“…The result demonstrates that Cu:CuCNx multilayered composite coating improved the damping capacity of cutting tool under practical machining conditions. The similar improvement was also realized by Vladimir A. Rogov et al [24] They observed that a shim made of epoxy granite material, the magnitude value of FRF was adequately reduced compared with a standard shim.…”

The paper present theoretical and experimental studies of the energy dissipation performance of a composite structure composed in a multilayer nano-composite damping coating applied on a tungsten carbide shim and placed beneath the cutting insert. The coated shim placed closed to the cutting zone is subjected to high compressive and shear stresses as well as high temperature. Therefore, apart from high damping capacity it requires high stiffness and high thermal resistance. The coated shim dissipates the high frequency oscillations produced at the tool-chip and tool-workpiece interfaces during the chip forming process. The use of coated shims demonstrates that the tool life is considerably extended, while the machined surface integrity is improved. The Reuss model of the composite structure composed of a phase with a stiff, low loss factor and a phase with high loss factor is used to calculate the optimal coating thickness that gives high loss factor combined with high stiffness. The synthesis process of the coating material using HiPIMS process is discussed. The physical characteristics of the coating and the machining performance are presented in the experimental section.

“…The ANSYS workbench was used for computational analysis (FEA), and the calculated damping ratio was validated by experimental analysis for decreasing chatter by examining the operational and stationary properties of the cutting tools. Rogov et al (2017) examined the quality of the visible machine work and the effectiveness of the turning employing a shim by adding great restraint characteristics in the fastening of the insert. There are 5 planned shims, which will be prepared of granite, ceramic, chlorite schist, epoxy granite, and sandstone (Rogov et al, 2017).…”

This paper presents the concept, design and development of shim (passive damper) to improve the stability for high spindle speed machine operation of face mill tool. The objective of this paper is to learning the dynamic behavior of a face mill tool on VMC with dissimilar types of shims which cover investigation of dynamic motion behavior of the face mill tool, the behavior of different types of shim design and behavior of vibration by using the amplitude ratio method and analysis by a Design Expert. Research work supported computational analysis with Ansys, 35 VMC experimental records and analyzed by ANOVA/Design Expert with different type of shims to observe a dynamic behavior of chatter. It include of the effect of process parameters like Cutting speed (250,200,150 m/min), feed per tooth (0.05, 0.1, 0.15mm/tooth), depth of cut (1.2 mm, 1.0 mm, 0.8 mm), and different types of materials (shims) for face mill tool on VMC, for analyzing the responses like amplitude ratio in X – direction, Y- direction with ANOVA and optimizing for AISI 2062 steel by Design Expert. An experimental methodology was developed using the DOE (Design of experiment) technique. The optimum factorial method was used to design an orthogonal array of four factors having three levels. Here, the main results are based on amplitude ratio, ANOVA analysis and optimization. ANOVA was used to decide the effects of the machining parameters on the vibration amplitude ratio in X; and vibration amplitude ratio in Y. This is useful for evaluating the stability of milling operations via time domain FFT and analyzed by ANOVA. Data are validated by 35 sets of VMC experiments. Physical 35 experiments may be not enough in a view of high level researchers, academicians and industrialist to conclude the use of shim and it need in face mill tool on VMC. Hence here optimization based on optimum factorial method is executed using Design Expert software in which 35experiments and its iterations with 70 populations were used to run the program. It is found that the most critical parameter in this study is the material of Shim. At high cutting parameters carbide shim, at low and medium cutting parameters SS shim are given better results by ANOVA and Optimization of Design Expert also validated by 35 sets of VMC experiments. Hence these shim designs endorse versatile solutions.

Pocket milling is a common task in manufacturing of aeronautical or space use parts, but also for molds and dies. This process is time-consuming and has an important impact on the cost of the final product. For this paper, among all the possible directions of 2D1/2 pocketing improvement, the optimization of toolpath geometry has been chosen. Most of time, the toolpaths are computed from a Computer Aided Manufacturing software using classical tool trajectories such as "zig-zag" or "contour parallel". These trajectories show discontinuities or local high curvature, creating frequent stop and go of the tool. These toolpaths are, fundamentally, not efficient in High Speed Milling. Some authors and software designers proposed methods to tackle those problems by local modification of the toolpath to improve his higher order continuity. Others, like M. Bieterman, build directly a C2 spiral tool path with low curvature (this strategy propose to solve numerically a 2D Partial Differential Equation problem and to use the iso-curves as structure curves to build the spiral). These strategies are efficient for High Speed Milling but leads to much longer toolpaths, so it can't be necessarily a beneficial way. The goal of this paper is to compare, for 2D1/2 pocket roughing, the time performance of different machining strategies: "zig-zag", "contour parallel", morph spiral and "Bieterman" used on different homothetic rectangular pockets. For this purpose, VPOp software developed in the LURPA Lab from Cachan is used. With this procedure, it will be possible to see, for which ratios of size, a milling strategy is efficient or not.
