In today’s production, the overall technical aim of a monitoring and control system is to introduce robust manufacturing with maximum performance. Generating targeted values means to transfer production know-how to the application of monitoring and control strategies, whereas such systems include a decisive potential for increasing added value in production companies. Especially in complex processes, important operational sequences should be analyzed and optimized online by means of system analysis and control. This paper reviews certain aspects and introduces recent investigations on process monitoring and control strategies for milling, drilling and broaching operations.
