New Options on Siemens Compact CNC Improve Speed and Precision of Intermediate Mill/Turn Tools

At IMTS 2018, Siemens presented its popular mid-range CNC, the Sinumerik 828D, with version 4.8 of the operating system.

With the release of version 4.8, Siemens now offers an array of new hardware and software solutions for its integrated Sinumerik portfolio. The offering comprises 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, offered in vertical and horizontal models for highly flexible machine design integration, while the resident Siemens technologies of Advanced Surface and Top Surface ensure the optimum surface finishes with 80-bit nano floating point accuracy. Also standard on the 828D are the popular Siemens Shop-Mill and Shop-Turn graphical programming with interactive input help through animated elements.

Up to 10 axes of motion with two auxiliary axes are possible. Color displays, in sizes 10.4" or 15.4", and the powerful Simatic S7 PLC are also standard. With three steps in the new software version, depending upon the motion control needed, Siemens is bringing the 828D standard models to a highly competitive price point for the builders of CNC milling, turning and grinding machines.

With its new Sinumerik CNC software release 4.8, Siemens is making 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. These position deviations are caused by what is known as mechanical compliance within the machine. NoCo compensates for the dominant position deviation by initiating a corrective movement in the relevant machine axis, enabling improved machining quality simultaneously with higher jerk and acceleration values.

The Sinumerik software release 4.8 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.
