Recessing G860 - HEIDENHAIN CNC PILOT 640 User Manual

DIN/ISO programming | 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.
"Working with contour-based cycles", Page 315
Further information:
The contour to be machined can 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: Starting block no. of contour – beginning of contour section
Beginning of contour section
Reference to a G22/G23-Geo recess
NE: Contour end block no. – 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.
I: O-size X
K: O-size Z
Q: Roughing/Finish – procedure (default: 0)
0: Roughing and finishing
1: Only roughing
2: Only finishing
X: Cutting limit in X (diameter value; default: no cutting limit)
Z: Cutting limit in Z (default: no cutting limit)
V: Machine form elements (default: 0)
A chamfer/rounding arc is machined
0: At beginning and end
1: At beginning
2: At end
3: No machining
E: Finishing feed
EC: Delay
D: Rev. on recessing floor
H: Kind of liber. at end of cycle
0: Back to start point
Axial recess: First Z, then X direction
Radial recess: First X, then Z direction
1: Before finished contour
2: Stops at safety clear.
B: Cut. width
P: Cut depth by which one cut is fed
