Abstract:
Study on the load exerted on cutter head is very useful for the design and performance prediction of hard rock tunnel boring machines. A composite model based on smoothed particle hydrodynamics and finite element method was carried out using AUTODYN software to study the rock fragmentation mechanism of constant cross-section disk cutters in cutter head. The normal force, rolling force and side force on the disk cutters with different cutter radius were researched in the numerical simulation study. The results were verified by historical literature data. To obtain the distribution of the forces with different cutter radius, the loading of cutter head of a Ф5.75 hard rock tunnel boring machine were analyzed. The result shows that it is useful for cutter head’s design and its layout optimization.

Abstract:
Full face rock tunnel boring machine (TBM) plays an important role in boring rock of tunnel. The failure of disc cutter is the main reason leading to low efficiency of TBM. In this paper, analysis of force and motion for disc cutter are carried by using ABAQUS to study stress distribution and concentration in disc cutter and rocks. Influence of different rocks on stress in disc cutter is analyzed. By combination the failure modes of disc cutter and its stress distribution, methods of decreasing failures of disc cutter are presented. Wear resistance and service life of disc cutter are improved by matching the materials of disc cutters with rocks. The results are useful for structural optimization and strengthening treatment of material of disc cutter.

Abstract:
To obtain the reasonable layout and structure shapes of the various kinds of cutters in tunnel boring machine (TBM), the kinematic/dynamic of cutter head system was analyzed by using virtual prototype and finite element method (FEM). The velocity and force curves were got from different positions of cutters and the mode vibration of scrapers and cutter hobs were obtained to analyze their structural performances next stage. It is shown that these results can provide references for dynamic optimization design of tunnel boring machine. Therefore, it is necessary to implement kinematic/dynamic analysis and mode analysis before manufacture of production.

Abstract:
This paper is devoted to experimental study of fine boring of steels, which improves performance and parameters of processing accuracy. The conditions that ensure high wear resistance of cutting blades and improvement of accuracy parameters and processing quality were determined by changing cutting conditions and special geometry of carbide cutters with chip-curving chamfers. In the experiments, single-cutter boring was used, as well as double-cutter according to the feed division method. On the basis of the method of planning an experiment in the presence of a large number of variable input parameters, rational values of speed, feed, depth of cut, as well as parameters of roughness, taper and deviations from the roundness of the machined holes are established. The effect of fine boring modes on wear and tool life of cutting edges has been clarified. The influence of the compliance of cantilever boring bars on the level of oscillation of the cutter was also studied. It was found that intense vibrations occur for boring bars of small diameter <10 mm at a depth of cut >0.1 mm, resulting in intensive wear of the cutters. In preliminary experiments, it was found that boring of soft parts (type 20X and steel 30) is significantly different from machining harder steels and requires the use of other cutting conditions. Although the groups of structural carbon, high-quality and alloy steels may differ insignificantly in terms of processing conditions and the results achieved in the process of fine boring, however, for processing steels with special properties, a distinctive feature arises, namely increase in the level of vibrations with increasing cutting speed within the range usually used for other steels. This paper shows results of an experimental study of the process of thin boring of 35L steel with cutters made of TЗ0K4 hard alloy and chip-curving chamfers along the cutting blades.

Abstract:
The force load research of disc cutter can be used in the design of disc cutter, in order to improve the working life, determine when to change another cutter. Based on the working platform of ABAQUS finite element analysis module, single disc cutter rock-breaking of the simulation model is established, and according to the theory of rocks plastic rule, dynamics analysis and dynamic simulation are done when the cutter is in rock-breaking process by which, the added force can be got when the disc cutter and rocks contact each other in different wear conditions of contact force in the process of the dynamic contact each other. The results show that with the cutter damage increasing, the added force is increased and cutters maximum instantaneous stress load is 1.5 ~ 2.5 times than the average stress load, which has a negative influence on working efficiency. To have a clear understand of cutters design and working life and when to change another cutter in working time, the results also offer an engineering parameters for researching the load state of TBM tunneling.

