Application of multi-sensor measurement system for machining process monitoring – a case study for sequential turning and burnishing processes

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.

KEYWORDS: machining process, measurement system, signal processing, monitoring, process optimization

STRESZCZENIE: W artykule przedstawiono budowę i funkcje eksploatacyjne układu pomiarowego, który został zainstalowany na 3-osiowej tokarce CNC w celu monitorowania i optymalizacji procesu skrawania. System rejestruje sygnały składowych wypadkowej siły skrawania, sygnały przyspieszenia (drgania skrawania) oraz sygnały siły EFM generowane dla różnych zastosowanych warunków obróbki. W rezultacie określono całkowitą pobieraną moc. Wygenerowane dane zostały zarchiwizowane w systemie ekspertowym, który wspiera optymalizację procesu cięcia pod kątem różnych kryteriów optymalizacji, w tym poboru mocy / energii.

SŁOWA KLUCZOWE: proces obróbki, system pomiarowy, przetwarzanie sygnałów, monitoring, optymalizacja procesów
