New Sinumerik features improve productivity and precision

• Drive optimization called automatically by the part program boosts productivity
• Automatically switching the dynamic values to rapid traverse and interpolation steps, improves both quality and speed
• New compensations increase machine precision and reduce speed-dependent friction effects

Siemens offers new features for increasing machine precision with its software version 4.7 for Sinumerik Operate. User benefit: The new software-supported features increase machining precision while also improving machine productivity.

For example, the Sinumerik Auto Servo Tuning algorithm makes it possible to optimize machine dynamics so that control loop parameters and damping filters can be automatically calculated and adjusted for drive optimization.

Where flexible production leads to changes in the mass of workpieces, tool holders or tools on a machine, the parameters for increasing productivity and quality can be adjusted via Auto Servo Tuning. With the latest software version 4.7 for Sinumerik Operate the algorithm can be activated directly via the CNC program on the Sinumerik 840D sl. As a result, each time the processing parameters change, an optimization occurs between processing steps, leading to superior precision and maximum productivity.

The Adapt Jerk Filter Time (AJET) feature for the Sinumerik 840D sl starts by optimizing motion sequences. Producing a workpiece typically involves a sequence of interpolation and fast traverse. This is clearly evident in drilling patterns, for example.

AJET recognizes these different phases and switches between the parameters for precision and maximum acceleration. By automatically switching between operating parameters, a machine achieves the best possible quality during the machining phase and superior productivity during the positioning phase.

The latest software version 4.7 for the Sinumerik Operate also includes machine optimizations, such as improved friction compensation. Friction between materials occurs in every machine tool and has a negative effect on contour accuracy.

Today every Sinumerik includes friction compensation for just this reason, thereby proactively compensating for contouring errors due to static or sliding friction. With the latest software version 4.7, Sinumerik 840D sl and Sinumerik 828D also offer new speed-dependent compensation for friction, better eliminating friction-dependent path deviations. This ensures consistently high contour accuracy and workpiece precision. Guided masks perfectly support initial operation.
