Testing results of a multi-cavity mold for injection molding of MIM 4140 alloy are presented in the article. Recommendations for manufacturing of forming parts of the mold were given. Based on an implemented technological process of casting and subsequent laboratory researches an information was obtained about the condition of a casting (hardness on Super-Rockwell, shrinkage and quality of a surface layer of material before and after heat treatment). Calculated overall dimensions of the forming parts of the project mold will allow making forecast of shrinkage of MIM 4140 alloy after injection molding.
Study of sliding wear rate of hot rolled steel specimen subjected to Zirconia...IJERA Editor
Wear is nothing but loss of material by usage. In a mechanical industry mechanical components will operate
under severe load, temperature and high speeds. Under such a type of situation, when metal to metal contact take
place the surfaces that comes in contact is subjected to wear. These should be considered as a serious affair in an
industry because if the process of wear continues it can reduce service life of the component and also to the
entire mechanical system to which the component has been used. In the light of the above the present work
mainly deals with the study of wear behavior of hot rolled steel with and without zirconia coating on the contact
surface and the effect of zirconia coating with varying thickness.

Tool life is machining data which is related to machining process. The aim of this
research is to determine the tool life, tool wear and Taylor’s tool life equation value of
coated carbide insert when used in turning process of AISI 304 stainless steel. By
completing this research, the tool life of coated carbide insert will be known and can
be estimated when different cutting speed for given feeding speed and depth of cut are
used. The experiment was done by using cutting speed which was varied whereas feed
rate and depth of cut were fixed during the turning process until the tool wear value of
each cutting speed reaches 0.3 mm (VB = 0.3 mm). Taylor’s tool life equation was
obtained as VCTL

The machining process is essential in the manufacturing industry. Among the all
machining process, turning is the broadest techniques used to remove the metal. In
this machining process, metal removal rate was influenced by the sharpness of the
cutting tools. Due to the friction between the workpiece and the tool insert, tool wear
occurs. After the wear takes place, the efficiency of the machine will be reduced and
metal removal time will be increased. Hence, it is essential to investigate the
behaviour of the tool wear under the machining. This investigation is to analyse the
wear characteristics of the tool inserts. The machining of the EN8 was examined in
this research using silicon carbide tool inserts and Titanium nitride coated tool
inserts. This research was investigated the wear behaviour of the silicon carbide tool
insert, and titanium nitride tool insert in machining of EN8 steel using a horizontal
machining centre. The wear of the inserts was measured using toolmakers
microscope. The flank wear and crater wear was considered in the tool wear
measurement.

Effectiveness of multilayer coated tool in turning of aisi 430 f steeleSAT Journals
Abstract This paper presents minimization of surface roughness in dry turning of AISI 430F steel using TiN-TiCN-Al2O3-ZrCN multilayer coated cemented carbide & cryo-treated inserts. Effect of cutting velocity, feed rate, depth of cut & machining duration is studied on the surface roughness. Taguchi’s design of experiment is used to find the optimum factor levels. It is found that the feed rate has much effect in producing lower surface roughness followed by speed. The depth of cut has lesser role on surface roughness. The result of Taguchi method shows that cutting velocity of 250m/min, feed rate of 0.25 mm/rev and depth of cut of 0.3mm should be maintained as optimal parameter settings for both coated and cryo-treated tools. Cryo-treated tools perform better. Keywords: Cryo-treatment, Dry Turning, Surface roughness, Taguchi Method

Minimization of Material Removal Rate in Abrasive Jet Machining of Tempered G...paperpublications3
Abstract: Modern machining methods are also known as Non Traditional machining methods. These methods form a group of processes which removes excess material by various techniques involving mechanical, thermal, electrical, chemical energy or combination of these energies. There is no cutting of metal with the help of metallic tool having sharp cutting edge. The major reasons of development and popularity of the modern machining methods are listed below.
Need to machine newly developed metals and non-metals having some special properties like extremely high strength, high hardness and high toughness. A Materials poising the above mentioned properties are difficult to be machined by the Conventional machining methods.
Sometimes it is required to produce complex part geometries that cannot be easily produced by following conventional machining techniques .Non
Traditional machining methods also provide very good quality of surface finish, which may also be an encouragement of these methods. There can be a very long list of non-conventional machining methods. These methods can be classified as the basis of their base principle of working as given in the following section.
Investigation of Metal Removal Rate and Surface Finish on Inconel 718 by Abra...AM Publications
Abrasive Waterjet (AWJ) cutting has proven to be an effective technology for material processing with the distinct advantages of no thermal distortion, high machining versatility, high flexibility and small cutting forces. In this paper, Taguchi robust design analysis is employed to determine optimal combination of process parameters. The Analysis of Variance (ANOVA) is also applied to identify the most significant factor. The process parameters such as pressure, transverse speed, stand of distance and abrasive flow rate are optimized to investigate their influence on Metal Removal Rate (MRR) and Surface Roughness (Ra) of Inconel. Experiments are carried out by L9 orthogonal array and the results are provided to verify this approach and credible tendencies of output parameters with respect to the input parameters are discussed, from which recommendations are made for process control and optimization.
Surface Quality Improvement Using Modified Tool Clamping In Boring OperationsIJRES Journal
Boring operations are challenging owing to limited process performance due to inherent tool overhang and resulting vibrations. The tool vibrations can be suppressed with insertion of suitable damping methodology. The present work adopts a method suitable for machine operators, where in insertion of packing sheets at the boring tool support has been suggested. Insertion of number of layers causes frictional phenomenon to dissipate the exciting energy thereby damping the vibrations. Substantial improvement of surface quality of the internally machined surfaces has been noticed in the experiments
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
