G102/G103 Polar coordinates: circular interpolation

The preparatory function G102/G103 corresponds in function to the
preparatory function G02/G03 during the programming of the circle with
center coordinates in the rectangular coordinate system.

G102 AXES W F E L
G103 AXES W F E L

AXES

Center coordinates

W

Polar angle

F

Path speed

E, L

Selection of feed speed via speed (E) and increment (L). F=E*L.

The center of the polar coordinate system is defined by two addresses: X/Y
for G17, X/Z for G18, Y/Z for G19. The assignment of the principal axes can
be changed with G16. When the axes U and W are used as main axes, these
cannot be used for the center programming.

The center coordinates can be programmed in absolute dimensions or in
incremental dimensions. The center of the polar coordinate system also
determines the center of the circle at the same time, therefore programming
the circle radius is not necessary.

The target position is defined by the polar angle W in reference to the current
center. The angle can be programmed in absolute dimensions or in
incremental dimensions.

The programmed center coordinates have a modal effect.

The preparatory function G102/G103 has a modal effect.
