6.14 Recess-Turning Cycles
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)
