Process and Energy Data Acquisition on Machining Center and Individual Machine Components

Abstract

This paper describes possibilities of process and condition data acquisition on universal milling centers with Sinumerik 840D-sl control. The measurement and process data is gathered mostly with the present control system architecture of the machine tool. This internal data collection has been extended by additional sensors and an external measurement system to enable further and partially deeper analysis. This setup is also explained in this publication. The demonstrator together with the measuring system allows an investigation of the introduced components close to reality and the observation of the overall system at once. The latter is considered energetically on a comparative measurement to ascertain discrepancies in energy consumption between two different milling strategies for a pocket cycle.
