- 701 -
Nanointerpolation is performed for the curve inferred from the
corrected insertion points, so the resultant cutting surface becomes
smooth.

- Specifying the tolerance
The tolerance of the program of nano smoothing is specified in
parameter No. 19581.
The insertion points are corrected within tolerance, and a curve is
inferred accordingly.
If 0 is specified in parameter No. 19581, the minimum travel distance
in the increment system is considered to be the tolerance.
- Making a decision on the basis of the spacing between adjacent programmed
points
If the spacing between adjacent programmed points (block length)
exceeds the value specified in parameter No. 8486 or falls below the
value specified in parameter No. 8490 in the nano smoothing mode,
the nano smoothing mode is cancelled at the start point of the block.
Linear interpolation can be performed in the block.
If the values specified in the parameters are 0, no decision is made on
the basis of the spacing between adjacent programmed points.
- Making a decision at a corner
If the difference in angle between adjacent programmed blocks
exceeds the value specified in parameter No. 8487 in the nano
smoothing mode, the nano smoothing mode is cancelled at the corner.
