New cycle functions of software 34059x-02
New fixed cycle 225 Engraving, see "ENGRAVING (Cycle 225,
DIN/ISO: G225)", page 290
With Cycle 256, Rectangular Stud, a parameter is now available
with which you can determine the approach position on the
stud, see "RECTANGULAR STUD (Cycle 256, DIN/ISO: G256)",
page 156
With Cycle 257, circular stud milling, a parameter is now
available with which you can determine the approach position
on the stud, see "CIRCULAR STUD (Cycle 257, DIN/ISO: G257)",
page 160
New cycles for radial recessing (radial/axial), see "SIMPLE
RADIAL RECESSING (Cycle 841, DIN/ISO: G841)", page 347
With the new blank form update function, the TNC detects
areas with residual material during turning operations and
can then machine them selectively, see "Blank form update
(FUNCTION TURNDATA)", page 298
Cycle 402 now also allows you to compensate workpiece
misalignment by rotating the rotary table, see "BASIC
ROTATION over two studs (Cycle 402, DIN/ISO: G402)",
page 422
New Touch Probe Cycle 484 for calibrating the wireless TT 449
touch probe, see "Calibrate the wireless TT 449 (Cycle 484,
DIN/ISO: G484 Touch Probe Functions software option 17)",
page 587
New manual probing cycle "Center line as datum" (see User's
Manual)
Predefined values can now be entered into a cycle parameter
with the PREDEF function in cycles, see "Program defaults for
cycles", page 56
The following improvements were made to the KinematicsOpt
cycles:
Newer, faster optimization algorithm
After angle optimization, a separate measurement series
is no longer required for position optimization, see "Various
modes (Q406)", page 566
Return of the offset errors (change of machine datum) to the
parameters Q147 to 149, see "Cycle run", page 554
Up to eight plane measuring points for the measurement of
spheres, see "Cycle parameters", page 563
The active tool-axis direction can now be activated in manual
mode and during handwheel superimposition as a virtual tool
axis (see User's Manua).
