Application: For full-surface machining, you describe the complete
contour, machine the front face, rechuck the workpiece using an
expert program, and then machine the rear face. To enable you to
program rear-face machining in the same way as front-face machining
(Z-axis orientation, arc rotational direction, etc.). Includes the expert
program commands for converting and mirroring.
Spindle with workpiece G98
The assignment of the spindle is required for thread-cutting, drilling,
and milling cycles if the workpiece is not in the main spindle.
„ Mirror the traverse paths and tool lengths in separate
G30 commands.
„ Q1, Q2 without axis selection switches the mirroring
function off.
„ Only configured axes can be selected.
Danger of collision!
„ In the transition from AUTOMATIC to MANUAL
OPERATION, conversions and mirror images are
retained.
„ Switch off the conversion/mirroring if you activate the
front-face machining after rear-face machining (for
example during program section repeats with M99).
„ After a new program selection, the conversion/mirroring
is switched off (example: transition from MANUAL to
AUTOMATIC mode).
Parameters
Q Spindle number (0 to 3); (default: 0 = main spindle)
