Abstract:

The cutting force, cutting temperature and mechanisms are studied by Finite Element Method during the orthogonal metal cutting of Ti-6Al-4V with micro-textured cutting tools. The relation between the texture’s antifriction effect and the parameter of the textures is analyzed. The Derivative-Cutting phenomenon is found when cutting Ti-6Al-4V using textured tools. The mechanisms about how the micro-textured tools change the frictional behavior in the chip-tool interface are explained using Derivative-Cutting characteristic. The antifriction performance of micro-textured cutting tools in the metal cutting process is discussed. The cutting force and cutting temperature is decreased effectively in the cutting simulation with the micro-textured tools manufactured in reasonable parameters.

Abstract:

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.

Abstract:

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:

Metal-cutting tools during the machining of parts by cutting experience high strength and thermal loads, causing wear of the cutting edges. Increasing the wear resistance of the cutting edges of a metal-cutting tool is an urgent task. (Research purpose) The research purpose is analyzing the causes of wear of end mills and drills and proposing the most rational method of hardening metal-cutting tools. (Materials and methods) End mills and drills were chosen as the object of research. The BIG-5 installation with the use of electrodes made of hard alloys VK8 and T15K6 was used to harden metal-cutting tools. It was pointed out that relatively mild electrical modes with pulse energy from 0.05 to 0.2 joules are used to harden drills and end mills, the thickness of the applied coating layer in such modes is 10-30 micrometers. (Results and discussion) It was noted that the performed analysis of the applied hardening methods confirmed the feasibility of using electric spark processing for these purposes. The optimal modes of electric spark processing were selected on the basis of previous studies. Comparative tests for wear resistance of samples from materials of end mills (P18) and drills (P6M5) were performed. It was shown that when using electrodes made of T15K6, the wear resistance of the samples increases by 1.85 times for P18 and by 8 times for P6M5. Comparative tests of hardened end mills and drills for wear resistance were carried out. The indicator was the number of processed parts. (Conclusions) The result of using the electric spark processing method to harden the cutting tool was an increase in the life of end mills by 3.8 times, drills by 2.25 times. The productivity of manufacturing parts has increased.

Abstract:

Metal cutting processing is the most fundamental, most widely and the most important processing in industrial production. Because the development of mechanical manufacturing level plays a very important role in the coating technology material machining process. A coated carbide cutting tool with its high hardness and high wear resistance, good chemical stability and extensive compatibility characteristics, is widely applied in the metal cutting processing field. The author mainly studies the cutting force contrast between coated carbide cutting tools and not coated ones. Cutting tests have testified that if PVD technology applied on cutting, the cutting force of hard alloy cutter will alter with the change of feeds (f), depth of cutting (ap) and cutting velocity (v). The experiment suggests that the size of three-way cutting force of either the brand ZP25 hard alloy cutter or the carbide cutter by employing matrix ZP25 hard alloy cutter to respectively using PVD technology coat TiN or TiCN coating is successively FZP25>FTiCN>FTiN. The main reason for this is that the difference of frictional factor of the three kinds of cutter material and the workpiece material.

Abstract:

The formation of metal products in machining processes is carried out with the help of cutting tools. The principle of metal cutting is essentially rubbing and pressing, so in long-term use, the cutting tools will experience wear and require reconditioning. Tool reconditioning through sharpening is done by gently rubbing it against a grinding wheel, where the abrasive material on the wheel will cut or erode the tool. Sharpening can be done by machine or manually. The sharpness and geometry of cutting tools greatly determine the quality of metal manufacturing products. From the observations of partners, the skill of manually sharpening cutting tools is not yet possessed by the teachers or students of Muhammadiyah 1 Klaten Utara Vocational School. This community service activity is carried out by providing knowledge about cutting tools and manual sharpening skills. The target output is an improvement in the sharpening technique competency, especially for the teachers of Muhammadiyah 1 Klaten Utara Vocational School, and it is expected to be taught to their students.

