13.AXIS CONTROL OPERATION B-63324EN-1/03
- 586 -
Limitation
The direction of movement during manual operation, the direction of
movement from an intermediate point to the reference position during
automatic reference position return (G28), the direction of approach
during unidirectional positioning (G60), and the shift direction in a
boring cycle (G76, G87) cannot be reserved.
NOTE
1 The machine coordinate and absolute coordinate are
updated in different directions along the specified
axis. The workpiece coordinate system shifts as the
machine moves. When the mirror image function is
enabled for the X-axis, the coordinate system shifts
as shown in fig 13.2 ( c ).After a desired machining
has been finished, move the machine to the
position where the mirror image function was
applied and disable the function. This cancels the
shift of the workpiece coordinate system to zero.
Alternatively, perform one of the following to set the
shift of the workpiece coordinate system to zero.
-Manual reference position return
-Presetting the workpiece coordinate system(by
using the G92.1 command or by specifying the
preset operation on the MDI)
2 The mirror image cannot be switched during axis
movement. Always switch the mirror image during
stopped state.
3 For mirror image during manual operation, either on
or off of mirror image that was valid by setting
operation or by external mirror image signal when
the mode was switched to the manual operation is
effective. Switching of mirror image state either by
setting operation or by external mirror image signal
is not effective in the manual operation.
