New and changed cycle functions of software
34059x-08
New Cycle 453 KINEMATICS GRID. This cycle makes it possible
to probe a calibration sphere in tilting-axis positions predefined
by the machine tool builder. The measured deviations can be
compensated with the aid of compensation tables. Options
48 KinematicsOpt and 52 KinematicsComp are needed; the
machine tool builder must adapt the function to the specific
machine. See "KINEMATICS GRID (Cycle 453, DIN/ISO: G453,
option)", page 710
New Cycle 441 FAST PROBING. You can use this cycle to
globally specify various touch probe parameters (e.g. the
positioning feed rate) for all subsequently used touch probe
cycles. See "FAST PROBING (Cycle 441, DIN/ISO G441)",
page 652
New Cycle 276 3-D Contour Train See "THREE-D CONT. TRAIN
(Cycle 276, DIN/ISO: G276)", page 241
Enhancement of the contour train: Cycle 25 with machining of
residual material, the cycle was expanded with the following
parameters: Q18, Q446, Q447 , Q448 See "CONTOUR TRAIN
(Cycle 25, DIN/ISO: G125)", page 237
Cycles 256 RECTANGULAR STUD and 257 CIRCULAR STUD
have been expanded to include parameters Q215, Q385, Q369
and Q386. See "RECTANGULAR STUD (Cycle 256, DIN/ISO:
G256)", page 180, See "CIRCULAR STUD (Cycle 257 , DIN/ISO:
G257)", page 185
The recessing cycles 860 to 862 and 870 to 872 were expanded
by the input parameter Q211. In this parameter, a dwell time
can be specified in revolutions of the workpiece spindle, which
retards the retraction after the recessing on the floor. See
"RECESSING CONTOUR RADIAL (Cycle 860, DIN/ISO: G860)",
page 445, See "RADIAL RECESSING (Cycle 861, DIN/ISO:
G861)", page 437, See "RADIAL RECESSING EXTENDED
(Cycle 862, DIN/ISO: G862)", page 441, See "AXIAL
RECESSING (Cycle 870, DIN/ISO: G870)", page 458, See
"AXIAL RECESSING (Cycle 871, DIN/ISO: G871)", page 450,
See "AXIAL RECESSING EXTENDED (Cycle 872, DIN/ISO:
G872)", page 454
Cycle 239 can ascertain the current load of the machine
axes with the control function LAC. Cycle 239 can now also
modify the maximum axis acceleration. Cycle 239 supports
the determination of the load on synchronized axes. See
"ASCERTAIN THE LOAD (Cycle 239, DIN/ISO: G239, software
option 143)", page 351
Cycles 205 and 241: The feed rate behavior was modified.
See "SINGLE-LIP DEEP-HOLE DRILLING (Cycle 241, DIN/ISO:
G241)", page 109, See "UNIVERSAL PECKING (Cycle 205,
DIN/ISO: G205)", page 98
Detail changes with Cycle 233: Monitors length of the cutting
edge (LCUTS) with finishing operations, when roughing with
the milling strategy between 0 to 3, the surface in the milling
direction is increased by the value from Q357 (provided that no
limitation is set in this direction) See "FACE MILLING (Cycle 233,
DIN/ISO: G233)", page 194
