	abstract = {Natural fiber-reinforced plastic (NFRP) composites are ecofriendly and biodegradable materials that offer tremendous ecological advantages while preserving unique structures and properties. Studies on using these natural fibers as alternatives to conventional synthetic fibers in fiber-reinforced materials have opened up possibilities for industrial applications, especially for sustainable manufacturing. However, critical issues reside in the machinability of such materials because of their multiscale structure and the randomness of the reinforcing elements distributed within the matrix basis. This paper reports a comprehensive investigation of the effect of microstructure heterogeneity on the resultant behaviors of cutting forces for NFRP machining. A convolutional neural network (CNN) links the microstructural reinforcing fibers and their impacts on changing the cutting forces (with an estimated R-squared value over 90%). Next, a model-agnostic explainable machine learning approach is implemented to decipher this CNN black-box model by discovering the underlying mechanisms of relating the reinforcing elements/fibers' microstructures. The presented xml approach extracts physical descriptors from the in-process monitoring microscopic images and finds the causality of the fibrous structures' heterogeneity to the resultant machining forces. The results suggest that, for the heterogeneous fibers, the tightly and evenly bounded fiber elements (i.e., with lower aspect ratio, lower eccentricity, and higher compactness) strengthen the material and thereafter play a significant role in increasing the cutting forces during NFRP machining. Therefore, the presented framework of the explainable machine learning approach opens an opportunity to discover the causality of material microstructures on the resultant process dynamics and accurately predict the cutting behaviors during material removal processes.},

	abstract = {Lightweight carbon fibre-reinforced polymer (CFRP) sandwich structures with honeycomb cores have excellent specific bending stiffness and good dimensional stability; therefore, their future applications will extend extensively, despite their difficult-to-manufacture nature. Although the drilling of single CFRP structures has been widely investigated, the published experience of drilling honeycomb cored CFRP sandwich panels is strongly limited. Therefore, the main objective of the present paper is to experimentally analyse the machinability of CFRP sandwich panels with filled and unfilled aramid Cormaster honeycomb cores through the analysis of thrust force, drilling torque and drilling-induced burrs. A twist and a brad and spur drill were used in two sandwich structures at three feed levels for the drilling experiments. The thrust force and drilling torque were measured by a KISTLER dynamometer, and the burrs were processed through digital image processing of optically captured images. The experimental results show that the application of fillers in the honeycomb only slightly decreases the nominal specific stiffness of the CFRP/honeycomb sandwich structures and slightly increases the thrust force; however, a significant improvement is achievable by their application in the drilling-induced burr formation of the honeycomb core.},

	abstract = {In CNC milling, the feed rate scheduling is a frequently used method to increase machining quality and efficiency. Among the benefits of feed rate scheduling, this paper focuses on controlling the tool load and optimizing the machining time. Although the advantages of feed rate scheduling are undeniable, some areas remain still to be addressed. In order to control the tool load, geometric methods are often used, which are based on keeping a specific parameter, such as chip thickness or material removal rate (MRR) constant. However, a high level of tool load control can only be provided if cutting force models or experimental-based techniques are used. Besides traditional methods, this paper presents an artificial neural network (ANN)-based feed rate scheduling method to keep the tool load constant, using data gained by preliminary cutting experiments. A case study demonstrates that a significantly higher level of tool load control can be achieved with this method as compared to the geometric models. Besides controlling the tool load, the present feed rate scheduling method also addresses the consideration of acceleration limits which is of great importance for practical uses. The application of feed rate scheduling in trochoidal milling is also discussed in detail in this paper. This area has not received enough attention, as due to the limited fluctuation of cutter engagement, the tool load was considered as well-controlled. However, experiments have shown that in the case of trochoidal milling, the introduction of feed rate scheduling can still further increase the machining efficiency. Using the developed ANN-based feed rate scheduling method, significant progress could be made as compared to conventional technologies in controlling the cutting force and optimizing the machining time. In the present case study, a reduction of 50% in machining time was achievable by adjusting the feed rate without increasing the peak value of cutting force.},

However, the accuracy of the prediction is largely affected by the dynamic characteristics of the machine tool system and tool wear. This paper proposes a prediction method of cutting force considering the influence of machine tool system and tool wear to improve the accuracy of the conversion from orthogonal cutting to milling. First, the machine tool correction coefficients are used to introduce the influence of machine tool system into the orthogonal cutting force prediction model. Then, the influence of the tool wear is taken into account by defining the tool wear coefficients. Finally, the accuracy of the cutting force obtained by the proposed method is verified through experimental research. The results show that the prediction results are in good agreement with the experimental results.},

This article summarizes the results of a project to study the cutting force during milling. The technological analysis of milling was performed by FEM simulation, which was validated by measuring the cutting force. When milling, only one insert was placed in the cutter, the workpiece was C45 rolled steel, which was machined with different depths of cut ap and feed rates fz while the cross section Ac = ap · fz = 0.9 mm2 was kept constant. The calculations proved that the effect of the cross-section of the material deposited during milling, and thus the specific features of the technology, is well characterized by the chip ratio ap/fz. It has been shown that from the energy point of view it is expedient to avoid the chip ratio of ap/fz = 1 in the applied technology. It is preferable to set the value as far away as possible, preferably aiming to use ap/fz < 1. © 2020 CIRP},

