“…Nevertheless, if we consider that the peak value of the perforation force is crucial information in the punch optimization, we can consider the presented model as useful enough. This approach was previously presented in [2,3] and the obtained results have proved that considering the composite as an equivalent homogenous material in FEM analyses may be used in this application and it was supported with multiple examples found in scientific literature [23][24][25][26][27][28][29][30][31]. However, using only FEM analyses may give some false results connected with the mesh or poorly chosen failure parameters, which is why authors used a combination of both methods of research in which the experimental tests results are used for model verification.…”

Punch optimization is important in improving the technological process of belt perforation. Research about this process can rarely be found in the scientific literature. The objective of this paper is to determine the effective geometry of the piercing punches with a spherical bowl used for polymer composite belts. In order to fulfill this goal, the complex research of the influence of the geometrical features of the piercing punch on the perforation force, the hole quality, and the tool life has been conducted. For derivation of the proposed model, the authors have used the combination of analytical and FEM analyses, along with the experimental tests validation. Based on the results, there are clear correlations between the depth of the spherical bowl punch and the perforation force or the hole diameter deviation. By analyzing the ratio of the perforation and transverse force, we are able to evaluate how the tool life will change for different sets of geometrical parameters. All these correlations have been used to derive the indicators of the perforation force, tool life, and hole quality. Based on those, the optimization function has been specified. Finding the minimum value of this function makes it possible to define the optimal tool geometry. The design of effective tools for belt perforation with diameters D = 5, 6, 8, and 10 mm has been presented, but the obtained characteristic makes it possible to find an optimal solution for any diameter which lays in the range from 3 to 10 mm. Since the model has been built based on the indicators, it is easy to adjust it to match any specific requirements of the belt manufacturers, which makes it useful for tool designers.

This paper presents a simulation-based study of ultra-precision turning of hard-to-cut stainless steel 316L. In particular, Finite Element modeling was implemented to simulate the chipping process of stainless steel 316L under restricted process parameters. The aim of this investigation was to understand the underlying cutting phenomena under precise conditions. The simulation outcomes were validated by experimental results that were obtained by the authors in preceding work. A good agreement between both results was found which confirmed the initial hypothesis that FEM is a reliable means to simulate the cutting process accurately and thus to identify the optimum cutting conditions for the best possible performance of the process. The simulation results revealed that the minimum chip thickness of stainless steel 316L was determined to be 69%-75% of the cutting edge radius of the tool.

“…One major division of MMC is aluminumalloy matrix composite with ceramics particulate reinforcement such as silicon carbide (SiC) and alumina [1][2][3] . SiCp/Al composites, as one kind of ceramics particulate reinforced aluminum-alloy matrix composite, are more widely used in the aerospace, defense and automobile industries today, particularly in various engine components as well as brake rotors [4][5][6][7] .…”

An attempt was made to investigate the machinability of SiCp/Al composites based on the experimental study using mill-grinding processing method. The experiments were carried out on a high-speed CNC machining center using integrated abrasive cutting tool. The effects of combined machining parameters, e g, cutting speed (v s ), feed rate (v f ), and depth of cut (a p ), with the same change of material removal rate (MRR) on the mill-grinding force and surface roughness (Ra) were investigated. The formation mechanism of typical machined surface defects was analyzed by SEM. The experimental results reveal that with the same change of material removal rate, lower mill-grinding force values can be gained by increasing depth of cut and feed rate simultaneously at higher cutting speed. With the same change of MRR value, lower surface roughness values can be gained by increasing the feed rate at higher cutting speed, rather than just increasing the depth of cut, or increasing the feed rate and depth of cut simultaneously. The machined surface of SiCp/Al composites reveals typical defects which can infl uence surface integrity.
