Coordinate Control
Chapter 11
11-46
Usually workpieces on cylindrical grinders are cylindrical in shape. The
control allows programming of workpiece dimensions as radius or
diameter values. It also allows data to be entered into the offset tables as
either radius or diameter values.
This feature is only available on cylindrical grinder configurations.
G08 places the control in diameter programming mode. This mode
remains active until canceled by a G07.
G07 places the control in radius programming mode. This mode remains
active until canceled by a G08.
Your system installer can select G08 or G07 in AMP to be the active mode
at power-up. You can display the currently active G code by selecting the
status screen.
