In a previous research work, a no contact capacitive sensor was obtained which could check superficial characteristics of workpieces during working. This sensor can relate variations of capacity to superficial finishing of the workpiece directly. The present study aims at finding a method for interfacing the capacitive sensor to a system of data acquisition and for deciding the substitution of the tool, automatically. It has been necessary to value the influence of cutting parameters on sensor's response in order to find the threshold value, characterizing by itself an anomalous working state owed to regular or irregular tool wear. © 1998 Elsevier Science Ltd.

Abstract
In a previous research work, a no contact capacitive sensor was obtained which could check superficial characteristics of workpieces during working. This sensor can relate variations of capacity to superficial finishing of the workpiece directly. The present study aims at finding a method for interfacing the capacitive sensor to a system of data acquisition and for deciding the substitution of the tool, automatically. It has been necessary to value the influence of cutting parameters on sensor's response in order to find the threshold value, characterizing by itself an anomalous working state owed to regular or irregular tool wear. © 1998 Elsevier Science Ltd.
