ACP Machinery’s findings on Volumetric Compensation conducted at Rambaudi S.p.A. (ITALY):

What is Volumetric Accuracy?

Volumetric accuracy is a function of all the machine tool geometric error components throughout the entire working volume.

Because it considers the whole volume, volumetric accuracy is a more detailed approach than volumetric error indicators such as the diagonal test specified in ISO 230-6.

Volumetric error at any point in the working volume is calculated, using a set of rigid-body equations, as a function of the measured geometric errors and axis position.

The volumetric accuracy is the worst of the volumetric errors.

In simple terms, if volumetric accuracy < component tolerance the machine tool is capable of producing the part.
