4.11.1 Figure copy (G72.1, G72.2)
Does not work with SINUMERIK 802D sl.
Using the figure copy function, a once programmed contour can be easily repeated
or, respectivly, copied. A linear (G72.2) or rotational (G72.1) copy can be carried
out by means of this function.
Format
G72.1 X... Y... (Z...) P... L... R...
X, Y, Z:
P:
L:
R:
Through G72.1, a sub--program containing the contour to be copied can be called
repeatedly. Prior to calling each sub--program, the coordinate system is rotated by
a certain angle. The coordinate rotation is carried out along the axis perpendicular
to the selected plane.
G72.2 I... J... K... P... L...
I, J, K:
P:
L:
Through G72.2, a sub--program, in which the contour to be repeated is program-
med, is repeatedly called. Prior to each sub--program call, the axes programmed
through I, J, K are traversed incrementally. The cycle calls the sub--program by the
number of times specified by address L. Prior to each sub--program call, a path
programmed in I, J, K and calculated from the initial point is traversed incremen-
tally.
