Subprograms can be called from a main program, and also from another subprogram. In
total, up to eight program levels, including the main program, are available for this type of
nested call.

Additional Information Part 2
In addition to the common specification in Cartesian coordinates (X, Y, Z), the points of a
workpiece can also be specified using polar coordinates.
Polar coordinates are also helpful if a workpiece or a part of it is dimensioned from a
Subprogram
central point (pole) with specification of the radius and the angle.
The polar coordinates refer to the plane activated with G17 to G19. In addition, the third
L10
axis perpendicular to this plane can be specified. When doing so, spatial specifications
N10 R1=34...
can be programmed as cylindrical coordinates.
N20 X...Z....
The polar radius RP= specifies the distance of the point to the pole. It is saved and must
only be written in blocks in which it changes, after the pole or the plane has been
...
changed.
...
The polar angle AP= is always referred to the horizontal axis (abscissa) of the plane (for
M17 example, with G17: X axis). Positive or negative angle
positive angle is defined as follows:
Starting from the plus direction of X axis and rotates CCW.
It is saved and must only be written in blocks in which it changes, after the pole or the
plane has been changed.
