The mechanical actions measurement can highlight a series of mechanical phenomena occurring in the cutting process. During the experiments, we use a six-component dynamometer to measured the forces and the moments applied by the tool to the workpiece. In this paper, the authors present a method for determining the cutting tool position in drilling process, with purpose to transport of the moments (calculation of the torsor in each of the holes). Then can be achieved analyze of the forces and moments for every hole.

Titanium and its alloys have found wide application in the aerospace, biomedical and automotive industries owing to their good strength-to weight ratio and high corrosion resistance. However, these alloys have very poor machinability, which is attributed to their inherent high strength maintained at elevated temperature and low thermal conductivity leading to high cutting temperatures. This paper presents the findings of an experimental investigation into the effects of cutting speed, feed rate and depth of cut when milling titanium alloy Ti-6Al-4V. The cutting forces were the response variables investigated. This experimental investigation is translated into a mathematical model of cutting forces designed on the basis of the results obtained from this research.

Vibration analysis has long been used for detection and identification of the machine tool dynamic condition. Predictive maintenance is directed towards recognizing the earliest significant changes in machinery condition. In contrast with the protective condition monitoring in which fast response is the primary requirement, predictive monitoring is not limited by time and may use a greater range of complex characteristics. The main focus is to identify a procedure in order to obtain natural frequencies values for the machine tool spindle using tracking dynamic analysis.

The object of this work research tasks relates to the improvement of the cutting tools in drilling within the industrial framework of the aeronautical assembly. The stakes of the study consist in optimizing the lifespan of the tools according to a criterion of respect of geometrical quality and surface quality of the bored holes. This optimization relates to the geometry of the cutting part of the drills. The discussion thread of work thus tends to set up methods which make it possible to bind the geometry of the tools to the final quality of borings carried out. The study was divided into three stages differentiated and complementary to modeling of the physical phenomena induced by the process of drilling. The first stage [1] lies in describing the real geometrical parameters according to the parameters of grinding of the tool. While being based on the modeling of the geometry, the experimental cutting model enables to identify the mechanical actions of cut along the edge. Lastly, the phenomenological [2] aspect of the process associates the parameters of cut the final quality of the bored holes. [3].
