- Specification of a tolerance
The tolerance of the program which does the Nano Smoothing is set in the parameter
(No.19581). The compensation of the interpolation point is done in the range of the
tolerance. And, the curve profile is presumed.
When the setting value of the parameter is 0, the least increment for the amount of
movement in the increment system is considered to be an a tolerance.
- Judgment by interval of command point
When the interval of the command point (block length) is longer than the setting value
of the parameter (No.8486), or is shorter than the parameter (No.8490), in the Nano
Smoothing mode, Nano Smoothing mode is canceled in the starting point of the block
once. And the block becomes a linear interpolation.
When the setting value of the parameter is 0, it does not judge by the interval of each
command point.
- Judgment of corner part
When the angle difference between the command blocks is larger than the parameter
(No.8487) in the Nano Smoothing mode, the Nano Smoothing mode is canceled in
the corner part once. When the setting value of this parameter is 0, the Judgment of
corner part according to angle difference is not done.
By the way, a very minute block is made by computation error etc. of CAM
By setting the minimum moved distance judged according to the angle difference in
the parameter (No.19582), the judgment of the corner part of this block is disregarded,
and it is connected smoothly
When there is a small movement block compared with this parameter in two
blocks where the corner part is judged, the judgment of corner part is not done.
ngle between command block
However, when the judgment by the interval of the command point is effective by the
parameter (No.8490), the judgment by the interval of the command point gives
priority more than the judgment of the corner part.
Therefore, please set bigger value than the parameter (No.8490) in the parameter
(No.19582).
