Modeling of the shaping by a milling cutter is made while forming the internal gear teeth of the driven gear wheel. The estimate of the cutting edge rounding influence on the tool life taking into account the wear-resistant coating. The effects of radii of 10 μm, 15 μm, 20 μm, 25 μm are simulated. At the edge radius of 10 μm, the coating layer is rapidly collapses. At a radius of 15 μm, the highest tool life is obtained. At the more high radii, the tools durability is decreases. A practical experiment was carried out on a cupped skiving cutter with AlTiCN-coating (PVD). Processed steel 41CrAlMo7 with hardness 241-287НВ. The simulation results were confirmed, the highest tools lifetime at a radius of 16.13 microns for 60 parts. As a result, for this type of processing and for this coating type of the cutting tool, the most optimal cutting edge rounding can be considered as the value of 15-18 μm. It can be concluded that, perhaps, a more sharp edge from 10 to 15 μm can be a positive effect on tools lifetime, in the case of uniform rounding over the entire cutter edge of the tools tooth (on the top and side tooth profile).

Formation of roughness during treatment by polymer-abrasive brushes occurred as a result of interaction of cutting micro-relief with processed surface. The cutting micro-relief of abrasive instrument is described in the form of random process with normal distributional law. When calculation of roughness, the depths of penetration of cutting lugs in processed material as well as regularity of changing of radial radius of rounding of peaks of cutting lugs from modes of treatment are taken into consideration. Set are relations of roughness of processed edge from modes of treatment (deformations of instrument, cutting velocities, feeding) as well as from constituent cutting force. It is proved that usage of polymer-abrasive brushes for rounding of edges faces all requirements of aviation industry on roughness of processed edges.

The paper is devoted to a physical modeling of the process pertaining to interaction of the machined material with metal deposits along a hole edge which are obtained on a smooth tool surface due to its electro-erosion modification. A technique for obtaining single holes on a cutting tool (strip) is given in the paper. The paper describes main geometric elements which have obtained due to the action of a single electric discharge. Geometric parameters of a single hole initiated on a working strip surface in the course of this effect have been given in the paper. The paper provides a justification and description of a tape tool prototype used in the investigations brass band strips, on which a washer with different rounding radius of an outer edge is fixed. The prototype makes it possible to simulate metal deposits on the modified working surface of the strips. The paper presents methodology for carrying out experiments on investigations for interaction of the created strip prototype with a processed material, including a description of a device for studying the process of washer interaction with the samples from paraffin and gypsum. Photographs are given that allow to visualize a destruction process of samples which is caused by a washer (model of metal deposits). The paper shows stages of sample fracture when using washers with different rounding radius and describes nature of the destruction for various sample materials. The results of the conducted studies reflecting an influence of the shape of an outer washer edge, in particular a radius of its rounding, on the course of characteristic stages in the process of destruction of samples from paraffin and gypsum are presented and discussed in the paper. It has been experimentally confirmed that metal deposits which are formed at the hole edge and extend beyond an initial surface contour, represent cutting-deforming elements with a capability to destroy material which ranks below in hardness to metal of the deposits.

In modern multiuse cutting tools with exchange plate (e.g. with superfinishing edge or Wiper), the cutting edge is made without documenting the basis for optimizing its dimensions. The article presents a generalized edge wear model surrounded by a rounded tip. The proposed solution allows such a modification of edge corner – by determining the conditions of its work – to adapt the tool to stabilize the process of shaping the machined surface.

The work concerns an analysis of the wear mechanisms of punches in the nibbling process. The nibbling process is the multiple punching of holes or external contours using circular punches, the diameter of which is much smaller than the size of the punched shapes. Analytical, numerical and experimental studies were carried out. In the analytical solution, formulas for determining the pressures in the contact zone were developed, thus enabling a simple estimation of the designed nibbling tools. In numerical studies, the influence of the punch rounding radius on the fatigue wear was investigated. It has been shown that the change in the punch cutting edge radius from r = 0 mm to r = 0.5 mm enables a seven-fold increase in the fatigue wear resistance. It was found that the change in the punch cutting edge rounding radius has an impact on the quality of the product (the greater the radius r, the worse the technological quality of the product). In experimental studies, the abrasive wear process was primarily investigated. For this purpose, the nibbling process was tested on S235JR + AR steel sheets with tools made of NC11LV/1.2379 steel without any coating and with an AlCrTiN layer. It was found that the special AlCrTiN layer used allowed for an increase in the resistance to abrasive wear, and thus increased the service life by approx. three times. The last element of the work is an assessment of the technological quality of the product after nibbling depending on the degree and type of stamp wear (quantitative and qualitative assessment).

