1. G Function Description
1.2.23 G51.1/G50.1: PROGRAMMABLE MIRROR
IMAGE
Command form:
G51.1 X___Y___Z___;
G50.1;//programmable mirror image cancel
X, Y, Z: mirror point (axis) coordinate value.
Description:
when cut symmetry shape, we only need one program between left side
or right side, and use this function we can process another side. G51.1
specify point(position) and axis of symmetry for producing a mirror image
if there is only one axis specify mirror image on specified plane,
circular、tool length compensation or the direction of coordinate rotation or
direction of compensation, all of those execute reverse.
because of this function use in part coordinates, when counter reset or
work coordinates change, center of mirror image is changed.
G28, G30 in programmable mirror image, before the mid-point ,
programmable mirror image is effective, after the mid-point, programmable
mirror image is not execute.
execute G29 in programmable mirror image, that is effective to mirror
image of mid-point.
Note:
Execute mirror image cancel out of the center point, absolute value can
not match with mechanical position, as the below PIC (this status continues
until executing G90、G28 or G30). If you specify the center of mirror image
again in the absolute static status, it will be specified to a unable expect
position. Please use absolute positioning after mirror image cancel.
