Towards smart and competitive sustainable machiningLiu PeiLing
Computer Numeric Control (CNC) revolutionized the machining technology and has been the cutting edge of digital manufacturing since 1950s. CNC machining model, simulation,
verification, and optimization have been a vivid research topic of Smart Machining that automated the CNC programming (CAM) and cutting process, hence greatly increased machining productivity since 1990s. This paper traces back the history of CNC simulation, analysis the different CNC machining models, tested with application examples, and listed different CNC verification industry applications for the last 20 years. The new challenge comes from sustainable manufacturing. Towards mart and competitive sustainable machining, CNC model and simulation will be used to optimize the machining process, where the raw material could be saved through First Part correct technology, the energy could be saved through cutting speed optimization, and used parts could be saved by remanufacturing.

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.

COLLEGE BUS MANAGEMENT SYSTEM PROJECT REPORT.pdfKamal Acharya
The College Bus Management system is completely developed by Visual Basic .NET Version. The application is connect with most secured database language MS SQL Server. The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.

evolving the design, engineering the product, manufacturing the
part, marketing and servicing.
The product undergoes the following two main processes
Design process
Manufacturing process
5.
6. DESIGN PROCESS
Design is an activity that needs to be well organized and should take into
account all influences that are likely to be responsible for the success of the
product under development.
The following models are considered in design purpose
Shigley
Pahl and Beitz
Ohsuga
Earle
11. SEQUENCIAL ENGINEERING
Three major phases of conventional manufacturing process are design,
process planning and manufacturing.
All these phases are sequentially carried out.

17.
18. COMPUTER AIDED DESIGN
Groover and Zimmers defined “CAD is the technology concerned with the use
of computer systems to assist the creation, modification, analysis and
optimization of a design”.
19. Roles of CAD in Design
Accurately generated and easily modifiable graphical representation of the
product.
User can nearly view the actual product on the screen, make any
modification to it and present his ideas on screen without any prototype,
especially during the early stages of the design process.
Complex design analysis in short time. By implementing Finite Element
Analysis (FEA) methods user can perform as follows
Static, dynamic & natural frequency analysis
Heat transfer analysis
Fluid flow analysis
Plastic analysis
20. Roles of CAD in Design
It records and recalls information with consistency and speed
Use of Product Data Management (PDM) systems can store the whole
design and processing history of a certain product for future reuse and
upgrade.
24. CAD SYSTEM ARCHITECTURE
It is an early model which was used for the basic geometry construction
and modelling purpose.
Four major components of CAD System Architecture are
1. Database
2. Operating system
3. Input/output devices
4. User interface
25.
26.
27. COMPUTER GRAPHICS (CG)
Computer graphics is a technology which uses the display of the drawing or
the geometric model of the component in CAD.
CG may be defined as the process of creation, storage and manipulation of
drawings and pictures with aid of a computer.
It is an extremely effective medium for communication between users and
computers.
There are two types
1. Passive CG
2. Interactive CG
30. ADVANTAGES OF COMPUTER
GRAPHICS
The object drawings can be denoted by its geometric model in three
dimensions. i.e. X, Y, Z coordinates.
Accurate drawings can be made.
Sectional drawings can be easily created.
Modification of geometric model of objects is easy.
It is easy storage and retrieval of drawings.
31. APPLICATIONS OF COMPUTER
GRAPHICS

Image processing
32. CO-ORDINATE SYSTEMS
In general, there are two types of co-ordinate system
1. Cartesian – Linear distances X,Y and Z
2. Polar – Angles such as θ, α, φ
33. Left hand and right hand co-ordinate systems
Multiple co-ordinate systems
World co-ordinate system
Object co-ordinate system
Hierarchical co-ordinate system
View point co-ordinate system

35. 2D & 3D
(GEOMETRIC)TRANSFORMATION
A geometric transformation is an operation that modifies
its shape, size, position, orientation etc. with respect to its
current configuration operating on the vertices.
Some of the important transformations are

46. LINE DRAWING
28-03-2020 46
Straight line segments are used a great deal in computer generated
pictures. The following criteria have been stipulated for line drawing
displays:
i. Lines should appear straight
ii.Lines should terminate accurately
iii.Lines should have constant density
iv.Line density should be independent of length and angle
v.Line should be drawn rapidly
47. DDA ALGORITHM
28-03-2020 47
A popular method uses an algorithm known as “Digital Differential
Analyzer” which generates lines from their differential equations.
For a line segment joining two points P1 and P2, a parametric
representation is given by
P(u) =P1+(P2-P1)u
In terms of x(u) and y(u)
x(u) = x1 + (x2-x1)u
y(u) = y1 + (y2-y1)u
48. BRESENHAM’S LINE ALGORITHM
28-03-2020 48
The basic principle of Bresenham’s line algorithms is to select the optimum
raster location to represents a straight line.
To achieve optimum raster scan, the algorithm always increments either x
or y by one unit depending on the slope line.
The increment in the other variable is determined by examining the
distance between the actual line location and the nearest pixel.
This distance is called decision variable or error.
49. CLIPPING
28-03-2020 49
If any part of the geometry is not inside the window, it is made invisible by
the graphic software is called clipping.
52. VIEWING TRANSFORMATIONS
28-03-2020 52
Displaying an image of a picture involves in mapping the co-ordinates of the
picture into the appropriate coordinates on the device where the image is to
be displayed.
