Lathe-Types, Parts, Feed Mechanisms, Specifications,Lathe Accessories and Att...rajguptanitw
Who could ever think of manufacturing metals and other materials like wood and plastic without the lathe machine? Since the lathe machine is an important tool used in the machining process, which is an integral process in the manufacturing technology, it is just fitting to learn about it.
Machining is one of the most important material removal methods in the technology of manufacturing. It is basically a collection of material working processes that involves other processes such as drilling, shaping, sawing, planning, reaming, and grinding among others. Machining is practically a part of the manufacture of all metals and other materials such as plastics, and wood as well. An important machine that is useful in machining is the lathe machine.
A lathe machine is generally used in metalworking, metal spinning, woodturning, and glassworking. The various operations that it can perform include the following: sanding, cutting, knurling, drilling, and deforming of tools that are employed in creating objects which have symmetry about the axis of rotation. Some of the most common products of the lathe machine are crankshafts, camshafts, table legs, bowls, and candlestick holders.
The first lathe machine that was ever developed was the two-person lathe machine which was designed by the Egyptians in about 1300 BC. Primarily, there are two things that are achieved in this lathe machine set-up. The first is the turning of the wood working piece manually by a rope; and the second is the cutting of shapes in the wood by the use of a sharp tool. As civilizations progressed, there have been constant modifications and improvements over the original two-person lathe machine, most importantly on the production of the rotary motion.
The production of the rotary motion therefore evolved according to the following procedures: the Egyptians manual turning by hand; the Romans addition of a turning bow; the introduction of the pedal in the Middle Ages; the use of the steam engines during the Industrial Revolution; the employment of individual electric motors in the 19th and mid 20th centuries; and the latest of which is the adaption of numerically controlled mechanisms in controlling the lathe machine.
For the lathe machine to function and perform its operations, various important parts are integrated together. These essentials parts make up the lathe machine.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
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.
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.
2. Drilling
• Drilling is the operation of producing circular hole in the
work-piece by using a rotating cutter called DRILL.
• The machine used for drilling is called drilling machine.
• The drilling operation can also be accomplished in lathe
in which the drill is held in tailstock and the work is held
by the chuck.
• The most common drill used is the twist drill.
3. Drilling Machine

Machining Time (T) :-
It depends upon the length (l) of the hole to be
drilled , to the Speed (N) and feed (f) of the drill
t = L / f N min
26. Precautions for Drilling machine
• Lubrication is important to remove heat
and friction.
• Machines should be cleaned after use
• Chips should be removed using brush.
• T-slots, grooves, spindles sleeves, belts,
pulley should be cleaned.
• Machines should be lightly oiled to prevent
from rusting
27. Safety Precautions
• Do not support the work piece by hand – use
work holding device.
• Use brush to clean the chip
• No adjustments while the machine is operating
• Ensure for the cutting tools running straight
before starting the operation.
• Never place tools on the drilling table
• Avoid loose clothing and protect the eyes.
• Ease the feed if drill breaks inside the work
piece.