Abstract:
This paper presents a novel model of lay out of cutter head of TBM(tunnel boring machine). Rock-broken mechanism during the operation of the cutter head is analyzed to study the layout of cutters. A model of the cutters under the action of forces during TBM’s working has therefore been developed, thus proposing a scheme to improve the rock breakability of TBM’s cutter head on which the cutters are lay out. Then, a nonlinear multi-objective mathematical model with complex constraints is developed, with an optimization program provided via an intelligent algorithm for the layout design of cutters on the cutter head of a TBM. The cutter head of an EPB6.28 TBM, an optimized design is given to set up a prototype with digitized cutter head, to which a simulation is done for the verification of equilibrium of forces. Comparing analytically the cutter wear and equilibrium of forces between a previous and a newly designed cutter heads, the results shows digitally that the new one is more practicable than the previous one.

Abstract:
By using fracture mechanics theory of rock, the rock fragmentation mechanism of tunnel boring machine (TBM) cutters is analyzed and the analysis of forces of cutter is carried out. A new method to predict disc cutter specific energy for TBM is developed in this study. By using the dynamic models of TBM cutters interaction with the rock, specific energy prediction model for TBM cutter head is developed. The data from the actual tunnel construction is analyzed by using an example of Qinling tunnel and the comparison is made with the field data. The results indicate that the model developed in this study could not only replace the experiment to disc cutter specific energy for TBM, but also provide a theoretical basis for the performance prediction and optimal design of cutter head for TBM.

Abstract:
Rock tunnel boring machine is one of the main machineries and equipments for underground engineering, and the failure of tool systems is its main failure form. Rock hob test-bed is the only testing equipment for tool failure and wear. In this paper, the breaking rock by the double disc cutter is simulated and four kinds of rocks are selected to test the influece of rock characteristics and spacing between two disc cutters on the rock breaking by the double disc cutter test-bed. The results show that there is different optimal spacing between two disc cutters for different rock; the optimal spacing is inversely proportional to the hardness of the rocks; the maximum stress appears the boundary between the disc cutter and rock.

Abstract:
Changing the cutter is an essential procedure in tunnel boring machine (TBM) operations. The danger and low efficiency of manually replacing the disc cutter has led engineering equipment designers to study technologies to automate the changing of cutters. The key step is to design a new integrated disc cutter (simplifying the replacement process) to facilitate robot operation. Until now, the design and research of new integrated disc cutter systems has mainly relied on inspiration. In this paper, a solution space of a certain configuration of an integrated disc cutter system based on topology theory was designed. The evaluation system for the solution space was constructed by the analytic hierarchy process (AHP), and the optimal scheme of the configuration was finally obtained. In addition, experiments and simulations show that the structural strength and anti-loosening performance of the new disc cutter system meet the engineering requirements. Application of topology theory and the new evaluation system provides useful theoretical analyses and guidance for the design of new cutter systems.

