Procedure
1. The ShopMill program to be edited has been created and you are in the
editor.
2. Press the menu forward key and the "Straight Circle" softkey.
3. Press the "Circle center point" softkey.
Parameter Description Unit
Direction of rotation 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
X Target position X (abs) or target position X referred to the last programmed position
(inc)
mm
Y Target position Y (abs) or target position Y referred to the last programmed position
(inc)
mm
I Distance between circle starting point and center point in X direction (inc.) mm
J Distance between circle starting point and center point in Y direction (inc.) mm
F Machining feedrate mm/rev
mm/min
mm/tooth
PL Plane: The circle is traversed in the set plane with the relevant interpolation param‐
eters:
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

10.7.10 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.
