Metal inert gas (mig) welding
MIG welding, also known as gas metal arc welding, is a semiautomatic welding process where a continuous wire electrode is fed through a gun and melts upon contact with the base metal. Shielding gas protects the weld from atmospheric contamination. MIG welding is commonly used in manufacturing applications like automotive repair and pipe welding due to its high deposition rate, ability to produce quality welds quickly, and versatility in welding many metal alloys. However, it is limited to flat and horizontal welding positions due to issues with high heat input and weld puddle fluidity in vertical and overhead positions.
Centrifugal casting
Its a class lecture about Centrifugal Casting in Production Process subject. This class held at Khulna University of Engineering & Technology. Class conducted by Md. Abdullah Al Bari.
Shell molding process
Shell mold casting is a metal casting process that uses a resin-coated sand mixture to form a thin-walled mold shell around a metal pattern. The pattern is heated and pressed into the sand-resin mixture to form the shell, which is then cured in an oven. Two shell halves are joined to form the complete shell mold, into which molten metal is poured to create the casting. This allows for high-precision casting of small to medium parts like gear housings, cylinder heads, and connecting rods. The shell mold casting process provides advantages over sand casting like better surface finish and dimensional accuracy for the final casting.

Continuous casting of steel
This is the presentation on Continuous casting of steel, types and defects along with electromagnetic stirrer.
Flash butt welding of rails
The flash-butt welding process involves pressing two rail ends together under high pressure after heating them to melting temperature with a high-current electric arc. This causes the ends to coalesce into an accurate weld without filler metal and with a minimal heat-affected zone. To prevent issues with track geometry after cooling, the rail ends are given a slight upward inclination matched to the rail profile. Flash-butt welding produces welds with strength nearly equal to the parent rail and a very low failure rate compared to other welding methods like aluminum thermic welding. Mobile flash-butt welding machines can perform this process automatically on site along rail lines.

