Explanation
- Mirror image by setting
If the programmable mirror image function is specified when the
command for producing a mirror image is also selected by a CNC
external switch or CNC setting, the programmable mirror image
function is executed first.
Limitation
- Scaling/coordinate system rotation
During coordinate system rotation (G68) or scaling (G51), the
programmable mirror image commands (G50.1, G51.1) must not be
specified.
CAUTION
1 When a mirror image is produced on the other side of
one axis on a specified plane, other commands are
processed as follows:
(1) Circular command: The direction of rotation is
reversed.
(2) Cutter compensation: The direction of offset is
reversed.
(3) Coordinate system rotation: The direction of
rotation is reversed.
2 Relation between move command and machine
travel/coordinate value is as follows in the
programmable mirror image.
3 The first move command coming after G50.1 or
G51.1 must be specified with absolute values.
