Motion platform for robotics, CNC, position

Generic motion control combines the worlds of robotics, CNC, linked axis movements and single axis positioning.

Anthropomorphic robots, complex CNC 3D processing, multiply linked axis movements, single-axis positioning that can be modified in real-time were separate areas of technology until B&R introduced Soft CNC, a complete platform combining all the necessary components in one system. “Generic Motion Control” includes drives, movement and path control, visualization, and I/O handling. In particular, path control with CNC functionality works as an integral part of the complete automation system, which can be configured with one software tool.
The company says the platform’s real-time operating system creates the environment needed for high-precision positioning tasks. CNC cycle times of 400
Predefined visualization components can also be used to create complex machine functions. In addition to “classic” components, such as parameter configuration and movement program operation, this also includes tools for simulation, logging and process diagnostics. This provides the foundation for all custom visualization solutions.
The company says flexible system architecture and the large number of functions make it possible to customize a machine line to meet specific customer requirements, since the actual expertise of an automation solution can be encapsulated in the application layer rather than built directly into the CNC core.
The Soft CNC has an extensive list of functions. Part programs and movement procedures are programmed according to DIN 66025. Division into main and sub-programs allows clear management of NC programs. Helpful functions also have been added to the basic functions defined in the standard. The extended programming techniques permit the use of elements from a high level language, such as loops, conditional statements and branches.
The company says data from application programs on the PLC is exchanged using a powerful interface. Various access functions allow program execution to be controlled in real-time. Data, such as the tool radius or even end points of path sections, can be changed while the program is being executed, and certain data is available synchronous to the path.
