Abrasive flow machining (AFM) is one of the unconventional methods of finishing surface. The material is removed by the flow of pressurized abrasive paste between the machined surfaces. The use of a flexible tool allows for finishing surfaces with complex geometry. The article presents results of experimental investigation on finishing surface topography of nickel-based super-alloys. Samples were pre-treated by electro discharge machining. The results of the study indicate the possibility of significant reduction of surface roughness after EDM with AFM finishing.

Abstract:
Usually, bigger diameter milling tools were firstly applied in rough machining of NC Milling for improving efficiency and reducing cost before semi-finishing. In order to make the surface of parts more smooth and get accurate dimension parameters and proper shape, it is necessary to select appropriate tools to carry out the finishing of NC Milling. Moreover, higher precision dimension or shapes of parts can be achieve by the method of the semi-finishing, which it can be carried out after rough machining of high efficiency. Currently, the main methods of semi-finishing include semi-finishing of using IPW and semi-finishing of using reference tool.

Abstract:
Continuously increasing of productivity is main cause of finding of new ways and methods of machining. High feed machining (HFM) is one of methods of high-productivity machining developed to achieve higher metal removal rates and decrease machining time. Each machining or treatment operation introduces residual stress into the material and its surface layers. Roughing methods of machining generate tensile residual stress obviously. Tensile character of residual stress is not suitable for functional properties of produced parts. In some cases, finishing methods of machining can improve residual stress to suitable character. New detection method of residual stress by applying of x-ray diffraction allows to measure residual stress as triaxial tensor and distribution of residual stress. When we know analyse the residual stress thoroughly, we can design right finishing method and so improve the character of residual stress. This article is focused on analysing given measuring method of residual stress in triaxial direction and next possibilities of their eventual improvement.

Abstract:
High finishing machining tool path generation methods are usually adopted for five-axis computer numerically controlled machining of sculptured surface parts. The quality of the high finishing machining has an important effect on that of the surface. In this paper, a high finishing machining tool path generation method is introduced to generate an optimal tool path. The initial tool path is firstly created based on the constant scallop height, then the derived tool paths are generated as a kind of the diagonal curve by the initial tool path, and at last, the tool path smoothing algorithm is applied to the generated tool path. This path algorithm can ensure higher level of smooth of the surface been machined. Finally, the results of simulation and experiment of the machining process are given to verify the smooth and applicability of the proposed method.

Abstract:
The present contribution focuses on finishing operations in machining. Finishing operations belong to the most time-consuming and surface quality-critical machining tasks. High-quality tools are available nowadays for choosing optimal tool paths for finishing. Yet, the finishing options for general shaped surfaces are still severely limited. Although CAM systems can efficiently generate tool paths, none of them offers the combination of finishing tool paths, modern productive methods and adaptive tool paths. Increasing the productivity while maintaining dimensional accuracy and the quality of finished surfaces is the key point in finishing. One of the ways to improving productivity is the use of constant cutting speed. The aim of this article is to present experimental verification of these assumptions and demonstrate the impact on the quality of the finished surface

Abstract:
Obtaining to high quality surfaces of industrial parts is an important manner for manufacturing involves. Different finishing process are capable to providing the require surface roughness in most cases, considering that, in some special parts, depending on shape, material and dimension of parts, the prevalent methods are limited, especially in finishing of sculptural and curvilinear surfaces. In this research, a new applied apparatus is represented based on magnetized abrasive grains finishing process. In this way, abrasive grains gathering around a rotational cylindrical tool thanks to a permanent magnetic field and work-piece, which usually is a formed thin metal sheet, located on a rotary table. Therefore, coinciding of those motions providing the require machining forces for finishing of surface without any physical contact between tool and work-piece. Presented process may carry out dry and wet in case of changing the main machining parameters such as: material and size of abrasive grains, tool and work-piece surface gap distance, tool and/or table rotational speed (r.p.m) and work-piece material. The recommended process has remarkable advantages such as: non-contact surface finishing, high finishing of non-flat surfaces, no need to clamping for work-piece because of low machining forces, responsibility for finishing of a wide range of materials except magnetizable parts, low machining costs and easy set up. This method has a lot of applications in production of optical lens, orthopedic prosthetic components and jewellery. For approve of the designed apparatus advantages, relative to other existed MR fluid machining system, some samples of very thin complex formed sheet have been successfully polished.

