cles
ICP recess turning, radial/axial
Call the recessing menu.
Select the "Recess turning" cycle.
Select the "ICP recess turning, radial" cycle (see
figures at right).
Select "ICP recess turning axial" (see figures on the
following page).
The cycle proceeds as follows, taking oversizes into account:
„ For descending contours, the area defined by X, Z and the ICP
contour is machined.
„ For ascending contours, the area defined by X1, Z1 and the ICP
contour is machined.
See also “Recess turning” on page 143.
Cycle parameters
 X, Z starting point
 X1, Z1, starting point of workpiece blank
 P infeed depth: Maximum infeed depth
 O recessing feed rate —default: Active feed rate
 B offset width —default: 0
 U unidirectional turning —default: 0
„ U=0: bidirectional
„ U=1: unidirectional (direction: see graphic support window)
 I, K oversize X, Z
 N ICP contour number
 T tool number
 S spindle speed / cutting speed
 F feed per revolution
If you are machining:
„ Descending contours, define: Only starting point X,
Z—but not contour starting point X1, Z1.
„ Ascending contours, define: Starting point X, Z and
contour starting point X1, Z1.
