G50.1 X__ Y__ Z__; Specify corresponding axis to cancel the mirror image of axes
G50.1,G51.1are G codes of No.22, which are modal G codes.
Command function：Specify mirror image function for axes.
G51.1 X__ Y__ Z__：Specify mirror image function for axes. （put on the axis as a mirror）. Thereinto,
X__ Y__ Z__is an absolute command.
G50.1 X__ Y__ Z__：Cancel mirror image function for axes. If the address of the axis is not specified,
which indicates no mirror image function is cancelled.
Explanations:
1. Some commands are interchanged when a mirror image to the plane is specified.
z G02/G03 of circular commands are interchanged.
z G41/G42 of cutter compensation commands are interchanged.
z CW and CCW（directions of rotation）are interchanged.
2. This function is not effective for 4
th
and 5
th
axes.
3．In canned cycle, the depth of Z are not proceeded with the mirror image.
Limitations
z In programmable mirror image, G codes related to reference return（G27/G28/G29/G30, etc.）and those
for changing the coordinate system（G52~G59,G92, etc）can not be specified. If any of these G codes
is necessary, specify it only after canceling the programmable mirror image mode.
z Processing proceeds from program mirror image to scaling and coordinate rotation. The commands
should be specified in order, for cancellation, in the reverse order. G50.1 and G51.1 can not be
specified in scaling and rotation mode.
Modal display of scaling
According to G51.1 X__ Y__ Z__, specified mirror image of
these blocks are generated from specified symmetry axis
