This article presents the results of research funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (grant № AP14972884 "Increasing wear resistance of metal-cutting tools by the method of lapping"). There was investigated the state of the metal-cutting tools' wear problem in the conditions of machine-building enterprises of the Republic of Kazakhstan (RK). It is revealed that metal-cutting tools do not always endure the durability period according to the standards and are exposed to premature wear of cutting edges, breakage, and chipping. The factors affecting the wear resistance of metal-cutting tools and the existing possibilities for their improvement are also studied. The article proposes the method of pretreating cutting tools in order to improve the wear resistance and durability of metal-cutting tools under the conditions of domestic machine-building industries. The formation of secondary structures on the working surfaces of the tools, which is one of the manifestations of the fundamental law - structural adaptability was studied on the basis of the results of the analysis of previously conducted works.

As the North American nonwovens market has matured over the last ten years, computer-aided design, engineering and flow analysis have established themselves as effective engineering tools to complement and optimize traditional design, analysis and testing. This has lead to significant cost and time savings in the product life cycle. More specifically, these tools mainly impact pre-market activities, thus they reduce time-to-market and overall development expense. This paper demonstrates the successful use of computational fluid dynamics (CFD) tools to achieve cost-effective design analysis and optimization. Examples of airflow delivery systems (fan/blower design and jets/diffusers in spun bond process) and analysis of filter performance are shown

Abstract:
The aim of this work is to develop techniques and to optimize the process of bonding of cemented carbide metal cutting inserts. This replaces the common methods of clamping or brazing. The first stage was to-survey and test structural adhesives to select the most promising adhesive for metal cutting applications. This resulted in a choice of toughened epoxy heat cured adhesive. A comparison between bonded and brazed joints, from the damping capacity point of view was made. In this comparison adhesive bonding resulted in, a higher damping capacity when compared with brazing. The bond line thickness proved to be significant in increasing the damping capacity of the bonded joints. A comparison was carried out between the heat flow through bonded and brazed tools, and demonstrated pronounced heat insulation in the bonded tool, which depended mainly both on the thermal conductivity of the adhesive material and the thickness of the bonded layer. The effectiveness of the bond line thickness, from the points of view of thermal conductivity and developed thermal stresses was investigated. This showed that the thinner the bond line the better is the performance of the bonded joint. The effect of coolant on the temperature of the bond line as well as the tool tip was also investigated. Mixing metallic powder with the adhesive material in order to increase the thermal conductivity of bonded tools was investigated. A new apparatus for measuring low thermal conductivity is proposed. Extensive cutting tests were carried out in order to assess the performance of bonded tools with and without coolant, reground tools and bonded tools having copper powder mixed with the adhesive. The assessment of cutting performance when using bonded tools compared with brazed tools showed that not only a better surface finish could be obtained with bonded tools but also far less tool flank wear

