15. COMPENSATION FUNCTION
A mirror image of a programmed command can be produced with respect
to a programmed axis of symmetry (Fig. 15.12 (a)).
(1) Original image of a programmed command
Axis of symmetry (X=50)
Axis of symmetry
(2) Image symmetrical about a line parallel to the Y–axis and crossing
the X–axis at 50
(3) Image symmetrical about point (50, 50)
(4) Image symmetrical about a line parallel to the X–axis and crossing
the Y–axis at 50
