“…The influence of the feed per tooth f z and the cutting width a e on the uncut chip thickness is significantly higher, as it is exemplary shown in Figure 6(b). Similar tendencies can be found for the dependencies of the chip cross-section [11,19]. This shows the high potential of optimizing the technological cutting conditions along the whole tool path.…”

Advanced materials, like nickel-based alloys, gain importance in turbomachinery manufacturing, where creating complex surfaces constitute a major challenge. However, milling strategies that provide high material removal rates at acceptable tooling costs demand optimized tool geometry and process parameter selection. In this paper, a description of circular milling is given, focusing on resulting engagement conditions. Regarding this, a test bench was designed to investigate the chip formation process in an analogy milling process. Furthermore, the methodology for the approach in the analogy process was developed. Results of a first test run in Inconel 718 verify the presented approach.

“…Furthermore there are also papers, that describe the stresses during the machining [16][17][18], tool wear [19] and of course cutting forces [20][21][22][23]. In all these projects, there were utilised a number of softwares like Marc, Abaqus, Deform 2D/3D, Nike, AdvantEdge, etc.…”

In this chapter it is examined the use of finite elements in predicting the cutting forces of machined parts of stainless steel AISI 316 L through turning. The process used the high speed machining technique, which is continuously improved and it has be found application in more and more manufacturing processes like aerospace industry, in die and mold companies and in the last years also in bioengineering in manufacturing hip joint implants. The cutting forces, which were measured through experimental process, were compared with predicted ones from the finite element modulation, and it was exported that they can be predicted with good precision when machining with the FEM model.

“…In addition, tool wear can also be caused by an abrasive rather than by a thermally process, by considering its poor thermal conductivity, which leads to elevate the temperature at the rake face (Kitagawa et al, 1997).The minimum flank wear was observed when using the SNGN tools at low cutting speeds or the RNGN tools at high cutting speeds (Altin et al, 2007). In addition, cutting forces and different types of tool wear were reduced by increasing the feed rate when turning of Inconel 718 with ceramic tool (El-Wardany et al, 1996), this parameter is considered as the most relevant cutting parameter affecting ceramic tool stresses (Kose et al, 2008;Nalbant et al, 2007;Ezugwu & Tang, 1995;Gatto & Iuliano, 1997;Altin et al, 2007).…”

Inconel 718 is among difficult to machine materials because of its abrasiveness and high strength even at high temperature. This alloy is mainly used in aircraft and aerospace industries. Therefore, it is very important to reveal and evaluate cutting tools behavior during machining of this kind of alloy. The experimental study presented in this research work has been carried out in order to elucidate surface roughness and productivity mathematical models during turning of Inconel 718 superalloy (35 HRC) with SiC Whisker ceramic tool at various cutting parameters (depth of cut, feed rate, cutting speed and radius nose). A small central composite design (SCCD) including 16 basics runs replicated three times (48 runs), was adopted and graphically evaluated using Fraction of design space (FDS) graph, completed by a statistical analysis of variance (ANOVA). Mathematical models for surface roughness and productivity were developed and normality was improved using the Box-Cox transformation. Results show that surface roughness criterion Ra was mainly influenced by cutting speed, radius nose and feed rate, and that the depth of cut had major effect on productivity. Finally, ranges of optimized cutting conditions were proposed for serial industrial production. Industrial benefit was illustrated in terms of high surface quality accompanied with high productivity. Indeed, results show that the use of optimal cutting condition had an industrial benefit to 46.9 % as an improvement in surface quality Ra and 160.54 % in productivity MRR.
