Integrated automation solutions for the entire process chain

28.03.2008
Integrated drive and automation solutions for machine tools will be the focal point of the presentation by Siemens Drive Technologies at this year's METAV trade fair. The range covers everything from CNC solutions with the Sinumerik solution line series of controls, through software tools like ShopMill and ShopTurn, right up to services for condition monitoring or machine simulation with Mechatronic Support.

In Hall 3, Booth A40 of the show in Duesseldorf, Germany, the Siemens Drive Technologies Division will present products, services, and solutions for machine tools on the shopfloor, and for complex applications.

The focus will be on examining the entire process chain with CAD/CAM processes, the simulation of products, machines, and production with PLM software and tools such as Mechatronic Support or Virtual NC, and applications for condition monitoring.

At the heart of these solutions is the Sinumerik control system. With Profinet connection, the Sinumerik 840D sl machine tool control now also acts as a Profinet controller to drive distributed I/O or to control the Sinamics S120 system as a positioning drive. Both cable-based connections and WLAN communications can be used for this purpose. Flexible production systems require the transfer of large, consistent data blocks in short cycle times, and this is now possible with Sinumerik 840D sl and Profinet CBA. For machine manufacturers, this means more flexibility thanks to modular and mechatronic machine concepts.
In parallel with this, powerful communications with other controllers, such as OPC servers or the service programming device is possible at any time. The Sinumerik 840D solution line control system also has new, integral safety functions. They meet all the requirements to SIL2 (Safety Integrity Level/IEC 61508) as well as PL d (Performance Level/EN ISO 13849-1). Safe communications between several Sinumerik 840D sl systems using standard Profibus significantly simplify plant installation.

The new functions of the ShopTurn and ShopMill programs for the shopfloor significantly reduce the programming time for CNC applications, and thus increase productivity at the shopfloor level. The technology packages are just as suitable for cycle-controlled flatbed machines, inclined bed lathes, and horizontal or vertical turning and milling centers, as they are for complex machining centers in tool and mold making. Use of the "fingerprint" for status monitoring of machine tools will be presented. An electronic "fingerprint" of the machine is created prior to initial delivery. This is then used during operation as a reference for changes. The differences can be used to diagnose faults and thus determine the ideal time for maintenance.

Siemens will also collaborate with seven partner companies at the special Booth D79 in Hall 3 of the METAV fair to demonstrate total solutions over the entire process chain. The highlight here, billed as "Top Team 4 Productivity", will be the blade-milling project for Olympic bobsleigh champion Sandra Kiriasis. The CNC process chain, from the CAD application, through simulation of the workpiece, right up to the actual milling with a Sinumerik program, will be shown using this specific order for milling bobsleigh blades.

The Siemens Motion Control Systems (MC) Business Unit acted as coordinator for the companies participating in this project: Iscar as the manufacturer of tools, Sescoi Work NC for CAD/CAM software, Renishaw for the measuring systems, Chick Spannsysteme GmbH, and CNC-Arena. "With this project at the special booth, we demonstrate our competence across the entire CNC process chain – competence that we as the project coordinator put to use to the profit of the customer", says Uwe Haeberer, Head of Machine Tools at Siemens Drive Technologies.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
