Offset Tables and Setup

Chapter 3

Diameter or Radius {RADI/DIAM}

If the offset value being changed has been selected in AMP as the
diameter axis (typically the axis perpendicular to the spindle center
line), data may be entered into the offset table as either a radius or
diameter value. The current mode for this axis is displayed with an R
for radius or a D for diameter mode next to that axes offset. Pressing
the

{RADI/ DIAM}

softkey toggles the offset between these two

modes.

This softkey does not change the current mode of control operation
(as selected with G07 or G08); it only alters how data is entered into
the table. For details on radius or diameter mode, refer to chapter 13
(G07/G08).

OFFSET

Enter offset data; replace or add data as follows:

Press this softkey:

Then:

{REPLCE VALUE}

Type in the new value. Press the [ENTER] key. The new

value replaces the old value for that feedrate.

{ADD TO VALUE

}

Type in the number. Press the [ENTER] key. The new value

is added to the old value for that area.

If desired, stored offset data can be copied from one axis to another
axis for all offset numbers (rather than having to change each axis
individually).

A. Press the

{COPY OFFSET}

softkey.

B. “COPY (SOURCE, DESTINATION):” appears. Enter the axis

letter from which the data is coming, then a comma, and then
enter the axis letter to which the data is going. For example,

COPY (SOURCE, DESTINATION): X,Z

copies the offset data from the X axis to the Z axis for all offset
numbers.
