Abstract:

This workpiece process is: to find out how to transfer images from Auto CAD software to the Q plus CELL Milling Cnc software, and to find out how to transfer programs from the CNC Milling QELL KELLER software to the TU 3A CNC milling machine. The making of this workpiece uses three main media, namely Auto CAD 2000 software, CNC Milling KELLER Q plus software, and TU 3A CNC milling machine. The process of making the workpiece starts from making the workpiece design in Auto CAD software which is then stored on the CDR via DFX data. The design of the workpiece contained in the CDR is then transferred to CNC Millling KELLER Q plus software via Geometry. in Geometry, the design of the workpiece is dimensioned. Completed from the Geometry the workpiece design is included in the Work plan to be processed so that it can be simulated to move to a CNC program to convert the graphical language into a numeric language so that it can be read by a CNC machine. The programming results from the CNC KELLER Q plus software are then recorded to be executed on the CNC TU 3A milling machine to obtain the workpiece in accordance with the design in AutoCAD. Programming results from CNC Milling KELLER Q plus software cannot be directly used on the TU 3A milling machine (EMCO), because the programming language used is different. Programming language in CNC Milling KELLER Q plus software uses the DIN 66025 standard, while the CNC TU 3A (EMCO) milling machine uses ISO standards, so it needs to be converted first.

Abstract:

In milling operation, Computer Numerical Control (CNC) milling machine has been recognized as one of effective solutions for high productivity, efficiency, and precision. However, the existing CNC milling machine has contributed to ergonomics-related problems such as awkward working posture. The aim of this study is to redesign the existing CNC milling machine by considering working posture of the machinist. This study performed questionnaire survey to determine ergonomics feature requirements from the machinist. The requirements of the machinist are then translated using Quality Function Deployment (QFD) to obtain technical specifications of new design CNC milling machine. The working posture of machinist during operating the existing CNC milling machine and the redesigned CNC milling machine was assessed using Rapid Upper Limb Assessment (RULA). Based on the analysis, the redesigned CNC milling machine has improved the working posture as shown by low score of RULA. This study concluded that by considering the ergonomics feature requirements to the design of CNC milling machine enabled the machinists to perform milling operation in safe working posture. This study suggests that environmental factors should be considered in the future research works.

Abstract:

CNC machine tools are currently predominating in the machine-building industry. Generally, these machine tools are equipped with control systems supplied by the world's leading manufacturers, such as Siemens, Fanuc or HeidenHein, and are very expensive. In parallel, many cheap amateur and semi-professional CNC machine tool solutions are being developed. Below, a CNC milling machine of welded construction is described, which is intended to be, at the same time, a test stand. The design of the milling machine is based on steel closed sections of a large cross-section and a big wall thickness. This has allowed a rigid frame structure to be obtained. To obtain high displacement accuracy, high-accuracy profiled rail slideways have been used, along which pre-stressed linear ball bearings move. The machine tool has been furnished with a fourth numerically controlled axis, which is demountable.

Abstract:

During the technological development, some equipments remain mostly the first days design besides most of others change repeatedly. CNC Milling machines spindle design is one of these which remains mostly the same. With the existing design, in order to obtain the desired torque for metal milling process, the body of the spindle is made huge and heavy which causes the whole machine body to be constructed huge and heavy. In this study a new approach to CNC Milling Machine Spindle Design is made. The design changes the hob to be held indirectly instead of to be held directly at the lower end of the spindle. The huge spindle motor is fixed to the ceiling over the machine and a flexible steel rope is used to transfer the rotational motion. At the end of the steel rope, a planetary gearbox is fixed which is also fixed to the mobile part of the CNC construction. By this way, the required torque is obtained just at the milling process takes place and the motion transmission parts can be made light in weight like the whole construction would be made.

Abstract:

Minimizing cost and optimization of nonlinear problems are important for industries in order to be competitive. The need of optimization strategies provides significant benefits for companies when providing quotes for products. Accurate and easily attained estimates allow for less waste, tighter tolerances, and better productivity. The Nelder-Mead Simplex method with exterior penalty functions was employed to solve optimum machining parameters. Two case studies were presented for optimizing cost and time for a multiple tools scenario. In this study, the optimum machining parameters for milling operations were investigated. Cutting speed and feed rate are considered as the most impactful design variables across each operation. Single tool process and scalable multiple tool milling operations were studied. Various optimization methods were discussed. The Nelder-Mead Simplex method showed to be simple and fast.

Abstract:

Manufacturing of dies has been presenting greater requirements of geometrical accuracy, dimensional precision and surface quality as well as decrease in costs and manufacturing times. Although proper cutting parameter values are utilized to obtain high geometrical accuracy and surface quality, there may exist geometrical discrepancy between the designed and the manufactured surface profile of the die cavities. In milling process<br>cutting speed, step over and feed are the main cutting parameters and these parameters affect geometrical accuracy and surface quality of the forging die cavities. In this study, effects of the cutting parameters on geometrical error have been examined on a representative die cavity profile. To remove undesired volume in the die cavities, available cutting strategies are investigated. Feed rate optimization is performed to maintain the constant metal removal rate along the trajectory of the milling cutter during rough cutting process. In the finish cutting process of the die cavities, Design of Experiment Method has been employed to find out the effects of the cutting parameters on the geometrical accuracy of the manufactured cavity profile. Prediction formula is derived to estimate the geometrical error value in terms of the values of the cutting parameters. Validity of the prediction formula has been tested by conducting verification experiments for the representative die geometry and die cavity geometry of a forging part used in industry. Good agreement between the predicted error values and the measured error values has been observed.

