	abstract = {Trochoidal milling is a widely used technique in high-speed machining. In the recent period, several theoretical and experimental studies have been performed to analyze the cutting process in trochoidal milling of slot-like geometries. However, these works typically focused only on cycloid- and circular-shaped trochoidal strategies and did not consider the possibilities of path shape optimization. This is because optimizing the trochoidal tool path is a double challenge: (1) modelling of material removal process is necessary to satisfy the geometrical and technological conditions, and (2) the relationship between tool path shape and machining efficiency is highly complex; therefore, direct optimization solutions cannot be applied.
		
		This paper presents a new Bézier curve-based tool path modelling technique and a new stochastic hill climbing algorithm-based optimization method to increase the efficiency of trochoidal strategy. During the tool path shape optimization, the limiting factors of cutter engagement and path curvature radius were also considered to meet the criteria of high-speed machining. The simulation experiments proved that the machining efficiency could be increased significantly by optimizing the trochoidal tool path by up to 40%, compared to the traditional cycloid strategy. The cutting experiments verified that the tool load remained well controlled, and productivity could be improved without increasing the tool load. The paper also discusses the appropriate settings to ensure the best functioning of the stochastic hill climbing algorithm. The industrial application of the developed algorithm can result in significant cost, energy and time savings for manufacturers when machining slot-like geometries.},

	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.},

	abstract = {In this scientific study, the authors have dealt with the slot milling of nickel-based superalloys. These alloys are among the most difficult materials to machine and are widely used in aerospace and energy industries. Due to the properties of the material, slot milling is a particular problem because tool wear happens quickly, and tool breakages are common. When these superalloys are machined, very high temperatures occur in the cutting zone, which cannot leave due to the extremely poor thermal conductivity of the material and will therefore transfer to the edges of the cutting tool, causing it to anneal, break off and fail. So, the researchers initiated a new field of research: cryogenically-assisted machining. In this paper, the authors used two cooling methods, the conventional flood cooling and cryogenic cooling with liquid carbon-dioxide (LCO2). The effects of these cooling methods were tested focusing on the cutting forces, tool wear, chip morphology and surface roughness of the bottom of the slots. The aim was to determine the best cooling methods for these materials. Based on the results, it can be concluded that, LCO2 has a negative effect on cutting forces, tool life and surface roughness. It only has a positive effect on chip formation. It can be see that, the lubricating effect has a greater impact on tool life, tool load and surface roughness of the milled slots than cooling.},

The true trochoidal toolpath has C2 continuity and avoids sharp changes in engagement angle and cutting load, resulting in smooth machine tool movement. However, its total length is too long, and its engagement angle is uneven. These factors limit further improvements in the material removal rate. Based on the true trochoidal toolpath model, this paper develops an ellipse-based trochoidal toolpath generation method by introducing a compression ratio in the trochoidal step direction. The analytical model of engagement angle and the mechanistic model of the cutting force are proposed. A series of simulations and milling experiments were conducted to analyze the effects of toolpath parameters on the engagement angle and the cutting force. The results show that the compression ratio has the most significant effects. A compression ratio of 50% is optimal, using which the total toolpath length is reduced by 34.0%, and the variance of the engagement angle is reduced by 31.2% compared with that of the true trochoidal toolpath. The profile of the total cutting force corresponds to that of the engagement angle.},

The tool duration data were collected and used to identify the parameters of the Taylor's model. Different end-of-life criteria for the tool inserts were even investigated. The achieved results are compared to those obtained using conventional cooling. It was observed that at low cutting velocity, conventional cooling still assures longer tool lives than in cryogenic condition. Since in cryogenic milling the increasing of the cutting velocity is not so detrimental as in conventional cutting, at high cutting speed (from 125 m/min) longer tool durations can be achieved. Statistical analyses on the model parameters were carried out to confirm the presented findings. The analysis of the effect of the cooling approach on the main wear mechanisms was also reported. At low cutting speed, adhesion and chipping phenomena affected the tool duration mainly in cryogenic milling.},

