# Description

## General approach

The first step towards use of Volumetric Compensation consists of measuring the machine to determine the parameters for the machine model. There are several vendors of appropriate hardware and software on the market. The ISG controller supports:

- ISG CSV format
- Etalon® Exchange Format (see Section “File formats supported”).

After measurement, the parameters are available in one or more file(s). These parameter files can be loaded to the ISG kernel via a file interface. Volumetric Compensation is configured via the start-up list and the axis parameter lists.

Volumetric Compensation can be

- activated
- deactivated
- by a CNC programming command and the parameter files can be read in again.
