Thanks to its superior CNC performance, outstanding flexibi-
lity and open architecture, the Sinumerik 840D sl is the basis
for nearly every machine concept. A powerful hardware ar-
chitecture and intelligent control algorithms ensure superior
dynamic performance and accuracy when machining on mul-
titasking machines such as mill-turn machines or turn-mill
machines. Through consistent further development, Siemens
further drives both the CNC functionality and the usability of
the Sinumerik 840D sl – which increases the efficiency and
productivity of machines used in metalworking.
Increased profitability in moldmaking – the focus lies on high-speed cutting
In the context of further development, Siemens has deve-
loped new functions and improved the simulation on Sinu-
merik 840D sl, which enhances the usability and flexibility
for the user, in particular with HSC (High Speed Cutting).
Regarding the Sinumerik MDynamics technology package
for 3-axis and 5-axis milling applications, from now on an
integrated HSC image for high-speed cutting is provided.
This allows to display all the relevant information on mold-
making and motion control with Advanced Surface on one
screen. Further, all G-Code functions for moldmaking appli-
cations including the programmed tolerances can now be
optically marked. This provides the user a better overview
and thus improves safety. The technology of the correspon-
ding machining cycle, Cycle832, has also been further de-
veloped. The machining type can now be output as a plain
text, and the orientation tolerance can be entered direct-
ly in the relevant screen, which improves the usability for
high-speed cutting.
By introducing new features, Siemens enhances the productivity and precision of high-end CNC Sinumerik 840D sl.
In the course of the consistent further development of CNC Sinumerik 840D sl, the Siemens Drive Technolo-
gies Division focuses on continuous hardware and software improvements and further drives the producti-
vity and precision of the high-end CNC by introducing new functions and further optimizing the usability.
Regarding the Sinumerik MDynamics technology package, intelligent function extensions for 3-axis and
5-axis milling applications help increase the efficiency of machines, in particular in high-speed cutting.
Reliable protection against unvoluntary collisions is ensured by the ‘Collision Avoidance’ function in Sinu-
merik. Further, the new compile cycle ‘Nodding Compensation’ ensures increased precision during work-
piece machining.

More reliable protection against collisions – also for complex machining operations
Collision Avoidance in Sinumerik allows to prevent colli-
sions of machine components in the working area of the
machine tool. In a first step, Collision Avoidance is concen-
trated on the most critical situations arising in practice –
when setting up the machine or in case of interrupted ma-
chining: That means, whenever the operator intervenes in
the process.
Thanks to a powerful and intelligent system architecture,
the 3D real-time collision monitoring function is active
even with complex machining operations such as 5-axis si-
multaneous milling or turning with B axis. In this context,
static and mobile machine components as well as the tool
cutting edge are effectively monitored for collisions.
The fully-fledged 3D visualization allows to display the
complete machining process, including the machining
room, on the CNC screen. Further, this allows to quickly
and effectively identify the area subject to significant col-
lision risk.
For collision monitoring with the workpiece, Siemens has
already provided for some time the well-proven offline ma-
chine simulation in NX CAM, which allows to effectively
prevent collisions already when defining the relevant pro-
cesses on the PC. The machine model is configured through
a user-friendly definition of cuboids, balls, cylinders or the
import of STL files directly via the CNC user interface.
In addition, Siemens – a single-source provider of CNC
technology and product lifecycle management solutions –
provides a user-friendly alternative. With NX Sinumerik
Collision Avoidance, machine manufacturers can quickly
and conveniently read in the machine model for collision
monitoring on PC from the existing machine design data,
simplify it and transfer it directly to the Sinumerik.
It goes without saying that Collision Avoidance in Sinume-
rik automatically generates the data for collision monito-
ring of the tool cutting edges from the tool data available
for machining. This automatically includes collision moni-
toring with the machine component model without additi-
onal operator maintenance.
New compile cycle increases the precision on the workpiece
By adopting mechatronic optimization measures, Siemens
can react to all requirements arising in special applications,
for example, in moldmaking. This has generated the com-
pile cycle ‘Nodding Compensation’, which is important,
for example, for gantry-type machines, where the tower
can ‘nod’ by accelerating and decelerating the other axes.
That means, it is excited by its own inertia in the natural
resonances. This cannot be compensated by controlling
the own axes (of the tower) because these signals cannot
be monitored on the own motor encoder. Nevertheless,
the tool tip is lowered into the workpiece where it cau-
ses marks. This is where Nodding Compensation comes
into play: It monitors the other axes (e.g. Y axis) and mo-
dels the system. The acceleration processes of all axes are
known. This allows to predict the nodding and compen-
sate it accordingly, as is the case with feedforward con-
trol. In this way, the Nodding Compensation enhances the
machining accuracy and improves the surface quality. The
open architecture of Sinumerik 840D sl allows to conveni-
ently commission the compile cycle via the user interface
Sinumerik Operate.
With Collision Avoidance Sinumerik optimally protects moving components against unvoluntary collisions with static machine components – in all operating situations.
Sinumerik Integrate for Production: Efficiency increased through IT integration
Siemens further expands vertical machine tool networking.
The Product Suite Sinumerik Integrate for Production pro-
vides answers to the questions that relate to, among other
things, the availability of machinery, maintenance intervals,
the timeliness of the processing program or the access to
geographically distributed machines. In addition, users are
supported in terms of tool and program management as well
as the back up and import of machine data; the Product Suite
also offers transparency with regard to the machine’s energy
consumption and its stock of materials and tools.
These and lots of further questions are answered by the
software running directly on the machine tool controller.
The machine clients are connected to a central server, which
provides different applications. As the machines need be
connected to the server only once and can then be flexibly
extended by new functions, users benefit from convenient,
low-cost commissioning and superior future reliability.
Another specific advantage of this approach is the high
system scalability. As the clients can also run without net-
working, many functions included in Sinumerik Integrate
can already be used on non-networked single machines.
When using several machine tools and aiming at imple-
menting overall optimizations, further functions are sup-
ported through networking. Further, users who already use
engineering data management systems (PLM system) or
manufacturing control systems (MES/ERP) can also connect
these levels.
Thus, customers can use the added value provided by the in-
tegrated Siemens portfolio - from Product Lifecycle Manage-
ment (PLM) and Manufacturing Execution Systems (MES)
through to single Sinumerik controllers – to increase the pro-
ductivity of their machines.
The intelligent integration of IT in manufacturing systems allows to increase the output and, at the same time, reduces
costs. With the new Product Suite “Sinumerik Integrate for Production“, Siemens has been providing a new software
platform since June 2013, which allows both machine manufacturers and end customers to increase their productivity
in production and service.
