Overview

This document is a summary of the following three functionalities:

Task

Online tool radius compensation permits the integration of technology-specific tool compensation in real time. It is specially designed for EDM wire erosion with an inclined wire in 2-path applications.

Dynamic Contour Control (DCC) compensates for deviations between the programmed and the actually produced contour, for example, resulting from the physical deformations of an erosion wire. The aim is to adapt the actual contour to the nominal contour.

Geometric feed adaptation allows the user to influence the feed rate by using custom (geometry-dependent) algorithms. With EDM wire erosion, this is specially designed to ensure constant surface removal.

Properties

Online tool radius compensation: Only applies when tool radius compensation (G41/G42) is enabled. Requires a C2 continuous parallel path taken from static tool radius compensation. Supports 2-path configuration with independent dynamic planning and synchronised output.

Dynamic Contour Control: Modifies the interpolated tool centre path as a function of current and previous contour elements, tool parameters and PLC influence (e.g. velocity dependency).

Geometric feed adaptation: Calculates a factor that is multiplied by the current command velocity and the override factor. The calculation is based on a cyclically corrected radius centre point path where the tool radius consists of the actual tool radius and a gap value.

Programming

Mandatory note on references to other documents

For the sake of clarity, links to other documents and parameters are abbreviated, e.g. [PROG] for the Programming Manual or P-AXIS-00001 for an axis parameter.

For technical reasons, these links only function in the Online Help (HTML5, CHM) but not in pdf files since pdfs do not support cross-linking.
