CNC performance

Always achieve the maximum CNC performance

Productivity, precision, availability, costs – these are the decisive driving factors in the machine tool market. Packed with special functions, SINUMERIK controls precisely satisfy these requirements – for a high level of CNC performance.

Wide-ranging possibilities to achieve high productivity

Robot integration, intelligent motion control as well as continuous optimization are the relevant buzz words when it comes to leveraging the wide-ranging possibilities of boosting productivity.

• All facets of robot integration
  The demand for automation solutions for machine tools teamed up with high precision industrial robots is increasing at a rapid pace. This applies equally to handling – as well as high-precision and complex machining tasks. With SINUMERIK, Siemens has a CNC system for robot integration: From a simple connection via the user-friendly integration for handling tasks – up to the complete integration of robot kinematics in a system.
• Intelligent motion control
  SINUMERIK provides an optimal workpiece surface at maximum milling speed with the intelligent Advanced Surface and Top Surface motion control features.
• Continuous optimization
  Maximum dynamic performance and precision of machine axes are achieved using the Auto Servo Tuning (AST) functionality of SINUMERIK Operate, which allows control parameters to be automatically optimized. This simplifies commissioning the machine, and in operation, the machine can be regularly optimized using AST. This ensures maximum machine precision over the entire lifecycle.

Precision in production

One way the SINUMERIK precision is achieved is due to the compensation of mechanical effects via the software. This includes functions such as 80-bit NANO, friction compensation and nodding compensation.

• Accuracy
  SINUMERIK CNCs and SINAMICS drives perform calculations with powerful 80-bit NANO accuracy. This eliminates rounding errors and provides extremely high internal computing accuracy in the entire control chain.
• Nodding compensation
  Nodding compensation is used to compensate dynamic position deviations due to acceleration operations in machine axes. As a result, improved machining quality with simultaneously higher jerk and acceleration values is achieved.
• Friction compensation
  Friction-related path errors are even more effectively eliminated by compensating the effects of friction as a function of the velocity. This allows a consistently high contour accuracy and workpiece precision to be achieved.
• Volumetric compensation (VCS)
  VCS enables compensation of geometric deviations of linear as well as rotary axes in their effect on the tool center point. Higher machining accuracy is the direct consequence.

Increasing availability

Condition monitoring and collision avoidance ensure high availability of the machine tool.

• Collision Avoidance
  Provides optimum collision protection: Collision Avoidance in SINUMERIK offers 3D collision monitoring in real time – for 1-channel machines with one NCU – and also for complex machining operations such as 5-axis simultaneous milling. Collision detection is available in all operating modes (JOG, MDi and Automatic). The motion of machine elements with respect to one another and the tool is visualized in 3D in SINUMERIK Operate.
• Condition monitoring
  With SINUMERIK condition monitoring, information about the machine condition is evaluated and the status acquired using machine fingerprints. The direct result is a valid statement about the machine quality and possible hidden deficiencies.

Lower operating costs

Operating costs can be reduced using energy-efficient solutions over the entire life cycle of the machine.

• SINUMERIK Ctrl-Energy
  SINUMERIK Ctrl-Energy covers a wide range of highly efficient drive/motor components, CNC/drive functions, software solutions, and services. For example, the user has access to intelligent functions that allow analysis of the energy costs for each workpiece. Pressing the Ctrl+E shortcut helps the SINUMERIK to save energy in the long term.

Increasing security

Safeguarding intellectual property in the program code and protection against manipulation by malware are two important aspects in the system integrity of SINUMERIK.

• Know-how protection
  The SINUMERIK function Lock MyCycles is used to store user cycles in the control as protected data. The SIMATIC STEP 7 program blocks are also protected by a password, thus ensuring confidentiality of user know-how.
• Security
  PC-based systems and the control level must be protected against cyber attacks. The use of antivirus and whitelisting software provides manipulation protection and prevents malware from affecting PC-based systems.