Abstract:

Para o ensino em cursos relacionados à mecânica são fundamentais aulas teóricas e práticas de programação em máquinas CNC. Um grande incentivo para o aluno é ver sua programação transformada em uma peça que possa ser manuseada. Porém, dado o seu alto investimento, muitas escolas técnicas, de tecnologia e engenharia não disponibilizam máquinas CNC para os alunos. Desta forma, é apresentado neste trabalho o desenvolvimento de uma fresadora CNC de baixo custo. Com o emprego do método de combinação de variantes e o método de análise morfológica, os elementos mecânicos para o projeto da fresadora foram selecionados. Assim, foi possível desenvolver o conceito desse equipamento e fazer a estimativa de seu custo. Com a aplicação de análise de valor, utilizando as técnicas FAST, de Mudge e COMPARE, foi possível avaliar pontos críticos que acarretam em custos desnecessários. Com isso, pode-se avaliar como trabalhar com a transferência de recursos.<br>Courses related to mechanical sciences must offer to their students theoretical and practical lectures on CNC machine programming. The possibility of viewing the transformation of a programme in to a manageable part constitutes an incentive to the students. A CNC machine is an essential piece of equipment for such practical classes. A number of schools cannot have a CNC machine because of its high cost. Thus, in the present work, the development of a low-cost CNC milling machine as an alternative for academic purposes is presented. For the selection of the mechanical elements of the CNC machine, a combination of variants method and morphological analysis was used. Then, the design concept was carried out and its cost estimated. Using the value analysis through the FAST, Mudge and COMPARE techniques, the critical points that could increase unnecessary machine cost were examined. It was possible to assess how to work with the resources transference.

Abstract:

Thesis (M. Tech. (Design and Studio Art)) -- Central University of Technology, Free State, 2014<br>This quantitative research project investigates the utilization of emerging technologies within the arts with a view on establishing an interdisciplinary approach between ceramics and engineering. The traditional manufacturing method of producing master moulds is a time-consuming process for the studio ceramicist. This study explores whether computer-aided design (CAD) and computer numerical control (CNC) milling can accelerate the design and manufacturing process when developing master moulds as an alternative to using traditional methods. It investigates whether SolidWorks® can be applied as a suitable CAD design tool for the creation of ceramic vessel forms in order to reduce the design development time frame. It furthermore investigates whether CNC milling can be used as a viable manufacturing technology for the making of vessel prototypes and master moulds from CAD data, the overall objective being to improve and accelerate the plaster of Paris master mould manufacturing process for the batch production of studio-based ceramic artefacts. Findings from this study indicate that emerging technologies have a lot to offer the artist when it comes to providing new possibilities for the creation of artefacts and that SolidWorks® and CNC milling can be utilized as a viable interdisciplinary manufacturing approach between ceramics and digital manufacturing technologies.

Abstract:

This paper describes our work on analyzing and modeling energy consumption in CNC machining with an emphasis on the geometric aspects of toolpaths. We address effects of geometric and other aspects of toolpaths on energy consumed in machining by providing an advanced energy consumption model for CNC machining. We performed several controlled machining experiments to isolate, identify, and analyze the effects of various aspects of toolpaths (such as path parameters, angular change, etc.) on energy consumption. Based on our analyses, we developed an analytical energy consumption model for CNC machining that, along with the commonly used input of material removal rate (MRR), incorporates the effects of geometric toolpath parameters as well as effects of machine construction when estimating energy requirements for a toolpath. We also developed a simple web-based software interface to our model, that, once customized for a particular CNC machine, provides energy requirement estimates for a toolpath given its G/M code. Such feedback can help process planners and CNC machine operators make informed choices when generating/selecting toolpath alternatives using commercial CAM software.

Abstract:

Straight bevel gears are usually manufactured with various machines and systems, and the tooth profiles are produced by grinding or machining by means of a tool with many cutting edges. In recent years, the straight bevel gear has been manufactured by an end mill using a CNC milling machine because the use of the auxiliary apparatus, special cutters, and special machine tools are not needed. Using this method, the gear manufacturing with high accuracy is important problem. In this paper, the coordinate measurement of the straight bevel gear manufactured in this method is performed and the gear accuracy is evaluated. The tooth profiles of a straight bevel gear generated by a quasicomplementary crown gear instead of a conventional complementary crown gear is introduced. For this study, first the tooth profiles of the straight bevel gear were modeled using a 3D-CAD system and the gear was manufactured by an end mill using a CNC milling machine based on a CAM process. Afterward, the coordinates of many points on the gear tooth surfaces were measured at random using a coordinate measuring machine. This coordinate measurement provides the information about the factors relation to the gear accuracy such as pressure angle, tooth angle error, root cone angle, and apex to back and so on. Therefore, the values of the above factors were estimated and were compared with the theoretical ones, respectively.

