Tool offsets
8.11 Smooth approach and retraction
Fundamentals
8-44 Programming Manual, 10.2004 Edition, 6FC5 298-7AB00-0BP1
Parameters
G140 Approach and retraction direction independent of the
current compensation side (basic setting)
G141 Approach from the left or retraction to the left
G142 Approach from the right or retraction to the right
G143 Approach and retraction direction depends on the relative
position of the start and end point with respect to the
tangent direction
G147 Approach with a straight line
G148 Retraction with a straight line
G247 Approach with a quadrant
G248 Retraction with a quadrant
G347 Approach with a semicircle
G348 Retraction with a semicircle
G340 Approach and retraction in space (basic setting)
G341 Approach and retraction in the plane
DISR
Approach and retraction with straight line (G147/G148)
Distance from the mill edge to the start point of the
contour
Approach and retraction with circles (G247, G347/G248,
G348)
Radius of the tool center point path
Caution: In the case of REPOS with a semicircle, DISR is
the diameter of the circle
DISCL DISCL=... Distance from the end point of the
fast infeed motion to the machining plane
DISCL=AC(...) Specifies the absolute position of the end
point of the
fast infeed motion
FAD Speed of the slow infeed motion
FAD=... the programmed value applies according to the
G code of group 15 (feedrate; G93, G94, etc.)
FAD=PM(...) the programmed value is interpreted as a
linear feedrate (as G94), independently of the active G
code, group 15
FAD=PR(...) the programmed value is interpreted as a
revolutional feedrate (as G95), independently of the
active G code, group 15.
