Introduction

For specific machining technologies such as grinding, an oscillating axis movement is necessary which is executed largely independently of a contouring motion.

This motion referred to below as an "oscillating motion" is executed by the tool periodically reversing over the workpiece.

In the strict physical sense, the typical oscillating motion is sinusoidal. Therefore, when the term "oscillating motion" is used for the periodic reversing motion considered below, it is necessary to consider the fact that the timing of the motion is generally not sinusoidal. As the relative speed between the disk and the workpiece, at least during tool engagement, should be constant during typical grinding, this is also intentional.

An oscillating axis during grinding is presented below as an example. The workpiece is machined by superposition of the oscillating X motion with positioning motions in the Y and Z axes.