Abstract:

To pursue high performance 5-axis CNC milling in industry, it is crucial to simulate each specific mill process in high fidelity beforehand, which should model the machined surfaces and predict the cutting forces in the process planning. However, the kernel technique, representation of the un-deformed chip geometry removed by cutter in 5-axis milling, is far from mature. Aiming to solve the problem, this paper presents a generic approach to representing un-deformed chip geometry mathematically in 5-axis CNC milling. The unique features of this research are: (1) the machine tool kinematics chain is investigated and a 5-axis CNC interpolation algorithm is adopted to establish the tool kinematics model, and (2) the closed-form equation of the un-deformed chip geometry representation is derived based on the machined shape being the envelope of a group of ellipses. This approach can model a machined surface with high accuracy and efficiently, and can be used to evaluate the machine surface quality and machining parameters. It can greatly promote the technique of high performance 5-axis CNC milling.

Abstract:

Abstract The normal curvature approach model is a new milling method of machining complex freeform surfaces presented in this paper based on 5-axis CNC machines. For this milling model, its key is to optimize the CL-data of whirlwind milling tool so that the symmetric rotational surface, which is generated while the whirlwind milling tool rotates, can closely approach to the surface being machined. Then, this method evidently raises the material removal rate at the point of contact and efficiently improves the machining productivity. In the paper, a new-typed whirlwind milling tool with standard-sized circular cutters is introduced, and a special 5-axis CNC horizontal bed-typed milling machine is used in manufacturing the freeform surfaces. The tool path generation algorithm about normal curvature approach milling method and its typical examples are analyzed in detail.

Abstract:

Process planning for parts made on CNC machines is usually performed in sequence and carried out without feeding back information about the fabrication process to the planning stage. Shifting planning capabilities to the machine level enables consideration of direct machine feedback. In this paper a method for feature decomposition and tool path planning for pocket milling on a 3 axis milling machine is presented. Based on standard computerized numerical control (CNC) technology, G-code is transferred to the fabrication machine whereat adaptation of processing parameters can take place within a feature. In order to enable a feedback loop from the processing to the planning stage, subfeature elements are defined. Interrelations between subsequent elements are identified and standardized with regard to the manufacturing needs to realize fully machined features. For each element a tool path is generated and translated into valid G-code. After fabrication of each subfeature element processing parameters can be improved. The presented method is implemented in a prototype software tool based on an open source CAD/CAM/CAE kernel and extends an existing open source CAM software framework.

Abstract:

A computer numerically controlled (CNC) milling center is a machine tool for the production of parts with planar, cylindrical and shaped surfaces. The milling center analyzed here includes an open frame — a structure resembling the shape of the letter C. The main cutting motion is performed by a tool clamped in the spindle. Secondary motion can be linear, rotary or a combination of these. Linear movements in three axes are performed by the tool by means of linear motion components (i.e. motion screws and linear guide rails). Rotary motion is performed only when the workpiece is clamped to the rotary table which is mounted on the mounting plate. The basic demands placed on the structure of a milling center include high static and dynamic stiffness during machining processes. This article is primarily aimed at evaluating the response of the frame of the CNC milling machine to the excitation caused by the fluctuation of cutting forces due to step changes in the number of engaged cutting edges. To ensure optimum machining conditions it is important to set suitable cutting conditions for a frame structure with sufficient stiffness. Unsuitable cutting conditions and low stiffness of the machine frame may lead to dimensional inaccuracies of the workpiece, to decreased quality of the machined surfaces or even to the destruction of the tool cutting edges. The aims of the study include the determination of the static deformation, modal analysis to assess the dynamic properties of the frame, and harmonic response analysis, taking into consideration the amplitudes of the loading forces specified in accordance with the recommended operating conditions of the individual tools. Finite element method (FEM) analyses of the frame were performed using MSC.Marc software. Due to the high structural complexity of the computer aided design (CAD) model, the computational model for the FEM analysis had to be simplified. Only the major structural parts and the connecting parts were meshed in detail, combining both structured and unstructured mesh. Geometrically complicated cast parts with large changes of thickness were meshed with linear tetrahedral elements (tetra4) with full integration. Rotationally symmetrical parts, plates and linear guide rails components were meshed with linear brick elements (hex8) with full integration. The overall number of elements was approximately 1,400,000. Tools, including the clamping head and the spindle, are represented by approximate meshes of brick elements. However, a detailed FEM model of the spindle and the tool would be needed for the analysis of the self-excited oscillations during machining, which is the subject of a large number of scientific publications. Increased attention was paid to the incorporation and set-up of the springs between corresponding pairs of nodes of the meshed linear motion components. As a computational model for modal and harmonic response analyses needs to be strictly linear, only linear elastic material properties and linear springs were defined in the analyses presented here.
