Abstract

In this paper, the structure and operational functions of a measurement system, which was installed on a 3-axis CNC lathe for monitoring and optimization of the cutting process are presented. In general, the system records signals of the components of the resultant cutting force, acceleration signals (cutting vibrations) and EFM force signals generated for various machining conditions employed. As a result, the total power consumed was determined. The generated data were archived in the expert system which supports the optimization of the cutting process in terms of various optimization criteria including power/energy consumption.

Highlights

  • It can be noticed that that the technological progress in the leading manufacturing sectors is growing continuously year by year

  • Authors of this paper did not find, after analysis of many measurement/monitoring systems dedicated to machining processes, a comprehensive solution for data collection directly from production in on-line mode, which can be subsequently analyzed according to the algorithm and generate optimal machining conditions regarding the demanded criteria

  • The information elements of the measurement system tested in this study were based on the measurement and data processing devices produced by National Instruments
