# Overview

## Task

Oscillating axis motions (oscillation) are used for the grinding machining process, for example. As a result of the oscillating motion, a tool (grinding disc) moves in the reverse direction across the workpiece in order to reach the final dimension with high precision and surface quality.

## Characteristics

The essential characteristics of the oscillating motion result from the oscillating motion between two absolute positions as well as the feed rate.

## Parametrisation

Settings are required in the channel and axis parameter lists to parameterise an oscillating motion. The section Parameter contains a detailed description of the commands.

## Programming

An oscillating motion is defined in the NC program by the axis-specific command X[OSC…] (see Chapter Programming).
