40 LBL 2
41 LP PR+Q6 PA+Q24 R0 FQ12 Move upward in an approximated “arc”
42 FN 2: Q24 = +Q24 - + Q14 Update solid angle
43 FN 11: IF +Q24 GT +Q5 GOTO LBL 2 Inquire whether an arc is finished. If not finished, return to LBL 2.
44 LP PR+Q6 PA+Q5 Move to the end angle in space
45 L Z+Q23 R0 F1000 Retract in the tool axis
46 L X+Q26 R0 F MAX Pre-position for next arc
47 FN 1: Q28 = +Q28 + +Q18 Update rotational position in the plane
48 FN 0: Q24 = +Q4 Reset solid angle
49 CYCL DEF 10.0 DREHUNG Activate new rotational position
50 CYCL DEF 10.1 ROT+Q28
51 FN 12: IF +Q28 LT +Q9 GOTO LBL 1
