Abstract (sommario):

The magnetic abrasive finishing (MAF) process is an ultra-precision surface finishing technology. In order to further improve the finishing efficiency and continuity, a magnetic abrasive finishing process using the circulatory system to renew magnetic abrasive slurry was proposed. This study investigated the mechanism of the compound magnetic finishing fluid in the process using the conveyor belt as the carrier to complete the circulation and finishing through simulation and theoretical analysis. The influence of the different distribution states of the magnetic finishing fluid in the conveyor belt and the finishing area on the finishing characteristics is observed and analyzed, in addition to a series of experiments to explore the feasibility of finishing polychlorotrifluoroethylene resin plate through this process. Experimental results show that as the working gap decreases, the distribution width of compound magnetic finishing fluid on the conveyor belt becomes larger, and the distribution of the points of action on the workpiece in the finishing area is significantly different and the area increases, and obtains a higher finishing force and finishing efficiency. In this study, the surface roughness of polychlorotrifluoroethylene resin plate was improved from 274 nm Ra to 34 nm Ra within 15 min.

Abstract (sommario):

The compressor blade is the key components of the aero-engine to seriously impact the air dynamic performance. However, components with complex designs specifications might pose manufacturing challenges especially when finishing processes are needed to enable their compliance with tight industrial standards for workpiece surface integrity. Information on polishing processes for such sensitive industrial applications is scarce. The paper reports on the influence of polishing methods on the surface integrity of compressor blade obtained after different polishing methods. The research focuses on identifying an “optimised” polishing method for different area that will enable finishing the compressor blade. Two (belt; bob) polishing methods have been tested to address the overall finishing of compressor blade. Although significant differences in tool life performance exist between belt and bob polishing methods, both are capable to meet the requirements of minimum workpiece surface coverage if “optimised” operating parameters are employed. This is proved that belt and bob polishing methods can be employed to enable automated overall finishing of compressor blade.

Abstract (sommario):

One of the most important properties of the surface of wood-based panels is their roughness. This property determines the way of working with the material in the processes of gluing and surface varnishing. The aim of this study was to determine the effect of various sanding belt configurations and the feeding speed of the conveyor belt during grinding on the surface roughness of high-density fiberboards (HDF). The research material was prepared under industrial conditions. Three types of boards were selected for the tests. After grinding, the roughness parameters were measured both transversely and longitudinally relative to the grinding direction, using a Mitutoyo SJ-210 profilometer and the optical method. Based on ANOVA analysis of the data, it was found that the type of HDF boards used and the configuration of the abrasive belts had a statistically significant impact on the roughness. The samples for which the grinding process was performed with sanding belts of the highest grain size had the lowest roughness. For the amplitude roughness parameters, the direction of roughness measurement had a significant influence. These results may provide valuable guidance for the furniture industry in the preparation of HDF for furniture production.

Abstract (sommario):

The aerospace industry still relies on manual processes for finish applications, which can be a tedious task. In recent years, robotic automation has gained interest due to its flexibility and adaptability to provide solutions to this issue. However, these processes are difficult to automate, as the material removal rate can vary due to changes in the process variables. This work proposes an approach for automatically modeling the material removal process based on experimental data in a robotic belt grinding application. The methodology concerns the measurement of the removed mass of a test part during a finishing process using an automatic precision measurement system. Then, experimental models are used to develop a control algorithm for continuous material removal that maintains a uniform finishing process by regulating the robot’s feed rate. Next, the results for various experimental material removal models under different process conditions are presented, showing the process parameter’s influence on the removal capacity. Finally, the proposed control algorithm is validated, achieving a constant material removal rate.

Abstract (sommario):

The belt-finishing process is a recent manufacturing technique in industry, the mechanisms and characteristics of which have not yet been fully explained. This paper attempts to make a contribution to the understanding of the consequences of the process on the surface roughness of surfaces prepared by hard turning. Abrasive film wear and contact parameters between grains and surfaces are analysed. The effects and significant interactions of the most influential belt-finishing parameters on the surface roughness are then investigated. It was shown that the applied force and the hardness of the roller have a great influence on the surface roughness. Furthermore, the film feed rate influences considerably the wear of grains and, as a consequence, this parameter has an important impact on the material removal mode and on the surface roughness.

Abstract (sommario):

Electrochemical abrasive belt grinding (ECABG) technology, which has the advantage over conventional stone super-finishing, has been applied in bearing raceway super-finishing. However, the finishing effect of ECABG is dominated by many factors, which relationship is so complicated that appears non-linear behavior. Therefore, it is difficult to predict the finishing results and select the processing parameters in ECABG. In this paper, Back-Propagation (BP) neural network is proposed to solve this problem. The non-linear relationship of machining parameters was established based on the experimental data by applying one-hidden layer BP neural networks. The comparison between the calculated results of the BP neural network and experimental results under the corresponding conditions was carried out, and the results indicates that it is feasible to apply BP neural network in determining the processing parameters and forecasting the surface quality effects in ECABG.

