Description

Due to a physical deformation of the tool (e.g. the erosion wire), the resulting contour may deviate from the programmed contour. To compensate for this error, Dynamic Contour Control (DCC) modifies the interpolated tool centre point path as a function of the current and previous contour elements, the tool parameters and an online influence of the PLC (e.g. velocity dependency).

The operating principle of Dynamic Contour Control is shown below:
The task of contour control is to influence the nominal contour by suitably modifying it so that the real actual contour corresponds to the programmed nominal contour.

Description 1:
Geometric mode of operation of programmed and corrected path
Description 2:
Arrangement of Dynamic Contour Control within the system

With a TcCOM object with instance-specific variables, the object must be configured in the respective CNC channel.

The function is defined either with P-CHAN-00385 or in the NC command #DCC[CALL=..].
