Abstract: The main purpose of the research is to study the floating chips produced during mechanical processing. Chips derived from aluminium material cause several difficulties in mechanical processing. Research shows that floating chips clog filters in chip conveyors, resulting in significant downtime in production processes. In this article, cause-effect research has been carried out to find approaches to solving this problem.

Abstract: In the current industrial environment, products’ life cycles have become shorter and the need for more sophisticated molds with free-form surfaces has drastically increased. However, the polishing process of a product needs the exceptional skill of an experienced master. It is difficult to increase productivity if the manually operative process is not automated. So, the main objective of this project is to reduce manpower and time consumption of the polishing process in the industry. Which leads to increases in the productivity rate. This project deals with the automation of polishing work by the use of an industrial mechanical arm with a conveyor. Since polishing work, which takes much time, requires experience, patience, and skill, it is manually performed by skilled workers. This project aims at rationalizing such difficult polishing work by introducing a mechanical arm with conveyor and CAD technology. The arm can be equipped with a polishing tool, i.e., Buffing wheels, also known as mops, are either made from cotton or wool cloth and come bleached or unbleached. In addition, the project is to achieve a robust process that results in a consistent surface finish, the roughness of which can be specified and controlled.

Abstract: This work addresses the challenges associated with the development of short neutral sections (SNS) for overhead lines of high-speed moving trains. A crucial function of a short neutral section is to provide electrical isolation between the different phases of AC traction. These sections are typically located in proximity to the traction substation and sectioning posts. The current SNS design presents several issues, including pantograph arcing, wear and tear of the overhead line system, and the need for manual rotation during periodic maintenance. To address these challenges TRIZ is used, a problem-solving methodology that leverages inventive principles to generate innovative solutions. The work outlines the use of several TRIZ tools and techniques, including the Interaction Matrix, Functional Analysis, Function-Body Diagram (FBD), Trimming, and the Contradiction Matrix [1]. With the application of these tools, the author presents several potential solutions for improving the SNS design to eliminate periodic maintenance and services. One proposed solution involves the use of a segmented overhead line system with an insulating cylinder-shaped discrete insulator to ensure smooth contact of the pantograph. Another solution involves the use of a twisted strip-based insulator to replace linear motion with rotating movement, eliminating the need for manual rotation. The work emphasizes the importance of considering various factors, such as design, material, wear rate, maintenance, and creepage distance, when evaluating the feasibility of these solutions. By leveraging TRIZ to generate innovative solutions, the author demonstrates the potential of this methodology to drive innovation and overcome complex challenges in the development of short neutral sections for high-speed rails.

Abstract: The supporting structure of conveyor in a coal power generation plant located in marine environment, was experiencing severe filiform corrosion. The structure has been used since 2009. This supporting structure holds the conveyor for coal transportation from the ship to the turbine. From visual inspection, it was clearly seen that around 80 % of total area of the structure has been corroded, which influenced the strength of the structure. Hence damage evaluation of supporting structure was important to be carried out to determine the level of damage and to give the recommendation for repairment strategies. The damage evaluation method consisted of thickness measuring, chemical composition test, hardness test, microstructure analysis using replica technique and deposit analysis using SEM-EDS. The result showed that the type of material structure was AISI 1020. The highest reduction in measured thickness was 44 %, which occurred dominantly on bottom and top flange of the structure. It was also found that in some joint areas, the material was perforated. The deposit analysis using SEM EDS found that the type of coating used on steel structure was not suitable for the marine environment.

Abstract: Magnesium MgO exists in nature in large quantities as magnesite (MgCO₃) and dolomite (CaMg (CO₃)₂), and in lesser amounts than oxide in the form of mineral called periclase. Magnesite refractory material containing MgO may be obtained from the high purity magnesite ore simple purification and subsequent calcination at a temperature of 500-700 °C.

Abstract: The conveyer belt is a major component of the conveyor , whose cost accounted for half of the of the entire cost of the conveyor. The loss of the conveyor is mainly due to the use of friction and wear generated in the process, so study on the friction characteristics is very meaningful. The friction and wear of the conveyor is one of the factors affecting their life. Therefore, conducting applied research on belt conveyors and mechanical analysis becomes increasingly important. In this paper, some qualitative research on the mechanical properties is carried out, starting from the application of the conveyor belt.
