4.5 Recessing cy
cles
Cycle run
1 Calculate the proportioning of cuts
2 Approach the workpiece from starting point for first pass
3 Execute the first cut (recessing)
4 Machine perpendicularly to recessing direction (turning)
5 Repeat 3 to 4 until contour end point X2, Z2 is reached
6 Return to starting point on paraxial path
7 Move to the tool change point according to the G14 setting
Recess turning, axial
Call the recessing cycles
Select recess turning
Select recess turning, axial
The cycle clears the rectangle described by the starting point and
contour end point.
