How much energy does precision need?

A. Gontarz¹, R. Roth², T. Liebrich²

A machine tool mainly consumes electrical energy, but also hydraulic, thermal and pneumatic energy for specialized functions. The efficient use and correct control of these types of energy are crucial for the operation and performance of the machine tool are not rule-based but highly individual and dependent on the machine use, its configuration and parametrization, especially when high demands are placed on the accuracy of the manufactured workpieces.
This article presents the results of a multi-channel measurement in accordance with ISO 14955 on a 5-axis machining center. For this purpose, all energy forms and components in various operating states of the machine tool are systematically recorded and analyzed. The result is a detailed analysis of all system components in all operating states with a focus on process conditioning and the identification of inefficiencies. Based on the measurements carried out, nine measures are defined which have a usage-dependent optimization potential of up to 15 %.
