning
All blocks with programmed tool orientation and/or value assignments will be compressed
(default setting).
Notice: This behavior is incompatible with earlier SW versions!
Only the blocks with programmed tool orientation will be compressed. The blocks with
value assignments will not be compressed.
Only the blocks with value assignments will be compressed. The blocks with programmed
tool orientation will not be compressed.
All blocks with programmed tool orientation and/or value assignments will not be
compressed.
This setting provides a behavior that is fully compatible with earlier SW versions.