Abstract:
This paper deals with a new surface finishing method of electrically conductive diamond materials by making efficient use of an electrically conductive nature of the workpiece material, instead of conventional methods such as grinding, lapping and polishing using diamond abrasives. The authors focused on the electrolytic machining method and not on the electro discharge machining method for the two advantageous features of the electrolytic machining in addition to the general view that a better surface roughness could be obtained. One of those features is that no higher heat is generated at the machining point. This can eliminate a risk of the film delamination in the case where a workpiece is the CVD diamond coated tool. The other is that a wider machining gap is available between an electrode and a workpiece. This was thought to allow the electrolytic machining to be applied to a tool with a complex shape such as a drill and an endmill. Based on these concepts, electrolytic machining experiments were conducted on the electrically conductive diamond materials. From the results, it was found that the surface of the electrically conductive diamond could be smoothened enough by electrolytic machining though relatively long period of time was required.

Abstract:
Integrated feature technology promotes a closer connection between design and manufacturing through features. When machining features are determined, they may or may not be readily useable for a process planning system. In a feature-based design system, features in a design model are of design type of features. Further conversion is also needed to arrive at machining features. This chapter starts with a discussion on the issues of interfacing and integration. This is followed by some of the methodologies that can bring feature technologies one step closer to manufacturing processes. Representing a machining feature in terms of its machining volume that can directly corresponds to a specific type of machining operation (e.g. finishing, semi-finishing, and roughing operations) is one of the methods introduced in this chapter. In order to achieve this, a number of machining operations is to be decided. For this, tolerances, surface, finish, and other design information are to be considered. The fuzzy nature of these data and the concerning knowledge means that an appropriate treatment of such information is also needed. A direct way of linking a feature-based design model with machining operations is to map the design features to machining features and perhaps further to the cutting tools that may be used to produce the features.

Abstract:
Abstract 3D printing technology could be extremely beneficial for increasing the flexibly and reducing the cost of carbon fiber reinforced polymer composite (CFRP) production. However, this technology suffers from poor surface quality and uncertain engineering quality. Mechanical finishing processes could concurrently solve these surface issues with the 3D printed composites components. Herein, a mechanical finishing process for 3D printed CFRP composites via CNC milling is proposed to improve the surface quality of two 3D printing methods, namely fused deposition modeling (FDM) and laser assisted-laminated object manufacturing (LA-LOM). The 3D printed CFRP structures fabricated via both methods comprise of continuous carbon fiber reinforcement. The surface roughness and surface morphology of the original unfinished and finished surfaces with various cutting depths are extensively studied to investigate the feasibility of the proposed finishing technique. The surface morphology of the surfaces parallel and perpendicular to the 3D printed layers is the main focus of this work. After the CNC finishing process, the surface roughness of the 3D printed CFRP composites is improved by 70% and 60% for FDM and LA-LOM components, respectively. A smooth, consistent, and predictable surface morphology is achieved for various cutting depths demonstrating a substantial improvement over the original 3D printed surfaces.

