TIPS FOR A BETTER LAB SESSION
Some of the Best Practices to help the Lab run smoothly while
maximizing Student Learning.
1. Students should be familiar with the Lab exercises before coming to Lab.
2. Students should treat the Laboratory Exercises as original Research.
3. Students should make sure not to miss even a single Lab Class.
4. Students must apply the concepts learned in the class to New Situations.
5. Each student must try to do their Lab Exercises Individually.
6. The instructor will hold a pre-laboratory discussion on the lab exercises.
7. Each student should write the meaning of every command or statement in
the program by using pencil in the empty space. This will help them
understand the concepts more clearly at any point of time.
8. Each student should draw the model for the extra lab exercise questions
given in the manual before every Lab Session.
9. The students should come prepared for Viva based on the questions given
in the lab manual.
10.If the students come unprepared, he/she will not be allowed to do the Lab
exercise and will be marked absent.
11.The progress of every student will be monitored on a regular basis. Based
on the progress report Extra Credit Marks will be awarded for the students
in their Internals.
12.Every student must be able to explain the modeling concepts clearly at the
end of each Lab Session.
13.Labs are for you (students) and so consider it as your duty to use it
perfectly. It’s your responsibility to take care of the computer systems and
the other equipment.

Date
Aim:
To study the 3D Modeling Software.
Introduction
The two dimensional orthographic views have been the conventional method of
representing a product shape. The two dimensional drawings have been very difficult to
understand. By creating three dimensional drawings of engineering components using
advanced software is known as 3D modeling.
Types of 3D Modeling
1. Wireframe modeling
2. Surface modeling
3. Solid modeling
Solid modeling
The difficulties in wire frame and surface modeling are overcome by solid modeling.
Solid modeling is classified in seven types
1. Primitive instancing
2. Generalized sweeping
3. Special occupancy enumeration
4. Cellular decomposition
5. Constructive Solid Geometry(CSG)
6. Boundary Representation (B-rep)
7. Hybrid System
Hybrid System
In the seven methods the hybrid system is an advanced solid modeling contains software
packages, the advantages, of CSG and B-rep are combined.

INTRODUCTION
Computer Aided Manufacturing is to Plan, Manage and Control the
operations of manufacturing plant through either direct or indirect computer
interface with the plant’s production resources. The inventor himself would not
have dream of the use of computers in various fields of life which is drastically
changing the entire scenario of the universe. It is now an integral part of our day
today life. There is lot of research going on with the help of computers in the field
of factory automation. The declining cost of computers coupled with the invention
of Multi task high speed micro processors, really made an industrial revolution and
there seems to be no end for this. A distinct trend can be observed in industries
which include an increase in the use of computer controlled machine tools, the
application of new manufacturing systems, such as laser beam machines and
appearance of new generation of industrial robots in the production line, the
manufacturing management through MRP.
Evolution of Automation
Automatically controlled factory is nothing more than the latest
development in the industrial revolution that began in Europe two centuries ago
and progressed through the following stages.
1. Mechanization started in 1870 at the beginning of industrial revolution
with simple production machines.
2. In 19th Century fixed automatic mechanism and transfer lines came into
existence for faster output and shorter production time.
3. Simple automatic control machines and copying machines were invented
in the later part of the 19th century. After 1950 the industrial
automation was started. In this second phase of the industrial
automation / revolution, workers, instead of physically performing all
the task, are placed in the control of the machines.
Progressive Change after 1950 is as follows
1. The introduction of Numerical Control (NC) in 1952 opened a new era in
automation.
2. The extension of NC was computerized control (CNC) machine tools in
which computer (Micro Processor) is included as an integral part of the
control system.
3. Commercial Industrial robot was manufactured in 1961 along with CNC
systems. The use of these robots, are well utilized only after 1970’s
4. The next logical extension is a fully automated factory which employs a
Flexible Manufacturing Systems (FMS) and Computer Aided Design /
Computer Aided Manufacturing (CAD / CAM) techniques.
51
5. The latest of the above is Computer Integrated Manufacturing (CIM)
which includes battery of CNC machines, with flexible modules, for
manufacturing tool head changers automatic material handling systems
like Automated Guided Vehicle (AGV) etc. with minimum number of
operating personals.
Computer Numerical Control
A dedicated micro processor or minicomputer on the machine control
makes the computer numerical control, very popular, coupled with lots of other
advantages.
Advantages
1. Accuracy and repeatability is very high
2. Reduced Scrap and Work
3. Reduced inspection time
4. Ease of inter changeability of machined parts
5. Reduced space
6. Reduced material handling
7. Less paper work
8. Less lead time
9. Less inventory
10.Easy editing of Programs
11.Complicated shapes and contours are easily manufactured with quality
assurance and better production management.
12.better utilization of machines
13.Reduced tooling
14.Reduced operator skill
15.No jigs and with minimum fixtures
16.Reduced floor space
17.Higher level of integration such as DNC, FMC, AC, CAD / CAM etc.,
Application of CNC
In automobile, aircraft and general Engineering industry, CNC machines are
essential to achieve competitive quality standards.
The following are the common CNC machine available in the industry
1. CNC lathe
2. CNC Milling / Drilling Machine
3. CNC Turning Centre
4. CNC Machining Centre, Multi machining centre
