Parameters
Direction of The tool travels in the programmed direction from the circle starting point to its end
rotation point. You can program this direction as clockwise (right) or counterclockwise (left).
α
Polar angle (abs. or inc., positive or negative)
3-228
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 current position on a circular path to the
programmed end point (angle) at the machining feedrate.
The radius corresponds to the distance from the current tool position
to the defined pole, i.e. the circle start and end point positions are at
the same distance from the defined pole.
The 1st circle in polar coordinates entered after the pole must be
programmed with an absolute angle. You can program any further
lines or circles with incremental coordinates.
Press the "Straight/Circle", "Polar" and "Circle polar" softkeys.
