By setting the following optional parameters, you can define
additional contour elements:
„ W: Oblique cut at contour end
„ R: Rounding (in both corners of the contour valley)
„ B1: Chamfer/Rounding at contour start
„ B2: Chamfer/Rounding at contour end
Cycle run
1 Calculate the proportioning of cuts (infeed).
2 Approach workpiece on paraxial path for first pass from X, Z.
3 Plunge-cut at plunging angle A with reduced feed.
4 Move to contour end point Z2 or contour end point X2, or if
defined, to one of the optional contour elements at programmed
feed rate.
5 Depending on algebraic sign of P:
„ P>0: Machine contour outline.
„ P<0: Retract at angle of 45°.
6 Return and approach for next pass.
7 Repeat steps 3 to 6 until contour end point X2 or Z2 is reached.
8 Return to starting point on paraxial path.
