4.17 Contour-Based Turning Cycles
Recessing G860
G860 machines the defined contour area. The reference to the
contour to be machined can be transferred in the cycle parameters, or
the contour can be defined directly after the cycle call (see “Working
with contour-based cycles” on page 246). The contour to be machined
may contain various valleys. If required, the area to be machined is
divided into several sections.
Parameters
ID Auxiliary contour—ID number of the contour to be machined
NS Start block number
 Beginning of the contour section, or
 Reference to a G22/G23-Geo recess
NE End block number (end of contour section)
 NE not programmed: The contour element NS is machined
in the direction of contour definition.
 NS=NE programmed: The contour element NS is machined
opposite to the direction of contour definition.
 NE is inapplicable if the contour is defined by G22/G23-Geo
I Oversize in X direction (diameter value)—(default: 0)
K Oversize in Z direction (default: 0)
Q Action (default: 0)
 0: Roughing and finishing
 1: Only roughing
 2: Only finishing
X Cutting limit in X direction (diameter value)—(default: no
cutting limit)
Z Cutting limit in Z direction (default: no cutting limit)
V Identifier start/end (default: 0) A chamfer/rounding arc is
machined:
 0: At start and end
 1: At the start
 2: At end
 3: No machining
E Finishing feed rate (default: active feed rate)
EC Period of dwell
