INTERPOLATION FUNCTIONS

Interpolation functions specify the way to make an axis movement (in
other words, a movement of the tool with respect to the workpiece or
table).

4.1

POSITIONING (G00)

The G00 command moves a tool to the position in the workpiece
system specified with an absolute or an incremental programming at a
rapid traverse rate.
In the absolute programming, coordinate value of the end point is
programmed.
In the incremental programming the distance the tool moves is
programmed.

Format

G00

IP_

;

IP_ :

For an absolute programming, the coordinates of an
end point, and for an incremental programming, the
distance the tool moves.

Explanation

Either of the following tool paths can be selected according to bit 1
(LRP) of parameter No. 1401.

•

Nonlinear interpolation type positioning

The tool is positioned with the rapid traverse rate for each axis
separately. The tool path is normally straight.

•

Linear interpolation type positioning

The tool is positioned within the shortest possible time at a speed
that is not more than the rapid traverse rate for each axis.

End position

Non linear interpolation type positioning

Start position

Linear interpolation type positioning

The rapid traverse rate in G00 command is set to the parameter No.
1420 for each axis independently by the machine tool builder. In the
positioning mode actuated by G00, the tool is accelerated to a
predetermined speed at the start of a block and is decelerated at the
end of a block. Execution proceeds to the next block after confirming
the in-position.
"In-position " means that the feed motor is within the specified range.
This range is determined by the machine tool builder by setting to
parameter (No. 1826).
