Recessing G860
G860 machines (indents) the contour area defined by ”NS, NE” axially/
radially.
Parameters
NS, NE: Starting block number, end block number (reference on contour
section or NS = reference on a recess described with G22-/G23-
Geo)
I, K: Allowances (I diameter value) – default: 0
Q: Sequence – default: 0
n Q=0: roughing and finishing
n Q=1: roughing only
n Q=2: finishing only
X/Z: Cutting limit (X diameter value)
V: Machining chamfers/roundings at start/end of contour – default: 0
chamfer/rounding is machined:
n V=0: at beginning and end
n V=1: at beginning
n V=2: at end
n V=3: no machining
E: Finishing feed rate – no input: active feed rate
H: Retraction at end of cycle – default: 0
n H=0: return to starting point (axial recess: first Z and then X
direction; radial recess: first X and then Z direction)
n H=1: position in front of the finished contour
n H=2: move to safety clearance and stop
• Cutter radius compensation: is carried out
• Offsets (G57/G58): are effective
