3. INTERPOLATION FUNCTIONS
NC FUNCTION
23
Positioning is done with each axis separately (Non linear interpolation
type positioning).
Either of the following tool paths can be selected accroding to bit 1 of
parameter No. 1401.
D Non linear interpolation positioning
The tool is positioned with the rapid traverse rate for each axis
separately. When an absolute command is used, the tool moves at the
rapid traverse rate to a specified point in the workpiece coordinate
system. When an incremental command is used, the tool moves a
specified distance at the rapid traverse rate from the current position.
The tool path is normally straight.
D Linear interpolation posioning
The tool path is the same as in linear interpolation (G01). The tool is
positioned within the shortest possible time at a speed that is not more
than the rapid traverse rate for each axis.

It is decelerated, to a stop at the end point, and imposition check is
performed (checks whether the machine has come to the specified
position). The in–position check can be suppressed using a parameter.
Width of imposition can be set as a parameter.
