Offset Tables and Setup

3-13

Select data entry type:

Unit selection {INCH/METRIC}

To select units of “mm” or “inch” for the offset data, press the
{INCH/METRIC} softkey. The unit selection changes each time you
press the softkey. When you alter the units, the control converts all
existing data to the new unit selection for that offset number.

Diameter or Radius {RADI/DIAM}

If the offset value being changed is for an axis selected in AMP as a
diameter axis, you can enter data into the offset table as either a
radius or diameter value (typically the axis perpendicular to the
headstock center line). Next to the axes offset, the control displays
the current mode for that axis.

If you see:

Then the current mode is:

radius

diameter

Press the {RADI/ DIAM} softkey to toggle the offset between these
two modes.

This feature applies only to the {WHEEL GEOMET} screen for
wheel lengths on cylindrical grinders. If your control is configured
as a surface grinder this softkey is not available (also the R and D do
not appear on the wheel geometry screen).

This feature is not available for surface grinder applications.

Important: This softkey does not change the current mode of control
operation (as selected with G07 or G08), it only alters how data is
entered in the table and displayed. For details on radius or diameter
mode (G07/G08), see page 11-46.
