Parameters
Q Function is not yet supported.
D Spindle number
X Shift in X (diameter value)
Z Shift in Z
V Mirroring the Z axis of the coordinate system
 Q=0: Do not mirror
 Q=1: Mirror
H Transformation type
 H=0: Contour shift, not mirroring
 H=1: Contour shift, mirroring and reversing the direction
of the contour description
K Shift length of tool: shift coordinate system in Z direction
O Hide elements during transformation
 O=0: All contours are transformed
 O=1: Auxiliary contours are not transformed.
 O=2: Face contours are not transformed
 O=4: Lateral contours are not transformed
You can also add input values in order to combine various
settings (e.g. O=3 Do not transform auxiliary contours or
face contours)
 Program G99 again if the workpiece is transferred to
another spindle and/or moves its position in the working
space.
