“…Flank wear occurs at the interface of the freshly generated workpiece surface and the tool's flank face under the significant influence of friction at the interface [122]. Flank wear due to abrasion was considered as the predominant wear mechanism on sintered carbide tools [114].…”

Carbon fiber reinforced plastieslpolymers (CERPs) offer excellent mechanical properties that lead to enhanced functionat performance and, in turn, wide apptications in numerous industrial fietds. Post machining of CERPs is an essential procedure that assures that the manufactured components meet their dimensional tolerances, surface quality and other functional requirements, which is currently considered an extremely difficutt process due to the highly nonlinear, inhomogeneous, and abrasive nature of CERPs. In this paper, a comprehensive literature review on machining of CERPs is given with a focus on five main issues including conventionat and unconventional hybrid processes for CERP machining, cutting theories and thermatlmechanical response studies, numerical simulations, tool performance and tooting techniques, and economic impacts of CERP machining. Given the similarities in the experimental and theoretical studies retated to the machining of gtass fiber reinforced polymers (GERPs) and other ERPsparaltet insights are drawn to CERP machining to offer additionat understanding of on-going and promising attempts in CERP machining.

“…These were 0.2, 0.4 and 0.6 mm. The wear land sizes were selected according to ISO3685 [19] and some were higher than the recommended value in order to study the force pattern for tool condition monitoring in future investigations. Thus a total of 144 tests with 4 specially made tool holders and 16 inserts were conducted.…”

Predictive force models for oblique metal cutting incorporating tool flank wear was carried out using a CNC lathe machine to turn mild carbon steel CS1030. The developed models are based on the fundamental mechanics of orthogonal cutting process, in which inclination angle is 0°. Workpieces were Cylindrical with wall thickness of 3mm and diameter of 100 mm. Cut thickness levels were 0.1, 0.17, 0.24 and 0.31 mm; cutting speeds were 100, 150 and 200 m/min; tool rake angle levels were −5, 0 and 5°. wearland sizes were selected as 0, 0.2, 0.4, 0.6 mm, where wearland size "0 mm" represents sharp tool. Results of the study indicate that tool flank wear has significant effect on oblique cutting forces. The oblique cutting forces were found to increase linearly with tool flank wear due to rubbing or ploughing forces in the wearland. The results also show that, the measured experimental oblique forces (power force, Fcm thrust force Ftm and rubbing force Frm) agreed with the predicted (power force Fc thrust force Ft,and rubbing force Fr) values under the corresponding cutting conditions. It is evident from the plots that the models give an excellent prediction of the cutting forces during oblique cutting.

“…Since the life of the tool depends on the frictional wear, which can be evaluated by measuring the radius of the cutting edge r, it was assumed that higher friction force will cause faster wear and will shorten the tool life. This assumption was made based on [37], who reported that increased flank wear results in the increased area of contact and increased coefficient of friction and presented the flank wear modelling method based on the friction.…”

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.