Abstract:
The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg. The available space in the tunnel is very limited which puts strict requirements on the size of the service equipment.A specification of requirements was set up based on the background study made in the Master Thesis. Concepts to solve the problem were then generated and evaluated against each other.A concept consisting of a wagon with three slots for disc-cutter transport, a foldable crane with a hoist and a lifting tool adapted to the disc-cutters were chosen for further development. Since the concept was quite extensive the decision was made to focus the work around the lifting tool.By loading new disc-cutters onto the driven wagon together with the foldable crane and the lifting tool, the equipment can be transported past the machine in the tunnel and the crane can then be set up in front of the machine's cutter-wheel. The lifting tool is then lifted by the hoist to enable the disc-cutters in the cutter-wheel to be replaced.The lifting tool consists of two claws that close around the disc-cutter to fixate it geometrically and a counter weight to enable easy positioning of the disc-cutter by hand. The lifting tool is dimensioned according to two different load cases and was verified by FE-analysis.Recommendations for future work and more detailed design were set up.
Examensarbetet denna rapport baseras på, har utförts i samarbete med Svea Teknik AB. Svea Teknik är ett konsultföretag som på uppdrag av Atlas Copco utvecklar delar av en gruvmaskin för tunnelborrning. Maskinen konstrueras för att mekaniskt krossa berget genom att fixera sig i tunnelgången och pressa ett stort skärhjul utrustat med diskformade s.k. kuttrar mot bergväggen samtidigt som skärhjulet roterar. Då kuttrarna är de verktyg som står i direkt kontakt med berget slits de markant och måste bytas ut för service med jämna mellanrum.Detta examensarbete har syftat till att utveckla en serviceutrustning för att möjliggöra snabba och smidiga byten av dessa kuttrar som har en diameter på 17 tum och väger ca 130 kg. Då utrymmet i tunneln är väldigt begränsat finns stora krav på utrustningens storlek.En kravspecifikation, baserad på examensarbetets bakgrundsstudie, utarbetades för att ligga till grund för de genererade koncept som sedan utvärderades gentemot varandra.Efter att ett koncept bestående av en transportvagn med plats för tre kuttrar, en vikbar kran med telfer samt ett specialanpassat kloförsett lyftverktyg hade valts togs beslutet att fokusera arbetet kring lyftverktyget för att begränsa projektets omfång.Genom att lasta nyservade kuttrar på den drivna transportvagnen tillsammans med den hopvikta kranen och lyftverktyget kan den ledas fram förbi maskinen i tunneln och kranen monteras upp framför maskinens skärhjul. Lyftverktyget hängs sedan upp i kranen för att möjliggöra att kuttrar lossas respektive monteras.Lyftverktyget består av två klor som sluts runt kuttern för att fixera den formbetingat samt en motvikt för att för hand kunna ändra rotationen av verktyget kring infästningspunkten. Lyftverktyget dimensionerades utifrån två uppsatta lastfall och verifierades sedan med FEM-analyser

Geometric-mathematic models, which specify the effect of cutting edge angles, cutting element edges radius and the profile roughness height feed according to ten points, have been developed. Basing on the experimentally testified feed stochasticity on the VSCL, which are subject to the normal distribution law, as well as the geometric-mathematic models of the profile roughness height parameters of the method of its estimation has been proposed. Basing on the geometric-mathematic and probability-mathematic models the principles of the construction design of multi-cutters metal cutting tools (MMT) with the asymmetric location of cutters, that is, three- and four-cutters boring heads, which operate in simultaneous distribution of tolerance and feed mode, in which one rough and two or three finishing cutters correspondingly are used, have been developed, as well as special four-tooth countersinks with the pair-asymmetric location of cutters operating according to the feed distribution scheme. General construction characteristic of the proposed MMT is the corrected guting edge angles on the cutting elements. Dependences for finding their technological (feed and cutting depth on every of cutting elements and the feed on revolving) and design (central angles of mutual location of cutting elements corrected angles) parameters, have been proposed. For four-cutters boring heads the model of the angles value optimization has been presented, providing the maximum efficiency of machining. The options of these MMT designs have been presented, which had been applied at the joint venture «Kamianets-Podilskautoagregat». The analysis of the available methods of investigation has been carried out as well as the estimation of the power characteristics of the machining process and the roughness of the machined surface deep holes. Experimental equipment for testing the power characteristics of the MMT deep holes machining has been developed, special chuck in particular, for fixing thin-walled blank – hollow cylinders with deep holes, special dynamo-metric device, and the available device for testing on the screw-cutting lathe of 1M63-type, has been improved. The method of experimental determination of the power characteristics of the MMT deep holes machining with the asymmetric location of cutters taking advantage of the theory of the experiment planning, has been developed. Taking into account the feeds stochasticity, the empiric dependencies for average values of the axis force and the torque, as well as their maximal values have been obtained. It was found that while machining by the countersinks with the pair-asymmetric location of cutters the axis force is by 15.2% greater and the torque by 22.6% smaller as compared with those in conventional tools. As a result of estimation of the feed effect on the Ra parameter it was found, that the optimal feed for countersinks with the pair-asymmetric location of cutters is the feed s=0.35 mm/rev. The method for finding the economic effectiveness of machining the cylinder deep holes surfaces taking advantage of the proposed engineering solutions, obtained due to the increase of the machining efficiency providing the given values Ra, has been developed. Key words: multicutters metal-cutting tools, asymmetric cutters location, countersink, boring head, cutting edge angles, cutter, feed, cutting depth, roughness.

