MIRROR IMAGE (Cycle 8)
Function
The TNC can machine the mirror image of a contour in the working
plane.
Input
Enter the axis that you wish to mirror.
The tool axis cannot be mirrored.
Cancellation
The cycle is canceled by replying with NO ENT to the dialog question.
Effect
The mirror image cycle becomes effective as soon as it is defined in
the program. The mirrored axis is indicated in the status display with
the index S by the mirrored axes.
„ When one axis is mirrored, the machining direction of the electrode
is reversed.
„ If two axes are mirrored, the machining direction remains the same.
The mirror image depends on the location of the datum:
„ If the datum lies on the contour to be mirrored:
The part simply ”flips over” (see top illustration).
„ If the datum lies outside the contour to be mirrored:
The part also ”jumps” to another location (see bottom illustration).
