New and changed cycle functions of software
81760x-05
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,
software option 17)", Page 487
New Cycle 276 3-D Contour Train see "THREE-D CONT. TRAIN
(Cycle 276, DIN/ISO: G276, software option 19)", Page 233
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, software option 19)", Page 229
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, software option 19)", Page 172, see "CIRCULAR STUD
(Cycle 257 , DIN/ISO: G257 , software option 19)", Page 177
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 328
Cycles 205 and 241: The feed rate behavior was modified. see
"SINGLE-LIP DEEP-HOLE DRILLING (Cycle 241, DIN/ISO: G241,
software option 19)", Page 101, see "UNIVERSAL PECKING
(Cycle 205, DIN/ISO: G205, software option 19)", Page 90
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, software option 19)", Page 186
CONTOUR DEF can be programmed in DIN/ISO
The technically obsolete cycles 1, 2, 3, 4, 5, 17 , 212, 213, 214,
215, 210, 211, 230, 231 subordinated in "old cycles" can no
longer be inserted via the editor. These cycles can however still
be modified and executed.
The tool touch probe cycles 480, 481, 482 can be hidden see
"Setting machine parameters", Page 524
Cycle 225 Engraving can engrave the current counter reading
with a new syntax see "Engraving the counter reading",
Page 322
New column SERIAL in the touch-probe table see "touch probe
data", Page 341
