2.3 Channel-specific machine data
Description: Configuration of smoothing with G641 and G642 or G643.
The MD is decimal-coded. The units digits define the behavior with G643, and
the tens digits the behavior with G642. The hundreds digit can define
whether, with G641 or G642, the axes may be accelerated within the smoothing
range or traversed at constant velocity. The thousands and ten-thousands dig-
its are used to configure smoothing with G644.
x0: G643 uses axis-specific tolerances; these are set with the axis-specific
MD33100 $MA_COMPRESS_POS_TOL.
x1: G643 uses the contour tolerance SD42465 $SC_SMOOTH_CONTUR_TOL for
smoothing the geometry axes. The axis-specific tolerances in MD33100
$MA_COMPRESS_POS_TOL are used for smoothing all other axes.
x2: The angular tolerance SD42466 $SC_SMOOTH_ORI_TOL is used for smoothing
the orientation movement. The axis-specific tolerances in MD33100
$MA_COMPRESS_POS_TOL are used for all other axes.
x3: Combination of the two options 01 and 02. This means that G643 uses the
tolerances SD42465 $SC_SMOOTH_CONTUR_TOL and SD42466 $SC_SMOOTH_ORI_TOL. All
other axes are smoothed with an axis-specific tolerance.
x4: G643 uses the smoothing length programmed with ADIS= or ADISPOS=. The
specification of possible axis-specific tolerances or contour and orientation
tolerances is ignored.
0x: G642 uses axis-specific tolerances; these are set with the axis-specific
MD33100 $MA_COMPRESS_POS_TOL.
1x: G642 uses the contour tolerance for smoothing the geometry axes. The
axis-specific tolerances in MD33100 $MA_COMPRESS_POS_TOL are used for smooth-
ing all other axes.
2x: The orientation movement with G642 is smoothed using the angular toler-
ance SD42466 $SC_SMOOTH_ORI_TOL. The axis-specific tolerances in MD33100
$MA_COMPRESS_POS_TOL are used for smoothing all other axes.
3x: Combination of both options 10 and 20. This means that G642 uses the
tolerances SD42465 $SC_SMOOTH_CONTUR_TOL und SD42466 $SC_SMOOTH_ORI_TOL.
Other axes are smoothed with an axis-specific tolerance.
4x: G642 uses the smoothing length programmed with ADIS= or ADISPOS=. The
specification of possible axis-specific tolerances or contour and orientation
tolerances is ignored.
Possible values of the hundreds digit (specification of path velocity for
smoothing):
0xx: A profile of the limit velocity is calculated within the smoothing
range from the specified maximum values for acceleration and jerk of the axes
or path involved. This can lead to an increase in
path velocity in the smoothing range and consequently to an
acceleration of the axes involved.
1xx: A profile of the limit velocity is not calculated for smoothing
blocks with G641. Only a constant limit velocity is specified. In the case of
smoothing with G641/G642, this prevents the axes involved accelerating in the
smoothing range. However, this setting may lead to smoothing
blocks being traversed at a velocity that is too low, especially in the case
of long smoothing ranges.
2xx: No velocity profile for G642 and G645 (see the above scenario for
description).