Abstract (sommario):

Polychlorotrifluoroethylene material is used in industry as a material with excellent insulation, impact resistance and acid and alkali resistance. In this study, we used a magnetic abrasive finishing process with renewable abrasive particles to finish the surface of the polychlorotrifluoroethylene resin plate. Magnetic Abrasive Finishing (MAF) process is a technology that uses flexible magnetic brushes to improve the surface quality of materials. The performance of the magnetic brush is a key factor in surface finishing. In conventional MAF finishing, the number of abrasive particles in the magnetic brush is limited, and the position of the abrasive particles is relatively fixed, which will cause the cutting edge of the abrasive particles to gradually become dull and the finishing efficiency gradually decreases. This paper research the characteristics of the MAF process with renewable abrasive particles. This MAF process has a circulating system that uses a conveyor belt to renew abrasive particles. We use the polychlorotrifluoroethylene resin plate as the experimental processing object to conducted finishing experiment. And the surface roughness of the polychlorotrifluoroethylene resin plate is improved from 315 nm to 32 nm through this process.

Abstract (sommario):

In gas turbines and turbo jet engines, high performance materials such as nickel-based alloys are widely used for blades and vanes. In the case of repair, finishing of complex turbine blades made of high performance materials is carried out predominantly manually. The repair process is therefore quite time consuming. And the costs of presently available repair strategies, especially for integrated parts, are high, due to the individual process planning and great amount of manually performed work steps. Moreover, there are severe risks of partial damage during manually conducted repair. All that leads to the fact that economy of scale effects remain widely unused for repair tasks, although the piece number of components to be repaired is increasing significantly. In the future, a persistent automation of the repair process chain should be achieved by developing adaptive robot assisted finishing strategies. The goal of this research is to use the automation potential for repair tasks by developing a technology that enables industrial robots to re-contour turbine blades via force controlled belt grinding.

Abstract. According to the structural characteristics of the blisk, a new adaptive belt tool system for blisk finishing is developed. The pneumatic servo system, which is composed of the cylinder, the servo valve, and the force sensor, is used to control the polishing force. Due to the strong nonlinearity of the pneumatic system, a two-dimensional fuzzy proportion, integral, derivative (PID) controller is developed for the pneumatic force control. The proposed controller adjusts the proportional, integral, and differential parameters of the traditional PID controller in real time through the error and error rate so as to optimize the control performance of the pneumatic system. Compared with the PID control, the steady-state error of the fuzzy PID control is reduced by 0.03 s and the overshoot is reduced by 4 %, which reveals the superiority of the fuzzy PID control algorithm for the nonlinear system. Finally, the experiments of polishing the blisk sample and the real blisk are carried out by the proposed belt tool system. The results show that the polishing process is very stable and the roughness after polishing is less than 0.4 µm, which proves the effectiveness of the proposed new belt tool system and the fuzzy PID controller.

Abstract (sommario):

Abstract The paper presents a practical example of improvement of foundry production systems in terms of post-finishing of nodular iron castings produced in the conditions of bulk production for automotive industry. The attention was paid to high labour-intensive efforts, which are difficult to be subjected to mechanization and automation. The times of actions related to grinding processing of castings in three grinding positions connected with a belt conveyor were estimated with the use of a time study method. A bottleneck as well as limiting factors were specified in a system. A number of improvements were proposed, aimed at improving work organization on the castings post-finishing line. An analysis of work ergonomics at the workplace was made in order to eliminate unnecessary and onerous for the employee actions. A model of production system using the Arena software, on which a simulation experiment was conducted, was drawn up in order to visualize the analysed phenomena. The effects of the project were shown on graphs comparing times, costs, work ergonomics and overall efficiency of production equipment indicator.

Abstract (sommario):

This paper researches on the theory of the crown modification of cylinder-roller bearing raceway using electrochemical abrasive belt grinding (ECABG) technology, and establishes relevant experimental device. The range of processing parameters with a better surface roughness can be obtained through experiments. On this basis, a mathematics model of distribution of material removal of electrochemical machining bearing is set up. Considering the controllability of processing parameters and demand of the surface quality, the processing parameters such as interelectrode voltage, electrolyte, interelectrode gap and cathode geometry are invariable in the experiment, and processing time is changed to control the crown value. The experimental results show that ECABG can enhance the surface quality of raceway to a great degree, and obtain the ideal forming crown at the same time under the optimum technological parameters. This paper developed a new method for the crown processing and finishing of bearing raceway.

