Required for enabling 3D view in part program simulation. 3D simulation can be viewed even in
real-time simulation. Without this option, it is possible to see 2D simulation (with different views)
in the system.
If simultaneous recording option already exists in the system, then it is possible to have 3D view
during the real-time simulation.

When the contour handwheel function is activated, the handwheel has a velocity-generating
effect in AUTOMATIC and MDI modes on all programmed traversing movements of the path and
synchronized axes.
A feedrate specified via the CNC program becomes ineffective and a programmed velocity profile is
no longer valid. The feedrate, in mm/min, results from the handwheel pulses as based on pulse
weighting (machine data) and the active increment. The handwheel's direction of rotation
determines the direction of travel:
Clockwise:
in the programmed direction of travel (even beyond block boundaries)
Counter-clockwise:
against the programmed direction of travel (continuation beyond the start of the block is
prevented).
The following real-time drive variables can be accessed/evaluated in part program:
$AA_LOAD drive capacity utilization in Percentage (%)
$AA_POWER drive active power in Watts (W)
$AA_TORQUE drive torque set point in Newton meters (Nm)
$AA_CURR actual axis/spindle current in Ampere (A)
These variables can be used along with synchronized options
These variables can be also read through PLC interface, NC variables DB1200.DBxxxxx. For the PLC
purpose, evaluation of internal drives is standard.
Application examples :
Evaluation of these drive variables also permits machines and tools to be protected from
overloading, as well as shorter machining times and an improved surface quality for the
workpieces to be achieved. Evaluation of internal drive variables is a prerequisite for implementing
adaptive control (AC).
Adaptive control can be parameterized within the part program as follows:
Additive influence: The programmed feed value is corrected by adding.
Multiplicative influence: The feed value is multiplied by a factor (override).

G_NC01_EN_00583
A safe position is assumed from the machining level without any collision between tool and
workpiece.
As well as the drive-autonomous stop and retract function, the CNC-controlled stop and retract
functionality is also provided. To permit gentle interpolated retraction on the path or contour, the
path interpolation can be processed further for a definable period following the triggering event.
The retraction axes are subsequently traversed in synchronism to an absolute or incremental
position as programmed.
These functions are primarily used for gearing and grinding technologies.

Up to 1 × synchronous spindles/multi-edge turning or master value coupling/curve table
interpolation or axial coupling in the machine coordinate system
Application example:
Multi-edge machining (polygonal turning)
The synchronous spindle function provides the basis for multi-edge machining through
specification of an integer gear ratio between leading spindle and following spindle. In the picture
above, spindle 2 contains the job and spindle 1 has the cutting tool. Both the spindles are
synchronized and run at a ratio (e.g.: 1:6), in order to get polygon shape on the job.

This option is suitable for the hobbing process. Gear hobbing machines are machines which have a
rotating multiple-tooth cutting tool to produce teeth on helical gears, worm gears, cycloid gears,
etc.
When two axes (e.g. tool axes) with different ratio must be coupled on to third axes (e.g. blank
axes).

G_NC01_XX_00121
The Inclined axis function is used for fixed-angle interpolation using an oblique infeed axis (used
primarily in conjunction with cylindrical grinding machines). The axes are programmed and
displayed in the Cartesian coordinate system.
Tool offsets and work offsets are also entered in the Cartesian system and transformed to the real
machine axes.
For oblique plunge-cutting with G05, it is necessary to program the start position with G07.
Bi-directional compensation
G_NC01_EN_00585
Bidirectional compensation is an expansion to the leadscrew error compensation function (LEC) or
the measuring system error compensation function (MSEC). By contrast to LEC and MSEC,
bidirectional compensation works in both directions.
The option supports price sensitive front-face and peripheral side machining applications on lathes
without a mechanical Y axis.
