Recessing cycles
Recess turning radial
Recess turning axial
Recess turning (expanded): The cycle machines the defined area
with alternating recessing and roughing motions, taking the optional
contour elements into account.
Recess turning – finishing (expanded): The cycle finishes the defined
contour section, taking the optional contour elements into account.
Information on the cycle parameters:
O:
Recess feed rate
R: Rounding (on both sides of contour valley)
B1, B2: Chamfer or rounding (B1 contour start; B2 contour end)
• B>0: Rounding radius
•
B<0: Chamfer width
B: Offset width
U: Turning operation unidirectional
• U=0: bidirectional
• U=1: unidirectional
Recess turning: The cycle does not take oversizes into ac-
count in the normal mode.
Recess turning – Finishing: The tool returns to the ”start point
X, Z” at the end of the cycle.