Rotational moulding
Rotational molding is a process used to create large, hollow plastic parts with uniform wall thickness. It is the only hollow parts process that can produce extremely large parts. The material is heated and rotated inside a mold to distribute it evenly. This allows for flexible designs by combining parts into one. Advantages include low-cost tooling, stress-free parts, and uniform thickness. However, cycles times are very long, ranging from 8-40 minutes. Also, only certain materials can be used and warping may occur without precise cooling. Competing processes like blow molding and injection molding have shorter cycles but cannot produce parts as large. Future developments include new materials, automation, and adding internal cooling.
Foundry
This document provides information on foundry processes and sand casting. It defines important casting terminology like flasks, drags, copes, patterns, and parting lines. It describes the tools used in sand mold making like molds, hammers, and trowels. It explains the procedure for making a sand mold in steps from preparing the bottom board and drag to applying facing sand in the mold cavity. It also defines different types of molds like green sand molds, dry sand molds, and skin dried molds. The document outlines properties of molding sand and types of patterns used in casting.
Casting and welding technology
Hot forming processes, such as die-casting, investment casting, plaster casting, and sand casting, each provide their own unique manufacturing benefits. Comparing both the advantages and disadvantages of the common types of casting processes can help in selecting the method best suited for a given production run.
Continuous casting
Continuous casting is a process used to cast metal into a continuous length. Molten metal is poured into a mold and solidifies into a casting as it travels downward. New molten metal is continuously supplied to the mold to keep the process going and produce a casting of indefinite length. The process requires precise control of parameters like molten metal flow to ensure smooth, continuous casting.
Bloom, billet, slab, plate
Bloom, billet, slab, plate, sheet, strip are terms used in metalworking and manufacturing. Blooms undergo first breakdown of ingots through hot working and have a large cross sectional area. Billets are further reduced through hot rolling. Slabs are hot rolled ingots with a specific cross sectional area and width. Plates are thick products over 6mm, while sheets are thinner but wide, and strips are thin and narrow. Blooms, billets, and slabs are considered semi-finished products.
Chapter 8 powder metallurgy
Powder metallurgy is a process for manufacturing parts from metal powders by compacting and sintering. Key steps include producing metal powders through methods like atomization or chemical reduction, blending powders and lubricants, compacting the blended powder in a die under pressure to form a green compact, and sintering the compact at high temperatures to bond the powder particles. The sintered parts have properties that cannot be achieved through conventional manufacturing and the process allows for high precision and low waste production of simple parts.
Die casting
Die casting is a process where molten metal is injected into a steel die under high pressure to form complex shapes. Common metals used include aluminum, magnesium, and copper alloys. The die is made of steel and consists of two halves, with one half fixed and the other movable. During die casting, molten metal is injected into the die cavity using pressures up to 9,800 psi and solidifies into the final part. Die casting allows for high production rates and close dimensional tolerances of the parts produced.
Super plastic forming and explosive forming
Super plastic forming is a metalworking process that uses high temperatures and controlled strain rates to form sheet metal. Materials like titanium alloys and aluminum alloys can elongate several times their original length through this process. Explosive forming also shapes metals through high pressure, using an explosive charge to form sheet metal against a die in either a standoff or contact method. Both processes allow for complex shapes but super plastic forming is slower while explosive forming supports larger parts and shorter production runs.
Metal Joining Processes
The document discusses various metal joining processes, focusing on welding. It describes different types of welding processes, including arc welding, gas welding, resistance welding, and solid state welding. For arc welding processes specifically, it explains gas metal arc welding (MIG), shielded metal arc welding (SMAW), submerged arc welding (SAW), and the consumable electrodes, shielding gases, and power sources used.
Injection moulding
Injection molding is a manufacturing process that uses molds to produce plastic or rubber parts. Molds are hollow blocks that give the part its shape and allow it to cool. Thermoplastics can be molded repeatedly while thermosetting plastics set permanently after one molding. Injection molding machines consist of a hopper, barrel with a reciprocating screw, nozzle, and molds. The process involves melting plastic in the heated barrel and injecting it into the mold under pressure before allowing it to cool into the final shape.
Pattern making
Metal patterns are commonly used for machine molding due to their strength, accuracy, and resistance to warping, moisture, and abrasion compared to wood patterns. Common metals used include aluminum alloys, steel, cast iron, and brass. Plastic patterns are also used and provide benefits such as being lightweight, durable, and corrosion resistant, but can be more fragile. The appropriate type of pattern depends on factors like the production quantity, part complexity, molding method, and potential design/molding problems. Common pattern types include one-piece, split, match-plate, cope and drag, loose piece, sweep, and skeleton patterns.
Gas Metal Arc Welding (GMAW)
Gas Metal Arc Welding or MIG welding .
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join