Abstract:

Diamond film coated hard metal cutting tools are indispensible for high efficiency machining of materials which are difficult to cut by ordinary tools, and are successfully used in the dry cutting of high silicon content Al-Si cast alloys, graphite, carbon reinforced composite (CRFC) and metal matrix composite (MMC) , ceramics, and many other materials. In the present presentation, a novel process of High Current Extended DC Arc (HCEDCA) plasma CVD for mass production of diamond film coated hard metal cutting tools is presented. Besides, a novel process for the pretreatment of the hard metal cutting tool substrate, which involves the idea of “surface engineering” consisting of boronizing and alkaline and acidic etching is also discussed, by which the adhesion of the diamond film coating to the hard metal substrate can be greatly enhanced. Highly adherent and uniform diamond film coatings are successfully obtained. Diamond film coated WC-6wt%Co indexable tool bits, drills, endmill samples have been produced and been shown having excellent cutting performance by field cutting tests in dry cutting of Al-12%Si cast alloy and Al-15% SiC MMC materials.

Abstract:

Modern trends in metal cutting, high speed/feed machining, dry cutting and hard cutting set more demanding characteristics for cutting tool materials. The exposed parts of the cutting edges must be protected against the severe loading conditions and wear. The most significant coatings methods for cutting tools are PVD and CVD/MTCVD today. The choice of the right substrate or the right protective coating in the specific machining operation can have serious impact on machining productivity and economy. In many cases the deposition of the cutting tool with a hard coating increases considerably its cutting performance and tool life. The coating protects the tool against abrasion, adhesion, diffusion, formation of comb cracks and other wear phenomena.

Abstract Machining metal alloys such as AZ31 magnesium alloy involve thermomechanical behavior between workmaterial and cutting tools. The interaction between workmaterial and cutting tools has affected the chip formation in metal cutting and cutting performance. This paper developed a finite element model (FEM) by using Abaqus software to simulate the chip formation in cutting AZ31 magnesium alloy under dry condition. The study revealed that serrated chips were formed in dry condition. Chip segmentation increased proportionally with cutting speed as generated heat concentrated in a narrow zone, promoting the formation of an adiabatic shear band.

A coated carbide cutting tool with its high hardness and high wear resistance, good chemical stability and extensive compatibility characteristics, is widely applied in the metal cutting processing field. It is one of the cutting tools, belonging to the current focus research and development project of all countries in the world. The author mainly studies the cutting force contrast between coated carbide cutting tools and not coated ones. At the same time study them on the rake face friction coefficient contrast and the chip deformation coefficient contrast so as to explain the reasons for coated cutting tool cutting force decrease. The research indicates that, in machining course, applying physical vapor deposition coated technology (PVD) of carbide cutting tools cutting force change with feeds, cutting depth and speed is the same as not coated carbide cutting tools. But coated carbide cutting tools cutting force is obviously less than that of not coated carbide cutting tools. The main reason is that the friction coefficient between the two kinds of cutting tool materials and the workpiece is different. The result of study will help popularization and application of coated carbide cutting tools.

Abstract:

Purpose This study aimed to clarify the influence mechanism of conical micro-grooved texture on the tool–chip friction property and cutting performance of WC-TiC/Co cemented carbide tools under flood lubrication conditions. Design/methodology/approach Conical micro-grooved texture was fabricated on the tool rake face using laser texture technology. Metal cutting tests were conducted on AISI 1045 steel with conventional and developed tools for various cutting speeds (80 m/min to 160 m/min) and conical angles of micro-grooved texture (2 ° to 5 °) under flood lubrication condition. The effect of conical micro-grooved texture on the tool cutting force, tool–chip friction coefficient, surface roughness of the machined workpiece, and wear of the tool rake face was determined. Findings Unlike the conventional tools, the conical micro-grooved tools successfully resulted in reductions in metal cutting force, tool–chip frictional coefficient, surface roughness of the machined workpiece, and wear of the tool rake face. These reductions were more noticeable than those of conventional tools with increases in the cutting speed and conical angle of the micro-grooved texture. Detailed research indicated that conical micro-grooved channel exhibits a directional motion characteristic of liquid, which accelerated the infiltration of cutting fluid at the tool–chip interface. Substantial cutting fluid was supplied and stored at the tool–chip interface for the conical micro-grooved tools. Therefore, the conical micro-grooved texture on the tool rake face showed evident advantages in improving tool–chip friction and tool cutting performance. Originality/value The main contribution of this study is proposing a new conical micro-grooved texture on the tool rake face, which improved tool–chip friction and tool cutting performance.

