1. ADVANCED METHODS
OF BUILDING
CONSTRUCTION
CAD/CAM

2. CAD & CAM’S USE IN
INDUSTRIES
• CAD & CAM IS CONCERNED WITH
APPLICATION OF COMPUTERS TO
VARIOUS DEPTTS. STARTING FROM
DESIGN OFFICE TO PRODUCTION
DEPTT., TO MACHINE SHOPS &
ASSEMBLY SHOPS, TO INSPECTION
& QUALITY CONTROL DEPTTS.,
RIGHT THROUGH TO THE FINISHED
PARTS STORE.

3. COMPUTER AIDED
DESIGNS(CAD)
● CAD can be defined as use of computers to aid the
design process.
● CAD systems are being used in various stages of
design ,development & manufacturing such as
conceptual design, analysis, rapid prototyping,
documentation and manufacturing.
● CAD methods are being used in design of
engineering components, automobiles, aircrafts,
buildings, textiles etc.

5. IMPORTANCE &
NECESSITY OF CAD
● As computers can store & handle large amount of
engg. Data which can be used in various stages of
design, process planning, manufacturing, analysis
etc.
● Complex geometrical shapes can be visually
checked & inspected using 3D models.
● CAD packages can be employed for design
analysis and optimization before actually
implementing the design.
● It makes design modeling and simulation an
easy task.

6. IMPORTANCE & NECESSITY OF
CAD (CONTD.)
● Product design & development cycle can be
markedly reduced which in turn reduces lead
time.
● Design is an interactive process so various
alternative designs can be easily compared using
CAD & the best one can be implemented.

8. COMPUTER AIDED
MANUFACTURING(CAM)
● CAM may be defined as any support that can
be provided by computers in manufacturing
a given product.
● Computers can be used for operation and control
of a manufacturing process.(Direct Role)
● Computers can be used for process planning, NC
part programming, material handling and
storage, inspection, inventory control and quality
control.

9. COMPUTER AIDED
MANUFACTURING (CAM)
𝗈 Cam uses NC( numerical controlled) machines and CNC(
computer numerical controlled ) machines with the help of NC
programs and APT programs.
𝗈 With the help of these programs we can control the motion
of machines such as milling, drilling, cutting etc.
𝗈 In NC part programming we have to enter a
sequence of instructions and machines work
accordingly. For Ex.
M00- PROGRAM
STOP M06- TOOL
CHANGE

11. COMPUTER AIDED
MANUFACTURING
(CA
M)
𝗈 In APT we have to give motion statements
like GOTO, FROM,POINT etc.
𝗈 With the help of CAM, machines work as
per requirement and thus,
1. Increases accuracy and productivity.
2. Reduces cost of production, set up time
and scrap.
3. Reduces direct labour and workpiece.
4. Make design changes and prototypes
making easy

12. INDUSTRIAL
ROBOTS

● Even robots have been designed by using CAD &
CAM methods and controlled by using languages
VAL, ROBEX, AML, HELP etc.

16. AUTOMATI
ON
𝗈It deals with application of mechanical,
electronic, computer and information technology
based systems to operate & control production.
𝗈CAD & CAM are parts of AUTOMATION.
𝗈There are 3 types of AUTOMATION:-
1.Fixed Automation
2.Programmable Automation
3.Flexible Automation
𝗈Industries select a type of automation according
to its different batches of production.

17. BENEFITS OF CAD/CAM
•To increase productivity of the designer
•To improve quality of the design
•To improve communications
•To create a manufacturing database
•To create and test toolpaths and optimize them
•To help in production scheduling and MRP models
•To have effective shop floor control

18. ADVANTAGES OF
CAD/CAM SYSTEMS
● Greater flexibility.
● Reduced lead times.
● Reduced inventories.
● Increased Productivity.
● Improved customer
service.
● Improved quality.
● Improved
communications with
suppliers.
• Better product
design.
• Greater
manufacturing
control.
• Supported
integration.
• Reduced costs.
• Increased utilization.
• Reduction of machine
tools.
