Use these 4 basic G-codes to produce axis motion:

G00 Rapid Positioning
G01 Linear interpolation
G02 Circular interpolation (clockwise)
G03 Circular interpolation (counterclockwise)

After the execution of a positioning command the program proceeds to the

next block only after an in-position check function confirms that all

commanded axes have reached the in-position band. Your system installer

sets the in-position band width in AMP. See chapter 18 for details on the

G-codes that you can use to modify the in-position band check.

Format for the rapid positioning mode is:

G00X__

Z__ ;

Where :

Is :

G00

The G00 code establishes the positioning mode. In positioning mode, the cutting

tool is fed along a straight line at the rapid feedrate determined in AMP by your

system installer.

XZ

The end point of the move generated by the G00 block in the current work

coordinate system.

You can perform a rapid positioning in the absolute mode (G90), or the

incremental mode (G91).
