A straight line in the polar coordinate system is defined by a radius (L)
and an angle (α). The angle refers to the X axis.
The tool moves from its current position on a straight line to the
programmed end point at the machining feedrate or in rapid traverse.
The 1st line 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 "Straight polar" softkeys.
