Smoothing with greatest possible dynamic response in G644
Smoothing with maximum possible dynamic response is configured in the thousands place with
MD20480 $MC_SMOOTHING_MODE.
Value Meaning
0 Specification of maximum axial deviations with:
MD33100 $MA_COMPRESS_POS_TOL
1 Specification of maximum smoothing path by programming:
ADIS=... or ADISPOS=...
2 Specification of the maximum possible frequencies of each axis occurring in the smoothing
range with:
MD32440 $MA_LOOKAH_FREQUENCY
The smoothing range is defined such that no frequencies in excess of the specified maximum
can occur during smoothing motion.
3 When smoothing with G644, neither the tolerance nor the smoothing clearance is monitored.
Each axis traverses around a corner with the maximum possible dynamic response.
With SOFT, both the maximum acceleration and the maximum jerk of each axis is maintained.
With the BRISK command, the jerk is not limited; instead, each axis travels at the maximum
possible acceleration.
Smoothing of tangential block transitions with G645
With G645, the smoothing motion is defined so that the acceleration of all axes involved
remains smooth (no jumps) and the parameterized maximum deviations from the original
contour (MD33120 $MA_PATH_TRANS_POS_TOL) are not exceeded.
In the case of angular non-tangential block transitions, the smoothing behavior is the same as
with G642.
