- Behavior of smoothing with G64x

Description:
Configuration of smoothing with G641 and G642 or G643.
The MD is decimal-coded. The units digits define the response with G643, and the tens
digits the response 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 digits are used to configure smoothing with
G644.

geometry axes. The axis-specific tolerances in MD33100 $MA_COMPRESS_POS_TOL are used
for smoothing all other axes.
x2:
orientation movement. The axis-specific tolerances in MD33100 $MA_COMPRESS_POS_TOL are
used for all other axes.
x3:
tolerances SD42465 $SC_SMOOTH_CONTUR_TOL and SD42466 $SC_SMOOTH_ORI_TOL. All other
axes are smoothed with an axis-specific tolerance.

tolerances is ignored.

SD42466 $SC_SMOOTH_ORI_TOL. The axis-specific tolerances in MD33100
$MA_COMPRESS_POS_TOL are used for smoothing all other axes.

SD42465 $SC_SMOOTH_CONTUR_TOL and SD42466 $SC_SMOOTH_ORI_TOL. Other axes are smoothed

tolerances is ignored.
Possible values of the hundreds digit (specification of path velocity for smoothing):

from the specified maximum values for acceleration and jerk of the axes or path
involved. This can lead to an increase in
of the axes involved.
1xx:
G641. Only a constant limit velocity is specified. In the case of smoothing with G641/
G642, this prevents the axes involved accelerating in the

ranges.
