New cycle functions of software 34059x-02
New Cycle 225 EngravingSee "ENGRAVING (Cycle 225, DIN/
ISO: G225)", page 276
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 154
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 158
New cycles for radial recessing (radial/axial) See "SIMPLE
RADIAL RECESSING (Cycle 841, DIN/ISO: G841)", page 329
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 284
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 404
New Touch Probe Cycle 484 for calibrating the wireless TT 449
touch probe See "Calibrating the wireless TT 449 (Cycle 484,
DIN/ISO: G484)", page 565
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 54
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 544
Return of offset errors (change of machine datum) in the
parameters Q147-149 See "Cycle run", page 532
Up to eight plane measuring points for the measurement of
spheres See "Cycle parameters", page 541
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).