	abstract = {For high-speed machining, special tool paths are required wherewith the tool load is well-controlled, and the path is sufficiently smooth. One of the most effective solutions for controlling the tool load is to keep the cutter engagement constant. For this purpose, advanced tool path generating cycles are available in CAM systems. In case of slot machining, these cycles result in a trochoidal tool path. Since the CAM systems generate these tool paths regardless of the special geometric boundary conditions, each trochoidal period must be calculated separately. However, in our previous researches, it has been observed that the loops of the trochoidal tool path which provide a constant cutter engagement become uniform after a few periods. In this paper, a new method is presented, which can be used for generating this uniform trochoidal tool path shape. The developed method was compared to conventional trochoidal strategies, that were using circular or cycloid curves, and it proved to be significantly better than the traditional solutions. Considering its improved machining efficiency, simplifying the calculation process of this modern strategy can facilitate a wider use. In addition, the formal description of the path generation method provides further opportunities for optimisation.},

	abstract = {The digitization thrust on high-value manufacturing and services opens up new opportunities for ensuring total system uptime, reliability, and efficiency particularly for mission-critical high-value assets. The digitization process evolves intelligent manufacturing systems (IMS) which transforms maintenance into predictive reliability for achieving consistent quality throughout manufacturing process. This article unveils the intelligent grinding systems (IGS) for challenging grinding applications. In order to provide a better chance for value addition, previous work has been scrutinized extensively in the following aspects: grinding models, process design algorithms, and process monitoring. This then leads into an analysis of various previously designed IGS. The main focus, especially in the early 2000s, was mainly database development and parameter selection, which then shifted to process monitoring and control as particular technology advances were made. In the various goals that were investigated, it was evident that researchers were aiming for an online real-time system. This notion was driven by the advances in artificial intelligence and improved monitoring sensors, for example, acoustic emission sensors and even other unusual sensors like microphones for more economical and improved data collection and analysis. Although tremendous strides have been made, a substantial amount of work is still required in achieving a full-fledged real-time intelligent grinding system. The comprehensive findings on IGS system concludes that the real-time process update has been improved from few hours to milliseconds. © 2021, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.},

	abstract = {Hybrid manufacturing machine tools have great potential to revolutionize manufacturing by combining both additive manufacturing (AM) and subtractive manufacturing (SM) processes on the same machine tool. A prominent issue that can occur when going from AM to SM is that the SM process toolpath does not account for geometric discrepancies caused by the previous AM step, which leads to increased production times and tool wear, particularly when wire-based directed energy deposition (DED) is used as the AM process. This work discusses a methodology for approximating a part's surface topology using on-machine contact probing and formulating an optimized SM toolpath using the surface topology approximation. Three different geometric surface approximations were used: triangular, trapezoidal, and a hybrid of both. SM toolpaths were created using each geometric approximation and assessed according to three objectives: reducing total machining time, reducing surface roughness, and reducing cutting force. Different prioritization scenarios of the optimization goals were also investigated. The optimal surface approximation that yielded the most improvement in the optimization was determined to be the hybrid surface topology approximation. Furthermore, it was shown that when the machining time or cutting force optimization goals were prioritized, there was little improvement in the other optimization goals.},

	abstract = {In the case of 2.5D rough milling operations, machining efficiency can significantly be increased by providing a uniform tool load. This is underpinned by the fact that uniform load has a positive effect on both tool life and machining time. Unfortunately, conventional contour-parallel tool paths are unable to guarantee uniform tool loads. However, nowadays there are some advanced path generation methods which can offer a constant tool load by controlling the cutter engagement angle. Yet, the spread of these non-equidistant offsetting methods is hindered by their dependence on complex calculations. As a solution to this problem, the Fast Constant Engagement Offsetting Method (FACEOM), developed in the scope of our previous study, is seen to be taking a step towards reducing computational needs. In this paper, suggestions for further improvements of FACEOM are presented. Decreasing the number of path points to be calculated is made possible by implementing adaptive step size and spline interpolation. Through simulation tests, it was also analysed which of the numerical methods utilized for solving boundary value problems can be applied to obtain the shortest calculation time during tool path generation. The practical applicability of the algorithm has been proved by cutting experiments. With respect to research results, this paper also describes how a tool path created by the algorithm can be adapted to controllers of CNC machine tools. Solutions presented in this paper can promote a wider application of a modern path generation method that ensures constant tool loads.},
