2.3.4.1 Setting Workpiece Coordinate
System Offset Data
(1) Enter the number corresponding to the workpiece coordinate system in # ( ), put offset data in DATA
( ), then press the [INPUT] key. This defines workpiece coordinate system offset data.
(2) The workpiece coordinate system offset data thus defined is then displayed at the position of the
workpiece coordinate system and the number in # ( ) changes to the next setting number and the
data in DATA ( ) disappears.
(3) The number displayed in # ( ) is incremented and decremented by one when pressing the arrow
keys [↑] [↓]
.
(4) Typing "I" in # ( ) and pressing the [INPUT] key puts the setting mode to the incremental mode. Data
set in the incremental mode is added to the displayed data.
Typing "A" in # ( ) and pressing the [INPUT] key cancels the incremental mode and restores the
absolute mode.
2.3.4.2 Setting External Workpiece Co
ordinate Sy
stem Offset Data
By measuring the coordinate system deviation with an external touch sensor, etc., all workpiece coordinate
systems G54 to G59 can be offset.
External workpiece coordinate system data can be defined in one of two ways: inputting external data
directly to the external offset (EXT) or entering it into the setting field on the screen (EXT).
The setting method is the same as for workpiece coordinate system offset data.
2.3.4.3 Displaying Machine Position Data
As with the
POSITION screen, data of each axis displayed at the [MACHINE] on the WORK OFFSET
screen indicates the current machine position in reference to the zero point on the basic machine
coordinate system; it cannot be changed on this screen.
