4.3 Single Cut Cy
cles
Chamfer
Call the single-cut menu.
Select the "Chamfer" cycle.
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.
Chamfer
The cycle produces a chamfer that is dimensioned relative to the
corner of the workpiece contour. When the cycle is completed, the
tool remains at the cycle end position.
Contour chamfer ("With return")
The tool approaches the workpiece, machines the chamfer that is
dimensioned relative to the corner of the workpiece contour 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 contour corner
 A starting angle: Angle of the chamfer, range: 0°< A < 90°
 I, K chamfer width (in X, Z)
 J element position (see graphic support window)—default: 1
„ Position is relative to X1, Z1
„ Algebraic sign determines cutting direction
 T tool number
 S spindle speed / cutting speed
 F feed per revolution
Parameter combinations for defining the chamfer:
„ I (45° chamfer)
„ K (45° chamfer)
„ I, K
„ I, A
„ K, A
Cycle run (if "With return" is active)
1 Calculate starting point and end point of chamfer.
2 Move on paraxial path from X, Z to starting point of chamfer.
3 Move to end point of chamfer at programmed feed rate.
4 Retract and return to starting point on paraxial path.
