Cycle run
1 Calculate the proportioning of cuts (infeed).
2 Approach workpiece for first pass from X, Z.
3 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.
4 Depending on algebraic sign of P:
„ P>0: Machine contour outline.
„ P<0: Retract at angle of 45°.
5 Retract and approach for next pass.
6 Repeat steps 3 to 5 until X1 or Z1 is reached.
7 Return to starting point on paraxial path.