Modifying the piercing punch profile may have a positive effect on the belt perforation process. Using the proper shape of the tool may reduce the perforation force and improve the quality of the holes. However, complex geometry of the punch can also cause an adverse stress distribution, which leads to a faster tool wear. In the presented paper, several different piercing punch profiles were tested using FEM analyses in ABAQUS and the obtained stress distributions along its cutting edges were analyzed. For the selected group of the piercing punches, the influence of variable geometrical features (a radius of rounding, an angle of chamfering or a depth of the bowl) on the stress distribution were also shown. Based on the results, it is possible to predict how modifying the punch profile will affect the shortening of the tool life, compared to the basic flat-end cylindrical piercing punch. The following research can be useful in the design process of the punching tools used for vacuum conveyor belts perforation.

One of the main factors that determine the resistance of blade working bodies against damage under dynamic loads is their resistance to plastic crumpling, brittle or fatigue failure. Hard alloys that strengthen the blades of tillage parts are more brittle materials than steel, so the blunting of their edges is caused by the formation of cracks, their gradual growth or microchipping, even from a possible single impact of a solid inclusion in the soil. In addition to the usual brittle fracture of hard alloys, fatigue failure occurs under cyclic impact conditions. (Research purpose) The research purpose is in identifying the pattern of destruction of the blade edge of soil-cutting parts of forestry machines and theoretically justifying the algorithm for assessing the strength to determine the rational thickness of the wear-resistant coating during hardening. (Materials and methods) The article presents the main regularities of the influence of material properties and geometric parameters of the blade on the radius of rounding. (Results and discussion) The process of breaking the edge of the blade of hardened working bodies of forestry machines has been studied. The claim that the blunting of the blades is mainly due to its destruction and not to wear has been proved. The article presents a method for evaluating the strength of bimetallic blades of soil-cutting parts of forestry machines. It was found that the blunting of the blade occurs as a result of edge destruction in the process of multiple impacts of solid soil inclusions along the edge of the blade. (Conclusions) The article shows that the destruction of the edge of the blade leads to blunting of soil-cutting parts, which affects their performance. It was found that the sharpness of a self-sharpening hardened blade is determined by the thickness of the reinforcing layer and its ability to resist destruction under impact.

This paper presents a computational sequence for calculating the components of the cutting force and torque when milling with carbide end mills. The calculation algorithm includes the transition from the tangential and radial components of the force to the force components in the machine coordinate system. On the helical cutting edge, two parts are highlighted: one on the cylindrical (peripheral) surface and the other one on the arc of the rounded tip of the tooth. These parts of the cutting edge are divided into sections where the calculation is performed, followed by summation of the force components along the axes of the machine co-ordinate system and the moment relative to the axis of the cutter. An analysis of the components of the force and torque depending on the depth of cutting, feed, number of teeth of the cutter, blade wear and radius of the tip rounding is performed. The ratio of forces and moments for various milling conditions of structural carbon steel and aluminum alloys is shown. The developed algorithm is applied in a computational program that can be used to perform operational calculations of forces and torque for various milling conditions. The calculated parameters can be used as technological limiters in optimization problems, as well as for strength calculations of tools, milling equipment, and the selection of components of milling machine drives.

AbstractRaw pine wood processing and especially its mechanical processing constitute a significant share among technological operations leading to obtaining a finished product. Stable implementation of machining operations, ensuring long-term repeatable processing results depends on many factors, such as quality and invariability of raw material, technical condition of technological equipment, adopted parameters of work, qualifications and experience of operators, as well as preparation and properties of the machining tools used. It seems that the greatest potential in the search for opportunities to increase the efficiency of machining operations has the modification of machining tools used in it. This paper presents the results of research work aimed at determining how the life of cutting tools used in planing operations of wet pine wood is affected by the application of chromium aluminum nitride (AlCrN) coating to planar industrial planing knives in the process of physical vapour deposition. For this purpose operational tests were carried out under production conditions in a medium-sized wood processing company. The study compares the effective working time, rounding radius, the profile along the knife (size of worn edge displacement, wear area of the cutting edge), selected texture parameters of the planar industrial planing knife rake face and visual analyses of cutting edge condition of AlCrN-coated planar knives and unmodified ones. The obtained experimental results showed the possibility of increasing the life of AlCrN-coated knives up to 154% compared to the results obtained with uncoated ones. The proposed modification of the operational features of the knives does not involve any changes in the technological process of planing, does not require any interference with the machining station nor its parameters, therefore enabling rapid and easy implementation into industrial practice.

Having analyzed the modern methods of improving the quality and productivity of the cutting edge of the metal cutting tool, on the example of the drill, the method of magnetic abrasive treatment was chosen. This method has allowed to achieve a significant improvement in the quality of the cutting edge (roughness), an increase in the hardness of the surface layer and, respectively, the period of drill firmness. In the dissertation the ways of solving the problem of instrument stability during work are analyzed, the process of MAO is investigated by carrying out operational tests of the drills processed by this method. Magnetically-abrasive powders were selected in the light of previous work in this field, namely, the use of powders of large fractions. The results of the studies confirmed the feasibility of their use, along with small fractions powders. Experimental data were used and implemented at the enterprise "Kyiv Armored Plant".

