6. INTERPOLATION FUNCTION
B–63173EN–1/01
238
The G00 command moves a tool to the position in the workpiece system
specified with an absolute or an incremental command at a rapid traverse
rate.
In the absolute command, coordinate value of the end point is
programmed.
In the incremental command the distance the tool moves is programmed.
The tool path is determined by selecting one of the following with
parameter LRP (No. 1401#1):
D Linear interpolation type positioning
The tool path for positioning is determined in the same manner as
linear interpolation (G01). The tool moves at an appropriate speed so
that positioning can be performed in the shortest time without the
speed exceeding the rapid traverse rate for each axis.
D Non–linear interpolation type positioning
Positioning is performed with each axis independently at the rapid
traverse rate. Generally, the tool path is not a straight line.
The rapid traverse rate in the 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.

LRP Positioning (G00)
0 : Positioning is performed with non–linear type positioning so that the
tool moves along each axis independently at rapid traverse.
1 : Positioning is performed with linear interpolation so that the tool
moves in a straight line.
