Contour program:
15 FN 16: Q11 = Q200(Q99) The diametrical gap according to the current power stage is
assigned to Q11 (see ”Indexed assignment” on page 198).
16 FN3 Q11 = Q11 * 0.8 Calculation of the vertical gap
17 L Z+Q11 R0 F M36 Pre-positioning with vertical gap; eroding ON
18 LBL 1 Label number
19 CYCL DEF 11.0 SCALING SCALING cycle
20 CYCL DEF 11.1 SCL Q1 (see ”SCALING FACTOR (Cycle 11)” on page 160)
21 L IY+Q12 R F M Pre-positioning
22 CYCL DEF 14.0 CONTOUR GEOMETRY Cycle 14 Contour Geometry (see ”Cycle 14 CONTOUR
GEOMETRY” on page 137)