Abstract:
Uma implementação computacional baseada nos conceitos da mecânica do contato e no Método dos Elementos de Contorno é desenvolvida para simular a interação entre discos de corte e maciço rochosos. Simula-se o contato considerando-se inicialmente uma superfície potencial de contato que é atualizada durante um processo de carregamento incremental, podendo conter elementos separados, em contato sem deslizamento ou com deslizamento parcial. A cada passo do carregamento incremental estima-se a configuração do modelo e os dados obtidos neste passo serão utilizados como parâmetros no passo seguinte até que todo o carregamento esteja aplicado. O modelo em estudo consiste em dois discos de corte paralelos atuando sobre uma base sólida com característica elástica linear. São feitas duas simulações com os discos de corte. Na primeira delas, compara-se a penetração dos discos utilizando-se como parâmetro os valores calculados em uma análise por elementos finitos. No segundo caso, estuda-se a distribuição de tensões no maciço quando se altera o espaçamento entre os discos para um mesmo carregamento. Além desta análise, duas outras comparações são feitas utilizando como parâmetros soluções analíticas e numéricas de modelos clássicos da mecânica do contato. São estes: cilindro e pilar em base elástica.
A computational implementation based on contact mechanics and on the Boundary Element Method is developed in order to simulate the interaction between disc cutters and rock mass. The contact simulation considers initially a potential contact area which is updated during an incremental load process, in such way the surface can include elements in separation, stick or partial slip. At each incremental load step the configuration of the model shall be evaluated and the values computed at such step are used as parameter to the next load step until the end of the loading process. The investigated model consists in two parallel cutter discs on a flat elastic foundation. In the first simulation the penetration of the discs are studied and the results are compared against a finite element simulation. In the second simulation, the stress distribution in the rock mass is evaluated considering different spacing between the disc cutters by keeping the same load. In addition, two benchmark problems of contact mechanics, such as the cylinder and the flat punch on a elastic foundation, were modeled in order to validate the proposed algorithm. The obtained results were compared against analytical and numerical solutions.

Abstract:
Finite element simulations of high-speed orthogonal machining were performed to study the finish hard-turning process as a function of cutting speed, feed rate, cutter geometry, and workpiece hardness. The finish hard-turning process is defined as turning materials with hardness higher than 40 HRC (Hardness – Rockwell C), under appropriate high feed rate and low depth of cut conditions. In the simulations, properties representative of AISI 52100 bearing steel hardened to 45, 51 or 58 HRC were assumed for the workpiece. Cubic boron nitride (CBN), titanium aluminum nitride (TiAlN)-coated carbide cutters, and ceramics inserts are widely used as cutting tool material in such high-speed machining of hardened tool steels — due to high hardness, high abrasive wear resistance, and chemical stability at high temperature. The numerical simulations or experiments assumed physical, mechanical, and thermal properties representative of each of the three cutting materials. Cutting forces, tool and workpiece temperature, and residual stresses were determined in the numerical simulations. These resulting trends in forces, temperatures, and residual stress are consistent with experimental results reported in the literature.
