G90 - Absolute Programming (default)
G90 applies to Macro Mode B and establishes a modal setting that tells the control to
interpret all XZ endpoint dimensions in absolute coordinates. G90 Absolute Programming
specifies that all tool endpoint positions are measured from the current part zero position.
Default—Yes
Modal—Yes
Cancels G91 - Incremental Programming (Mode B)
You can use G90 absolute or G91 - Incremental Programming dimensions directly from
the blueprint. Most part programs should begin with a G90 Absolute command that
moves the tool to a fixed position on the machine. Once the start point is defined, you
can study the part blueprint and determine whether to use G90 Absolute or G91
Incremental dimensions.
Most part programs should begin with a G90 command to establish part zero. This setting
remains active until you program G91 to select incremental dimension programming. A
program may switch between G90 Absolute mode and G91 Incremental mode at any
time.
Absolute dimensions are measured from part zero. The figure shows the path that the
tool center will follow.