Abstract:
This PhD thesis is based on six articles and proposes new approaches for modelling of the life of cutting tools and for determining the optimal tool replacement time. These issues are very closely related and play a critical role in machining economics. Replacing a tool too early means wasting of its potential and leads to high costs and reduced productivity. Late replacement poses a risk of wear-out and other types of tool failures, which can damage the component being produced and can cause expensive equipment downtimes. Therefore a lot of work has been done to develop models for predicting the life of a tool and to optimize its replacement time. Probably the best known of them is the Taylor’s tool life equation. Developed in 1906 Taylor’s equation expresses the tool life in terms of the cutting speed. Despite being over a century old, this model is still widely used in practice. However, Taylor’s equation has a few drawbacks. For example, it ignores the effect of other, though less important, process parameters such as the depth of cut and the feed. To walk around this issue several extensions of Taylor’s equation have been proposed and are discussed in this thesis. Nevertheless all these models share another common flaw. They assume that tool life is deterministic, i.e., that given the process parameters the exact time to wear-out can be calculated. Unfortunately, in real machining processes there are a lot of sources of variation that affect the rate of tool wear and influence its life. As a result, deterministic models rarely give accurate estimates and are only valid as approximations. To improve tool life predictions and assist process planners in choosing the optimal replacement time this PhD thesis proposes new methods. The underlying assumption is that tool life is a stochastic quantity and follows a certain probability distribution. With this in mind the reliability function is derived. Based on the physical analysis of machining processes it is assumed that a tool can fail due to the three main causes: (i) wear, (ii) internal defects and (iii) external stresses. Tool wear depends on a number of factors, including the characteristics of the tool itself, such as its material, geometry and coating, properties of the workpiece material, cutting parameters, rigidity of the machine tool and the efficiency of the cooling process. This last factor is particularly important as most of the tool wear mechanisms depend on temperature. Therefore in this PhD thesis a lot of attention is given to high pressure cooling, which is an effective way to reduce the temperature in the cutting zone. Internal defects are micro voids and cracks that develop inside the tool material during its manufacturing process or as a result of inappropriate handling. They act as stress concentrators and lead to shorter than normal tool life. External stresses are severe overloads that cause immediate tool failure regardless of its quality. They are random in nature and may originate from machine operator errors, failure of supporting equipment or some other external sources. Considering all three failure modes total tool reliability function is found. It is assumed that in a given batch a certain percentage of tools are “bad”, i.e., they contain internal defects, while the rest are “good”. The life of the normal tools is modelled by a two-parameter Weibull distribution. Failures due to internal defects are also accounted for by the Weibull distribution, but with different parameters. Then the life of a tool chosen at random is predicted by the mixture model. In addition, tools of both types can fail due to external stresses, the occurrence of which is model by a homogeneous Poisson process. The derived tool reliability function is used to determine the replacement time. Two models are proposed for this purpose. The first one is called the minimum acceptable reliability approach. The idea is to select such a replacement period that the reliability of the tool during it would not fall below a certain minimum level. We show that, when the reliability function is known, this can be done by using a simple graphical procedure. The second model is based on the age replacement policy, which attempts to balance the costs of preventive and failure provoked tool changes. To solve this optimization problem the total time on test (TTT) transform of the reliability function is introduced, and a method for estimating it form the experimental data is proposed. Then, as in case of the first model, the replacement time is found by employing a simple graphical procedure. For the above approach to be used in practice the expected costs of preventive and failure provoked replacements need to be known. It is shown that the former one can be determined by applying traditional formulas found in machining economics handbooks. The penalty cost, on the other hand, is not so well defined, and no good estimation models are available. Therefore, a new, probability tree-based approach is developed in this thesis. The relevance and the applicability of the proposed models is tested in a few experimental and case studies described in the appended articles. In Article 1 reliability of machining systems as a whole is investigated, and the stochastic nature of the processes involved is clearly shown. In Article 2 it is demonstrated that a two-parameter Weibull distribution can be used to model the tool life, and a simple replacement model based on the reliability function is proposed. In Article 3 a more generic tool life model is developed, but a two-parameter Weibull distribution is still found to be a good approximation. The replacement time is than found by employing an optimization procedure based on the age replacement policy. In Article 4 an approach for estimating the penalty cost, which is a key input to the age replacement model, is developed. Finally in Articles 5 and 6 it is shown that high pressure cooling can help to extend the tool life and possibly to reduce its variation, which is the main reason why probabilistic models are needed. Based on this experimental work and case studies the thesis concludes that stochastic approaches for tool life modelling and for determination of replacement time are relevant and applicable in practice. Therefore further work needs to be done to extend the use of these methods beyond the set-ups and conditions tested throughout the research described in this PhD thesis.

Abstract:
The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life. The objective of this work is to understand the effects of alloying element additions to workpiece steels on material transfer and the roles of the formed transfer layers on friction characteristics and wear of tools. To isolate and study the influence of the individual alloying elements, model steels are specifically designed. These steels include one reference with C as the only alloying element and others alloyed also with single additions or combined additions of 1 mass% Si, Mn, Cr and Al. The experiments are performed using both a sliding test, simulating the material transfer in milling, and a turning test. In a sliding contact, the mode of transfer is strongly dependent on the normal load and sliding speed. Material transfer initiates extremely fast, in less than 0.025 s, and characteristic transfer layers develop during the first few seconds. The different steel compositions result in the formation of different types of oxides in the transfer layers. At the workpiece/tool interface where the conditions involve high temperature, high pressure and low oxygen supply, easily oxidized alloying elements in the steel are preferentially transferred, enriched and form a stable oxide on the tool surface. The degree of enrichment of the alloying elements in the oxides is strongly related to their tendencies to become oxidized. The difference in melting temperature of the oxides, and thus the tendency to soften during sliding, explains the difference in the resulting friction coefficient. The widest differences in friction coefficients are found between the Si and Al additions. A Si containing oxide shows the lowest friction and an Al containing oxide the highest. The damage mechanism of coated tools is chiefly influenced by the form and shear strength of the transferred material. Absence of transfer layer or non-continuous transferred material leads to continuous wear of the coating. Contrastingly, continuous transfer layers protect it from wear. However, transfer layers with very high shear strength result in high friction heat and a large amount of steel transfer. This leads to rapid coating cracking or adhesive wear.