Abstract:

In machining processes, cutting tools play a dominant role in producing quality products. The quality of finished goods is directly related to the cutting tool condition. Several types of research have been carried out in cutting tool condition monitoring. On the other hand, the manufacturing industries should be aware of the cutting tool selection, operating conditions, and performance of cutting tools. This article emphasizes the performance of coated cutting tools and tool materials for various machining operations. Nowadays, the nanocoating of CNC tool inserts increases the wear resistance, vibration emissions, metal removal rate, etc. These coating techniques influence the manufacturing industry to increase the productivity and quality of the finished goods and reduce the machining cost. The performance of thin film multilayered coatings such as TiN, TiAlN, AlTiN, Ti, and TiCN on plain silicon carbide tool inserts is revealed by the researchers to guide the manufacturing industry for proper tool selection and standard machining inputs for metal removal operation. The influence of coating material such as TiBN, TiN, TiAlN, and CrAlSiN in cutting tools leads to increase the life time of the cutting tools, which decreases the material sticking and cutting forces. Titanium carbo nitride is wear-resistant and corrosion-resistant. Compared to TiCN, TiAlN is harder due to the higher hardness of 32 GPa. This article concludes the material selection based on the work piece material which yields good metal removal with less cutting forces. The article concludes the cutting material selection based on the work piece for machining operations.

The general mathematical model of metal-cutting systems accuracy is presented in this work. The general model is the basis to develop the full mathematical model of turning metal-cutting system accuracy. The results of accuracy modeling at turning with a wide cutter are received when studying nature of influence of the lathe and the cutting tool geometrical errors on processing accuracy of cylindrical and face surfaces.

Diamond film made by adopting the Chemical Vapor Deposition (CVD) technology is a promising superhard material. The mechanical and physical properties of CVD diamond is between natural diamond and hot press polycrystalline diamond. The cutting tools made by CVD diamond can machine many kinds of material, such as nonferrous metals, non metallic materials and composites. CVD diamond is classified as thin and thick films, and the thick film cutting tools are widely used. However, the superhard cutting tools cannot be applied to the cutting of iron family metal and molybdenum (Mo). In this paper, data and curves on machining test of CVD diamond cutting tools are listed and then analyzed.

Abstract:

Taking into account the growing demand for sophisticated cutting tools in terms of their performance, new approaches, besides the development of the tool’s cutting edge, have to be investigated and validated by physical tests. In this study, methods of topology optimization and hybrid design are adopted for cutting tools. After a quick overview of its motivations, reduction of mass, the design of load paths, and beneficial functions within tool bodies, a structured method and its application on a long shell end mill for metal cutting is described as part of a holistic approach at the system and component levels. The manufacturing of the resulting geometry is examined for additive manufacturing. The optimized structures reduce the spindle power required, especially for acceleration to the desired speed; this, in turn, decreases the energy consumption of the process. Besides bearing static and dynamic loads, composites provide the adjustable option in process-stabilizing damping. In the field of wood cutting, the cutting forces are lower than those in the machining of metals. Here, we describe a planing tool with a large overhang and the first step in its development. The finite element analysis within the software Ansys Workbench and CompositePrep/Post (ACP), the special tool for modeling reinforced structures, are utilized for preparing the layout of the tool. To ensure the structural integrity of fiber reinforced plastic (FRP), the failure criteria proposed by Puck are applied. The overhanging planing tool is clamped on one side. It shows the principles for the development of a prototype and forms the basis for tools with even larger diameters and benefits. The underlying concept of the planing tool prototype is an innovative sandwich concept, wherein sleeves are used to join metal with carbon fiber reinforced plastic (CFRP) in a micro-forming process. Besides the abovementioned advantages, the reduction of acoustic emissions in the very noisy field of wood machining is a promising application.

In high speed machining of hard materials, tools with chamfered edge and materials resistant to diffusion wear are commonly used. In this paper, the influence of cutting edge geometry on the chip removal process is studied through numerical simulation of cutting with sharp, chamfered or blunt edges and with carbide and CBN tools. The analysis is based on the use of ALE finite element method for continuous chip formation process. Simulations include cutting with tools of different chamfer angles and cutting speeds. The study shows that a region of trapped material zone is formed under the chamfer and acts as the effective cutting edge of the tool, in accordance with experimental observations. While the chip formation process is not significantly affected by the presence of the chamfer, the cutting forces are increased. The effect of cutting speed on the process is also studied.

