Complex tasks – new solutions

TwinCAT CNC offers complete CNC functionality as a pure PC-based software solution. TwinCAT CNC covers the complete range of classic CNC path control, including high-end systems for complex motion and kinematics requirements. The powerful, continuously evolving PC platform and the hard real-time base of the TwinCAT realtime kernel provide the foundation for the CNC software.

 

TwinCAT continuity

TwinCAT CNC is based on TwinCAT PLC, the IEC 61131-3 software PLC. If TwinCAT NC PTP is used as the basis; powerful motion functionality for positioning tasks is also available. Parts programming is carried out according to DIN 66025 using high-level language extensions. TwinCAT CNC expanded TwinCAT NC I with classic CNC features. Up to 64 interpolating axes and comprehensive coordinate and kinematic transformations are possible.

 

Open for I/O and drive systems

In the CNC world, TwinCAT CNC offers unique openness towards the I/O periphery and the drive system through the consistent utilisation of Fieldbus technology. A variety of I/O modules can be connected via all common fieldbus systems. The drive systems can be connected with the CNC via an analog/encoder interface or directly via a digital drive interface (e.g. EtherCAT, PROFIBUS DP/MC, SERCOS or Lightbus). This offers maximum openness and independence in the choice of I/O and drive systems for the user.

 

Versatile machining

The required axis and spindle functions, interpolation and feed functions, tool and help functions according to DIN 66025 with specific expansions are available for a variety of machining technologies (e.g. milling, drilling, handling, special machines).

 

Interpolation with 64 axes

Complex machining tasks often require path movements involving a large number of axes and spindles. TwinCAT CNC can operate with 64 axes/controlled spindles that can be distributed across up to 12 CNC channels. In a CNC channel, up to 32 axes can be interpolated simultaneously, enabling even the most difficult motion tasks to be solved.

 

HSC technology (high-speed cutting)

Advanced HSC cutting technology requires CNC control technology with optimised solutions for Motion Control in order to achieve optimum results in terms of processing time while at the same time offering maximum accuracy and workpiece surface quality.

The TwinCAT CNC HSC pack offers the following options:

 

Real-time transformations

Complex machine kinematics with difficult machining tasks require real-time transformations within the CNC for simple and flexible operation and programming. They are used, for example, for defining different coordinate systems within the machining process or for generating automatic compensating movements of rotary axes. A classic application is 5-axis machining.

As an option, TwinCAT CNC provides special CNC functions for this:
