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.

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.

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. Key :-
A key is a piece of mild steel inserted between the
shaft and hub or boss of the pulley to connect
these together in order to prevent relative motion
between them.
Keys are used as temporary fastenings and are
subjected to considerable crushing and shearing
stresses.
3. Types of keys :-
There are five types of keys :
1) Sunk keys
2) Saddle keys
3) Tangent keys
4) Round keys
5) Splines
4. 1. Sunk Keys :-
The sunk keys are provided half in the keyway of the shaft and half in the keyway
of hub or boss of the pulley.
The sunk keys are following types:
1) Rectangular sunk key
2) Square sunk key
3) Parallel sunk key
4) Gib-head key
5) Feather key
6) Woodruff key
7. Gib-head key :- It is a rectangular sunk key with a head at one end known as
Gib-head. It is usually provided to facilitate the removal of key.
8. Feather key :- A key attached to one member of pair and which permits relative
axial movement is known as Feather key.
9. Woodruff key :- The woodruff key is an easily adjustable key.
:- It is a piece from a cylindrical disc having segmental cross-
section as shown in figure:
10. 2. Saddle keys :-
The saddle keys are following two types :
1) Flat saddle key :
2) Hollow saddle key :
11. 1) Flat saddle key : It is a taper key which fits in a keyway in the hub and is
flat on the shaft. It is likely to slip round the shaft under
load. Therefore, it is used for comparatively light loads.
2) A hollow saddle key : It is a taper key which fits in a keyway in the hub
and the bottom of the key is shaped to fit the
curved surface of the shaft. Since hollow saddle
keys hold on by friction, therefore, these are
suitable for light loads. It is usually used as a
temporary fastening in fixing and setting
eccentrics, cams, etc.
12. Tangent key :- The tangent keys are fitted in pair at right angles. Each key is
to withstand torsion in one direction only. These are used in
large heavy duty shafts.
13. 4) Round keys :- The round keys, as shown in Figure, are circular in section
and fit into holes drilled partly in the shaft and partly in the hub.
They have the advantage of manufacturing as their keyways may
be drilled and reamed after the mating parts have been
assembled. Round keys are usually considered to be most
appropriate for low power drives.
14. 5) Splines :- Sometimes, keys are made integral with the shaft which fit in the
keyways broached in the hub. Such shafts are known as splined shafts.