This thesis presents the application of topology to machining at the micro and macro levels through an experimental study, modeling and analysis. Uncoated carbide tools of four different cutting edge radii and four different feed rates are used to perform orthogonal machining on AISI 1045 steel disks. The study analyzes the cutting forces, changing grain boundary parameters, micro-hardness, temperature and correlates them to the residual stresses that hold a key to the product life. This analysis helps to understand and evaluate the aspects of grain boundary engineering that influence the fatigue life of a component. The two components of residual stresses (axial and circumferential) are measured, and are correlated with the different cutting edge radii and feed conditions. A topology-based modeling approach is applied to study and understand various outputs in the machining process. The various micro and macro topological parameters that influence the machining process are studied to develop a model to establish the effects of topological parameters in machining using Maple program.

Diamond coatings have been increasingly extended to cutting tool applications for machining advanced materials such high-silicon aluminum alloys. Diamond coating tool behaviors are interrelatedly influenced by both the coating and subsequent machining, and yet the tool edge geometry strongly impacts the stress fields around the cutting edge during each process. To effectively use diamond coating tools, it is necessary to understand the stress modifications around the tool edge due to the deposition and during machining. In this study, finite element modeling was applied to simulate deposition stresses from coating and stress modifications due to subsequent machining affected by the edge radius. The results are summarized as follows. For deposition stresses, edge sharpness causes significant stress concentrations around the edge radius area. In machining, the thrust forces increase drastically with the increased edge radius, while the cutting forces increase only marginally. During machining, the thermal load, which causes stress reversal conditions, is more dominant to stress evolutions than the mechanical load. For all cutting conditions tested, increasing the edge radius results in increased stress reversal. The edge radius effects on stress reversal are more prominent at small uncut chip thickness and high speed, which is due to more pronounced size effects and high cutting temperatures. Though large edge radii reduce the deposition stresses, the reduction seems insufficient to compensate the added machining loads within the range of edge radii studied.

Cutting temperature plays an important role in micro-scale cutting process because the dimension of the micro-milling cutter is relatively small and the wear of micro-milling cutter is sensitive to temperature. Considering the sidewall of a groove is formed by main cutting edge of the tool, and the bottom of a groove is formed by tool tip and the edge on the end of the tool. Therefore, effects of tool nose corner radius and main cutting edge radius on cutting temperature in micro-milling process cannot be ignored. However, few studies have been conducted on this issue. The effects of tool nose corner radius and main cutting edge radius on cutting temperature is investigated. A three-dimensional micro-milling Inconel718 model is established by using the software DEFORM3D. And the influence of tool nose corner radius and main cutting edge radius on the size and distribution of cutting temperature are studied by numerical simulation, which is verified by experiments. The work provide reference for the control of the size and distribution of the cutting temperature during micro-milling process.

Temperatures of the carbide tip’s surface when turning stainless steel with a chamfered main cutting edge nose radius tool are investigated. The mounting of the carbide tip in the tool holder is ground to a nose radius as measured by a toolmaker microscope, and a new cutting temperature model developed from the variations in shear and friction plane areas occurring in tool nose situations are presented in this paper. The frictional forces and heat generated in the basic cutting tools are calculated using the measured cutting forces and the theoretical cutting analysis. The heat partition factor between the tip and chip is solved by the inverse heat transfer analysis, which utilizes the temperature on the P-type carbide tip’s surface measured by infrared as the input. The tip’s carbide surface temperature is determined by finite element analysis (FEA) and compared with temperatures obtained from experimental measurements. Good agreement demonstrates the accuracy of the proposed model.

Abstract A finite element model is developed for the simulation of orthogonal cutting of ductile material with blunt-edge tools. The model assumes the machining process as a quasi-static process, is capable of performing the coupled thermal-mechanical analysis, and adopts the continuous remeshing techniques. Based on this model, as well as the material property data of a low-carbon steel obtained from previous researches, orthogonal cutting process with blunt-edge tools is thoroughly analyzed. The analysis focuses on strain and stress distributions, deformation zones, chip flow characteristics, and cutting forces with the variation of process parameters such as uncut chip thickness and edge radius. Due to the computational load, thermal effect is not incorporated in the analysis. Some critical issues, such as chip stagnation point and recovery after ploughing, are investigated. It is found that uncut chip thickness and edge radius have some important influences on the strain and stress values, the shapes of deformation zones, and the cutting forces. The chip stagnation point has a consistent position on the cutting edge when the ratio of uncut chip thickness to edge radius is between 0.7 to 5. The recovery from ploughing is not significant. The intent of the study is to improve the basic understanding of the cutting process with blunt-edge tool for more precise modeling in the future.

In this paper, FEM is employed to investigate the effects of nose radius and edge radius on the turning of AISI4140. The tool material used is Carbide and Johnson-Cook plastic model is employed to model the workpiece due to its capability of modeling large strains, high strain rates, and temperature dependent visco-plasticity. Different nose radii and edge radii are used to explore the effects of the nose radius and edge radius on the machining temperature, cutting forces, and power. This model provides a fundamental understanding of cutting mechanics of the turning operation of AISI 4140.
