Description: The SD is active for thread cutting with G33 (G34, G35).
It has three elements that define the behavior of the thread axis during runup (1st
element), during deceleration/smoothing
"G33(G34, G35) on G00/G01" (2nd element), and
during smoothing between 2 thread blocks (3rd element).
The first two values have the same properties for thread run-in and thread run-out:
<0:
The thread axis is started/decelerated with configured acceleration. Jerk is according
to the current programming of BRISK/SOFT. Behavior is compatible with MD
20650__THREAD_START_IS_HARD = FALSE used until now.
0:
Starting/deceleration of the feed axis during thread cutting is stepped. Behavior is
compatible with MD 20650__THREAD_START_IS_HARD = TRUE used until now.
>0:
The maximum thread starting or deceleration path is specified. The specified distance
can lead to acceleration overload of the axis. The SD is written from the block when
DITR
(displacement
thread
ramp) is programmed. An excessively long path has no effect.
Note:
MD 10710 $MN_PROG_SD_RESET_SAVE_TAB can be set so that the value written by the part
program is transferred to the active file system on reset (that is the value is
retained after reset.)
The 3rd value enables smoothing at a corner between 2 thread blocks in order to soften
the transition. There is no rounding by smoothing if the dynamic response of the
machine allows a hard transition on account of MD32210 $MA_MAX_ACCEL_OVL_FACTOR:
-1:
The transition is made as geometrically soft as possible.
0:
The corner is left with hard retraction, the axes follow the specification of the
control loops.
> 0:
Reserved for an expansion of the function.
