# Selecting Akima spline interpolation (#SPLINE ON)

## Release Note

As of Build V2.11.2010.02 the command #SPLINE ON replaces the command #SET SPLINE ON. For compatibility reasons, this command is still available but it recommended not to use it in new NC programs.

Syntax:
#SPLINE ON

Akima spline interpolation is selected in the last mode selected. The Akima spline curve starts at the last target point programmed. This point is the first vertex of the Akima spline curve.

The command may be programmed in the same statement as the second vertex or in the preceding statement.

Alternatively, Akima spline interpolation can be selected using the G151 command.