Abstract:
Despite criticisms of its methodology, the Taguchi philosophy for quality improvement is generally applauded. Though originally intended to primarily achieve its results "off line", during the product design phase and before manufacturing, it has frequently also been deployed to solve problems "on line". Taguchi identifies the crucial design phases as "system design" and "parameter design", and his statistically-based tools are directed at the latter. The general objective of this investigation is to study two contrasting approaches to product and process optimisation, ie Genetic Algorithms, which may be appropriate to both "system design" and "parameter design" phases, with Taguchi and related statistical tools which may be appropriate to the "parameter design" phase. The literature review concentrates on the up and downsides of Taguchi Methods, focusing on the philosophy and methodologies. Its statistical content, particularly related to the use of Signal-To-Noise ratios and saturated fractional factorial designs, have widely reported deficiencies. In order to evaluate and, if necessary, overcome these deficiencies, a combination of Taguchi and non- Taguchi tools are brought into an experimentation strategy to determine robust methodologies that contribute to enhanced product performance. The approach is motivated from a design for quality standpoint and is directed principally at improving performance. The approach is illustrated using three case studies in surface finish from metal cutting and simulation systems optimisation. These case studies involve a variety of experiments different in nature, from real physical experiments to computer-based ones, and tackling a wide range of different problems such as: surface finish in milling and turning machining (metal cutting), optimum travel time and traffic junction control (transport traffic simulator) and out-of-balanceforce problem (optimisation of simple Genetic Algorithms). The study of Taguchi tools is an extension of previous work by Taher (1995). Some of his investigations are extended, principally the reliability of Taguchi saturated fractional factorial arrays, the need for factor/level analysis, criticisms of the Taguchi Signal-to-Noise ratios and the use of sequential experimentation. In addition to these, attention is focussed on the use of repetitions within the Taguchi methodology, the use of transformations or Generalised linear Models and the possibility of using robust statistics. The adoption of a sequential experimentation approach leads to a successful use of predefined Taguchi arrays influenced by user knowledge of confounding and interaction effects on main factors. From a global viewpoint, Factor/Level analysis is highly recommended. It is also determined that the reliability of results is highly affected by the use of Signal-to-Noise ratios, and alternative dispersion control tools are strongly advised. Taguchi's robust design methodologies are of value but require integration with other design and quality assurance methodologies, such as Concurrent Engineering and Quality Function Deployment. The optimisation of a simple Genetic Algorithm (for the out-of-balanceforce problem) is used as one test case for the investigation of Taguchi tools. However, this investigation is itself of interest for the general use of genetic algorithms as it addresses issues such as appropriate population size and choices for crossover and mutation modes and probabilities. Many previous investigations of these have only been of the "one factor at a time" type.

Abstract:
AbstractThe dry machining strategy has recently received high attention in the field of metal cutting as it can eliminate the environmental impacts associated with the usage of cutting fluids. However, high-generated heat and severe tool wear are usually observed for the dry machining operations. One of the suggested techniques to improve the dry machining performance is to utilize the textured cutting tools, reducing the friction at the chip-tool interface. In this study, three different micro-textured tool designs were used during the machining AISI 1045 at different cutting conditions. A life cycle assessment was performed including the power consumption for preparing the textured tool designs and the measured power during the machining experiments. Furthermore, some measured machining outputs (flank wear, surface roughness, and the unit volume machining time) were further included to offer a comprehensive and effective sustainability assessment for the performance of the utilized textured tools. The performance of these textured tools was also compared with the non-textured tool under the same cutting conditions. The textured tool design with narrow micro-groove width showed better sustainable performance compared to the non-textured tool and other textured tool designs.

