“…And now Zeroudi et al [16] have integered in model the use of CAM tool paths and Zeroudi and Fontaine [17] have also predicted the produced form and roughness. More recently finite elements models have been extended to milling process but only few detailed experimental research are available in literature : Shao et al [18] proposed a machinability study on 3%Co-12%Cr stainless steel in milling and D'Errico et al [19] studied the tool-life reliability of cermet inserts with milling tests. In the FEMTO-ST Institute, a 3D finite element model of milling has been developped with the commercial software LS-Dyna by Maurel-Pantel et al [20].…”

Last years analytical or finite element models of milling become more efficient and focus on more physical aspects, nevertheless the milling process is still experimentally unknown on a wide range of use. This paper propose to analyse with accuracy milling operations by investigating the cutting forces values, shape of cutting forces curves obtained for different cutting speeds, and related phenomena as tool wear or tool run-out. These detailed experimental data in milling constitute a suitable experimental basis available to develop predictive machining modelling. All the tests have been conducted on the 304L stainless steel in many cutting configurations and for different tool geometries. The machinability of the 304L stainless steel with different tools geometries and configurations in shoulder milling is defined by three working zones: a conventional zone permitting stable cutting (low cutting speed; under 200-250 m.min -1 ), a dead zone (unfavourable for cutting forces level and cutting stability; between 250 and 450 m.min -1 ), and a high speed machining zone (high cutting speed; up to 450-500 m.min -1 ). All the used criteria (cutting forces, chips, wear) confirm the existence of these different zones and a correlation is proposed with cutting perturbations as run-out, cutting instability, ploughing and abrasive wear.

Ti(C,N) solid solutions in hot-pressed Ti(C x N 1-x ) (x=0.0, 0.3, 0.5, 0.7, 1.0) and 40TiC-40TiN-20Ni (in wt.%) cermet were characterized in this study. For hot-pressed Ti(C,N)s, the lattice parameters and hardness values of Ti(C,N) were determined by using XRD (X-Ray Diffraction) and nanoindentation. The properties of hot-pressed Ti(C,N) samples changed linearly with their carbon or nitrogen contents. For the TiC-TiN-Ni cermet, the hardness of the hard phase and binder phase were determined by nanoindentation in conjunction with microstructural observation. The measured hardness values were ~8.7 GPa for the binder phase and ~28.7 GPa for the hard phase, which was close to the hardness of hot-pressed Ti(C 0.7 N 0.3 ).

The indentation technique has been one of the most commonly used techniques for the measurement of the mechanical properties of materials due to its experimental ease and speed. Recently, the scope of indentation has been enlarged down to the nanometer range through the development of instrumentations capable of continuously measuring load and displacement. In addition to testing hardness, the elastic modulus of submicron area could be measured from an indentation load-displacement (P-h) curve. In this study, the hardness values of the constituent phases in Ti(C 0.7 N 0.3 )-NbC-Ni cermets were evaluated by nanoindentation. SEM observation of the indented surface was indispensable in order to separate the hardness of each constituent phase since the Ti(C 0.7 N 0.3 )-based cermets have relatively inhomogeneous microstructure. The measured values of hardness using nanoindentation were ~20 GPa for hard phase and ~10 GPa for binder phase. The effect of NbC addition on hardness was not obvious in this work.