Abstract:
Since recent studies have demonstrated the benefits of hard turning over other abrasive machining processes as a finishing process in terms of surface integrity, a strong need has existed to improve the performance of chucking. It is because the poor repeatability and accuracy in the positioning of chucked workpieces became the major bottleneck in the implementation of finish hard turning for precision mechanical components. However, the understanding of chucking has not been adequate, nor has any systematic method been reported for improving chucking accuracy. In this paper, all the major factors that affect the positioning accuracy and repeatability of a chucked workpiece have been identified by error budgeting and systematic measurements. In addition, the characteristics of these factors, as well as their effect on chucking accuracy, were investigated. From the results, a chucking error map that summarizes the relations between these factors and the positioning error of a chucked workpiece was developed. Then, a series of experiments were carried out, based on the results of the earlier works to test the effectiveness of the error budget. The results demonstrated that the knowledge on these factors was accurate and it could be effectively used to improve the positioning accuracy and repeatability of a range of cylindrical workpieces chucked for machining. It was also shown that hard turning alone, without any extra machining process, could satisfy the same level of concentricity which is currently achieved by finish grinding in the machining of different types of cylindrical workpieces. Even if this study was originally intended for the implementation of finish hard turning that can replace finish grinding, the methods developed can be used to improve the final form accuracy of cylindrical workpieces in other finishing processes including grinding if any workholding devices similar to chucks are used to hold the workpieces. The methodology and the procedures for improving chucking accuracy are covered in a pending patent by the authors.

Abstract:
This paper presents a floor-wall and ceiling (FWC) approach to determining the tool axes for five-axis machining. The paper focuses on the pocket floor finishing by using ball-end tool. This FWC method generates tool axes by simply linking the corresponding points between tool location paths on floor and tool axial paths on ceiling. The geometry of the floor, wall, and ceiling of a pocket are first discussed. The construction and manipulations of the tool location paths and the tool axial paths are then addressed. The relationship between the tool axis variation and the manipulations are analyzed such that the generated tool axes are guaranteed to be smooth, optimized, and collision-free. Computer illustrations and example demonstrations are shown in this paper. The results reveal that the FWC method can generate much higher quality tool axes than the traditional methods.

Abstract:
Abstract Automatically monitoring finishing quality by computers can achieve efficient product quality management and can improve overall production efficiency. To be able to offer quantitative measures and to achieve this goal, this paper discusses and suggests the utilization of artificial intelligence (AI) technology to predict product finishing quality by use of signals such as vibrations captured by accelerometers generated during manufacturing. To reduce the cost of inspecting products one by one, a deep one-dimensional convolutional neural network (CNN) is proposed to predict machined surface quality. In this method, dense residual skip-connections are used to improve the complexity of the model to improve the accuracy of predicted values. With the adaptation of the pooling layer in the proposed model, it is observed that the number of parameters used in the model is greatly reduced. Not only the predicted accuracy is optimized with the proposed model, the parameters that need to be stored and the computation resource that is consumed in the inference stage are significantly reduced as well. Compared with methods reported in the literature, through calibrated experimental verifications, the proposed model used in this work can improve the prediction accuracy by 10 percent, without any additional signal preprocessing efforts. The work presented in this paper is thought to have engineering implications in quantifying machining quality in the machine tools industry.

Full text
Abstract:
Electrical Discharge Machining (EDM) is a non conventional machining process capable of accurately machining parts with high hardness and of complex shapes. The sparks produced during the EDM process cause localized melting on the work surface. The formation of recast layer is very common on EDMed surfaces. The recast layer reduces the service life of the die or mould surfaces, especially under fatigue loads. In the present work, Magnetic Abrasive Finishing (MAF) process has been explored as a method to remove the recast layer formed on a EN 31 steel cylindrical specimen machined by EDM. MAF process is one of promising methods capable of removing the material at micro/nano level under gentle mechanical forces. The diamond based sintered magnetic abrasives have been used to machine the EDMed surface. The experimental results indicate that the EDMed surface of EN-31 steel can be successfully finished with diamond sintered magnetic abrasives. On the finished surfaces, no evidence of micro cracks, voids and recast layer has been seen. Moreover, an average improvement in the surface finish up to 80% over the initial surface finish has been obtained. The micro hardness measurement on MAFed surface shows that brittle and hard layer has been removed. SEM photographs indicate the success of MAF for removal of EDMed surface.
