6.15 SMOOTH INTERPOLATION
General
Either of two types of machining can be selected, depending on the
program command.
1) 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.
2) 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, calculated from the
polygonal lines specified with the program command (smooth
interpolation).
Parameter
7672 Maximum travel of a block executed with smooth interpolation
[Input type] Setting input
[Data type] Real
[Unit of data] mm, inch (input unit)
[Minimum unit of data] Depends on the increment system of the reference axis.
[Valid data range] Nine digits of the least input increment (see Standard Parameter Setting
Table (A).)
(For IS-B, -999999.999 to +999999.999)
Set the length specified in each block that is to be checked as a condition for
performing smooth interpolation. When the length specified in a block is longer
than this setting, the block is executed without smooth interpolation.
7673 Angle for which smooth interpolation is not performed
[Input type] Setting input
[Data type] Real
[Unit of data] degree
[Minimum unit of data] Depends on the increment system of the reference axis.
[Valid data range] 0 - 90
Set the angle to be checked as a condition for performing smooth interpolation.
Smooth interpolation is not performed for a point at which the difference in the
angle is greater than this setting.
