“…Elbestawi et al [12] investigated the surface finish obtained after high-speed milling AISI H13 hot-work die steel hardened to 45 and 55 HRC. PCBN inserts with high and low CBN content were brazed on solid carbide ball-nose endmills with different edge preparations.…”

“…As far as the tool material is concerned, see Figure 4.5 (b), slightly lower deviation was produced by the cermet, probably due to its superior wear resistance. A geometric error of 25 µm was observed by [12] after high-speed milling hardened hot-work die steel using PCBN inserts brazed on solid carbide ball-nose endmills. As tool wear progressed, the error increased to 75 µm.…”

Surface integrity comprises the study of the alterations induced during the manufacture of a component that might affect its properties and service performance. Therefore, additionally to geometric irregularities (surface texture and both dimensional and geometric deviations), the study on surface alterations (such as metallurgical alterations, cracks and residual stresses) induced by hard-part machining is of utmost importance, especially in the case of components subjected to dynamic loading. Consequently, this chapter is focused on the investigation of the influence of tool material and geometry and cutting parameters on the surface integrity of components subjected to hard-part machining and, when applicable, comparisons are drawn with grinding and non-conventional processes, especially electrical discharge machining (EDM). Geometric IrregularitiesOwing to the fact that in most cases hard-part machining is employed as an alternative to grinding, the requirements concerned with surface texture (microgeomet-__________________________________ A.M.

The investigation of the chip behaviour during the end milling cutting process

Abstract. Generally the study, evaluation and general understanding of end milling cutters are complicated by the complexity of the cutting process and of the cutting tool. The main performance factor of the end milling cutters is given by the durability of the tool. In practice the sound analysis of the tool engaged in the cutting process is used as a simple predictability mean to forecast the future durability of the tool. An alternative or complementary tool to predict future durability is the investigation of the chip behaviour. Chip behaviour investigations can also give clues concerning the possible improvement of the cutting tools. The current article presents a detailed chip behaviour investigation for 5-fluted end milling cutters with different performances and various geometries when approaching different types of metal cutting operations in 42CrMo4 alloy steel. Current study can be applied in future researches regarding the evaluation and the development of end milling cutters. Furthermore the current approach can be used on other types of cutting tools.
