6.13 SMOOTH INTERPOLATION
M
Overview
Either of two types of machining can be selected, depending on the
program command.
- For those portions where the accuracy of the figure is critical,
such as at corners, machining is performed exactly as specified
by the program command.
- For those portions having a large radius of curvature where a
smooth figure must be created, points along the machining path
are interpolated with a smooth curve, and calculated from the
polygonal lines specified with the program command (smooth
interpolation).
The above operations implement high-speed high-precision
machining.
Parameter
8486
Maximum travel distance of a block where smooth interpolation or Nano
smoothing is applied
[Input type] Setting input
[Data type] Real path
[Unit of data] mm, inch (input unit)
[Minimum unit of data] Depend on the increment system of the reference axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting
table (A) )
(When the increment system is IS-B, -999999.999 to +999999.999)
This parameter specifies a block length used as a reference to decide
whether to apply smooth interpolation or Nano smoothing. If the line
specified in a block is longer than the value set in the parameter,
smooth interpolation will not be applied to that block.

error.
