HEIDENHAIN CNC PILOT 4290 233
4.21 Simple Turning Cycles
Cycle run
1 Calculates the number of cutting passes (infeeds).
2 Approaches workpiece for first pass from starting point on
paraxial path.
3 Moves at feed rate to target point X.
4 Depending on algebraic sign of K:
 K<0: Machines contour outline
 K>0: Retracts by 1 mm at 45°
5 Returns at rapid traverse and approaches for next pass.
6 Repeats 3 to 5 until target point Z has been reached.
7 Move to:
 X: Starting point of cycle
 Z: Last retraction coordinate
