New and modified cycle functions 34059x-08
New Cycle 453 KINEMATICS GRID. This cycle makes it
possible to probe a calibration sphere in multiple tilting-axis
positions predefined by the OEM. The measured deviations
can be compensated via compensation tables. Options 48
KinematicsOpt and 52 KinematicsComp are required; the
machine tool builder has to adapt the feature to the respective
machine.
New Cycle 441 FAST PROBING. With this cycle you can set
various touch probe parameters (e.g. positioning feed rate) that
are globally effective for all subsequently used touch probe
cycles.
Cycles 256 RECTANGULAR STUD and 257 CIRCULAR STUD
were extended by the parameters Q215, Q385, Q369 and
Q386.
The recessing cycles 860 to 862 and 870 to 872 were extended
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.
Cycle 239 ascertains the current load of the machine axes with
the LAC control function. In addition, Cycle 239 can now also
adjust the maximum axis acceleration. Cycle 239 supports the
determination of the load on synchronized axes.
The feed rate behavior in Cycles 205 and 241 was changed.
Changes of details in Cycle 233: Monitors the tooth length
(LCUTS) during finishing, increases the area by Q357 in the
milling direction when roughing with milling strategies 0 to 3
(provided that no limit has been set in the milling direction)
The technologically outdated Cycles 1, 2, 3, 4, 5, 17, 212, 213,
214, 215, 210, 211, 230, and 231 grouped under OLD CYCLES
can no longer be inserted using the editor. These cycles can still
be executed and edited, however.
The tool touch probe cycles, such as Cycles 480, 481 and 482,
can be hidden
Cycle 225 Engraving can engrave the current counter reading by
using a new syntax.
New SERIAL column in the touch probe table
Enhancement of the contour train: Cycle 25 with Residual
Material Machining, Cycle 276 Three-D Contour Train