Abstract (sommario):

Abstract: Intelligent manufacturing is going to boom in the upcoming years. The characteristic features of Industry 4.0 are fully automated production facilities where all processes are controlled in real-time and take into account the changing external conditions. The core of the Industry 4.0 is made up of digitalization and robotics, in particular, the use of collaborative robots and MES. MES (Manufacturing Execution System) is a specialized system designed to solve the problems of synchronization, coordination, analysis, and optimization of production. It involves the use of conveyor belts for rapid transportation of products. Industries where conveyor belt systems are excelling include automotive, computer, good, packaging, print finishing, bottling and canning, chemical, pharmaceutical, aerospace and food processing The safety conditions in fundamental industrial jobs are dangerous and harmful combined with ineffective manual work as a result of rising need for mass manufacturing. In industries, automation is the use of technology to jobs that were previously handled by humans. It is a potent instrument that can aid companies in enhancing quality, production, and efficiency. A typical type of mechanical handling equipment that transports things from one place to another is a conveyor system. These systems consist of conveyor belts that are designed to work seamlessly with robotic arms and other automated equipment. Increased automation and mass production rate reduces the lead time and increases the profit of a firm. The deployed robotic arms are immensely capable of handling various tasks with increased flexibility. Using a robotic arm with an end effector as a gripper to hold/pick and place the material from the conveyor belt improves the product flow process. The project comes with the NodeMCU firmware and an integrated Wi-Fi chip, the ESP8266 12E. To connect with the controller via a mobile phone, a web page would be constructed using HTML and coded using the Arduino IDE's C language. At either end of the conveyor belt, 2 robotic arms with 2 degrees of freedom (D.O.F.) would be placed. Using one arm to place the product on the belt and a second to pick it up at the other end. Also calculating the analytical data of the system that is involved in reallife industrial processes along with the simulation of entire system for the UR10 industrial robot, using the RoboDK simulation software. Through the usage of this system, productivity is boosted with improved safety of the working environment, become more effective, be more flexible, and have higher levels of job satisfaction

Abstract (sommario):

Purpose The purpose of this paper is to analyse dynamic drape behaviour of eight different types of woollen fabrics each treated by three different finishing processes. Design/methodology/approach A new apparatus was used to evaluate the dynamic drape formation process of woollen fabrics during the rotation of the samples at different speed grades of 0 (static drape), 30, 60, 90, 120, 150 and 180 rev/min for each sample. The computerised image analysis method was used to measure the drape coefficients (DCs). Findings As a result of experiments, it was found that shearing, calendaring, pressing processes affected the drapability and drape behaviour negatively, but belt pressing treatment and decatising process improved the drapability and the drape behaviour for all fabrics. Furthermore, there is a reverse relationship between fabric weight and drape behaviour. As the fabric weight increases, DC value increases due to the increase of fabric tightness. Originality/value To date, although many researchers have studied the static draping behaviour, the studies regarding the dynamic drape behaviour of the fabrics are quite limited to an extent. Besides, none of these studies regarding the drape behaviour have investigated the effects of different finishing processes on the drape behaviour of wool fabrics.

Abstract (sommario):

Conveyor transport at a modern coal mine is the main link that determines the overall performance of the enterprise. For safe operation of belt conveyors, it is important to ensure that shift output per face doesn’t produce average and maximum minute material flows, which exceed strength margin of the belt, power margin of the drive, and receiving capacity. Such situation, as a rule, may arise due to the strive of workers to compensate for underproduction caused by long downtimes of a face for any reason. In the paper, a method is proposed that enables determining the maximum shift output per face. According to the technique described in the “Basic Provisions for Designing Underground Transport of New and Existing Coal Mines,” the average minute material flow, which determines the operational load on a belt conveyor, depends on the material feed time factor. Accepting the assumption that a coal shearer works the entire shift in a face, the limiting value of the material feed time factor is equal to 1. To determine the actual value of this factor, it is proposed to determine the face operating (production) time using actual planogram. The shift time is spent for preparatory and finishing operations, the face equipment and conveyor line troubleshooting and failure recovery, auxiliary service operations and, finally, operational and organizational downtimes. On the actual planogram, these time intervals are displayed by straight-line portions. Thus, the shift time minus downtime for any reason, represents the face production time. The ratio of these values represents the operation factor. Applying the operation factor allows to determine the maximum limiting face production, not only taking into account the volume of coal mined per cycle, but also based on coal cuttability and technical specifications of the face equipment. This enables us to determine the face production load that ensures safe operation of the belt conveyor.

Abstract (sommario):

The improvement of the quality of the surface roughness of the polyurethane board (PB) has always been a challenge in the automotive industry. A suitable combination of the milling parameters is very important in order to get a high grade of smoothness specially when dealing with complex designs such as curved profiles. In this paper, a half factorial design of experiment (DoE) with 16 runs at two levels is applied in the milling operation of the checking fixtures of a car seat belt bracket under a dry cutting condition. The Feed rate, Depth of cut, Spindle speed, Step over and Plunge rate were taken as the variables for the DoE. Two different milling tools, a flat end mill of diameter10 mm for roughing, and a ball nose of diameter 5 mm for the finishing process were used. Minitab software was use to analyze the correlation between the parameters and the surface roughness. The most influential factor in the milling process was observed to be the Step over.