A new numerical model for broaching force with complex profile tools was presented, which considered the area and arc length of the curved shear zone boundary. The area and arc length were calculated by the curve function of the boundary, which is firstly predicted by FEM simulation. Then, an experimental device was set up to carry out the broaching experiment with straight profile tools and complex profile tools in accordance with the progressive depth of the cut. Based on the experiments, the traditional broaching model and the modified model with the complex profile tool have been established. Compared with the traditional force model, the accuracy of the modified model has been moderately improved. Furthermore, the modified main broaching force (Y direction) model and the normal force (Z direction) model show a significant improvement in accuracy of 4.8% and 9.7%, respectively, which suggests that the projection area of curved shear zone A(1) and the projection arc length of curved shear zone l(1) have a big impact on the broaching process. It is firmly believed that the modified model proposed in this paper can provide guidance for the design of complex profile tools and facilitate the efficient and high-precision machining of complex parts.},

	abstract = {Micro-milling is one of the most important technologies to produce miniature components. Mainly due to the size reduction, the process has many special characteristics, such as the relatively large tool run-out, the relatively large deformation and the cutting edge radius of the micro-milling tool. The cutting force is often correlated to the phenomena mentioned above, its analysis is therefore often required. The main objective of the present paper is to analyse and compare the characteristics of cutting forces in micro-milling of different hardened steels. A systematic series of experiments were conducted on a hardened AISI H13 hot-work tool steel and a Bohler M303 martensitic corrosion resistance steel. The hardness of both materials is 50 HRC. A 500 mu m diameter two fluted carbide micro end mill and a five-axis micromachining centre were applied. The effects of the cutting parameters are analysed by the analysis of variance (ANOVA). Experimental results show that the workpiece material has a significant influence on the cutting forces.},

The effect of the variation of the radial rake angle has not yet been discussed in the literature. As a novelty, this article investigates such an effect, especially the effect on chip thickness. A new tool model is proposed that takes into account the radial rake angle. A new method to calculate the chip thickness has been developed that uses the new tool model and is based on several existing numerical and approximation methods. It is analytically proved that the effect of the radial rake angle must be taken into account for calculating accurate results; however, in the case of lower feed rates, that effect is insignificant. The presented procedures are evaluated with respect to their accuracy and computing requirements. The proposed new methods have been verified by cutting experiments.},

The edge geometries of the so-called lag and helix variations are used in this paper, and their equivalency is established from engineering point of view. The equivalent relation is derived analytically and the nonlinear algebraic system is described, with which the numerical equivalency properties can be determined. The equivalent description can be utilized in variable helix tool production to determine an optimized set of geometrical parameters of the edge geometry. The stability properties are shown and compared for a simple one degree-of-freedom case with the nonuniform constant helix tools. The robustness of the results related to the harmonically varied tools is critically discussed in this paper showing advantages compared to the nonuniform constant helix case. The results suggest that the more extreme the edge variation is, the more stable the process performed with the corresponding harmonically varied tool becomes.},

	abstract = {Many applications are available for the syntactic and semantic verification of NC milling tool paths in simulation environments. However, these solutions - similar to the conventional tool path generation methods - are generally based on geometric considerations, and for that reason they cannot address varying cutting conditions. This paper introduces a new application of a simulation algorithm that is capable of producing all the necessary geometric information about the machining process in question for the purpose of further technological analysis. For performing such an analysis, an image space-based NC simulation algorithm is recommended, since in the case of complex tool paths it is impossible to provide an analytical description of the process of material removal. The information obtained from the simulation can be used not only for simple analyses, but also for optimisation purposes with a view to increasing machining efficiency.},

The location information of the cutter in the two orthogonal directions of the cutting plane was obtained by the real-time signal acquisition system. Meanwhile, the KISTLER sensor was installed on the tool head of the machine tool to measure the real-time cutting forces in three cutting directions. The experimental data shows that volatility change of the cutting force was produced in the feed direction with the displacement. In order to study the complex nonlinear relationship between the cutting force and cutting parameters, the prediction of dynamic cutting force is realized by time series analysis modeling. The cutting force error is analyzed, and the prediction accuracy obtained meets the requirements. © 2019, Editorial Department of Journal of Northeastern University. All right reserved.},

		tolerance shrink. This fact makes the appliance of precision-
		and micromachining operations required. Mechanical cutting has been successfully adapted to perform precision machining and microcutting with uncut chip thickness typically under 0.01 mm. Size effect is dominant in this scale: the amount of specific cutting energy greatly increases according the type of material deformation occurring at the cutting edge radius. The multi-sectioned empirical model of specific cutting force proved to be an effective model to indicate such transient mechanisms. Aim of current research is to describe the effect of cutting parameters on the known section borders (called boundary chip thicknesses) in the model of specific cutting force. As a result, the newly created empirical models involve feed rate and cutting speed as direct input parameters, and assumption has been made to explain the physical meaning behind boundary chip thicknesses from the
		aspect of material deformation.},
