8.7.9 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
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 radius" softkey.
Parameter Description Unit
The tool travels in the programmed direction from the circle starting point to its end
point. You can program this direction as clockwise or counterclockwise.
Clockwise direction of rotation
Direction of rotation
Counterclockwise direction of rotation
X Target position X (abs) or target position X referred to the last programmed
position (inc)
