Recess-turning cycle, longitudinal G815 /
transverse G825
The cycles machine the contour area described by current tool
position and the data defined in the subsequent blocks (see “Contour
definition” on page 310).
Parameters
X cutting limit
(diameter value)
Z cutting limit
P maximum infeed:
The proportioning of cuts is calculated so that an
"abrasive cut" is avoided and the infeed distance is <= P.
I oversize X
(default: 0)
K oversize Z
(default: 0)
Q roughing/finishing
(default: 0)
Q=0: The recess is first rough-machined with consideration of the
oversizes and then finish-machined at finishing feed E.
Q=1: Only roughing
Q=2: Finishing only—"I, K" defines the material to be machined.
U unidirectional turning
(default: 0):
U=0: bidirectional
U=1: Unidirectional
– G815: In direction of spindle
– G825: In direction of contour definition
B offset width
(default: 0)
R turning depth compensation
(default: 0)
O recessing feed rate
(default: Active feed rate)
E finishing feed
(default: Active feed rate)
