The machining which consists of taking off chips remains the most important manufacturing process. In a machining unit, direct costs can reach between 10 and 15% of the running costs. The control of machining, and therefore, the quality of the thermal part, results of a sharp definition of the cutting conditions.


Due to this and also to the increase of machining of expensive parts, the need for a protection of the numerically controlled machine tool against machine breakage and wear has become a priority over the past few years. The problem has been solved thanks to the development and use of cutting Tool Monitoring Systems (TMS)
