With the latest CNC generation, Sinumerik One, Siemens is presenting their latest component for the digital transformation of machine tools at EMO 2019. As a "digital native", the controller features software for the creation of corresponding digital twins. A range of technology functions are intended to help improve processing speed, contour accuracy and processing quality.
To work with the processing speed, the Top Speed function is available, which supports machine operation at the physical limits of the machine. In mold construction, Top Speed works to ensure contour accuracy at high speeds and works hand in hand with the Top Surface technology function. If DYNPREC (Dynamic Precision) is activated via the High Speed Setting Cycle, delicate parts are manufactured with precision. The Intelligent Load Control (ILC) function works to increase the dynamics of the machine. ILC takes into account the current weight of the workpiece when accelerating the machine axes and adjusts them as soon as the machine is no longer loaded to the maximum workpiece weight. With Intelligent Dynamic Control (IDC), the dynamic and control parameters for the machine axes can be balanced across the axes. When this function is set, the parameters are optimized in the working area of the machine, making the machine more precise. The CNC Sinumerik 840-D sl will also support technology functions such as IDC and ILC.
In addition to Sinumerik One, Siemens is also presenting the associated digital services at EMO 2019, which support machine users and machine manufacturers in the creation of a digital twin and with virtual machine commissioning. With the digital twin, activities such as running in new NC programs can be moved to the virtual world. NX Virtual Machine Tool Services support machine manufacturers and machine operators in the creation of the digital twin. From engineering and implementation through to training and support services, Siemens covers the entire lifecycle of the digital twin for the machine tool. Sinumerik One Virtual Commissioning Services offer machine tool manufacturers support when moving commissioning tasks to the virtual world.
The engineering basis for Sinumerik One is the TIA Portal. In this engineering framework with modern programming languages and data flow, PLC, Safety and even HMI can be configured.
Visitors to EMO will be able to see Sinumerik One and its digital twin live in action. Over 20 pilot customers are presenting machine tools with Sinumerik One – either as a digital twin or as a real machine.
