In this case, the associated matrix _MATRIX is:
B0$75,;
A change from
G17
to
G18
or
G19
does not alter the result, because the assignment of the
length components to the geometry axes changes in the same way as the assignment of the
abscissa, ordinate and applicate.
A frame rotation of Z through 60 degrees is now programmed with
G17
active, e.g.,
rot
Z60
. The direction of the applicate (Z direction) remains unchanged; the main component of
L2
now lies in the direction of the new X axis; the main component of
L1
now lies in the
direction of the negative Y axis. The return axis is thus 1, and _AXIND contains the values
(2, -3, 1).
In this case, the associated matrix _MATRIX is:
B0$75,;
