New computer numerical control for compact class machine tools

28.08.2009
The new Sinumerik 828D numerical control adds a compact class model to the Siemens Drive Technologies range of machine tool controls.

The control includes such exacting CNC functions as kinematic transformations and an efficient tool management system. CNC, PLC, operator panel and axis control for six CNC measurement circuits are combined in a robust operator panel control. The system software is precisely tailored to address the needs of complex turning and milling machines for shopfloor applications.


The Sinumerik 828D is capable of full graphic, high-level language command or ISO programming, making it appropriate for job shops around the world.

Siemens Drive Technologies has extended its portfolio of controls to include an efficient CNC for compact class machine tools. With this new addition, alongside the Sinumerik 802D sl for standard machine applications and the 840D sl for high-end machining applications, users are now offered the option of the Sinumerik 828D, a new system designed to address the needs of complex turning and milling machines in the job shop segment. Complete with intelligent kinematic transformations, an efficient tool management system and 80-bit precision, the new control benefits from a range of performance features previously reserved exclusively to the premium CNC control segment.

The Sinumerik 828D is suitable for both single part and small batch, as well as large-scale series production. Use of the ShopMill and ShopTurn graphic workstep programming systems helps reduce programming time when producing small batch sizes. For large-scale series production, high-level language programming, in conjunction with programGuide for technology cycle parameterization significantly reduces programming times. In addition, the Sinumerik 828D also supports ISO programming that is customary in Asia and the United States. With these options, Sinumerik 828D is capable of working with every type of CNC programming method used around the world. This opens the scope to machine manufacturers for global marketing of their products with just a single CNC equipment option.

The Sinumerik 828D makes available modern PC and cell phone technology to the compact machine class for the first time. Extensive graphical online help, animations and a new type of input prompting system with moving picture sequences provide the basis for exceptional user convenience. USB, Compact Flash (CF) card and Ethernet ports permit simple high-speed data transfers onto storage media or integration of the control system into corporate networks. With its Easy Message functionality, the Sinumerik 828D offers process monitoring by text messaging (SMS). Depending on the recipient’s profile setting, the machine will transmit information about workpiece machining status, report on the tool condition currently in use and even send machine maintenance bulletins. The combination of these functions permits machine downtime to be reduced to a minimum.

The Sinumerik 828D can be configured for milling or turning applications. The milling version is precisely tailored to the requirements of vertical machining centers with additional machine units such as an A-axis for machining cylindrical workpieces or a swivel facility for machining inclined workpiece planes. Using Advanced Surface, the intelligent path guidance system, the Sinumerik 828D can also be used for the production of high-precision molds. The turning version is specifically designed for single-channel inclined-bed lathes. Alongside powered tools for face and outer surface machining, with and without Y-axis, the system also supports a fully functional counter spindle. Because the turning and milling versions are precisely tailored to the relevant machine category, the system software is substantially less complex in comparison with universal systems.,System parameters are precisely pre-defined, reducing the work involved in commissioning to a minimum for the machine manufacturer. With Easy Extend, the machine tool builder is also offered a simple way of managing additional components such as indexing tables or bar loaders. Specialized CNC expertise is no longer required for mounting components in the field, representing a considerable saving in terms of servicing expenditure.

The Sinumerik 828D is available with a horizontal and vertical control panel layout. Both control panel versions come in a choice of two CNC performance variants, allowing the Sinumerik 828D to be ideally adjusted to specific mounting requirements and individual machine performance requirements. Its minimal dimensions allow the new Sinumerik to be easily integrated into even the most compact machine designs. Despite the reduced size of the control, the high-resolution 10.4” color TFT display and fully functional QWERTY keyboard make for make it extremely user-friendly. The structural design of the CNC, a unit comprising of a highly tough and wear-resistant die cast magnesium control panel, CNC keyboard and CNC electronic circuitry, is extremely robust and features only a minimal number of interfaces. The new CNC is maintenance-free with no fans, hard drive or backup battery.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
