Circle polar
A circle in the polar coordinate system is defined by an angle (α). The angle refers to the X
axis.
The tool moves from its actual position on a circular path to the programmed end point (angle)
at the machining feedrate. The radius corresponds to the distance from the actual tool position
to the defined pole, i.e. the circle starting and end point positions are at the same distance
from the defined pole.
The 1st arc in polar coordinates entered after the pole must be programmed with an absolute
angle. You can program any additional straight lines or circles with incremental coordinates.
