Presentation study of manufacturing process in hmt machine tools limited.docxAbu Sufyan Malik
Manufacturing is the production of products for use or sale using labour and machines, tools, chemical and biological processing, or formulation, and is the essence of secondary industry. The term may refer to a range of human activity, from handicraft to high-tech, but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).
Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made. These materials are then modified through manufacturing processes to become the required part.
The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Cast Parts. Examples in Europe include Volkswagen Group, Siemens, FCA and Michelin. Examples in Asia include Toyota, Yamaha, Panasonic, LG, Samsung and Tata Motors.
This PPT will let you know about metal casting and more specifically about the type of casting that is, Die casting, types of die casting, Cleaning of castings and inspection of casting

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

1. SHEET METAL PROCESSES
Sheet metal characteristics - Typical shearing operations, bending and
drawing operations – Stretch forming operations –– Formability of sheet
metal – Test methods – Working principle and application of special
forming processes - Hydro forming – Rubber pad forming – Metal
spinning – Introduction to Explosive forming, Magnetic pulse forming,
Peen forming, Super plastic forming.
2. Introduction
The working of metal thickness from 3mm to 5mm
with hand tools and simple machines into various
forms is known as sheet metal work.
Sheet metals
Black iron
Galvanized iron
Stainless steel
Brass
Copper
Zinc , Aluminium, tin plate and lead.
15. - Roll Forming
If the edges are formed to a desired shape in the form of bend is
made on the sheet metal
- Seaming
The process of providing lock between the two edges of the
different work metal.
SHEARING OPERATION - DRAWING
- Deep Drawing
Length of the part drawn is deeper then width.
- Box Drawing
Length of the part drawn is lesser then width
16. STRETCH FORMING OPERATION
Stretching is the process of stressing the work blank beyond its elastic limit
by moving a form block towards the blank.
FORM BLOCK METHOD
25. 3.0 METAL SPINNING
a) Manual Spinning
b) Power Spinning
Applications: Ash trays, flower pots, lamp shades, missile and radar units
26. 4).EXPLOSIVE FORMING PROCESSES
- Stand off operations
The explosive charge is located at some distance away from the blank
and energy is transmitted through some fluid medium such as water.
- Contact Operations
The explosive charge is directly located over the blank.
AEROSPACE COMPONENTS
27. Electro magnetic forming
The energy stored in a capacitor bank is discharged
rapidly through a magnetic coil.
EX: a ring shaped coil is placed over a tubular
workpiece.
Depends upon the shape of the die the tube will
deform when the magnetic force pushes the metal.
