TF5280 | TwinCAT 3 CNC Volumetric Compensation

TwinCAT 3 CNC Volumetric Compensation is an optional package for compensating geometric machine errors based on an ISO-standardized parametric model.

Application

• highly effective option for increasing the machine accuracy and therefore the manufacturing accuracy, simply through control measures
• correction of the TCP position through dynamic calculation of axis correction values
• suitable for machines with 3 Cartesian and up to 3 rotary axes
• any kinematic axis order (head/table kinematics)

Features

• several parameter files per compensation, several compensations per controller
• parameter update via NC command or HMI
• interpolation of parameter sets (sag compensation, etc.)
• smoothing of parameter step changes during modulo transitions
• diagnostics possible via ADS, Microsoft Excel file

Safety

• configurable limitation of the compensating values
• configurable limitation of the travel-out velocity of the compensating values

Supported file formats

• tabular CSV format
• Etalon exchange format

Standards

• DIN ISO 230 “Test code for machine tools”
• ISO/TR 16907 “Machine tools – Numerical compensation of geometric errors”
