4.3 Single Cut Cy
cles
Circular machining
Call the single-cut menu.
Select the "Circular machining cycle" (clockwise).
Select the "Circular machining cycle"
(counterclockwise).
With return soft key:
Off: When the cycle is completed, the tool remains at
the cycle end position.
On: Tool returns to the starting point.
Circular machining
The tool moves in circular arc from the starting point to the contour
end point at the programmed feed rate and remains at the cycle end
position.
Contour circular ("With return")
The tool approaches the workpiece, executes the circular cut and
returns to the starting point at the end of cycle. Cutter radius
compensation is taken into account (see figures at right).
Cycle parameters
 X, Z starting point
 X1, Z1 starting point of contour (if "With return" is active)
 X2, Z2 contour end point
 R radius of rounding
 T tool number
 S spindle speed / cutting speed
 F feed per revolution
Cycle run (if "With return" is active)
1 Move on paraxial path from X, Z to contour starting point X1, Z1.
2 Move in circular arc to contour end point X2, Z2 at programmed
feed rate.
3 Retract and return to starting point on paraxial path.
