Programming a circle with known radius

The tool traverses a circular path with the programmed radius from its actual position to the
programmed circle end point. The control system calculates the circle center point. You do
not need to program interpolation parameters.
The circle can only be traversed at machining feedrate.
Procedure
Milling

Description
The tool travels in the programmed direction from the circle starting point to its end
point. You can program this direction as clockwise or counter-clockwise.
Clockwise direction of rotation
Counter-clockwise direction of rotation
Target position X (abs) or target position X referred to the last programmed
position (inc)
Target position Y (abs) or target position Y referred to the last programmed
position (inc)
Distance between circle starting point and center point in X direction (inc.)
Distance between circle starting point and center point in Y direction (inc.)
Machining feedrate
Plane: The circle is traversed in the set plane with the relevant interpolation
parameters:
XYIJ: XY plane with interpolation parameters I and J
ZXKI: ZX plane with interpolation parameters K and I
YZJK: YZ plane with interpolation parameters J and K