Abstract:

By 3D finite element simulation for temperature field and tool wear of SiCp/Al metal matrix composites under the condition of high speed milling, we draw a conclusion that the most significant influence on cutting temperature is cutting speed, less is feed rates, the minimum is cutting depth, which is exactly the same as the influence law of ordinary metal cutting. In the course of high-speed milling SiCp/Al by PCD tools, the higher the cutting speed is, the bigger wearing depth of tools is. When v=300m/min, ap=0.5 mm, f=0.3 mm/r, the transient temperature in the milling would reach to 619°C. Such a high temperature can cause graphitizing wear of the PCD tools. Because of the effectiveness of the simulation’s conclusion, it is vital significance to the reasonable options of cutting parameters and the prolongation of tool life.

Abstract:

Purpose: To present a technology for hardfacing of metal-cutting tools by arc welding in vacuum. Design/methodology/approach: The experiments were carried out using an installation for arc welding in vacuum. Objects of research were metal cutting tools (lathe knives), made of high-speed steel HS6-5-2 on a base metal of structural steel C45. The structure, hardness and wear resistance after hardfacing and after a triple tempering at 560°C have been determined. The heat resistance of the obtained instruments has been examined. Findings: The microstructural analysis showed that the structure of the built-up layer consisted of martensite, retained austenite and carbides. This was confirmed by the values of measured hardness after welding which were about 63-64 HRC. The triple tempering led to an increase in hardness by 3-4 HRC. It was found that the built-up layers (cutting edges of tools) retain their hardness (HRC=63-65) up to a temperature of 615-620°C, which shows that the heat resistance of the build-up layers was similar to that of the hardened and tempered tools of the same steel. The built-up work-pieces (excluding heat treated) and the reference knife showed the same cutting qualities at cutting speeds in the range of 55 to 120 m/min. It has been found that triple tempering after hardfacing led to increased wear resistance and consequently the durability of the tool also increased due to the higher hardness. Practical implications: The practical application is related to the production of metalcutting tools. Originality/value: The proposed technological method allows to produce defects free built-up layers. The cutting properties of the built-up in vacuum layers are comparable to or better than those of new tools made of steel HS 6-5-2.

Abstract:

The heat generation during metal cutting processes affects accuracy of the machined surface and strongly influences cutting forces and tool wear. Material property of coated tools is one of the most important factors effecting heat conduction and temperature on the rake face of coated tools. To find the action of thermal properties of coated cutting tools on cutting temperature, the temperature distributions were obtained with temperature-dependent properties and temperature-independent properties of coated tools using numerical method. The results indicated that temperature-dependent properties should be considered when calculating cutting temperature. To simplify calculation, selecting the thermal conductivities at average temperature to substitute for temperature-dependent properties can reduce calculating error. The conclusion provides a methodology for analysis of cutting temperature of coated tools, design of cutting tools and analysis of thermal stress within coated tools in manufacturing industries.

Abstract:

There are many factors having effects on the cutting performance and useful time of cutting-tools, such as cutting-tools material, geometry parameters, structure and the optimization of cutting parameter, etc. But the condition of cutting-tools edge shouldnt be ignored. As is known to all, the micro gaps of cutting edge extend easily in the process of cutting, and accelerates the wear and damage of tools. As for the current situation of low passivation efficiency in edge, high loss of passivation and uncontrollability in blade shape, some improvements and new technology for applying to tools passivation are proposed based on the analysis and research about carbide tool passivation. Whats more, some exploration experiment will be done. The results show that those passivation technology can improve the processing efficiency of metal-cutting, cutting tool expectancy and reduce manufacturing cost.

Abstract:

When machining difficult-to-cut metal materials often used to make sheet metal forming tools, excessive cutting force jumps often break the cutting edge. Therefore, this research developed a system of three neural network models to accurately predict the maximal cutting forces on the cutting edge in helical end milling of layered metal material. The model considers the different machinability of individual layers of a multilayer metal material. Comparing the neural force system with a linear regression model and experimental data shows that the system accurately predicts the cutting force when milling layered metal materials for a combination of specific cutting parameters. The predicted values of the cutting forces agree well with the measured values. The maximum error of the predicted cutting forces is 5.85% for all performed comparative tests. The obtained model accuracy is 98.65%.