Rolling,Rolling mills,Rolling processes &Rolling Applications by polayya chin...
The document discusses rolling as a metal forming process. It describes rolling as a process where metal is passed between circular cylinders to change its shape through plastic deformation. Both hot and cold rolling processes are used, with hot rolling used for more drastic shape changes. Different types of rolling mills are covered, including two-high, three-high, four-high, cluster, and planetary mills. The advantages and disadvantages of rolling and its applications in producing items like tubes, rods, gears, and construction materials are also summarized.
Full Mould Casting Process
Full mould casting is a casting process that uses an expanded polystyrene foam pattern surrounded by sand. Molten metal is poured directly into the mould, vaporizing the foam and allowing the metal to fill the entire mould cavity. This process is similar to lost wax casting but uses a thermally decomposable foam pattern instead of wax. The foam pattern can be designed using computer tools before the casting process. Some advantages are it is cheaper than investment casting, requires no drafts or risers, and has good dimensional accuracy and surface finish.
6.core
Cores are used in casting to produce hollow spaces or internal features. There are different types of cores classified by their material, production process, or placement in the mold. Dry sand cores are made separately from the mold using core sand, then baked to harden. Key steps in core production are preparing core sand, making the cores using a core box, baking the hardened cores, and finishing before placement in molds. Cores allow castings to have complex internal or recessed features.
CUTTING TOOL SELECTION
Cutting tools require materials with high hardness, strength, and wear resistance at elevated temperatures. Common tool materials include high-speed steels, cast cobalt alloys, tungsten carbide, and coated tools. Newer coated tools can last 10 times longer than uncoated tools due to coatings like titanium nitride which provide lower friction and higher resistance to cracks and wear, allowing higher cutting speeds.
Squeeze Forming or Squeeze Casting Process
It is a near net shape process in which casting and forging is done in single step.
It is Referred by many names such as “squeeze casting” , “pressure infiltration”, “liquid metal forging”, “extrusion casting”, “liquid pressing'', “pressure crystallization”.
Laser Beam Welding
This document discusses laser beam welding, including what a laser beam is, the different types of lasers, and the laser beam welding process. It describes how laser beam welding works by focusing an intense laser beam onto metal workpieces to melt and join them. The document outlines the history of lasers from Einstein's theories to developments in the 1970s-2000s. It also explains the principles and setup of laser beam welding, the different types (conduction and keyhole welding), applications, and provides an example of repairing nuclear power plant components using ND:YAG laser welding.
Permanent mold casting
This document discusses permanent mold casting. Permanent mold casting uses metal molds that are repeatedly used to produce many castings of the same form. The liquid metal enters the mold by gravity. It is used for high volume production of small, simple parts made of non-ferrous metals like aluminum alloys. Common applications include gears, housings, and automotive and aircraft parts. The process yields castings with good mechanical properties, dimensional tolerances, surface finishes, and production rates. However, it requires expensive tooling for low volumes and some part shapes cannot be molded.
Welding fixtures
The document discusses various types of tooling used for joining processes like welding, brazing and soldering. It describes different considerations for designing fixtures for gas welding, arc welding and resistance welding. Fixtures need to hold parts in proper alignment, allow for heat control and prevent distortion. Materials must withstand high temperatures and properly direct heat flow. The document also discusses workholding principles and tooling designs for CNC machines.

Introduction to Information Security
Most of today's security attacks target digital information and systems because:
- More information and transactions are conducted online, providing more opportunities for attackers. As society has become more digital, so have the targets and means of attacks.
- Digital systems and data tend to be more accessible than physical assets. With ubiquitous internet connectivity, it is easier for attackers to remotely access networks, systems and information without needing physical proximity or access.
- Attacks on digital systems can potentially impact many more victims since data is often centralized. A single digital intrusion or exploitation can affect thousands or millions of users rather than a single physical target.
- There is perceived anonymity in digital attacks. Attackers may feel less accountable or identifiable launching digital attacks

polymer processing ppt
Polymer processing involves converting plastic raw materials into finished products. There are primary, secondary, and tertiary processing methods. The selection of a processing method depends on factors like the product design, material properties, production quantity, and cost. Common primary methods include injection molding, extrusion, blow molding, and compression molding. The polymer properties like water absorption, physical form, thermal stability, and melt flow properties affect the suitable processing technique. Proper consideration of these factors ensures efficient processing and quality product manufacture.

IRJET- Development of Ejection System to Improve Productivity
This document describes a project to improve the ejection system of an injection molding machine to increase productivity. The existing system uses two ejectors but takes a long time (80 seconds) per cycle. The proposed new system adds two additional ejectors on the front corners. This allows the molded component to be ejected with only one stroke, reducing the cycle time to 54 seconds. Calculations show the production rate increased by 48% with the modified system. Benefits include balanced ejection, eliminating component catching issues, and improved part quality. The objectives are to reduce ejection time, cycle time, and improve production rate and efficiency.
IRJET- Development of Ejection System to Improve Productivity
This document describes a project to improve the ejection system of an injection molding machine to increase productivity. The current machine uses two ejectors but it takes a long time and worker effort to remove molded components from the mold. The project aims to add two additional ejectors positioned at the corners of the ejector plate so that only one stroke is needed to eject components. This is expected to reduce ejection time, cycle time, and worker effort, while increasing production rates and part quality.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.
