3.1 POSITIONING (G00)
Explanation
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.
Either of the following tool paths can be selected according to
parameter.
- Nonlinear interpolation positioning
The tool is positioned with the rapid traverse rate for each axis
separately. The tool path is normally straight.
- Linear interpolation positioning
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.
Fig.3.1 (a) Tool path
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.
In-position check for each block can be disabled by setting parameter
accordingly.
