“…Acoustic emission is a phenomenon which occurs when, for different reasons, a small surface displacement of a material surface is produced [32]. This occurs due to stress waves generated when there is a rapid release of energy in a material, or on its surface.…”

“…The broad band sensor was used for finding the best frequency range for further investigation. Also in [32] acoustic emission was recorded in a broad band from 100 to 1000 kHz in order to monitor tool wear.…”

“…drilling one hole does not usually last very long. In addition it is possible to recognize certain stages in drilling when monitoring is practical [32]. Usually in the process the drill first touches the work material and thereafter progressively drills it, with a given penetration rate.…”

“…Naturally, the measuring signals vary as a function of the drilling stage. In [32] the transient drilling stage (when the drill starts to penetrate into the workpiece) and the stage when the drill is stopping were found to be the best moments to monitor tool wear using the envelope value of acoustic emission.…”

This paper presents a summary of the monitoring methods, signal analysis and diagnostic techniques for tool wear and failure monitoring in drilling that have been tested and reported in the literature. The paper covers only indirect monitoring methods such as force, vibration and current measurements, i.e. direct monitoring methods based on dimensional measurement etc. are not included. Signal analysis techniques cover all the methods that have been used with indirect measurements including e.g. statistical parameters and Fast Fourier and Wavelet Transform. Only a limited number of automatic diagnostic tools have been developed for diagnosis of the condition of the tool in drilling. All of these rather diverse approaches that have been available are covered in this study. In the reported material there are both success stories and also those that have not been so successful. Only in a few of the papers have attempts been made to compare the chosen approach with other methods. Many of the papers only present one approach and unfortunately quite often the test material of the study is limited especially in what comes to the cutting process parameter variation, i.e. variation of cutting speed, feed rate, drill diameter and material and also workpiece material. 

This paper presents a review of the state-of-the-art in sensors and signal processing methodologies used for tool condition monitoring (TCM) systems in industrial machining applications. The paper focuses on the technologies used in monitoring conventional cutting operations, including drilling, turning, end milling and face milling, and presents important findings related to each of these fields. Unlike existing reviews, which categorize results according to the methodology used, this paper presents results organized according to the type of machining operation carried out. By extensively reviewing and categorizing over one hundred important papers and articles, this paper is able to identify and comment on trends in TCM research, and to identify potential weaknesses in certain areas. The paper concludes with a list of recommendations for future research based on the trends and successful results observed, thus facilitating the cross-fertilization of ideas and techniques within the field of TCM research.
