New cycle functions of software 34056x-04,
73498x-02
New Cycle 225 EngravingSee "ENGRAVING (Cycle 225, DIN/
ISO: G225)", page 270
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,
software option 19)", page 148
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,
software option 19)", page 152
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, software option 17)",
page 292
New Touch Probe Cycle 484 for calibrating the wireless TT 449
touch probe See "Calibrating the wireless TT 449 (Cycle 484,
DIN/ISO: G484, software option 17)", page 453
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 48
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 432
Return of offset errors (change of machine datum) in the
parameters Q147-149 See "Cycle run", page 420
Up to eight plane measuring points for the measurement of
spheres See "Cycle parameters", page 429
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).
