Robust Software Functions Improve CNC Milling, Grinding Turning

Siemens Industry makes available its mid-range CNC, the Sinumerik 828D, with a version 4.8 operating system. With the version release, Siemens now offers an array of new hardware and software solutions for its integrated Sinumerik portfolio, comprising integrated industrial software and automation technology designed to enable machine tool manufacturers to leverage the full productivity potential of the digital factory in a mid-range control. 

Sinumerik 828D is a compact, panel-based CNC designed for turning, milling and grinding operations. It is offered in vertical and horizontal models for highly flexible machine design integration and enables optimum surface finishes with 80-bit nano floating point accuracy. Up to 10 axes of motion with two auxiliary axes are possible.

The Sinumerik CNC software release 4.8 makes a range of new functions available to improve the speed, precision and safety of intermediate milling, turning and grinding machine tools, with simplified ISO code programming. Features of version 4.8 include facility for compensating unwanted axis nodding movements and protection against machine, tool and workpiece collisions. Nodding compensation (NoCo) is used to compensate for dynamic position deviations in one or more linear machine axes caused by acceleration processes. It can be used in conjunction with any technology, such as milling, multitasking, tapping, laser machining or water jet machining. NoCo is available in two variants: Eco and Advanced. 

The software release also features a collision protection: Collision Avoidance Eco and Collision Avoidance Advanced. The Eco version enables machine protection by preventing collisions of the machine body with its own components within the work area. To achieve this effect in real time, the assemblies which need protection are calculated as simple geometric bodies. This collision monitoring system is available in all three operating modes: JOG, MDA and Automatic. The protected areas can be engineered and visualized as a 3D image at the control interface.
