6. Interpolation Functions
(7) When the radius is commanded with the absolute value, command the distance from the zero
point in the workpiece coordinate system (note that the local coordinate system is applied
when the local coordinate system is set).
(8) When the radius is commanded with the incremental value command, considering the end
point of the previous block as the polar coordinate center, command the incremental value
from that end point. The angle is commanded with the incremental value of the angle from the
previous block.
(9) When the radius is commanded with the negative value, the same operation as the command
that the radius command value is changed to the absolute value and 180° is added to the
angle command value.
Command position
(1) When the zero point in the workpiece coordinate system is applied to the polar
coordinate center
The zero point in the workpiece coordinate system is applied to the polar coordinate center by
commanding the radius with the absolute value. Note that the zero point in the local coordinate
system is applied to the polar coordinate center if the local coordinate system (G52) is used.
Radius
When the angle is the absolute
value command
Command position when the zero point in the workpiece coordinate system is applied to
the polar coordinate center
(2) When the present position is applied to the polar coordinate center
The present position is applied to the polar coordinate center by commanding the radius with
the incremental value.
When the angle is the absolute
value command
