Volumetric Error Compensation for the MScMS-II
AbstractLarge scale measuring systems, i.e. measuring systems characterized by a measurement volume from some meters up to some hundreds of meters, are gaining importance in industry to check large parts or track the position of automated vehicles.

Comparison of Volumetric Analysis Methods for Machine Tools with Rotary Axes [PDF]
Confidence in the ability of a production machine to meet manufacturing tolerances requires a full understanding of the accuracy of the machine. However, the definition of “the accuracy of the machine” is open to interpretation. Historically, this has

Fuzzy modeling of volumetric efficiency and specific energy consumption in agricultural screw conveyors [PDF]
: Vertical screw conveyors have low energy efficiency but this is generally acceptable within the normally low power range. Previously, a fuzzy logic approach was used to model volumetric efficiency and specific energy consumption in screw conveyors. The

The modeling method of machine tool geometry error based on Bryan principle
The error caused by measurement itself directly affects the accuracy of models. The error caused by the failure to follow the Bryan principle in the process of measuring the volumetric error of the machine tool makes the geometric accuracy of the machine