Abstract:
AbstractTool wear and the decision when to replace tools is a universal challenge in the metal cutting industry. While the tool wear state can be accurately determined using optical measuring methods, the tool wear of milling tools is often examined by the CNC-machine operators, especially in small and medium enterprises. In order to increase the accuracy with which tool wear can be correctly classified, it is advisable to use an assistance system that automatically removes the tools from a buffer, examines the tool wear state based on visual sensor data and sorts them into separate boxes according to the classification result. In this context, the accurate classification of tool wear is a key capability that can be enabled using methods of machine learning, based on image data that was labeled by human experts. In this paper different machine learning models are examined based on their ability to classify images of milling tools into the categories worn and not worn. The EfficientNet_b0 model achieves an accuracy of 91.47% and outperforms human experts that classified similar images by 22.87%.

AbstractThe efficiency and service life of products made from metal-ceramic tool alloys and used as cutting tools and friction units are determined by a combination of physical and strength properties of their surface layers with a thickness of up to 200 μm. Therefore, much attention is paid to their improvement at the present time. An effective way to increase the operational properties of the metal-ceramic alloy products is to modify the structure and the phase composition of the surface layers by forming multi-scale internal structures with a high proportion of low-dimensional (submicro and nano) components. For this purpose, surfaces are treated with concentrated energy fluxes. Pulse electron-beam irradiation (PEBI) in an inert gas plasma is one of the most effective methods. This chapter presents results of theoretical and experimental studies of this process. An example is the nanostructured hardened surface layer on the TiC-(Ni-Cr) metal-ceramic alloy (ratio of components 50:50) formed by PEBI in the plasma of argon, krypton, and xenon. Its multi-level structure, phase composition, as well as tribological and strength properties are shown.

Abstract:
Additive manufacturing provides new opportunities for cutting tools, enabling geometric freedom to enhance functionality and performance. The challenge in realizing the full potential is multifarious: additive manufacturing needs to match the material quality of existing processes while creating these complex geometries. At the same time the engineered tool designs have to make use of the geometric freedom to exceed the capabilities of conventional tools. This work will highlight some challenges and solutions in processing cemented tungsten carbide as well as hot work tool steel. The presentation will also discuss opportunities with respect to tool design and show examples of innovative structures.

Abstract:
In machining operation, cutting tool performs a central role towards the overall machining performance. A user from metal cutting community always look for better cutting tools that can enhance productivity by reducing tool wear and cost. Modification in the micro-geometry of cutting edge is termed as edge preparation, and it is performed to improve the machining performance by strengthening the cutting edge, reducing internal stresses of coating and lowering the edge chipping etc. Edge preparation has a controlling influence on the formation of deformation zones, cutting temperature, cutting forces and stresses at the cutting interface. Vibration assisted machining (VAM) concept is gaining fame in the metal cutting sector community for machining difficult-to-machine materials. In VAM, cutting tool moves with a small amplitude vibration instead of moving with a constant cutting velocity. This small amplitude vibrational movement provides better machining performance for difficult-to-cut brittle materials. The current numerical study utilized different edge prepared micro-geometries such as sharp edge, round edge and chamfer edge etc. cutting tools, and then these cutting tools were used in the numerical simulations of VAM. The study shows higher magnitude of cutting forces under VAM with tools with modified geometry. The study is beneficial for the metal cutting community and opens new areas of industrial applications.

Abstract:
Analysis of tool-chip friction for tools with edge design in metal cutting helps to understand the complex material behavior around the cutting edge of the tool. The results of this analysis can be used to identify optimum tool edge design to achieve the most desirable machining performance. In this study, slip-line field analysis approach is used to investigate the average friction factor at the tool-chip interface and the dead metal zone phenomenon in orthogonal cutting for chamfered and honed tools. In an experimental set-up, an orthogonal cutting test of AISI 4340 steel is performed. Measured forces are utilized in identifying the friction factors at the tool-interface for both chamfered and honed tools for varying feed rates. Comparison of predicted and measured forces indicates good agreements. The results of this study can be utilized in designing friction at tool-chip interface for Finite Element simulations of machining with edge design tools. This study can also be extended to waterfall hone tools to identify the most optimum cutting edge geometry.

Abstract:
Abstract An assessment was performed of Russian needs and capabilities related to decommissioning wastes from nuclear submarines. Hydraulically operated hand-held metal cutting tools can provide improved productivity and safety during the size and volume reduction of bulky metal scrap. Such tools are commercially available in the US, but not in Russia. Also, they have not been previously deployed in Arctic conditions. A system of metal cutting and spreading tools has been procured, modified and successfully tested at the Cold Regions Research and Engineering Laboratory (CRREL), and are now being deployed to Russia’s Northern Fleet.
